Tana

Tana Inc. builds two products that share the Tana brand: Tana, an agentic meeting platform where AI agents do real work during native video calls and land decisions, tasks, and drafts in a persistent context graph; and Tana Outliner, a knowledge-management tool built on an infinite outliner with supertags and nodes. Tana exposes two public HTTP APIs — the Tana Input API for programmatically adding nodes, fields, and supertags to an Outliner workspace graph (workspace-scoped bearer-token auth), and a public agent-native Documentation API for searching and reading Tana docs as clean markdown. Backed by Lightspeed Venture Partners and Northzone.

Tana publishes 1 API on the APIs.io network: AddToNodeV2 API. Tagged areas include Company, Note Taking, Knowledge-Management, Productivity, and Artificial Intelligence.

Tana’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, authentication, and 24 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/tana: open an issue to ask a question, or submit a pull request to add artifacts.
