Best AI Note-Taking Apps Compared: Notion AI vs Granola vs Otter vs Mem

Overview

AI note-taking tools fall into two camps. Meeting assistants join your calls, transcribe them, and produce summaries. Knowledge tools help you capture, organise, and query everything else. The best choice depends on whether your bottleneck is being present in meetings or finding what you wrote six months ago.

These four cover the spectrum, and two of them — Notion AI and Mem — blur the line by adding meeting capture to an existing workspace.

Notion AI

Developer: Notion
Best known for: AI inside a full workspace
Pricing: Included with paid Notion plans; AI add-on pricing varies by region and plan.

Key Features

• AI writing, editing, and summarising across every page and database
• AI meeting notes that attach transcripts to project pages
• Enterprise search that answers questions across the workspace
• Databases and relations for structured knowledge
• Templates and automations for recurring workflows

Best For

• Teams already living in Notion
• Project documentation that mixes notes, specs, and tasks
• Organisations that want one tool for docs and AI

Limitations

• AI is only as good as your workspace hygiene
• Meeting capture is weaker than dedicated tools
• Cost scales with seats

Rating: ★★★★☆

Granola

Developer: Granola

Best For

• People in back-to-back meetings who type sparse notes
• Sensitive calls where a visible bot is unwelcome
• Founders, sales, and recruiters who live in conversations

Limitations

• Mac-first; other platforms lag
• No full knowledge base — it is a meeting tool
• Limited team analytics compared with enterprise suites

Rating: ★★★★★

Otter.ai

Developer: Otter.ai

Pricing: Free tier with limits; Pro around $17/month; business plans.

Key Features

Best For

• Teams that want a searchable record of every meeting

• Summaries can be generic without speaker context

Rating: ★★★★☆

Mem

Developer: Mem Labs
Best known for: Self-organising notes with AI search
Pricing: Free tier; Mem+ around $10/month.

Key Features

• Capture-first design — write now, organise later
• AI search that answers questions across your notes
• Automatic tagging and linking between related notes
• Email and calendar integration to capture commitments
• Chat with your knowledge base

Best For

• Individuals with messy, high-volume personal notes
• Researchers and writers connecting ideas over time

Limitations

• Smaller ecosystem and integrations than Notion
• AI organisation is good, not perfect — duplicates happen
• Team features are limited

Rating: ★★★★☆

How to Choose

• Your notes live in team docs: Notion AI.
• You want better notes from every meeting: Granola.
• You need a searchable transcript archive: Otter.ai.
• Your problem is personal recall: Mem.

Verdict

Granola is the standout for meeting-heavy knowledge workers, and Otter remains the safest pick for teams that need transcripts on record. Notion AI wins where notes are part of a larger workspace, and Mem is the best personal memory layer. Pick by where your notes go after the meeting, not by which transcript looks prettiest.
