ChatStash 作成者: WhatPulse

** Your AI conversations shouldn't live on someone else's server. **

ChatStash automatically backs up your conversations from ChatGPT, Claude, and Gemini to your browser's local storage. Every question you ask, every answer you get, stays on your device where you control it.

Key features

Automatic backups - Conversations save as you chat. No manual exports or extra steps.

Local storage only - Everything stays on your device. No cloud sync, no external servers, no data leaving your browser.

Works with all major AI platforms - ChatGPT (including GPT-4), Claude, and Google Gemini.

Full-text search - Find any conversation by keyword, date, or platform.

Preserves formatting - Keeps markdown, code blocks, lists, and generated images intact.

Export when you need it - Export individual chats or your entire archive to JSON.

Why local storage matters

AI platforms can delete conversations, impose storage limits, or change their data retention policies without warning. When your account has issues or a service goes down, you lose access to everything.

ChatStash gives you ownership. Your conversations live on your device, backed up automatically, accessible anytime. No accounts to create, no permissions beyond what's needed, no tracking.

Who it's for

Developers who reference code solutions from AI assistants. Researchers building knowledge bases from AI conversations. Writers keeping drafts and ideas. Students saving study materials. Anyone who uses AI tools regularly and wants to keep what they create.

How it works

Install ChatStash, then use ChatGPT, Claude, or Gemini normally. The extension monitors your chats and saves them automatically to your browser's local database. Open the sidebar panel anytime to browse, search, or export your conversations.

What's not captured

ChatStash backs up standard chat conversations. Features that open in separate interfaces aren't captured, including ChatGPT Canvas, Claude Artifacts, and similar tools that create documents outside the main chat.
