Founded in 2021 and headquartered in Oslo, Norway, Tana has raised approximately $7 million and attracted a growing community of power users in product management, operations, and knowledge-intensive professional workflows who find traditional note-taking and wiki tools too unstructured for managing complex operations.\n\nTana's core innovation is a node-based information architecture where every piece of content — notes, tasks, contacts, documents — is a structured object with properties that can be linked, queried, and referenced across the workspace. AI capabilities within Tana allow users to generate content, extract structure from unstructured notes, run semantic searches, and build AI-powered workflows that process and transform information automatically. Teams use Tana for operational runbooks, franchise and operations documentation, client management, and structured knowledge capture that benefits from both the flexibility of text and the queryability of databases.\n\nTana competes with Notion, Obsidian, Roam Research, and other knowledge management platforms in the productivity and second-brain tool market. Its semantic graph architecture and AI integration position it for users who have outgrown simpler tools, while its relative novelty means it serves a more technically sophisticated early-adopter audience currently. The platform's potential applicability to franchise operations documentation and structured operational workflows has attracted business users seeking alternatives to rigid database tools. ## Frequently Asked Questions ### What makes Tana different from Notion or other note-taking tools? Tana uses a semantic graph model where every piece of information is a structured object with properties and bidirectional links, enabling users to build interconnected operational databases, workflows, and knowledge graphs with more structure than Notion's block model while remaining as flexible as a note-taking tool for unstructured capture. ### What AI capabilities does Tana include? Tana includes AI features for generating content within the workspace, extracting structured information from unstructured notes, semantic search across the knowledge graph, and AI-powered commands that can process and transform nodes automatically — enabling workflows that move beyond manual knowledge capture to intelligent information structuring and retrieval. ### Who uses Tana for operational workflows? Tana is used by product managers, operators, and knowledge workers managing complex interconnected information such as product roadmaps, operational runbooks, client portfolios, and team wikis, as well as teams seeking to build structured operational documentation and workflows that benefit from Tana's semantic linking and AI query capabilities. ### What is Tana and how does it work? Tana is an AI-powered knowledge management platform that structures information using a semantic graph model. Every piece of information is a structured node with properties and bidirectional links — allowing teams to build interconnected knowledge bases, workflows, and operational databases that are more structured than Notion while remaining flexible for unstructured capture. ### How does Tana handle team collaboration? Tana supports collaborative workspaces where multiple team members can work simultaneously on interconnected knowledge graphs, with real-time sync, comments, and role-based access. Teams build shared operational databases where information entered by one person is automatically connected to relevant nodes maintained by others. ### What is the vertical field in Tana's database - 'Vertical SaaS — Franchise Management Tech'? Tana is categorized there because of its operational database capabilities that can support complex franchise-like organizational knowledge management needs — but Tana is primarily a knowledge management and collaborative workspace platform used broadly across product management, operations, and research workflows. ### Is Tana suitable for individual use or only teams? Tana supports both individual power users (researchers, writers, consultants building personal knowledge graphs) and team workspaces. It gained initial traction among individual knowledge workers who prefer its semantic structure over Notion's block model before expanding to team collaboration use cases. ### How is Tana priced? Tana offers a free tier for individual use with limited workspace size and AI features, and paid team plans with more nodes, AI credits, collaboration features, and admin controls. Pricing is designed to be accessible for individual users while scaling to team plan pricing for organizational deployments. ### What is Tana? Tana is an AI-powered note-taking and knowledge management tool for professionals and knowledge workers, providing a flexible workspace that combines notes, tasks, databases, and AI assistance in a single tool inspired by Roam Research and Notion but with deeper AI integration. ### What makes Tana different from Notion or Obsidian? Tana uses a supertag system that turns any note element into a structured data type with AI-powered properties, enabling users to build personal knowledge graphs and databases that are simultaneously free-form and structured — a different paradigm from page-based Notion or link-based Obsidian. ### Who uses Tana? Tana's power users are knowledge workers, researchers, writers, and executives who manage complex information workflows and want an AI-native tool that grows smarter about their work and thinking patterns over time. ### How does Tana's AI work? Tana's AI can process supertag fields, generate content based on note context, extract structured data from unstructured text, and help users query their knowledge base using natural language — making the knowledge graph active rather than a passive archive. ### How much has Tana raised? Tana has raised approximately $5M from investors including Northzone and Notion's CEO Ivan Zhao, building its AI-native knowledge management tool with a strong community of power users in the personal knowledge management space. ### What does Tana do as a software platform? Tana is an AI-powered note-taking and knowledge management platform that applies semantic AI to personal and team knowledge management. It enables users to capture notes, tasks, and information in a flexible structure and uses AI to surface connections, surface relevant context, and make knowledge more actionable compared to traditional note-taking apps. ### What makes Tana different from note-taking tools like Notion or Roam Research? Tana differentiates through its semantic AI capabilities—the platform understands the meaning of notes and can create typed fields, suggest connections, and enable structured data capture alongside free-form notes. Unlike Notion (database-first) or Roam Research (graph-based backlinks), Tana combines flexible note capture with AI-assisted structure that emerges from the content rather than requiring upfront schema definition. ### Who is Tana designed for? Tana targets knowledge workers—researchers, founders, product managers, writers, and other professionals who manage large amounts of information and find traditional note-taking tools insufficient for capturing and retrieving complex knowledge. The platform is particularly popular among power users in the personal knowledge management (PKM) community who use tools like Obsidian, Roam, or Notion. ### What AI features does Tana include? Tana's AI features include Tana AI for generating text, summarizing nodes, completing structured fields, and surfacing related content from across the user's knowledge base. The AI can also be used to process and categorize notes, suggest related information during capture, and generate output documents from accumulated notes—reducing the effort of synthesizing distributed knowledge. ### What is Tana's pricing and availability? Tana has been in an invite-only or limited beta phase during its early development, offering free access to invited users while the product matures. Paid plans are expected for individuals and teams at competitive pricing with other productivity tools. The company is based in Norway and has focused on building a strong early adopter community among productivity enthusiasts before broader commercial launch. ## Tags saas, b2b, smb, platform, ai-powered, productivity, collaboration, europe, startup, no-code, enterprise --- *Data from geo.sig.ai Brand Intelligence Database.
