Overview
IELTS Writing Checker is a specialized web-based tool designed to score and improve IELTS Writing Task 1 and Task 2 responses. It evaluates essays based on the four official IELTS criteria: Task Achievement, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Each review provides an estimated overall score, criterion scores, specific evaluations, and actionable next steps. Paid plans unlock sentence-level annotations, correction suggestions, and rewrites, with up to 50 reviews per month. The tool claims high accuracy, with an average error of 0.49 points compared to official scores, outperforming general AI tools like ChatGPT.
Toku Reader is an iOS app that transforms native Japanese and Chinese content—articles, novels, podcasts, and YouTube videos—into an interactive reading experience. Users can tap any word to see its reading, meaning, and dictionary, without leaving the page. For audio and video, it provides synced, word-tappable transcripts, allowing users to slow down, replay, or shadow lines. The app runs its own JP/CN engine on-device with offline dictionaries, ensuring fast, private, and account-free usage.
