The 8 Best AI Note-Taking Apps in 2026

Notes are only useful if you can find and use them later — and that's exactly where AI helps. AI note-taking apps capture your thoughts and meetings, organize them, connect ideas, and let you ask questions across everything you've saved. Here are the 8 best in 2026, split by what you actually want to do.

Two kinds of AI note apps

There are knowledge apps (write, organize and query your own notes — a 'second brain') and meeting notetakers (record and summarize calls automatically). Pick based on whether you're capturing your own thinking or your conversations — many people use one of each.

1. Notion — best all-in-one with AI

Notion combines docs, wikis and databases with built-in AI that can summarize, write and answer questions across your workspace. For a flexible knowledge base that does far more than notes, it's the all-in-one leader — see our Notion vs Obsidian guide.

2. Reflect — best AI second brain

Reflect is a fast, networked note app with backlinks, end-to-end encryption and built-in AI that helps you write and connect ideas. For a private, thinking-focused second brain, it's a standout — see our Reflect review.

3. Mem — best AI-first, self-organizing notes

Mem is built around AI: it organizes your notes for you and surfaces related ones automatically, so you spend less time filing and more time capturing. For people who hate manual organization, its AI-first approach is refreshing.

4. Obsidian — best private, extensible knowledge base

Obsidian stores notes as local Markdown files you fully own, with a huge plugin ecosystem (including AI plugins) and a powerful graph view. For a private, endlessly customizable second brain, nothing beats it — and it's free for personal use.

5. tl;dv — best AI notetaker for meetings

tl;dv records, transcribes and summarizes your Zoom, Meet and Teams calls automatically, with a generous free plan. For turning meetings into searchable notes and action items, it's a top pick — see our best AI meeting notetakers guide.

6. Otter.ai — best established meeting notes

Otter is a mature AI notetaker with live transcription, summaries and an AI chat you can question about your meetings. A reliable, well-supported choice for meeting-heavy work.

7. Supernotes — best card-based collaborative notes

Supernotes organizes knowledge into linked 'notecards' with AI help and instant sharing. For fast, connected, collaborative note-taking, it's a delightful, focused option — see our Supernotes review.

8. NotebookLM — best for querying your sources

Google's NotebookLM lets you upload documents and notes and then ask questions grounded in them, with citations — even generating audio overviews. For turning a pile of sources into an AI you can interrogate, it's genuinely novel and free.
