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 contract indexed on the APIs.io network: AddToNodeV2 API. Tagged areas include Company, Note Taking, Knowledge Management, Productivity, and Artificial Intelligence.

The Tana catalog on APIs.io includes 1 Spectral governance ruleset.

Tana’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, authentication, and 31 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Atlassian Marketplace (builders on Jira, Confluence, Bitbucket)	covered	26.8 (thin)	-	-
Raycast Store Extensions (first-party publishers + community-wrapped products)	covered	26.8 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
