NB: Agent API Keys are currently disabled, live testing will not work.

Frontend — editorial landing page, and a protected /studio with paste area, CEFR/tone/persona/nativeness/domain/variation controls, live analysis panel, multiple rewrite variations, editable output, quality-reviewer scores, style-brief inspector, and save-to-learn.

Visitors sign up and confirm their email before running rewrites. 

The Platform:

  • A complete multi-agent system that analyzes text, applies writing personas, rewrites with precision, ensures natural variation, and reviews for quality

  • A comprehensive knowledge base covering CEFR levels (A2–C2), 8 writing personas, tone profiles, style guides, and an idiom library organized by category

  • Dynamic prompt loading so you can iterate on instructions without touching code

What Users Can Do:

  • Paste text and instantly see detailed analysis (reading level, tone, vocabulary, passive voice frequency, repeated phrases, etc.)

  • Choose a target CEFR level, tone, and writing persona to transform their writing

  • Get multiple rewrite variations with natural rhythm and varied sentence structure

  • Edit and save rewrites; the platform learns from their edits to personalize future outputs

  • Compare their original text against the generated version to understand what changed

The Backend:

  • Modular agents that each handle one job (analysis, persona selection, rewriting, variation, review, learning)

  • Token counting and caching to keep costs down

  • Gemini integration with intelligent model routing

  • Persistent storage of rewrites and learned preferences

Technology stack: React for the frontend and Node.js for the backend.

Next Step After Purchasing This App — Add Your API Key:

  1. Go to Google AI Studio and create a free API key

  2. Open your .env file and replace the placeholder:

GEMINI_API_KEY=your_actual_api_key_here

  1. Save and restart your app

Once you've added your real API key, the app will start transforming text instead of echoing it back. Try uploading some sample text, select a CEFR level and persona, and you'll see the agents working together to rewrite it.
