## 總覽

Memdex is a browser extension that automatically captures your AI chat history across ChatGPT, Claude, and Gemini, stores it locally, and lets you re-inject past context into any new conversation.

## 價格與方案

Freemium. The extension is installable and usable without payment, with a free tier covering core saving and recall. A paid tier is offered for heavier usage; check the official site for current limits and prices since exact figures are not published on the homepage.

## 關鍵功能與能力

- **Automatic conversation capture:** Your chats in ChatGPT, Claude, Gemini and other AI tools are saved in the background without you having to copy-paste anything.
- **Local-first storage:** Memories are kept on your own device, so sensitive project context stays under your control rather than in a vendor cloud.
- **Context injection:** Pull a previous conversation, snippet, or project brief straight into a new chat so the model starts with your background already loaded.
- **Searchable memory library:** Browse and search everything you have saved to find that one prompt or decision you half-remember.
- **Multi-tool portability:** Move context between different AI assistants, so switching models doesn't mean starting from zero.

## 主要使用情境

- **Carry your codebase context between models (Software developer):** Store your architecture notes, conventions, and past debugging threads so any new AI chat immediately understands your project.
- **Reuse your voice and briefs (Content writer):** Keep brand guidelines, tone notes, and past outlines on hand and inject them so every drafting session sounds consistent.
- **Build a searchable research log (Researcher):** Let the extension archive your literature questions and answers, then recall them when writing up findings.
- **Keep AI memory off the cloud (Privacy-conscious power user):** Maintain a personal memory bank locally instead of enabling vendor-side memory features you don't fully control.

## 優勢

- Saves AI conversations automatically so you never lose a good prompt
- Local storage model appeals to privacy-conscious users
- Works across several major AI assistants instead of locking you into one
- Injected context cuts down on repetitive re-explaining

## 限制

- Retrieval quality depends on consistent curation of your memory bank
- Requires installing and trusting a browser extension with your chat data
- Exact free-tier limits and paid pricing are not clearly published on the homepage
