  • appstore_compare_marketsCompare an App Store listing across marketsread-only

    Looks up one app (by numeric App Store id, or a pasted apps.apple.com URL) in up to 30 App Store storefronts in a single call, via Apple's public iTunes Lookup API, and reports per-market availability, localized title, price and rating. Capped at 30 storefronts per call by design -- there are 173 total App Store storefronts, and this deliberately never sweeps all of them in one call; call again with a different storefronts list to cover more markets. Lookups run one at a time with a short pause between each (matching the pacing the source browser tool uses for its 30-market quick-compare), so …

  • appstore_searchSearch an App Store storefrontread-only

    Searches one Apple App Store country storefront by term, via Apple's public iTunes Search API (the same request the GO AI "App Store storefront checker" tool makes from the browser), and returns matching apps with title, seller, price, rating and a direct App Store link. Returns up to 200 results, Apple's own per-request maximum -- a result of exactly 200 likely means more exist. Results are ordered by Apple's internal relevance, which does not match the ranked list shown in the App Store app, so this cannot be used to track keyword rank.

  • bpm_delay_calculatorBPM tap tempo & delay time calculatorread-only

    Resolves a musical tempo — either a direct BPM, or a set of tap timestamps/intervals run through the same median-filtered outlier rejection and 2-second session-reset logic as GO AI's tap-tempo tool — then returns the full straight/dotted/triplet delay and LFO-rate table (ms and Hz) for a set of note divisions, plus bar-length and bars<->seconds conversion for a time signature. All arithmetic (not a real audio engine) — useful for setting delay/reverb/LFO times to a track's tempo.

  • build_app_privacy_labelBuild an App Store privacy label checklistread-only

    Given which SDKs and features are present in an iOS app (analytics, crash reporting, ads, attribution, accounts, in-app purchases, location, HealthKit, contacts, search, etc.), returns the App Store Connect privacy data types those items most likely require declaring, grouped the way Apple groups them (Contact info, Identifiers, Usage data, Diagnostics, ...), each with the reason (which chosen item(s) caused it), plus whether App Tracking Transparency/tracking applies and the vendor-documentation date the mapping was checked against. This is a fixed, deterministic lookup table shipped with GO …

  • build_app_store_linkApp Store campaign link builder + QR coderead-only

    Builds a correct apps.apple.com URL for an app ID or a pasted App Store URL, in a chosen two-letter storefront, with optional App Store Connect campaign attribution parameters (pt, ct, and mt=8). Always returns the assembled URL and a params table describing what each part does. When includeQr is true, also renders the URL as a QR code PNG using the same hand-rolled, dependency-free Reed-Solomon byte-mode encoder (error-correction level M, versions 1-10) the source browser page draws to its own <canvas> -- not a generic QR library, so the module layout, masking, and pixel output match that pag…

  • calculate_app_store_net_revenueApp Store net revenue calculatorread-only

    Computes what a developer actually receives from an App Store sale: first removes the storefront's VAT/GST already baked into the customer-facing sticker price, then applies Apple's commission (standard 30%, Small Business Program 15%, or the post-year-one subscription 15%) to that tax-exclusive remainder -- NOT to the sticker price itself, which is the mistake most naive calculators make. Returns a full price breakdown, the effective share of the sticker Apple actually keeps, a side-by-side comparison across all three commission rates (including per-1,000-sales figures), a naive-calculator sa…

  • calculate_bmi_and_body_fatBMI and Navy body fat calculatorread-only

    Computes BMI (with its standard weight-category label) and body fat percentage via the US Navy circumference method from height, weight, neck, waist, and (for females) hip measurements, plus the resulting lean body mass. The Navy equations are fitted in inches, so metric inputs are converted internally; the body-fat percentage is clamped to 2-75% and rounded to a whole number, matching GO AI's body-fat tool page exactly, including its 'waist must exceed neck (and hip, for the female formula)' impossible-input warning and its out-of-fitted-range caution for raw results below 4% or above 60%.

  • calculate_tdeeTDEE & macro calculatorread-only

    Calculate Basal Metabolic Rate with Mifflin-St Jeor and Harris-Benedict (plus Katch-McArdle when body_fat_percent is given), then Total Daily Energy Expenditure, a goal-adjusted calorie target (cut/maintain/bulk), and a protein/fat/carb macro split, from sex, age, height, weight and activity level. These are population-average formulas, not a measurement of the person's actual metabolism -- real expenditure commonly varies 200-300 kcal from the estimate, and the result includes a warning flag when a deficit target falls below the usual safety floor.

  • check_contrastWCAG/APCA contrast checkerread-only

    Computes the WCAG 2.x contrast ratio between a foreground (text) and background hex colour, and reports AA/AAA pass or fail for normal text, large text, and UI components (icons/borders/focus rings) separately, since WCAG grades each case on its own threshold. Also reports the newer APCA Lc figure alongside it for information -- APCA is not yet what conformance is measured against, only the WCAG ratio is.

  • check_strings_filesiOS .strings localization checkerread-only

    Compares two or more iOS Localizable.strings files (sent as base64-encoded raw file bytes, not text) against a base file and reports keys missing from each other file, keys present in another file but not the base ("extra", reported but not counted toward the issue total), values byte-identical to the base (often untranslated, sometimes intentionally so), duplicate values under different keys within the same file (case- and trailing-punctuation-insensitive), and lines that fail to parse with their line number. Sniffs a UTF-8 or UTF-16 LE/BE byte-order mark per file so files exported by Xcode i…

  • convert_heic_to_jpg_pngConvert HEIC/HEIF to JPG or PNGread-only

    Converts iPhone HEIC/HEIF photos to JPEG or PNG, decoding with a WebAssembly build of libheif (LGPL-3.0) and re-encoding with sharp -- the same pipeline as GO AI's browser-based HEIC converter tool, run server-side. Accepts 1-50 files as {filename, dataBase64} (each up to ~30MB decoded); every file is byte-sniffed by its actual magic bytes, never by filename extension or claimed mime type, so an iPhone photo that iOS already delivered as a JPEG (picked from Photos rather than Files) is detected and reported as already_converted -- passed through unchanged, not re-encoded -- while real HEIC/HEI…

  • convert_video_to_gifTrim a short video into a GIF, MP4 or WebMread-only

    Ports GO AI's browser Live Photo-to-GIF tool server-side: trims a SHORT video clip and converts it to an animated GIF, or (a server-side addition the browser tool cannot do) a real MP4/WebM video. Input is base64 video bytes plus its mimeType (any container/codec this server's ffmpeg build can decode) and a trim range in seconds (startSeconds/endSeconds). HARD LIMITS -- this runs in a 400 MB container on one shared vCPU behind a proxy that hangs up at 125s, so an over-budget request is REJECTED up front with a message naming the limit rather than accepted and then killed. Read these before c…

  • css_clamp_calculatorCSS clamp() Calculatorread-only

    Generates a CSS clamp() declaration (in rem) that linearly interpolates a size between a value at a small viewport width and a value at a large one, exactly matching GO AI's clamp() calculator tool (same slope/intercept math, rounded to 4 decimal places). Returns a status: 'sameViewports' when the two viewport widths are equal (no line can be drawn -- css is null), 'flat' when the min and max sizes are equal (a constant, clamp() unneeded), 'inverted' when the max size is smaller than the min (still valid CSS, but the computed size shrinks as the viewport grows), or 'ok' otherwise. Optionally e…

  • estimate_ai_tokensEstimate AI token count, context fit & costread-only

    Heuristic estimate (NOT a real per-model BPE tokenizer) of how many tokens a piece of text will become, ported from GO AI's browser-side token counter. Blends a chars/4 and words/0.75 baseline with surcharges for punctuation, digits and non-Latin script; typically within ±10-15% for ordinary English prose and ±15-25% when non-Latin script is detected -- code and heavily punctuated text tend to tokenize denser than this suggests. Also reports whether the text fits a set of context windows (default: 8K/128K/200K/1M/2M tokens, or pass your own) and, if you supply per-million-token prices, an esti…

  • estimate_window_lightWindow light estimator for houseplantsread-only

    Estimates the indoor light level a window gives a plant, in the category words houseplant care guides use (Direct sun / Bright indirect / Medium light / Low light / Too dark), from the window's hemisphere, compass aspect, what obstructs it, and how far back the plant sits from the glass. This is a small heuristic scoring table ported from GO AI's window-light tool page, not a physical light-meter reading or a per-location sun-position model — it correctly flips which compass direction is 'bright' for the southern hemisphere and flags the direct-west-sun scorch risk, and returns the reasoning b…

  • find_nearest_passing_colorNearest WCAG-passing colour (hue-preserving)read-only

    Given a foreground/background hex pair, moves only the lightness of one side (hue and saturation held fixed) in the smallest step that clears a target WCAG contrast ratio, so a failing brand colour can be fixed without draining its hue. Defaults to the 4.5:1 normal-text AA threshold, matching the source page's fix buttons; pass a named threshold ('normal-aa', 'normal-aaa', 'large-aa', 'large-aaa', 'ui-aa') or a custom numeric ratio to target something else. Reports found:false when even pure black or white in that hue cannot reach the target -- that pair needs a different hue, not a different …

  • generate_app_icon_setApp icon set generator (iOS + Android)read-only

    Turns one source image into a ZIP containing a complete iOS Xcode AppIcon.appiconset (AppIcon.png at 1024x1024, plus a hand-written Contents.json Xcode accepts, and optionally AppIcon-Dark.png and AppIcon-Tinted.png for the appearance variants modern iOS asks for), a full Android mipmap-mdpi/hdpi/xhdpi/xxhdpi/xxxhdpi set of ic_launcher.png files (48/72/96/144/192px), and a flat sizes/ folder with 24 icon-<px>.png files from 16 to 1024px. Any transparency in the source is flattened onto the given background colour first (Apple rejects icons with alpha). A non-square source is centered and lette…

  • generate_favicon_setGenerate a favicon and web-app-manifest setread-only

    Turns one source image into a complete favicon set: favicon.ico (a real multi-resolution ICO container holding 16, 32 and 48px PNG-encoded entries -- not a single-size file with an .ico extension), favicon-96x96.png, apple-touch-icon.png (180px, flattened onto backgroundColor because iOS paints transparency black there), web-app-manifest-192x192.png and web-app-manifest-512x512.png (optionally padded to Android's maskable safe zone -- the artwork shrunk to a centred 80%-width square on the background colour, reproducing the source tool's square padding rather than clipping to the actual inscri…

  • image_compressCompress an image (JPEG/WebP/AVIF)read-only

    Downscales an image to fit within a maximum dimension (default 1600px on the longer side, never enlarges -- matching GO AI's browser compressor tool) and re-encodes it as JPEG, WebP or AVIF at a given quality (1-100 scale, default 75). Input is base64-encoded image bytes (any format sharp/libvips can decode: JPEG, PNG, WebP, AVIF, GIF, TIFF, ...), not a file path or URL, capped at this server's input size limit. Returns the compressed image bytes plus a stats object: original and compressed dimensions and byte sizes, and the percent size change (positive = smaller, negative = the re-encode cam…

  • image_compression_curveImage compression size-vs-quality curveread-only

    Analysis-only tool (no image bytes returned): re-encodes an image at the same fixed 14 quality levels GO AI's browser compressor samples to draw its size-against-quality curve (5, 10, ..., through 100 -- see the qualities in each returned point), for JPEG, WebP or AVIF, and reports the resulting byte size and percent change at each level. The image is first downscaled to fit within maxDimension (default 1600px on the longer side, never enlarged), exactly as the source's working canvas is, then every quality level is encoded one at a time. Because this repeats the encode 14 times, its maxDimens…

  • inspect_mobileprovisionInspect a provisioning profileread-only

    Reads an iOS/macOS provisioning profile (.mobileprovision or .provisionprofile, given as base64) by byte-searching its CMS/PKCS7-signed container for the embedded '<?xml ... </plist>' property list and parsing that XML -- it never validates or decodes the cryptographic signature, and does not report on the embedded certificates beyond how many there are. Reports expiry status and days remaining, profile type (development/ad hoc vs. enterprise vs. App Store distribution, classified only from the registered-device list and the ProvisionsAllDevices flag), team and application identifiers, the ful…

  • oklch_convertConvert an OKLCH / hex / RGB / HSL colorread-only

    Converts a color to and from OKLCH. Accepts either a CSS color string via `color` (hex, rgb()/rgba(), hsl()/hsla(), or oklch()) or explicit OKLCH lightness/chroma/hue via l, c and h — supply one or the other. Returns the canonical oklch() text for the color exactly as requested, plus its sRGB-gamut-mapped hex/rgb()/hsl() equivalents. Gamut mapping follows the CSS Color 4 algorithm (bisecting on chroma at constant lightness and hue, not channel-clipping) and only targets sRGB — there is no P3 or Rec2020 support.

  • oklch_rampBuild an OKLCH swatch ramp / CSS custom-property blockread-only

    Builds a perceptually even OKLCH swatch ramp from a base color (same `color` or l/c/h input as oklch_convert) by sweeping one channel — hue, lightness, or chroma — while holding the other two fixed, so every swatch keeps the same visual weight (this is the reason to build a ramp in OKLCH rather than HSL). Each step is gamut-mapped to sRGB with the CSS Color 4 chroma-reduction algorithm and returned with its hex preview, plus a ready-to-paste `:root { --name-1: oklch(...); ... }` CSS block.

  • plant_watering_calendarPlant watering calendar (.ics)read-only

    Builds a soil-check interval per houseplant from a fixed drought-tolerance table (32 common houseplants), adjusted by pot size, pot material, light and season, and returns both a schedule breakdown and the full text of a downloadable RFC 5545 .ics calendar file -- one recurring all-day 'check the soil' reminder per plant (deliberately never 'water', since only the plant's own soil can say that). Matches GO AI's browser watering-calendar tool exactly, including its northern-hemisphere-season default when `season` is omitted, its terracotta/glazed/low-light/winter multipliers, and its 75-octet .…

  • project_weight_goal_dateWeight loss goal-date projectorread-only

    Projects the calendar date a goal body weight is reached under a fixed daily calorie intake. Unlike a naive straight-line calculator (kg to lose x 7700 / deficit, also returned here for comparison), this recomputes Mifflin-St Jeor maintenance calories at each simulated day as weight falls, so the effective deficit narrows the way it really does -- meaning the projected date is later than, or equal to, the naive one, never earlier. Refuses to project a date when the resulting intake falls below a 1500 kcal (men) / 1200 kcal (women) floor, and reports a 'plateau' outcome instead of a date when t…

  • recipe_convert_ingredientCup-to-grams converter (per-ingredient density)read-only

    Converts an amount of one ingredient between cup, tablespoon, teaspoon, millilitre, gram and ounce using that specific ingredient's own USDA FoodData Central portion weight, not a single water-based figure applied to everything -- a cup of flour (125 g) and a cup of honey (339 g) do not weigh the same. Supports an ingredient's own measurement-style variants where USDA publishes more than one (packed vs loose brown sugar, sifted vs unsifted powdered sugar, whole vs sliced/slivered/ground nuts, etc.), and for baking powder, baking soda and yeast uses USDA's own published teaspoon weight rather t…

  • recipe_scaleRecipe servings scaler with gram weightsread-only

    Scales a pasted recipe (one ingredient per array entry, e.g. '2 cups all-purpose flour') from one servings count to another, multiplying each line's leading amount by the ratio and reformatting it as a whole number or simple/mixed fraction rather than a decimal. When a line's unit and ingredient can both be recognised against GO AI's density table, appends the scaled amount's weight in grams in parentheses; lines already given in grams or ounces, lines whose ingredient isn't recognised, and lines that don't start with a parseable amount are returned unchanged (the last completely as-is, typos …

  • recommend_ai_modelRecommend which AI model to use for a taskread-only

    Static editorial recommendation -- NOT a live benchmark or leaderboard -- for which of six AI models (GPT-5, Gemini, Grok 4, Claude, DeepSeek, Kimi) to use for a given kind of task, ported from GO AI's own daily side-by-side-use judgement, current as of August 2026. Pick a task and get the recommended model plus the reasoning and a second-opinion backup. The optional `priority` can bias the pick toward cost (routes to DeepSeek) or freshness (routes to Grok) instead of the default quality pick -- but only for tasks where that tradeoff is actually offered; otherwise the quality default is return…

  • render_app_store_screenshotApp Store screenshot generatorread-only

    Composite one or more app screenshots into a drawn device frame (rounded bezel, Dynamic Island on phone-shaped canvases) with a gradient background and optional headline/caption text, and export as PNG at any/all of the 4 official App Store Connect sizes. A blank page (image omitted) draws no device, for a title card or an outro. A device positioned past the edge of its page is drawn spilling onto the neighbouring page too, so a set can run one screenshot into the next. LIMITS — this runs on a small shared host, so an over-limit call is refused immediately, before any rendering, with a message…

  • resize_imagesBatch image resizer with real presetsread-only

    Resizes a batch of 1+ images to a named real-world preset (App Store screenshots, Open Graph/social cards, Android launcher icon densities, a favicon set) or a custom width/height, using contain (whole picture, padded), cover (fills the frame, crops overflow) or stretch (distorts to fit) fitting. Each resized image is PNG-encoded (EXIF/ICC metadata stripped on re-encode, matching the source page) and every image is auto-rotated per its embedded EXIF orientation before resizing. All outputs are packaged into one uncompressed ZIP (PNG bytes are already compressed, so a second pass would not shri…

  • strip_image_metadataStrip image metadata (EXIF/GPS/XMP/IPTC/PNG text)read-only

    Reads a JPEG or PNG's hidden metadata (JPEG: EXIF — camera make/model, lens, body/lens serial numbers, capture date, GPS coordinates and altitude — plus XMP, IPTC/Photoshop resources and comment segments; PNG: tEXt/iTXt/zTXt/eXIf/tIME chunks) and returns a structured report of exactly what it found, including the size of every metadata segment/chunk that was removed. Optionally (include_cleaned_image, default true) also returns the same image with those segments/chunks stripped at the byte level: no re-encoding and no pixel decode, so the compressed image data, ICC profile, and JFIF/PNG struct…
