SILENTLY REMEMBERING

Never explain
yourself twice.

Echo silently saves your ChatGPT and Gemini conversations as searchable memories, then recalls the right context back into your chat with one click — before you have to ask twice.

01 WHY ECHO
Built for people who live in ChatGPT and Gemini
i.
Silent capture.
Every message you send and receive in ChatGPT or Gemini is saved locally as a searchable memory. No copy-paste, no exporting.
ii.
One-click recall.
When you need old context, Echo finds the right past conversation and injects it straight into your prompt.
iii.
Semantic search.
Memories are embedded with OpenAI so recall finds what you meant, not just what you typed.
iv.
Your data stays yours.
Everything lives in IndexedDB on your device. Only the text sent for embedding ever leaves your machine.
02 CONNECT YOUR OPENAI KEY
Stored locally · sent only to api.openai.com

Recall needs an embedding to work.

Echo uses OpenAI's text-embedding-3-large to turn your saved conversations into searchable memories. Your key is entered and stored inside the extension itself — never on this site — so it's saved in your browser's local storage and never leaves your device except in calls to OpenAI.
