Roam Research is the original networked-thought tool — freeform, outliner-based, and built around bi-directional linking at $15/month (or $165/year). Tana is a newer entrant that brings structured fields, supertags, and AI assistance to the same knowledge-graph concept; it is currently in free beta with paid pricing not yet announced. Roam has the larger established community, multiplayer graph support, and years of plugin development. Tana has better AI integration and a more database-like data model that suits users who want typed, queryable notes. If you live in Roam's freeform outliner and the community matters to you, there is no reason to switch; if you want structured knowledge with AI built in and can tolerate a newer product, Tana is worth the investment.

Note-taking and linking model
Roam's bi-directional linking and daily notes model has been refined over five years of active use by a demanding audience of researchers and writers. Every note links to every other note it references — forward and backward — and those links surface automatically in the sidebar. The outliner-first approach means that bullet hierarchies are the primary organizational unit; folding, unfolding, and referencing blocks within other notes is fast and ergonomic once it becomes habit. Tana also supports bi-directional linking, but its primary organizing metaphor is the supertag: a typed node with defined fields. This is more structured but also more front-loaded — you need to define your schemas before the tool pays dividends. For pure networked note-taking without upfront schema design, Roam's model is more immediately rewarding.
Structured data and database-style queries
Tana's supertag system is the feature that genuinely differentiates it. A supertag is like a class: you define fields (text, date, reference, checkbox, URL), and every node tagged with that supertag inherits those fields. You can then query across all nodes of a given type — show all projects tagged as active, or all books tagged as read in 2025 — using Tana's search and view commands. This is closer to a personal database than a note-taking tool. Roam has queries and filters, but they operate on block content and tags rather than typed fields. If you want to manage structured personal data — books, contacts, tasks, projects — Tana's model is significantly more powerful. Roam users who want this typically bolt on Datalog queries, which require learning a query language. In Tana, structured queries are the default.
AI integration and smart assistance
Tana has built AI assistance into the core product. You can trigger AI commands inline to summarize notes, generate content, extract structured data from freeform text, or fill in fields automatically. The integration feels native rather than bolted on — AI operates on the node and supertag structure, which means it can output properly typed data rather than raw text. Roam's AI story relies on community plugins; the most popular options add ChatGPT integration but it operates on raw text outside Roam's data model. For users who want AI to help process, summarize, and structure their knowledge — not just generate text — Tana's built-in AI is a substantive advantage. As both products evolve this gap may narrow, but as of mid-2026 Tana is the more AI-integrated of the two.
Community and plugin ecosystem
Roam has been publicly available since 2020 and has accumulated a substantial community: roamresearch.com forums, the Roam-Depot plugin registry, active Twitter/X communities, and thousands of hours of tutorials, templates, and workflows shared publicly. Plugins cover everything from Pomodoro timers to spaced repetition to citation management. That ecosystem means common problems have already been solved and published. Tana is newer; its community is active and enthusiastic but smaller, and its plugin story is still maturing. For users who rely on community knowledge — tutorials when stuck, workflows to borrow, plugins to extend behavior — Roam's larger ecosystem is a real practical advantage. Tana's community is growing fast and the developer team is more responsive, but if breadth of available resources matters today, Roam wins.
Collaboration and multiplayer
Roam supports multiplayer graphs: multiple users can work in the same graph simultaneously, with real-time updates. This makes Roam viable as a shared research or team knowledge base. Tana's collaboration features are limited in beta — you can share nodes and invite collaborators, but full multiplayer editing is not yet the default experience. For solo knowledge workers, this difference is irrelevant. For research teams, reading groups, or small teams who want a shared knowledge base, Roam's multiplayer support is currently more capable. As Tana matures toward general release with paid plans, collaboration features are likely to improve, but the present-day advantage belongs to Roam.
Pricing and long-term cost
Tana is free during its beta period, which is currently the best deal in this category. The risk is that once paid plans launch, pricing is unknown — it could land anywhere from freemium to premium. Roam at $15/month is a known quantity: $165/year for the annual plan is reasonable for a knowledge tool that is a core part of your workflow, and Roam has not raised prices significantly since launch. For anyone comparing today's cost, Tana is free and Roam is $15/month. For long-term planning, Roam's pricing stability is the safer bet. Evaluate Tana seriously now while you can use it at no cost, and re-assess when paid plans are announced before committing to a workflow that depends on it.
Pricing deep-dive
Tana
- Free during beta — no pricing announced yet for paid tiers
- Expect a freemium model with limits on AI usage and collaboration when paid plans launch
Roam Research
- Monthly: $15/month — full access, unlimited graphs
- Annual: $165/year — saves about $15 vs monthly billing
- No permanent free plan; 31-day trial available
Pricing verdict: Tana is free today, making it the obvious starting point for anyone willing to build on a product that may introduce paid pricing. Roam at $15/month or $165/year is a reasonable cost for a core daily-use tool with proven stability. Try Tana free now; switch to Roam if you need multiplayer, community plugins, or pricing certainty.
How to migrate from Tana to Roam Research
What real users say
Tana: Tana users are enthusiastic early adopters who praise the supertag data model and AI integration as genuinely new ideas in the PKM space. Common concerns are around beta stability, the uncertainty of future pricing, and the learning curve for understanding supertags versus traditional note-taking.
Roam Research: Roam users are loyal and often describe it as the only tool that matches how they think. Complaints focus on slow development pace, dated UI, and the steep initial learning curve. Some longtime users have migrated to Obsidian or Logseq citing cost or wanting local-first storage.

Final verdict
Choose Tana if...
- Choose Tana if you want structured, database-style knowledge management with typed fields and AI assistance built in from day one.
- Choose Tana if you are starting a knowledge system from scratch and want the most modern data model available at no current cost.
- Choose Tana if you manage typed personal data — books, projects, contacts — and want to query across it without learning Datalog.
Choose Roam Research if...
- Choose Roam Research if you prefer freeform outlining and bi-directional linking without upfront schema design.
- Choose Roam Research if community plugins, multiplayer graphs, and a mature ecosystem of shared workflows matter to your practice.
- Choose Roam Research if you want pricing stability and a proven tool that will not change its model when a beta ends.
Consider neither if: Consider neither if you want local-first storage with no cloud dependency — look at Obsidian or Logseq instead. Also consider neither if you need team collaboration beyond a small group; Notion or Confluence handle larger shared workspaces better than either tool.
