Mem

What it does

Mem positions itself as an AI-native “second brain” rather than a traditional folder-and-tag notes app. Instead of asking users to manually organize where a note belongs, Mem uses AI to automatically surface related notes and lets people query their own notes conversationally through Mem Chat, similar to asking a question of a chatbot but grounded in what they’ve actually written. Mem 2.0, released in early 2026, focused on improving the speed and sync reliability that had been common complaints about the earlier version.

Because Mem is a smaller, venture-backed company rather than an established platform like Notion, it carries more uncertainty about long-term product direction — worth weighing against its lower setup overhead and affordable individual pricing.

Ideal users

• Individuals who want to capture notes quickly without manually organizing them into folders or tags
• People who prefer asking questions of their notes conversationally rather than searching by keyword
• Knowledge workers building a personal 'second brain' who don't want the setup overhead of a manual linking system like Obsidian

Who should avoid it

• You want full control over exactly how notes are structured and organized — Mem leans on automatic organization rather than manual folders
• You need a mature team-wide knowledge base with granular permissions — better served by Notion for larger teams
• You want a local-first, offline-capable tool — Mem is cloud-based
• You need deep bidirectional-linking and a visual graph view as your primary way of navigating notes — better served by Obsidian or Reflect

Key features

• Automatic organization — Mem surfaces and connects related notes without manual tagging or foldering
• Mem Chat: an AI chat interface that answers questions using your own notes as its knowledge base
• PDF ingestion so uploaded documents become part of your searchable knowledge
• Meeting notes capture
• Fast capture designed for quick note entry

Pricing

Free — $12/month (Pro plan)

Confirmed at get.mem.ai/pricing (mid-2026): Mem Free (25 notes, 25 Chat messages, and 25 PDF pages per month), Mem Pro at $12/month (unlimited notes, Chat, deep search, and PDF understanding, plus connected email, API access, meeting briefings, and AI model selection), and Mem Proactive at $99/month after a 7-day trial (adds the Mem Agent, which tracks decisions and open loops and proactively surfaces context before meetings and deadlines). The current public pricing page no longer lists a separate Teams plan.

Typical workflows

• Users jot down quick notes throughout the day without deciding where they belong, then rely on Mem's automatic organization to surface related notes later.
• Before a meeting or task, someone asks Mem Chat a question like 'what did we decide about X last month' instead of scrolling back through old notes.

Integrations

• Slack
• Google Calendar
• Gmail
• Google Drive and Google Sheets (via third-party automation platforms)
• Notion (via third-party automation platforms)
