CogniMemo helps your AI remember. It adds long-term memory to ChatGPT and other AI tools. You can type @cogni in any chat to search your saved notes, past chats, and content. It works with ChatGPT, Claude, Gemini, and DeepSeek. You can save posts from X/Twitter, archive your AI conversations, and use a floating assistant on any website to explain or write using your own knowledge. Everything stays organized in one fast, searchable place—and your data stays under your control.
The @cogni trigger is an elegant approach to memory recall - avoids switching context between tools. Curious how CogniMemo handles semantic search when the saved content is in different languages, since many developers work across multilingual docs and codebases.
“AI that actually remembers” sounds simple, but it’s surprisingly hard to get right. Curious to see where this goes.
Congrats on the launch.
Incredible, I love this simple UX, less is more and nothing else is needed
Wondering how you’re thinking about memory hygiene long-term, like how do users avoid outdated or conflicting memories being pulled back into chats?
Hey Product Hunt 👋 I’m Sami, founder of Cognimemo.
We built Cogniextension because AI tools forget everything the moment your chat ends — and humans shouldn’t have to repeat themselves.
Cogniextension lets you save, recall, and reuse context across tools, tabs, and conversations.
What it does (plain English)
🧠 Capture important info while you work (notes, decisions, context)
🔍 Retrieve the right memory when you ask — not a long chat history
📌 Pin what matters and expand it when you need deep context
🤖 Designed for AI workflows, not just note-taking
This isn’t another notes app. It’s context infrastructure for people using AI every day.
Who it’s for
Builders & developers
Researchers & writers
Anyone tired of re-explaining things to AI
Why we built it
We noticed something broken:
AI is powerful, but it has no memory — and humans pay the cost.
Cogniextension is our first step toward fixing that.
What we’d love from you
Try it and break it
Tell us where it actually helps (or doesn’t)
Feature requests > compliments 🙂
We’re shipping fast and listening closely.
Thanks for checking it out — excited to hear what you think! 🙌
Hey Product Hunt 👋
I’m Volkan Çetin, Co-Founder of CogniMemo.
We built CogniMemo Extension because AI forgetting everything felt broken.
Every chat resets
Every tool is isolated
Every insight gets lost
We wanted AI to actually remember — across tools, chats, and the web.
What CogniMemo Extension does:
Adds long-term memory to your AI
Lets you search your own knowledge by typing @cogni in any chat
Syncs your X (Twitter) content and AI conversations into one memory
Gives you a floating AI copilot you can use on any website
Works as one browser extension
Acts as a single memory layer you can use with any LLM
One extension.
One memory layer.
Any AI model.
We’re excited to finally share this with you.
Would love your feedback and questions 🚀
