LLMnesia vs Chat Memo: AI Chat Auto-Save Extension Comparison
Chat Memo and LLMnesia are close competitors: both are local-first Chrome extensions that auto-save and full-text search AI conversations across ChatGPT, Gemini, Claude, and more. Chat Memo is built around a card-style inbox you browse and export. LLMnesia is search-first, with jump-back links that return you to the original live conversation rather than a stored copy.

The real difference is design. Chat Memo is built around a card-style inbox you browse, manage, and export. LLMnesia is search-first, and its results jump you back to the original live conversation rather than a stored copy.

What Chat Memo does
Chat Memo (10,000+ users, 4.7 stars, featured on the Chrome Web Store) is a capable auto-save extension. It supports ChatGPT, Gemini, Claude, DeepSeek, Qwen, and others, and captures conversations automatically as you visit each platform, with a floating tab showing real-time save status. Its feature set includes:
- Automatic and manual save modes.
- Full-text search across saved conversations.
- A card-style conversation list with a link to the original chat page.
- One-click or selective data export.
- Data statistics summarising your total conversation count.
- Active maintenance with regular platform-compatibility updates.
It is a solid, actively developed tool, and because it is local-first with real search, it is a genuine alternative rather than a save-only competitor.
Where they differ
Both extensions save automatically and provide search, so the distinction is design priority and what "finding a conversation" means in practice.
- Chat Memo is a save-and-browse tool that also searches. Its interface centres on a conversation inbox you navigate, with export as a first-class feature. Jump-to-original is available but secondary to the stored view.
- LLMnesia is search-first. The core loop is: type a keyword, get results, click straight back to the original live conversation. There is no intermediate copy to browse.
The practical difference shows up at volume. With hundreds of indexed sessions across several platforms, a search-first design with direct jump-back tends to be faster than scanning a stored list, which is the workflow described in find old ChatGPT conversations.
A concrete example
You debugged a deployment script with Claude last month and want to resume that exact thread, not read a copy of it. In Chat Memo you would open the saved card and navigate to the original. In LLMnesia you search deploy script permission denied, click the result, and land in the live Claude conversation ready to continue. When the goal is to keep working in context, the search-first, jump-back path removes a step.
Can you use both together?
You can, though they overlap heavily, so most people pick one. If you already rely on Chat Memo's export and inbox, LLMnesia can sit alongside it purely for fast keyword retrieval. If you are choosing fresh, decide based on whether you primarily browse and export saved chats or primarily search and jump back to originals.
Choosing between them
Chat Memo is a good fit if:
- You want a well-rounded save tool with export and a browsable inbox.
- You like a visible floating status indicator while saving.
- You want coverage that includes Qwen and DeepSeek.
LLMnesia is a better fit if:
- Your main workflow is keyword search, then jump back to the conversation.
- You want retrieval optimised for speed over browsing.
- Returning to the live original session matters more than a stored copy.

Frequently asked
Does Chat Memo have full-text search?

The difference is design priority: Chat Memo surfaces a stored copy in a card inbox, while LLMnesia is search-first and links you back to the original live conversation.
Are both extensions local-first?
Yes. Both Chat Memo and LLMnesia store data locally in your browser rather than on a server. If keeping your AI history on-device matters to you, either tool fits that requirement.

Chat Memo supports ChatGPT, Gemini, Claude, DeepSeek, Qwen, and more. LLMnesia also covers the major platforms and 10+ in total. Check each extension's current release notes for the exact, up-to-date list.
Is LLMnesia a direct replacement for Chat Memo?
They are close. If your goal is to save and browse chats with export, both work well. If your goal is to type a keyword and jump straight back to the original conversation across many sessions, LLMnesia's search-first design is the tighter fit.
