About Shelf
A quiet library built for serious study
Shelf is a study workspace that keeps your material and progress together. Upload PDFs and notes, highlight as you read, ask Tutor questions grounded in your sources, practice with quizzes, and return to the page and plan you left behind.
Your material
Everything you add stays private to your account. Organize pages into sections you control.
Tutor on demand
Ask questions on a highlight or the full page. Summaries, notes, and mind maps from what you uploaded.
One calm dashboard
After you sign in, your calendar, library, pinned pages, and Tutor live in one profile.
What Shelf includes
A calm workspace for your own material — upload, read, ask, and plan without switching apps.
Sketch notebooks & research Docs
Create multi-sheet sketch notebooks or typed Docs in the same collection as your PDFs — with citations, outlines, and export for research writing.
Citations & bibliography
Cite in APA, MLA, Chicago, or IEEE. Import BibTeX, cite from library highlights, and refresh a References block as you draft.
Your sections
Group uploads into sections — like folders — and open any page whenever you need it.
Telegram import and send
Forward coaching PDFs to the Shelf bot, then send a library PDF back from Share — same reader, highlights, and Tutor as in-app uploads.
Tabs and split view
Open up to 15 pages in tabs, compare two documents side by side, and resize library and Tutor panels.
Highlight as you read
Mark passages on pages you uploaded. Colors stay with the page for later revision.
YouTube lectures
Paste a video or playlist into your library. Watch in the reader, stamp timestamps into notes, and split a PDF beside the lecture.
Paraphrase & originality
Rewrite selections in your own words and check overlap with your library and syllabus. Premium can run web plagiarism when a vendor key is set.
Ask on a selection or the page
Highlight a paragraph or ask about the whole page. Tutor answers from your material.
Summarize, notes, mind maps
Turn a long page into a recap, revision bullets, or a scannable mind map.
Goal-aware Tutor
Pick a study track so answers stay relevant to what you are working toward.
Practice quiz
Make multiple-choice and written quizzes from a page, your library, or an upload.
Dashboard and calendar
Track activity and plan your week with time-based items that link back to your pages.
AI Planner and calendar
Turn a goal or uploaded outline into a schedule, then adjust items in day, week, or month view.
