Today, we’re excited to announce the release of Gakku’s first Lesson Map — Opinion Writing: a fully guided, AI-powered writing curriculum that helps students build clarity, structure, and confidence in English writing.
Gakku is not another chatbot or grammar checker. It is a true AI writing tutor, designed to teach, guide, and grow with the learner.

A Lesson Map is a structured sequence of AI writing lessons, each delivered as an interactive Lesson Card. Every card teaches one key writing skill—through real-time dialogue, not lectures.
You’ll practice skills such as:
- forming a clear stance
- giving reasons and examples
- organizing ideas logically
- writing strong introductions and conclusions
- improving clarity and coherence
These aren’t static explanations. Your AI writing tutor speaks to you in real time, gives tailored feedback, and adapts to how you think.
The map ends with a Boss Challenge, where the AI tutor guides you through planning, drafting, revising, and polishing a complete essay.

Gakku’s curriculum is standards-aligned and globally relevant, drawing from:
- CCSS (U.S. Common Core State Standards)
- CEFR (European language proficiency framework)
- GCSE (UK English curriculum)
Our team designed the writing journey to be:
- developmentally appropriate
- research-backed
- scaffolded for real skill progression
- applicable to students around the world
This is not random AI content. It is a thoughtfully designed curriculum built on educational research—delivered by an AI writing tutor who can teach every card with consistency and clarity.

Not a tool. Not automated grading. A thinking partner.
Gakku offers a completely new interaction model:
✔ Full-duplex real-time voice — talk naturally, without waiting
✔ Adaptive teaching — explanations match your level
✔ Guided reasoning — the AI tutor asks questions that build logic
✔ Live revision coaching — improve structure, clarity, and flow
✔ A persistent memory — your tutor grows with you
This is the first AI writing tutor that feels like a companion — not a chatbot, not an autofill machine, but someone who helps you practice and think.
