Tana is one of the most ambitious tools-for-thought apps, introducing "supertags" that turn any note into a structured data object with custom fields, views, and queries. For power users who want a personal database that doubles as a note-taking app, Tana is genuinely innovative. But the learning curve is one of the steepest in the productivity space, and the tool requires significant investment to use effectively. There is no audio recording, no lecture transcription, and no automatic study material generation. Notella serves the daily lecture capture workflow that Tana's structured approach does not address. If you enjoy building systems, Tana is fascinating. If you need to record lectures and study for exams, Notella handles that with zero configuration.
Tana introduces supertags — a concept that turns any bullet point into a structured data object. Tag a note as "#Meeting" and it gains fields for date, attendees, action items, and outcomes. Tag it as "#Book" and it gets fields for author, genre, and rating. These tagged objects can then be queried, filtered, and displayed in different views — like a database that lives inside your note-taking workflow.
Tana is currently in free beta, making it accessible for students willing to invest the learning time. The outliner-based editor is fast and keyboard-driven. Live search and AI integration help surface related content. For students who want to build a comprehensive system for managing courses, readings, assignments, and ideas, Tana offers a depth of customization that few tools match.
The downsides are real. Tana's learning curve rivals Roam Research and arguably exceeds it — understanding supertags, fields, views, and queries takes weeks of deliberate practice. The app requires a browser or desktop client. And critically for students in lectures, Tana is entirely text-based. No audio recording, no transcription, no automatic content generation. Every structured object must be manually created. During a fast-paced lecture, the overhead of correctly tagging and structuring notes in real-time is impractical for most students.
Notella requires no tags, fields, or schema design. Record a lecture, and the app generates AI transcription, educational summaries, flashcards, quizzes, and an AI chat feature. Study materials are ready within minutes of class ending. No configuration, no system design, no learning curve beyond pressing the record button.
The free tier is unrestricted. Premium costs $19.99 per month or $99.99 per year. Offline recording works in any classroom. Notella's philosophy is that students should spend time studying, not building productivity systems.
Tana and Notella represent opposite ends of the spectrum: maximum structure versus maximum automation.
Tana's supertag system is powerful for long-term knowledge management. A student who creates supertags for their courses can build views showing all concepts tagged as "#Concept" filtered by "#Economics," all readings tagged as "#Book" sorted by course, or all assignments tagged as "#Task" filtered by due date. Over a semester, this structured data becomes a queryable personal knowledge base that reveals patterns and connections.
But the investment to reach that point is enormous. Designing an effective supertag system requires understanding what types of information you will encounter, what fields matter for each type, and how you want to query it later. Most students do not know this upfront. The result is often weeks of redesigning and restructuring as you learn what works — time that could have been spent studying actual course content.
Notella has zero structural overhead. You record, the AI processes, and study materials appear. There is no schema to design, no tags to create, no views to configure. The simplicity is the feature. A student using Notella for the first time gets the same quality of output as someone who has used it all semester.
Tana's AI features help with text processing — summarizing, expanding, and querying written content. But they do not record lectures, transcribe audio, or generate flashcards from spoken content. Notella's AI is purpose-built for the lecture-to-study pipeline.
On pricing, Tana's free beta is a significant advantage for budget-conscious students. Notella's free tier is also unrestricted, and premium costs $19.99 per month. When Tana eventually launches its paid tier, the pricing comparison may shift.

Tana is a tool for system builders — students who enjoy designing structured workflows and want a personal database that grows more powerful over time. If you have the patience for the learning curve and the discipline to maintain a consistent tagging system, Tana can become an exceptionally powerful knowledge management tool.
Notella is for students who need study materials now. Record a lecture today, study from generated flashcards tonight. No system design required. For the vast majority of students — especially undergraduates juggling four or five courses with daily lectures — Notella's automatic approach turns every class into exam prep without asking anything in return.
