What ForthWrite is
ForthWrite is an AI email writing tool built around one idea: replies should sound like you. It learns your style from the emails you actually send, capturing tone, sentence rhythm and the way you sign off, and it keeps adjusting as you edit its drafts. When mail arrives it writes a reply in the background, so there is a draft waiting when you open the thread. It reads the full thread, including forwarded and nested quoted content, and addresses each question raised rather than giving a generic acknowledgement. It supports several models including OpenAI, Claude and Gemini, and includes a prompt laboratory with version control, A/B testing and an optimizer. There are 10 free drafts per week with no credit card required, plus a 14-day professional trial and a 60-day refund guarantee.
What you can do with it
- Generate reply drafts in your own voice from a full email thread
- Get a draft waiting in the background when mail arrives
- Handle multi-question threads without re-reading everything
- Test and version prompts, and track acceptance rate, similarity and time saved
- Batch process multiple threads at once
Who it is for
- Professionals who spend hours a day answering email
- Fast-paced workers who need quick, consistent replies
- People who care that their correspondence sounds like them rather than like a bot
- Teams that want measurable time savings on routine correspondence
What to watch out for
The free tier is 10 drafts per week, which runs out fast if email is a big part of your job, and paid pricing is not published on the page. The workflow described is a Chrome extension writing into Gmail, so if you live in Outlook or a webmail client, that flow does not apply. And voice matching needs a decent body of sent mail before the output genuinely sounds like you; in the first days the drafts will be close but generic, and editing them is part of the training process.
