Coffer

About

Coffer is the easiest way to save useful AI responses from ChatGPT, Claude, and Gemini into one searchable vault.

THE PROBLEM
You ask an AI a great question. You get a great answer. Later, you need that answer back - but it's buried 50 messages deep in some chat from last week. Sound familiar?

HOW COFFER FIXES IT
Hover any AI response → click "Stash" → done. The snippet is saved with its full Markdown formatting (code blocks, tables, lists, headings - all preserved). Find it later with full-text search across everything you've saved.

FEATURES
- One-click "Stash" button on every AI response
- Works across ChatGPT, Claude, and Gemini
- Searchable vault - find any snippet instantly
- Code blocks with language detection and syntax-aware rendering
- Tables, lists, and Markdown preserved when saved
- Full chats can be saved or exported as Markdown
- Folder organization for saved chats
- Local-first - your data never leaves your computer
- 100% free, no account required

PRIVACY-FIRST
Coffer has no server. We can't see your conversations because nothing is ever sent anywhere. All data lives in your browser via Chrome's local storage. The extension makes zero network requests of its own.

PERFECT FOR
- Developers saving code snippets from AI tools
- Researchers organizing AI-generated explanations
- Writers stashing useful drafts and ideas
- Anyone who uses AI tools daily and wants to remember what works

Coffer is built and maintained by a solo developer. Feedback, bug reports, and feature requests are all welcome - there's a contact email in the privacy policy.
