AI teammate inside Notion: writing, workspace Q&A, agents, and meeting notes.

Notion AI is the assistant built into the Notion workspace, drafting and editing content, answering questions across your pages and connected apps, taking AI meeting notes, and running custom agents on triggers or schedules. Enterprise Search reaches into Slack, Google Drive, and GitHub, and the Notion Agent can complete multi-step tasks with workspace context.

Agentic meeting platform where AI agents do the work during the call.

Tana is a meeting workspace with native video calling, real-time transcription, and AI agents that act during the call — generating artifacts like PRs, tickets, and storyboards rather than only summarizing afterward. A persistent context graph remembers people, projects, and decisions across meetings, and AI changes go through a human-approval proposal step. It evolved from Tana's earlier supertag-based note app.

Networked, end-to-end-encrypted notes with a built-in AI assistant.

Reflect is a fast note-taking app that links ideas into a backlinked graph, syncs instantly across devices, and keeps notes end-to-end encrypted. Its AI assistant transcribes voice notes, drafts outlines, surfaces takeaways, and improves writing, with Google Calendar and Outlook integration plus web and Kindle clipping.

Visual, whiteboard-based knowledge base with AI for understanding what you read.

Heptabase is a visual note-taking and research tool that organizes ideas on infinite whiteboards built from linked cards, with a block editor, PDF annotation, web clipping, and bidirectional links. Its AI lets you ask questions and get cited answers across your PDFs, YouTube videos, notes, and journals, and an AI Tutor runs structured, personalized learning sessions. It runs on Mac, Windows, Linux, iOS, Android, and the web with offline support.
