Learning rarely arrives in one format. A lecture might be a video, a reading might be a PDF, and tomorrow's review material might be a PowerPoint deck.
Abstruck's Workspace now adapts to each of those sources while keeping the same study flow around them.
One Workspace, Different Sources
Uploaded videos now play securely inside a responsive video viewer. Playback remains connected to the transcript, so clicking a timestamp seeks the video and the active passage follows along without pulling the page away from what you are doing.
Audio keeps its focused custom player and synchronized transcript experience.
PDF and PowerPoint files take a different path. They do not need transcription. Abstruck reads their document structure, preserves page boundaries, and turns the extracted content into material that the study tools can cite.
Keep the Source in View
For PDFs, the original document stays visible above the Workspace tabs while chat remains beside it on larger screens. You can read the source, ask a question, and continue into summaries, flashcards, notes, or exports without moving between separate tools.
On smaller screens, the source and chat stack cleanly so the Workspace remains usable without horizontal overflow.
Grounded by Time or Page
The citation changes with the source:
- Audio and video answers point back to transcript timestamps.
- Document answers point back to pages and extracted passages.
That distinction matters. A document should never pretend to have a timestamp, and a video answer should remain easy to verify against the moment it came from.
Private by Default
Uploaded sources remain private. Abstruck requests short-lived, authenticated access only when the current user needs to view or process a file. The browser does not construct or store permanent public storage URLs.
This release is a step toward a broader idea: the study interface should change to fit the source, while the underlying system for grounded understanding stays consistent.
