Stitch Export

Export Stitch conversations in LLM-compatible formats (Claude Code, OpenAI ChatGPT)

Stitch Export is a Chrome extension that exports your conversations and generated designs from stitch.withgoogle.com — Google's AI-powered UI design tool — to formats compatible with Claude Code, ChatGPT, and any LLM workflow. ## What it does • Export single conversation — extract the chat history of the current Stitch project as a structured JSON file. Supports Claude Code, OpenAI ChatGPT, and a customizable role-mapping format. • Export all projects (batch) — with one click, archive every Stitch project you've ever created into a single ZIP. Each project folder contains: - chat.json — full per-turn conversation with references to the designs generated in each turn and the follow-up suggestion prompts - screens/ — final HTML designs (current state) - history/turn-NNN-{slug}/ — designs generated in each individual conversation turn, preserving the full history • Icon badge — at a glance, see how many projects you have on Stitch (badge on the toolbar icon) and a small "EXP" reminder when you're on a project page that you can export it. ## How it works The extension uses Stitch's own batch API endpoints to fetch project data, screen instances, and chat sessions. HTML files are downloaded directly from Google's content CDN. No screen scraping, no UI automation — the batch export of 70+ projects completes in about 30 seconds. Your Stitch login session is used (via cookies) — the extension never sees or transmits your password. No external servers are contacted other than Google's own Stitch backend. ## Use cases • Archive your Stitch design history before it's lost • Feed Stitch-generated designs as context to other LLMs • Compare different design iterations across conversation turns • Backup designs for offline reference ## What's new in v1.2.0 • Batch export now uses Stitch's API directly — 24× faster than v1.1.x • Rich chat export — every assistant turn now includes references to the designs it generated and the follow-up suggestion prompts • New ZIP structure with screens/ (final state) + history/ (per-turn designs) + chat.json (full metadata with file references) • Toolbar icon badge — project count on the list page, export reminder on project pages • Refreshed icon set in the new purple/mauve theme ## Privacy This extension: • Runs only on stitch.withgoogle.com and Google CDN domains • Uses your existing Stitch session — no separate authentication • Stores nothing remotely — exports are local downloads only • Collects no analytics, no telemetry, no usage tracking Source code: https://github.com/nsozturk/stitch-export Support: support via GitHub issues
