Where Asksia ends

3 things Asksia wasn't built for

Asksia shines at homework Q&A. These are the gaps when you try to use it for full-course study.

Gap 01

No whole-course memory

““Explain Q4 of problem set 3.” — the answer is correct, but in isolation.”

Truth: It doesn't know what lectures 1–8 said, or which PDF defined the term.

ThetaWave keeps every lecture, slide and reading in one searchable workspace and cites across them.

Gap 02

Per-prompt study cards

“Flashcards from a single question miss everything around them.”

Truth: Your real exam scope spans 12 weeks of class, not one prompt.

ThetaWave builds flashcards and quizzes from your entire course library at once.

Gap 03

Lecture-day handoff

“You leave class with a recording, then re-paste pieces into a chat to ask follow-ups.”

Truth: Capture, notes and Q&A live in separate places, so context is lost.

ThetaWave records, transcribes and turns the lecture into structured notes in one flow.

FAQ

Questions, answered

For most STEM students — yes. Asksia is excellent at single-problem help, but a real course covers 12+ weeks of lectures, slides and readings. ThetaWave indexes the whole course and answers questions grounded across every source, while also generating notes, flashcards and quizzes from the same library.

Yes. Keep Asksia for one-off problem sets, and use ThetaWave as the place where your course materials, structured notes and exam-prep flashcards actually live.

Yes — ThetaWave's AI Assistant works on whatever you've uploaded. Drop in the problem set plus the related lecture or chapter PDF, and you get an answer grounded in the source material your professor actually taught.

Lecture capture is a first-class workflow in ThetaWave. Hit Record, transcribe in real time, and the lecture becomes the same kind of source as a PDF — searchable, citable, and ready to generate flashcards and quizzes from.

Asksia uses a free tier plus paid options for heavier usage. ThetaWave has a free plan; Pro starts at about $0.33/day on the annual plan ($118.80/year), with weekly and quarterly options for exam weeks. Verified students get 30% off the first billing cycle.
