Notion AI vs Obsidian: pricing, features and which to choose

Notion AI is Notion Labs’ embedded assistant for workspaces combining notes, documents, tasks, and databases. Launched in 2022 and generally available in 2023, it now drafts and edits pages, answers workspace questions, researches topics, transcribes meetings, searches connected apps, generates formulas, autofills databases, and runs scheduled Custom Agents. Auto routes requests among available models, while named options include Opus 5.5, Astra, Fable, Claude Sonnet 4, GPT-5, GPT-4.1, and Claude 3.7 Sonnet, with availability varying by plan. Free costs $0 and Plus $10 per member monthly, both offering limited AI trials; Business is $20 with AI included, while Enterprise is custom priced. Compared with ChatGPT and Claude, Notion offers deeper page context; Otter.ai remains stronger for dedicated transcription. It suits teams already organized in Notion, but users should verify outputs and monitor credit limits.

A typical request starts in a Notion page, database, or chat, where users can ask Notion AI to draft, summarize, rewrite, translate, generate formulas, create databases, or answer workspace questions. Notion Agent extends this workflow by creating and editing pages and databases while using permitted workspace, connected-app, and web context for multi-step tasks. Research Mode builds detailed reports from workspace and web information, while AI Meeting Notes transcribes conversations, summarizes key points, and extracts follow-ups. Enterprise Search combines Notion with Slack, Google Drive, and GitHub, returning answers with citations. Custom Agents automate recurring work through schedules or triggers, and AI blocks insert generated content into ordinary pages. Database Autofill populates properties, making routine classification and enrichment faster without leaving the workspace.

Notion AI is best understood as an AI layer inside a team workspace rather than a purely standalone chatbot. Its value comes from combining page-aware answers, writing assistance, database autofill, meeting transcription, research reports, and agents that can create or edit Notion content while using connected-app and web context. Auto routes tasks among available models, while users may access named options such as Claude Sonnet 4, GPT-5, GPT-4.1, Opus 5.5, and Astra, depending on plan and availability. Free and Plus include limited trials; Business costs $20 per member monthly, and Enterprise is custom priced, with credits, limits, and provider-retention policies requiring attention. ChatGPT and Claude are stronger general assistants, while Otter.ai focuses more narrowly on transcription. Notion AI suits knowledge-centered teams that accept usage controls and fact-checking.

Obsidian is a desktop and mobile note-taking app made by Dynalist Inc., a small independent company founded by Shida Li and Erica Xu, and first released in 2020. It runs on Windows, macOS, Linux, iOS and Android. Notes live in a vault, which is a folder of plain Markdown files on your device, so they open in any text editor and outlast the app. Obsidian takes no venture capital and calls itself 100 percent user-supported. In February 2025 it made the commercial license optional, and the company says people at more than 10,000 organizations, including Amazon and Google, use it for work. Version 1.15 shipped in October 2026.

Writing happens in a Markdown editor with live preview. Typing double brackets links one note to another, and every note shows its backlinks, so ideas connect without a fixed folder hierarchy. The graph view draws those links as a network. Canvas gives an infinite board for arranging notes, images and web pages, and Bases, a core plugin added in 2025, turns notes with properties into sortable tables, cards or maps that work like a lightweight database. Daily notes, templates and tags cover journaling and task capture. The 1.15 mobile release added voice Quick Capture with live transcription on iOS 26, and PDF export on mobile.

Obsidian's flexibility is also its main drawback. A new vault is a blank editor, and building a useful system takes time and plugin choices. Real-time collaboration is limited compared with Notion, Microsoft Loop or Google Docs, and community plugins vary in quality and security. Notion suits teams that want shared databases and built-in AI. Logseq, which is open source, offers an outliner model with similar local files. Anytype offers local-first, encrypted notes with object-based structure. Pick Obsidian if you want notes that remain usable files in 20 years and are willing to add AI yourself; pick Notion for team wikis.
