sleek-design-mobile-apps
AI-powered mobile app design tool with REST API for creating projects, describing designs in plain language, and rendering screens.
- Supports high-level requests ("design a fitness app") and specific edits ("add a pricing section to this screen"); send natural language descriptions via chat messages and let the AI decide what to create or modify
- Requires Pro+ plan and API key with scoped permissions (
projects:read/write,chats:read/write,screenshots,components:read) - Async and sync modes available; async returns immediately with a run ID for polling, sync blocks up to 300 seconds
- Always screenshot newly created or updated screens after each chat run and deliver them to the user; combine all project screens into one screenshot when screens are created for the first time
- One active run per project at a time; retry failed requests safely using idempotency keys
Designing with Sleek
Overview
sleek.design is an AI-powered mobile app design tool. You interact with it via a REST API at /api/v1/* to create projects, describe what you want built in plain language, and get back rendered screens. All communication is standard HTTP with bearer token auth.
Base URL: https://sleek.design
Auth: Authorization: Bearer $SLEEK_API_KEY on every /api/v1/* request
Content-Type: application/json (requests and responses)
CORS: Enabled on all /api/v1/* endpoints
Parsing responses: write the body to a file (curl -o run.json) and parse the file. Don't pipe JSON through echo: in zsh it expands the escaped \n inside string values into real newlines, which makes the body invalid JSON.
API docs: OpenAPI spec at https://sleek.design/api/v1/spec.json; browsable docs at https://sleek.design/api/v1/docs. Fetch the spec for any contract detail not covered here.
