## Overview

Memdex addresses a very practical daily annoyance: your best prompts, project background, and decisions are scattered across dozens of separate AI chats that each forget everything the moment you open a new thread. Instead of re-explaining your stack, your style, or your constraints every single time, Memdex builds a personal memory layer that travels with you between AI tools.

The extension auto-saves your conversations as you work, indexes them into a searchable local library, and then injects the relevant slices of context into whatever chat window you happen to be using. Because the memory store lives on your own device, the promise is that your private work discussions never get shipped off to a third-party server just to be remembered.

It is aimed at developers, writers, researchers, and power users who juggle several models at once and want continuity rather than cold starts. The trade-off is familiar for local-first tools: you get privacy and control, but the quality of retrieval depends on how consistently you use and curate the extension.

## Pricing & Plans

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.

## Key Features & Capabilities

- **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.

## Primary Use Cases

- **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.

## Strengths

- 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

## Limitations

- 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
