How to search your ChatGPT, Claude and Gemini history in one place
Connect your accounts once, then search seven AI platforms from one box. Operators, filters and the Echo assistant, with examples.

Echoes reads your chat history from ChatGPT, Claude, Gemini, Grok, DeepSeek, Perplexity and Google AI Studio and puts it in one list. You search that list instead of seven sites. The free Lite plan includes 20 searches a month.
1. Install and connect
Add Echoes from the Chrome Web Store, then sign in to each AI in the same browser. Echoes shows an Account Detected card; click Add Account and it downloads that account's chat history. It uses the session you already have and never asks for your AI passwords. If you have two ChatGPT accounts, add both and Echoes lists each one on its own. The connect accounts tutorial walks through it with screenshots.
2. Search with plain words
Type a few words and press Enter. Echoes searches the text of each message, not only the titles, and shows how many times your words appear in each chat. It also matches word forms, so budget finds "budgets" and "budgeting".
3. Narrow it down
"customer churn"finds that exact phrase.invoice OR receiptfinds either word.python NOT djangodrops chats that mention Django.service:claudesearches Claude only.label:workorproject:"Q3 plan"searches one label or project.date:last30dayslimits to the past month.
You can combine them: "churn model" service:chatgpt date:thismonth.
4. Or ask Echo
On Plus and Lifetime you can ask Echo in plain English: "find the chat where I planned the Q3 budget with Claude". Echo turns that into a search with the right filters and returns links that open each chat on its own platform. Plus and Lifetime include 50 Echo questions a month.
5. Keep what you find
Star a chat as a favorite, or give it a label. Labels can nest (Clients > Acme > Contracts) and hold chats from any platform. Next time, label:Acme returns the lot.
Where your data lives
Echoes processes and stores your conversations in your browser. Your chat text does not go to Echoes servers for search. The your data tutorial explains what syncs between devices and what stays local.
