Prism writes

Hi Michael,

Thanks for your patience as we've been working through this. I wanted to give you a realistic update on the Jones project timeline.

Our team is currently managing several high-priority deliverables, and to ensure we give your project the attention it deserves, we'd like to propose extending the deadline by one week.

Would that work on your end? Happy to discuss if you'd like to talk through the details.

Best,
Sarah

I write 50+ emails a day. Prism saves me at least an hour. The output actually sounds like me — my team can't tell the difference.

Other AI tools write like robots. Prism somehow captures my voice — direct but warm. It's uncanny.

The 2-minute setup actually works. I was skeptical, but Prism nailed my writing style immediately. Huge time-saver.

Frequently asked questions

Everything you need to know about Prism.

Prism uses a quick voice quiz that presents you with writing choices — "Would you start an email this way or that way?" Based on your preferences, we build an instant voice profile. It's like a personality test for your writing. The more you use Prism and make corrections, the better it gets.

ChatGPT requires you to explain your style every time and craft careful prompts. Prism remembers you. It knows you prefer "Hi Sarah" over "Dear Sarah," that you like short paragraphs, and that you sign off with "Best" not "Regards." It's a translator, not a chatbot.

Your privacy is fundamental to Prism. We don't train our models on your data, sell it, or share it. Your messages and voice profile are yours alone. We're building a tool you can trust with your most sensitive communications.

Prism lives in your browser as an extension. It works wherever you write — Gmail, LinkedIn, Slack, Twitter, and any text field on the web. Just hit the keyboard shortcut, type your raw thought, and paste the polished result. Chrome and Safari extensions are included.

Yes. Prism is $15/month with no contracts or commitments. Cancel anytime from your account settings. We don't believe in locking people in — if Prism isn't saving you time, you shouldn't pay for it.
