Features

Features that respect your time.

Everything listed here is live in the app today — build a pack, drill it, test yourself, ask about it and export it, all from one workspace.

The core workspace

Notes → clean PDF study pack

Paste up to 60,000 characters or upload a PDF, Word file or Markdown. A planning pass maps every concept in your source, then an expansion pass writes chapters, key concepts, worked examples, formulas, exam tips and a glossary — with a live PDF preview beside the editor.

Your library & study lists

Every pack is saved to your library with its subject icon and colour. Search, filter and reopen any pack, keep editing it, and re-download the PDF as many times as you like without using another generation.

Paper-style flashcards

Each pack generates a deck automatically, or generate a deck on its own. Flip cards front/back, self-rate your recall, and drill only the cards you keep forgetting.

Adaptive practice tests

Build a test from a pack, several packs, a deck or a fresh upload. Choose exam level (KS3, KS4/GCSE, A-level, undergrad), difficulty, question count and types. Difficulty adapts to your confidence, feedback quotes the exact line from your notes, and missed questions convert to flashcards in one click.

AI tutor with citations

A chat built for studying: attach a pack for full document context and every answer is grounded in your own material with the source quoted. Ask for a simpler explanation of anything you got wrong.

Exports

Download packs as PDF, Word (.docx), PowerPoint (.pptx), Markdown or plain text. Decks export as PDF or Anki-compatible CSV. Everything you have exported is listed on the Exports page.

Study tools

Six tools for the material that isn't already typed up. The YouTube summarizer is on the free plan; the rest unlock on Half Pie, and the AI Paper Marker on Whole Pie.

YouTube Video Summarizer

Paste a link and get a structured summary with timestamps, key points and study questions. Included on the free plan.

TikTok Video Summarizer

Pulls the transcript from a TikTok link and turns it into clean, usable study notes.

AI PDF Summarizer

Long PDFs are chunked and summarised section by section, so nothing important is dropped from a full chapter.

Audio to Study Notes

Upload a lecture recording or voice memo and get a transcript plus structured notes you can turn into a pack.

Video to Text Converter

Extract spoken content from a video file into a clean, readable transcript.

AI Paper Marker

Marks your written answers like an examiner: per-question marks, highlighted mistakes, corrections and an overall report with how to improve.

Progress

Study stats

A consistency heatmap, study streaks, session history and per-subject activity so you can see what you have actually revised.

Achievements & XP

Earn XP for sessions, packs, cards mastered and streak days, and unlock achievement badges as you go.
