What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

• list_facets

  The filter vocabulary with real counts (number of flows): platform, flowIntents, uiComponents, pageType and screenPatterns. Call this before filtering search_screens or search_flows so filters are real values, not guesses. Optional query/filters narrow every count, flowIntents in

• get_screen

  One catalog screen with its image and structure. Returns an image block (look at it for color, typography and spacing) and JSON with app, flow, platform, pageType, screenPatterns, uiComponents, keyTexts, dimensions, capturedAt and `elements` (OCR text and hotspots with normalized

• search_screens_by_image

  Find catalog screens that look like your images (base64, e.g. a screenshot of the app you are building). Then call get_screen on the matches to compare. Free plans: up to 2 images and 12 results.

• search_screens

  Search individual UI screens by description, app name or site ('paywall with annual plan first', 'Spotify', 'linear.app'). Returns metadata per screen; set includeImages to also get the top screens as images (max 4, ~1-2k tokens each). Call get_screen for the full structure of on

• search_flows

  Search whole flows (ordered screen sequences) by intent, app or description. Then get_flow for the steps.

• search_emails

  Search real product emails (welcome, receipts, onboarding, re-engagement…) by description or brand. Each result is one email with its desktop and/or mobile image; when hasHtml is true, get_email_html returns the original HTML to adapt. Needs Pro.

• get_email_html

  The original HTML of one email from search_emails (tables, font fallbacks, dark mode included). Adapt it to the user's brand instead of writing email HTML from scratch. Pro, or this week's free flows.

• search_apps

  Find apps in the catalog by name, website or theme ('nubank', 'linear.app', 'meditation').

• get_app

  Metadata for one app in the catalog. Accepts an appId or a slug like 'spotify'. get_app_flows lists its flows.

• get_app_flows

  The flows of one app (onboarding, checkout, settings…) in order, with capture date. Accepts an appId or slug. Big apps have hundreds of flows: page with offset. Then get_flow for the steps of one.

• similar_apps

  Apps like this one, ranked from the app's own flow themes. Accepts an appId or slug.

• get_flow

  One flow with every step in order. Compact by default: each step has screenDocId (for get_screen), pageType, patterns, components and keyTexts. include 'elements' adds OCR/hotspot boxes per step (large: tens of thousands of tokens for a long flow); 'connections' adds step links.

• get_flow_history

  Earlier captures of the same flow (how it changed over time): capture date, screen count and up to 3 preview images each.

• similar_screens

  Screens that look like a given screen. Visual, not keyword — no quota. includeImages returns the top matches as images (max 4).

• list_categories

  The catalog's category rail for a platform, with the key list_apps filters by. Emails, games, store listings and ads have their own rails.

• list_apps

  Apps in the catalog, optionally filtered by category key (from list_categories) or platform. Platform `email` lists brands with email galleries.

• list_projects

  The caller's projects, newest first.

• get_project

  One project with its screens, positions and connections.
