Lesson generation
Turns your PDFs, class recordings, or student notes into structured lessons with exercises calibrated to the student's CEFR level. Every lesson is checked before a student sees it, and broken exercises are repaired or replaced.
The AI inside ACE
Not a chatbot. An English teaching engine.
ACE's AI is purpose-built for ESL. It plans lessons from your school's curriculum, grades pronunciation phonetically, remembers each student's history, and uses your teachers' corrections to guide future grading. Schools and teachers stay in control: the AI is the assistant, not the boss.
Hi Maria! Yesterday you mixed past tense forms. Want a 4-min drill before today's lesson?
Sure. I always say "I have went" instead of "I went".
Classic Simple Past vs Present Perfect. I'll save this in your memory so we revisit weekly until it's automatic.
Perfect.
What makes it different
5 jobs. Teacher-aligned. Built for ESL.
Phonetic pronunciation grading
Scores spoken answers phonetically, so accents and near-misses are flagged in yellow instead of marked wrong. Optional real-time streaming highlights words as the student speaks.
Long-term student memory
Mistakes, wins, lesson topics and teacher corrections are remembered. The next lesson is built from the most relevant history, not just yesterday's class.
Teacher calibration loop
When a teacher overrides an AI grade or flags a bad question, that correction feeds the next generation. The AI adapts to YOUR school's teaching standard instead of a generic one.
Rubric-calibrated exam grading
The CELPIP grader scores writing and speaking against official-style rubrics, returns an estimated band, and marks up the student's own text with colour-coded edits and vocabulary upgrades. Bands are estimates, not official scores.
How it stays trustworthy
Built for schools, not for buzzwords.
Two-tier AI sized to the task
Deep models for grading and lesson generation; lighter ones for fast game prompts and triage. You get accuracy where it matters and speed where it doesn't.
Your data, on a single audit-friendly database
Every student's history lives in one database, and a copy is available on request. Memory search runs inside that database, not in a separate vector service.
Cost ceilings + telemetry
Every AI call is tracked per school and per feature, with budget alerts, and a hard monthly cap can be switched on for any school.
Privacy-first
Consent records, a copy of your data or its deletion on request, built with LGPD and PIPEDA in mind. Audio recordings are deleted automatically after 12 months.
