Increased preload raises stroke volume via the Frank–Starling mechanism.
Mechanism
Greater end-diastolic volume stretches sarcomeres → optimal actin–myosin overlap → more forceful contraction.
Clinical
Curve flattens in systolic heart failure — fluid overload no longer translates to output.
High-yield
↑ preload → ↑ stroke volume, up to a physiologic limit.

How it works

One path: your PDF becomes cards you actually review.

01

Upload and preview your PDF

Try the first pages before signing up. GuruOwl reads your source, drafts atomic cards, and keeps a page reference on every one.

02

Review and approve every card

Fix the wording, drop the weak ones, keep what you will actually study. Nothing enters your deck until you approve it.

03

Review the same deck anywhere

Start spaced review in the browser or open the same deck in the GuruOwl iPhone app — your schedule and progress follow you. Export a standard .apkg whenever you want it elsewhere.

Your deck, everywhere

Your deck doesn't stop at the download

The same cards, the same schedule, the same progress — pick up on the web or on your iPhone without re-importing anything. Already an Anki user? Native sync and a standard .apkg keep that door open too.

The difference

Standard makes the deck. Expert reads the diagrams.

Start with an editable, exportable Anki deck. Choose Expert when labeled figures should become Image Occlusion cards too.

Structured, not flat

Every card carries the mechanism, a clinical correlation, and the high-yield takeaway — the depth AnKing decks are known for.

Expert · Image Occlusion

Expert finds labeled diagrams in your PDF and turns each into masked active-recall cards.

Source-linked and easy to verify

Cards keep a reference back to the page they came from, so you can check any answer against your own source. On Expert medical decks, cards that deviate from board standard are flagged for you to review — never silently rewritten.

Deck styles

Generate in the exact style of a deck you trust

Pick a famous deck — AnKing, MileDown, Core2k — and GuruOwl writes your new cards in its voice: the same cloze patterns, formatting and tags. Not a generic template; the real thing, learned from the deck itself.

Features

Everything around a usable Anki deck

Source-aware generation, inline editing, standard export, sync, and review — without trapping your cards in a chat.

Highlight Detection

AI reads highlighted passages in your PDF and focuses card generation on those areas.

Generates […] fill-in-the-blank cards automatically where appropriate.

Diagram Occlusion

Expert decks find the labeled diagrams in your PDF and mask each label into an image-occlusion card for active recall.

Source Traceability

Each card links back to the original page number, so you can verify the source.

Common Questions

Can't find what you need? Reach out to our support team.

You can — and it's fine for a one-off explanation. The difference is GuruOwl is built around your goal, not a single chat: it turns your material into atomic, Anki-formatted cards tuned to what's testable, exports a real .apkg, and then actively grills you and spaces reviews so it sticks. ChatGPT explains it once; GuruOwl makes you remember it.

Yes. We detect highlighted regions and annotations in your PDF. The AI uses them to prioritize which content to turn into cards. If your PDF has no highlights, the AI generates from the full text instead.

The quality is generally good for structured content like textbooks and study guides. For complex or ambiguous material, you'll want to review the output — that's why we include a split-screen review step.

Yes. We export standard .apkg files with proper field mappings and Cloze deletion support. Import directly into any Anki client — desktop, mobile, or web.

Yes — on the Expert tier. GuruOwl finds the labeled diagrams in your PDF (anatomy plates, schematics) and turns each into an image-occlusion card with its labels masked, alongside richer mechanism / clinical detail on every card. Pick Expert on the generate panel; it costs 3 credits per page versus 1 for Standard.

Turn one PDF into a deck you can keep.

Preview real cards before signup, then edit, export, sync, and review the finished deck wherever you study.
