Mem, Joute's review

The essentials

• Notes app with automatic AI organization (no manual folders)
• Free plan, Pro at $14.99/month
• AI that links and organizes notes automatically, semantic search
• Competitor to Obsidian and Notion for personal knowledge base management

What is Mem

Mem is a notes app where AI handles organization for you. Rather than manually filing your notes in folders (like Notion or Obsidian), you write, and Mem automatically links related notes, identifies themes, and lets you find information via natural semantic search ("the notes about my Paris project from last week"). The vision is to create a "second memory" that organizes itself without manual friction. The execution is interesting but not always as smooth as promised.

Strengths

Automatic organization without folders

The absence of manual taxonomy reduces note-taking friction. You write, Mem organizes. Ideal for people who always abandon their folder systems.

Natural semantic search

Finding notes by asking a natural question rather than searching for an exact keyword. "What I noted about the meeting with Pierre in March" works.

AI that links related notes

Mem identifies connections between your notes and suggests them. Useful for knowledge workers with many disparate notes.

Limits

Contested value proposition

Notion AI and Obsidian with plugins do some of the same work. Mem's pure differentiation is narrower than its positioning.

Dependency on the Mem ecosystem

All your notes are in Mem. If the startup pivots or closes, export and migration are a risk.

Pricing

Free plan with limits. Pro at $14.99/month. Check mem.ai/pricing.

Alternatives

Mem = AI notes with automatic organization. Alternative Notion AI (notion.so) = $10/month, more complete but more setup friction. Alternative Obsidian (obsidian.md) = free, local, more control, AI plugins.

Verdict

Mem is relevant for people who take a lot of notes but can never organize them. Automatic organization eliminates the main friction. For someone already using Notion or Obsidian satisfactorily, migration isn't justified.
