Competitive Landscape

Who Tana competes with, and how they differ.

Notion6.6/10

Notion is a much broader all-in-one docs/wiki/database workspace with a far larger installed base and freemium-led growth; Tana is narrower and AI-native, organizing everything through a single knowledge graph with typed supertags and built-in AI agents rather than Notion's page-and-block model.

O

Obsidian

Obsidian is a local-first, markdown-file-based PKM tool with a large third-party plugin ecosystem and a free core license (no required subscription); Tana is a cloud-native SaaS built around structured supertags and AI capture rather than Obsidian's freeform linked-notes vault.

Mem.ai7.2/10

Mem.ai (Mem Technologies) auto-organizes unstructured notes with AI and centers on an AI chat interface over your notes, with no manual tagging required; Tana instead has users explicitly model information with supertags and fields, trading some automation for structured, queryable data.

Coda7.9/10

Coda blends documents with app-like building blocks — tables, buttons, automations — aimed at team workflows and internal tools; Tana centers on a single unified knowledge graph with AI-driven capture across notes, tasks and meetings rather than Coda's doc-as-app model.

R

Roam Research

Roam Research popularized bidirectional-linking, block-based outlining for "networked thought" and predates Tana's supertag model; it lacks Tana's built-in AI agents and typed-field system, and much of its early community has since moved to newer AI-native tools.
