How it works

From a page of your book to a set of drills — in about the time it takes to make tea.

No template, no re-typing, no student app. Here's the whole flow, step by step.

01
Upload

PDF, PPTX, DOCX, or a photo.

02
Extract

AI-powered OCR reads the page.

03
Classify

Items typed + reviewed.

04
Drill

Phonics-correct audio rendered.

05
Publish

Online or offline bundle.

Step 1 · Upload

Bring the coursebook — as it is.

Drag in a file or take a photo of the page. Native PDFs, scanned PDFs, PowerPoint, Word, and images all work. If a page is a shared file you already use, that's exactly what to upload.

  • Up to 25 MB per file
  • No cleanup or conversion needed
  • Re-upload safely — identical files de-duplicate

Step 2 · Extract

The machine does the reading.

Native text is pulled directly; scanned or image-only pages go through AI-powered OCR. A per-page “text-trust” check catches garbled fonts and re-reads them, so you never get gibberish.

  • AI vision model with automatic fallback for scans
  • Automatic re-OCR of unreadable text layers
  • Tables recovered as structured vocabulary rows

Step 3 · Classify & review

Every item gets a job.

Titles, vocabulary, sentences, questions and answers are identified automatically. Anything the system isn't sure about lands in a fast review queue — approve, edit, or reject in a keystroke.

  • Confidence-scored, worst-first review
  • Keyboard triage: j/k move, a/e/x act
  • Low-quality lessons flagged, never silently shipped

Step 4 · Drill

Hear it the way a learner should.

Each item is rendered with the right voice and the right pattern: strict, phonics-correct audio for drilling; natural, expressive audio for stories. Words highlight in sync as they play.

  • Word-repeat, sentence-repeat, repeat-after-me, backchaining
  • IPA/SSML precision + timed pauses for practice
  • Karaoke highlighting; per-learner speed control

Step 5 · Publish

Hand it to students — anywhere.

Publish to the in-app viewer, or export a single self-contained HTML bundle. That bundle carries all images and audio inside it and opens in any browser with no server and no internet.

  • Share a link, or ship a USB stick
  • No student login, no app to install
  • Same clean viewer, online or offline
