AI email drafting that writes in your own voice, inside Gmail and Outlook
ForthWrite reads emails you have already sent to build a voice profile, then refreshes it roughly every 50 captured emails so drafts keep tracking how your writing evolves.
Pro users can have replies waiting when they open Gmail, and clear dozens of threads in parallel instead of writing each one by hand.
Drafts adapt tone to the person you are replying to and treat follow-ups, intros, and status updates as genuinely different jobs rather than one generic template.
Version control and A/B test your prompts, then track acceptance rate, voice match, and intent mix on a measurable improvement curve.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
