Drop in a lecture, PDF, video or link. Heyblocks turns it into structured study tabs using reusable Blueprints. Same source, your structure.
Every study tool gives you a chat. Heyblocks gives you tabs — real study surfaces, organized by a reusable Blueprint you control.
Recordings, PDFs, slides, docs, web links, YouTube, or live web research — drop in whatever your work starts with.
A Blueprint is a reusable set of tabs you want generated. Use one of ours, fork it, or build your own and save it.
Each tab is a real, interactive study surface — flip flashcards, take a quiz, edit the transcript and regenerate any single tab. Save the Blueprint, reuse forever.
No demo accounts, no mockups — this is the actual app. Add a tab, watch it fill, save the layout as a Blueprint.
Spin up a tab for anything — a summary, key concepts, flashcards, a quiz. You decide what the output looks like before a single word is generated.
Heyblocks reads your full source and writes every tab from it — grounded in what you actually dropped in, not a generic summary. Don't like one tab? Regenerate just that one.
Happy with the layout? Save it. Every future source — next week's lecture, the next chapter — auto-generates that exact structure. Build your study system once.
The Lecture Notes Blueprint, run on a Cell Biology lecture pack, rendered the way Heyblocks actually outputs it — clean markdown with tables, math and lists. Switch tabs.
TL;DR. Cells convert glucose into ATP, their energy currency, across three linked stages: glycolysis, the Krebs cycle, and the electron transport chain. Most of the ATP is captured in the final stage, inside the mitochondria.
chemiosmosis.The mitochondrion isn't just the powerhouse. It's where electrons stop moving and start meaning something.
The five ideas to actually remember from this lecture:
| Term | Definition |
|---|---|
| ATP | Adenosine triphosphate, the molecule cells use to store and spend energy. |
| Glycolysis | A 10-step pathway splitting one glucose into two pyruvates in the cytoplasm. Net: 2 ATP, 2 NADH. |
| Krebs cycle | Reactions in the mitochondrial matrix that strip electrons off acetyl-CoA, loading NADH and FADH2. |
| Electron transport chain | Inner-membrane proteins that pass electrons down a gradient, pumping protons to power ATP synthesis. |
| Chemiosmosis | Diffusion of H+ through ATP synthase, releasing energy that gets captured as ATP. |
1. Most of the ATP in cellular respiration is generated in which stage?
2. What is the terminal electron acceptor in aerobic respiration?
Start with a built-in Blueprint, fork it, or build your own and save it. The same source produces wildly different output depending on which one you pick.
Everything you need from a recorded lecture or slide deck.
Lock it in before the test — study guide, cards, practice.
Turn a chapter, paper or article into something you can revise from.
For problem sets and lab work — formulas and methods kept straight.
Vocab, grammar and example sentences from any source — built for learners.
When you're short on time — the gist plus a deck, nothing else.
One thing, fast. One source, one deck — export straight to Anki.
Mix any tabs you want — case briefs, meeting notes, research briefs. Save the layout; every future source rebuilds it.
PDF, Anki (.apkg), Word (.docx) and plain text. Your study set leaves with you — no lock-in.
Flashcards come with a real review scheduler — study what's due, when it's due, until it sticks.
Give it a topic and Heyblocks searches the web, reads multiple sources, and writes it up with citations.
Fix the transcript, then regenerate a single tab — not the whole note. Tune the output without starting over.
Fast mode for quick drafts; Pro mode when you need the deepest, most careful generation.
GDPR compliant. Export or permanently delete everything, any time. Transactional email only.
I drop in a source and get organized output within minutes instead of rebuilding everything by hand.
Really great for summarizing and organizing meeting content. Long recordings are much easier to review afterward.
Perfect for catching up fast. Clean, structured notes without the usual manual cleanup.
A reusable set of tabs you want generated from a source — like Summary + Flashcards + Quiz. Pick a built-in one, fork it, or build your own and save it. Every future source rebuilds that exact structure.
Audio and video recordings, PDFs, Word docs, images, web links, YouTube videos, pasted text — or a research topic, which Heyblocks searches the web for. Multiple sources merge into one note.
Yes. The interface and Blueprints are available in 7 languages — English, German, Spanish, French, Portuguese, Italian and Polish — and output is written in the language of your source.
Yes — flashcards export to a real Anki .apkg deck, with review scheduling built in. You can also export any tab to PDF, Word (.docx) or plain text, or copy it to your clipboard.
Yes. You can start for free with no credit card. New accounts get a usage allowance to try it on real sources before deciding if you need more.
Heyblocks is GDPR compliant. You can export your data or permanently delete your account and everything in it at any time. We send transactional email only — no marketing spam.
Free tier. No credit card. GDPR compliant. Export to PDF, Word or Anki when you're done.
