Chrome Extensions

Memdex is a Chrome extension that turns every AI conversation into reusable memory. It auto-captures your chats across ChatGPT, Claude, and Gemini, stores them encrypted on your laptop (IndexedDB, never uploaded), and underlines reusable context in your next prompt like Grammarly underlines typos. One click to inject when you need it just like grammarly. Free for your 10 most recent chats. Pro for unlimited.

Hey Product Hunt 👋 I'm Andrew. After spending most of last year jumping between ChatGPT, Claude, and Gemini, three things wore me down: 1. Every new chat starts at zero. I keep re-explaining the same project, the same constraints, the same voice. 2. My "memory" lives in someone else's cloud — locked to one model, invisible, unmovable. 3. The existing fixes are heavier than the problem: vector DBs, accounts, settings panels, prompts called /remember. So I built Memdex. Memdex is a browser extension that does three things, automatically: • Saves every chat on ChatGPT, Claude, Gemini, Perplexity, and Grok to encrypted files on your laptop. Never uploaded, never trained on. • Detects when something you already discussed is relevant to what you're typing now — like Grammarly, but for context. • Injects that memory into any AI tool with one click. No copy-paste. No re-explaining. The aha is the second tab: you open a fresh Claude window and it already knows your project, because last week's ChatGPT thread is on your disk and Memdex just pulled it in. It's local-first (memory never leaves your machine), cross-model (one memory, every tool), and zero-ritual (no /remember, no DB, no signup to start). Free tier auto-saves your 10 most recent chats; Pro is unlimited. 👉 Add to Chrome: https://chromewebstore.google.co... 👉 Site: https://memdex.ai What I'd love feedback on: - Where "detect" feels noisy vs. genuinely useful - Which tools you want next (Cursor, Windsurf, v0, Lovable are on the list) - Anything that makes you not believe "local-first" — I want to fix the perception, not just the reality Building in public from here — happy to answer anything in the thread. — Andrew

@xeasonchan I use Claude with a browser automation extension to handle long tasks. The problem is the context window fills up mid-task, and I have to star a new conversation — but the job isn't done yet. Every time I restart, I have to re-explaiin everything from scratch: what I was doing, how far I got, what's next.

Does Memdex handle this kind of scenario? Can it capture and resume that kind of task context, not just regular chat conversations?

I just woke up and opened Product Hunt to see what’s launching today. Memdex caught my eye so I went through the homepage, and the way you described the context detection flow felt clean. Great work! By the way I lose my best AI chats all the time. Scrolling through the history is a nightmare. So this idea... I like it. I have a question though. Since everything stays on my device, how does the matching actually work? Is it just looking for the same words, or does it understand the meaning behind them? Either way, cool product. Rooting for you.

@taimur_haider1 @taimur_haider1 Hey there, thank you for supporting us! Our product basically records every conversation locally. Then, for specific projects, we summarize and learn from those conversations — your context, preferences, and working style — and index them into project memory. Everything happens behind the scenes. When you prompt anywhere, Memdex can inject the relevant markdown file, just like Grammarly. The magic just happens in the background.

@xeasonchan Thank you for the detailed response. So it learns my style over time. That's smart. I will keep an eye on how this grows. One more thing... do you have a LinkedIn page or Twitter for Memdex?
