Features
One upload becomes a complete, phonics-correct listening lesson.
Every capability below is part of the same pipeline — you don't stitch five tools together. Bring a coursebook; leave with drills your students can practise anywhere.
① Ingest anything
The books you already own — in any format.
Every common file type
PDF (native and scanned), PowerPoint (PPTX), Word (DOCX), and image uploads — PNG, JPG, WebP. Up to 25 MB per file.
A photo of the page works
Snap a textbook page on your phone and upload it. No scanner, no clean PDF, no re-typing required.
Structure preserved
Headings become sections, slides stay slides, and column-aware tables are recovered as structured vocabulary rows.
② Extract & classify
It reads the page — then understands it.
AI-powered OCR
Scanned or image-only pages are read by an AI vision model with automatic fallback, so even a photographed textbook becomes editable text.
Text-trust re-OCR
Pages with garbled CID fonts or mojibake are detected automatically and re-read — no more silent “gibberish in, gibberish out”.
Pedagogical classification
Each item is typed: title, vocabulary word, example sentence, comprehension question, answer. The audio pipeline then knows how to drill each one.
Confidence & review queue
Low-confidence items are flagged into a keyboard-fast queue (a approve, e edit, x reject) — so nothing wrong reaches students.
No silent failures
A lesson that recovered no real content is marked “needs review”, never a false “100% done”. One click re-extracts it.
Quality score per lesson
Every extraction gets a quality score and flags, recorded per run — so you always know how well a book was read.
③ Drill — the moat
Phonics-correct audio, not generic narration.
This is what sets Languages Lab apart: audio engineered for young learners to hear the sounds, not just a smooth voice reading a paragraph.
IPA / SSML precision
A precision speech engine driven by strict SSML with IPA phoneme tags and timed breaks — each syllable and sound rendered clearly for phonics practice.
Multi-engine routing
Drills use the strict phonics voice; storytelling and dialogue use a natural, expressive voice. The right engine for each pedagogical job.
Real drill modes
Word-repeat, sentence-repeat, AI-chunked repeat-after-me, and backchaining — the patterns teachers actually use in class.
Karaoke highlighting
Words light up in time with the audio, using real word-boundary timing — so learners follow along and read as they listen.
Learner-tunable
Adjustable playback speed and repeat-pause length, remembered per learner — slow it right down, then speed up.
Vocabulary drilling
Vocabulary rows become full word-drills; example sentences become sentence practice — automatically, from the table on the page.
④ Deliver anywhere
Online, or completely offline.
In-app student viewer
A clean web viewer with per-item players, drills, images, and karaoke — the same look and feel as the studio, light or dark.
Self-contained offline bundle
Export one HTML file with every image and audio clip embedded. Students open it from a USB stick or shared folder — no login, no app, no internet. Ideal for low-connectivity classrooms.
⑤ Run it like a business
Built as real multi-tenant SaaS.
Multi-tenant isolation
Every school's data is isolated at the database level (row-level security), proven with automated tests.
Per-seat billing
Self-serve plans and subscriptions via Stripe, with server-side quota enforcement and a usage dashboard.
Usage & cost ledger
Every AI call — OCR, classification, TTS — is metered per tenant, so spend is transparent and attributable.
Privacy-aware
GDPR/COPPA-conscious design for a young-learner audience: data export, erasure, and retention controls.
