## What is Cerebo?

Cerebo is a flashcard maker for subjects that don't fit on a plain index card. Build rich cards with LaTeX math, code, tables, graphs, images, audio and PDFs, then let spaced repetition decide what you see and when.


BUILT FOR REAL SUBJECTS

Most flashcard apps give you two text boxes. Cerebo gives you a block editor: stack text, math, code, tables and media in any order, on the front and the back of a card.

• LaTeX math, rendered properly, inline or as display equations
• Function graphs: plot curves, or a 3D surface you can rotate with a finger
• Syntax-highlighted code, Markdown tables, headings and lists
• Images, audio recordings and PDF attachments
• Extract text from a photo or scanned page with OCR
• Cloze deletions: hide any part of a card and reveal it as you go
• Link related cards, read any card aloud, or translate it in place


TEST YOURSELF

Every deck has a Test button, and tests never change your review schedule.

• Match: pair each front with its back against the clock, on any iPhone or iPad
• Practice Test, with Apple Intelligence: true or false, multiple choice and written questions. Written answers are checked for meaning
• Print a deck or export it as a PDF to study on paper


MAKE CARDS, ASK AND QUIZ WITH APPLE INTELLIGENCE

On iPhones and iPads that support Apple Intelligence, Cerebo has a chat that runs entirely on your device:

• Turn a PDF, Word document, photo, scan or web page into a deck, or record a lecture and make cards from the transcript
• Make a study guide from the same document: an overview, the main points and key terms
• Pictures come along: a PDF's figures appear on the cards about them, and on iOS 27 Apple Intelligence reads photos, handwriting and diagrams
• Graphs, tables, equations and code are added where they help, and you review every card first
• Ask questions about your own cards, and see which cards the answer came from
• Get quizzed on a deck or a topic: answer in your own words, typed or out loud, and choose the rating yourself
• Generate a card's answer, or fill in your own answer template (meaning, synonyms, example)
• Share a page from Safari with "Make Cards in Cerebo"


SPACED REPETITION THAT DOES THE WORK

Cerebo schedules each card with the SM-2 algorithm. Cards you find easy move out to longer intervals; cards you struggle with come back soon.

• A per-deck daily limit on new cards. Reviews are never capped
• Browse mode to read through a deck without being tested
• Statistics with a review heatmap, retention rate and a forecast for the days ahead


BRING YOUR EXISTING DECKS

• Import Anki .apkg and .colpkg files with media, cloze, reverse cards and nested decks
• Paste a Quizlet export to bring a set across
• Import into an existing deck, or copy cards between decks. Duplicates are skipped
• Import and export CSV and JSON, and export back to .apkg any time


EVERYWHERE YOU STUDY

• Apple Watch app for reviewing on your wrist
• Scan to Cards and Record a Lecture in Control Center, on the Lock Screen or the Action button, and a Quick Capture widget
• Home Screen and Lock Screen widgets showing what's due, and a Live Activity while you study
• A library sidebar on iPad and iPhone Duo
• Siri and Shortcuts, daily reminders, and study sessions added to your calendar
• Full keyboard, Dynamic Type and VoiceOver support
• In English, Spanish, French, German, Italian, Portuguese, Japanese, Korean and Chinese


YOUR DATA STAYS YOURS

Cerebo collects nothing: no accounts, no analytics, no advertising and no tracking, and the app makes no network calls of its own. The chat runs on your device, so what you write, attach or record is never sent to a server.

Everything works offline. iCloud sync moves your decks between your own devices through your private iCloud account, and one switch turns it off.


FREE: NO ADS, NO SUBSCRIPTION

Cerebo is free. No subscription, no ads, and nothing to buy inside the app.

## Version history (last 3 releases)

### 1.1 — 2026-10-23

Cerebo 1.1 adds a Test button to every deck, and a chat that makes cards, answers your questions and quizzes you, all on your device with Apple Intelligence. Cerebo now speaks nine languages, too.

Test yourself
• Match: pair each front with its back against the clock. On every iPhone and iPad
• Practice Test, with Apple Intelligence: true or false, multiple choice and written questions. Written answers are checked for meaning, and your review schedule doesn't change
• Print any deck, or export it as a PDF

The chat (on iPhones and iPads with Apple Intelligence)
• Make a deck from a PDF, Word document, photo, scan or web page. A PDF with chapters becomes a category with a deck for each. You review every card before it's added
• Then make a study guide from the same document: an overview, the main points and key terms, to read or print with the cards
• Record a lecture, even with the screen locked, and turn it into cards. Only the transcript is kept
• Cards can come with graphs, 3D surfaces, tables, equations and code
• Pictures too: a PDF's figures land on the cards about them, and on iOS 27 Apple Intelligence reads your photos, scans, handwriting and diagrams, a card for each labelled part
• Ask about your own cards and see which cards the answer came from, or ask how to use Cerebo
• Get quizzed on a deck or a topic ("quiz me on antidotes"): answer in your own words, then choose the rating yourself. Say "quiz me out loud" and Cerebo reads each card and listens for your answer
• Create decks, move cards, set reminders and plan study sessions in your calendar. Nothing changes until you confirm

Also new
• Scan to Cards and Record a Lecture in Control Center, on the Lock Screen or the Action button, and a Quick Capture widget for your Home Screen
• On iPad and iPhone Duo, your library sits in a sidebar beside the deck you're working on
• "Make Cards in Cerebo" in the share sheet: send a page from Safari, or text and files from other apps
• Import from Quizlet by pasting a set's export text
• Answer templates: give a deck a layout such as meaning, synonyms and example, and Apple Intelligence fills it in for each card
• One read-aloud voice for the whole app, replacing the per-deck setting. Automatic matches each card's language
• Shortcuts actions to find cards, add a card or open the chat
• Cerebo is now in English, Spanish, French, German, Italian, Portuguese, Japanese, Korean and Chinese

### 1.0.1 — 2026-09-20

Cerebo 1.0.1 is built for iOS 27 and ready for iPhone Duo.

iPhone Duo
• Fold it like a laptop to study: your card on the top panel, large rating buttons where your thumbs are, and a Show Question button to flip back.
• The math, code and graph editors show the finished result on the top panel while you type below. With the keyboard up, switch between Edit and Preview.

Everywhere
• Inline math such as 2π and π/2 now reads as symbols, not LaTeX source.
• Apple Intelligence can write π in graph ranges, and Cerebo plots it.
• 3D surfaces label their axes x, y and z.
• The search button uses Liquid Glass on iOS 26 and later.
• On iPad, cards and rating buttons sit in a comfortable reading column.
• "Generating answer…" shows while Apple Intelligence is working.

Fixes
• Math blocks now appear on first reveal on iPhone Duo.
