Overview
IELTS Writing Checker is a specialized tool designed to help IELTS test takers improve their writing performance. It evaluates essays based on the four official IELTS criteria: Task Achievement, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. The tool provides an estimated overall score, criterion scores, and actionable feedback, with paid plans offering sentence-level annotations and rewrites. It supports Academic Task 1, General Training Task 1, and Task 2, and even accepts visual inputs for Task 1.
Maker/OS, on the other hand, is a knowledge library and pathway system for digital founders in the AI era. It aims to answer critical questions like what to build first, whether an idea is worth pursuing, and how to make decisions without a technical background. The knowledge library covers ten areas of product building, from foundations to case studies, with self-tests and flashcards for retention. Pathways turn this knowledge into step-by-step sequences for stages like validating an idea, planning an MVP, launching, and building an AI copilot.
