Write with AI, Without Sounding Like AI - Anywhere You Browse

ToneClone is an AI writing tool that trains on your writing samples to match your unique tone and style. Instead of generic AI text, you get content that sounds like you, on any website.

Why ToneClone?

✓ Your Voice, Not AI's
Train AI personas on your writing samples - URLs, text, or files. The AI learns your style and generates content that matches your tone.

✓ Enhanced Platform Support
Special features for Gmail, Twitter, GitHub, Slack, and Google Voice. But it works on every other site too - LinkedIn, Reddit, Zendesk, Asana, Notion, forums, help desks, CRMs, and more.

✓ Context-Aware Writing
Automatically pull in email threads, tweets, code reviews, and page content with @extractors. The AI understands what you're responding to.

✓ Fast Iteration
Quick actions let you make content shorter, longer, more professional, more casual, spicier, or calmer with one click.
