AI feedback service ready

Learning Modules

The long-term product direction for C1 English Builder is an AI-powered English coach covering the full skill set. Writing is the only active module today. The other cards below are placeholders showing what is planned and roughly how it will work.

Writing

Active MVP

Submit English text and get a mode-based review (Quick Fix, Sentence Review, Full Review). Builds a personal error bank over time.

Active MVP. Endpoint: /api/review.

Open Writing →

Vocabulary

Planned

Build a personal vocabulary list from your errors and review history. Review with spaced repetition.

Future: mine personalErrorListUpdate + sentenceReviews for new items.

Grammar

Planned

Generate grammar drills from repeated error categories in your error bank.

Future: error-category histogram → targeted drill generator.

Reading

Planned

Read a short passage, answer comprehension questions, get vocabulary and comprehension feedback.

Future: static passage library + question bank, no auth.

Speaking (Lite)

Planned

Record a short audio clip, get a transcript back, then review for fluency, naturalness, grammar, and answer relevance.

Future: real audio recording is out of scope for this MVP — placeholder only.

Listening (Lite)

Planned

Listen to a short dialogue, answer comprehension questions, get explanations for any mistakes.

Future: requires TTS / audio asset pipeline. Out of MVP scope.

Placement Test

Planned

Estimate your writing output level with one short writing sample plus a small grammar and collocation quiz.

Future: combines writing + grammar signals into a single CEFR estimate.

Progress

Planned

Track your writing journey: number of reviews, error-bank growth, weakest categories, weekly streak.

Future: no XP / pet / gamification yet — those are explicitly out of scope for this MVP.

What is NOT in this MVP
