I built Chatty as a weekend project after noticing most AI writing tools focus on generating or correcting text, rather than teaching users how to improve their writing skills.

Key features: - Knows your text style, and will adapt its suggestions accordingly - Detailed grammar rule explanations with context - Writing style development (formality, tone, context awareness)

The app is completely free to use - I built it to help people actually improve their writing skills rather than just relying on AI corrections.

Tech stack: Next.js, Mantine, Gemini 2.0 Flash Lite & Gemini 2.0 Flash
