Tana

Overview

Tana is an AI-powered productivity workspace built on a knowledge graph. Instead of static pages and folders, everything you capture becomes a connected node you can tag, query, and view in multiple ways. Its Supertags system lets you add structured fields to any note, turning freeform text into searchable, filterable data. With built-in AI for transcription, meeting notes, chat, and voice capture, Tana helps knowledge workers collect, organize, and act on information in one place.

Key Features

Supertags: Tag any node with structured templates that add fields, views, and behaviors. Think of them as object-oriented labels that turn unstructured notes into queryable data.
Knowledge Graph Architecture: Everything is a connected node, not a static page. Information flows across your workspace through links, references, and live queries.
AI Meeting Notetaker: Captures meeting conversations without bots joining the call, then structures transcripts into action items, decisions, and follow-ups.
Live Search Widgets: Insert dynamic, real-time search results anywhere in your workspace. Results update automatically as matching nodes are created or changed.
AI Voice Chat & Capture: Record voice memos on mobile or have back-and-forth conversations with an AI assistant that understands your workspace context.
Offline Mode: Keep working without Wi-Fi. Changes sync automatically when you reconnect.
Multiple Views: Display the same data as lists, tables, kanban boards, or calendar items without duplicating anything.
Publish & Share: Turn parts of your workspace into clean, shareable views for clients, teammates, or the public with optional password protection.
Outline Editor: Tana uses a fast outline-based editor that lets you capture ideas immediately without setting up folders or databases first. Notes can start simple and gain structure over time.

Pros

AI That Understands Your Data: Unlike generic AI chat, Tana's AI works within your knowledge graph, so summaries and suggestions draw from your actual notes and context.
Extremely Flexible Structure: Build your system bottom-up. Start with simple bullets and add structure only when you need it. No rigid templates forced on you.
Strong Voice and Mobile Capture: Voice memos, meeting transcription, and Siri integration make it easy to get ideas into your system on the go.
Powerful Querying: Live search widgets let you pull information from anywhere in your graph based on tags, fields, and filters, displayed right where you need it.

Cons

Steep Learning Curve: Concepts like nodes, Supertags, and live queries take time to grasp. New users often struggle to set up their first workflows.
Limited Free Plan: The free tier caps you at 5 custom Supertags and 500 AI credits per month, which restricts access to what makes Tana unique.
AI Credits Are Metered On All Plans: Even paid users get a finite number of AI credits each month. There is no unlimited AI option, which feels restrictive given AI is a core feature.
Editor Formatting Gaps: The editor focuses on structured notes rather than rich document layouts.
Mobile App Still Catching Up: While Android and iOS apps now exist, they still lag behind the desktop experience in editing and navigation features.

Use Cases

Personal Knowledge Management: Capture ideas, highlights, and reading notes in daily entries. Supertags and live queries surface the right information when you need it, building a connected second brain over time.
Meeting Notes & Follow-Ups: Use the meeting notetaker to transcribe calls without adding a bot. Tana automatically extracts tasks, decisions, and follow-ups, linking them to projects and people in your workspace.
Task & Project Management: Create task Supertags with status fields, due dates, and project references. Use filtered views to build dashboards that show your next actions across all projects.
Research & Writing: Collect sources, tag them by topic, and use AI to summarize or extract key points. Live queries pull together all relevant material when you sit down to write.
Voice Capture and Idea Collection: Record voice memos or dictate ideas. Tana converts speech into structured notes that connect to your knowledge system.
Productivity Systems and Workflows: Build personal systems such as GTD or Zettelkasten using tags, dashboards, and live searches.
