Mem

This gives Claude persistent memory across conversations using a local SQLite database. It's straightforward: search for what you've stored, add new memories with tags, delete what you don't need. The full-text search means you can actually find things later, and you can attach images to memories. The real value is when you're working on a project over multiple sessions and don't want to keep re-explaining preferences, architectural decisions, or deployment commands. It pipes well with other tools and outputs JSON when you need it. Think of it as a notebook that Claude can read and write to, stored in `~/.mem/mem.db` on your machine.

mem — Agent Memory Store

A CLI tool for storing and retrieving memories with full-text search. Data is stored locally in ~/.mem/mem.db.

When to Use

Remember user preferences, project decisions, important facts
Store code snippets, commands, configurations for later recall
Search your knowledge base before asking the user for information you may have stored
Attach images (screenshots, diagrams) to memories

Commands

Three operators: (none) = recall, + = remember, - = forget.

Recall (search, list, get)

mem                             # list recent memories
mem "deploy"                    # full-text search
mem "database" --tag db         # search filtered by tag
mem 7sjtNVyZrNIa                # get full content by ID
mem --tag prefs                 # list filtered by tag
mem "api" --limit 5 --json     # limit results, JSON output
mem --full                      # show full content for all
