Write & Improve (Cambridge)

What it actually is

Cambridge's own automated marking tool: write to one of hundreds of prompts, and within seconds you get an estimated CEFR level plus sentence-by-sentence highlights of what needs fixing, then resubmit and watch the score move. For a self-studying learner with no teacher, this closes the biggest gap in solo English study — nobody to correct your writing. The feedback is automated, so it flags problems more reliably than it explains them, and richer features and exam-style tasks sit behind the paid tier.
