LLMnesia vs Chat Memo — AI Chat Auto-Save Extension Comparison

What Chat Memo actually does

Chat Memo (10,000+ users, 4.7★, Featured on Chrome Web Store) is a capable auto-save extension. It supports ChatGPT, Gemini, Claude, DeepSeek, Qwen, and others. When you visit any of these platforms, Chat Memo captures conversations automatically. A floating tab shows real-time save status.

Its feature set includes:

• Automatic and manual save modes
• Full-text search across saved conversations
• Card-style conversation list with jump to original chat page
• Data export — one-click or selective export
• Data statistics — summary of total conversation count
• Active maintenance with regular platform-compatibility updates

Chat Memo is a solid choice and is being actively developed.

Where they differ

Both extensions save conversations automatically and provide search. The distinctions are in design priority and what "finding a conversation" means:

Chat Memo is a save-and-browse tool that also has search. Its interface is built around a conversation list you navigate. Jump-to-original is available but secondary to the stored view.

LLMnesia is search-first. The core workflow is: type a keyword → get results with direct links back to the original live conversation. There is no intermediate copy to browse.

The practical difference appears at volume. When you have hundreds of indexed sessions across multiple platforms, a search-first design with direct jump-back tends to be faster than browsing a stored list.

Choosing between them

Chat Memo is a good fit if:

• You want a well-rounded save tool with export and browse capabilities.
• You want a visible floating status indicator while saving.
• You need strong platform coverage including Qwen and DeepSeek.

LLMnesia is a better fit if:

• Your primary workflow is keyword search → jump back to conversation.
• You want retrieval optimised for speed over browsing.
• The stored copy matters less than getting back to the live original session.
