Superpower for AI
A single capable developer can build a useful, local browser-extension replacement (folders, prompt library, exports, shortcuts and simple prompt rewriting) in about a week and maintain it cheaply; you’d lose the vendor polish, distribution and built-in Drive sync unless implemented.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Inject UI into gemini.google.com to add folders and prompt library, let user save/open prompts, export chat contents to PDF/DOCX/TXT, add keyboard shortcuts and UI tweaks, and implement a local client-side prompt-optimizer (rewrite templates) with optional Google Drive sync via OAuth.
What it still won’t have
- Polished UI/UX and cross-device license management provided by the vendor
- Vendor support, refunds handling, and curated feature roadmap
- Chrome Web Store distribution, reviews, and discovery
- Built-in Google Drive sync implementation unless you implement Drive OAuth and storage yourself
- Guaranteed compatibility and timely updates for Gemini UI changes from the vendor
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a Chromium browser extension (manifest v3) using React for injected UI and TypeScript. Include content scripts that detect gemini.google.com, inject a sidebar and top bar controls, and observe chat DOM mutations. Implement: (1) folders and nested folder UI persisted via chrome.storage.sync (and optional Google Drive sync via OAuth using Google Drive API), (2) prompt library with // slash command quick insert, (3) chat export to TXT/MD/DOCX/PDF using client-side libraries (e.g., html2pdf, docx), (4) keyboard shortcuts configurable in an options page, (5) a client-side Prompt Optimizer module that applies rewrite templates and chains prompts sequentially, and (6) license activation UI storing a local license key. Out of scope: backend licensing server, paid storefront integration, and training models. Provide error handling for DOM mismatch and storage failures, unit tests for core modules, and end-to-end tests simulating gemini.google.com interactions.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
