Description
ForthWrite is an AI email writing tool that drafts replies in your voice. It works through a Chrome extension inside Gmail, Outlook, and LinkedIn messages, so you can open any thread and get a polished, on-brand reply ready to send. Unlike generic AI email tools that produce a draft from a prompt, ForthWrite learns specifically how you write by comparing each AI draft to what you actually sent and using the gap as a training signal.
Setup takes a couple of minutes: add ForthWrite to Chrome, spend a short time on your persona, and start drafting inside your inbox. When you open a thread, you click Generate Draft to get a reply in your voice, which you can edit or send as-is. Every edit you make teaches ForthWrite what to keep and what to drop, and a dashboard shows how drafts get closer to your style over time.
ForthWrite emphasizes privacy and control: it stores your sent emails to learn your voice, encrypted and isolated to your account, never shared or trained on shared models, with BYOK credentials encrypted at rest and one-click data wipe. A free plan includes 10 drafts per week with no credit card, and paid plans start at $15 per month with unlimited drafts, backed by a satisfaction guarantee.
