Turn YouTube courses into practice you can build on

Course study workspace

• Create a searchable transcript with time points so claims, quotes, and sections stay tied to the video.
• Generate and edit timestamped video summaries, then jump back to the relevant moment from the research workspace.
• Select transcribed lessons from a project and ask AI Tutor to create an interactive online quiz across those lessons.
• Use answer history in later comprehensive quizzes: revisit missed, unanswered, and partially correct questions, and practice variants of questions answered correctly.
• Publish a shareable quiz page that others can try without installing the extension or signing in.

More than a video summary

Use transcripts and summaries to organize a course, ask AI Tutor questions about the material, and test your understanding through practice. Timestamp references help you return to the relevant explanation; an advanced variant may apply the same concept in a new situation rather than repeat the video example.

How Token works

Customers buy prepaid Token. One shared Token balance covers supported research operations. Usage-based AI requests consume the combined input and output Token total reported by the upstream model, while fixed-charge operations disclose their charge before confirmation. The current package and balance are shown in the user center.

Content and responsibility

Oxally is delivered online as SaaS software. You are responsible for having the right to submit a video, transcript, link, or other material for processing, and for reviewing AI-generated outputs before relying on them.
