What is Forthwrite AI?
Forthwrite AI is an intelligent email writing assistant that learns your unique writing style and becomes more accurate with every email you send. Unlike generic AI tools, Forthwrite captures your tone, sentence rhythm, and sign-offs by analyzing your real sent emails. Setup is effortless: install the Chrome extension, connect to Gmail or Outlook, and spend two minutes defining your persona. After that, Forthwrite automatically drafts replies in the background as emails arrive, so when you open a thread, a polished response in your voice is already waiting.
Key features include auto-drafting, batch drafting for dozens of threads simultaneously, and smart retrieval that grounds new drafts in your best prior work. The platform supports nine AI providers—including Claude for tone, GPT for reasoning, and Grok for cost—giving you flexibility to choose the best model for each task. Forthwrite reads the full thread, including forwards and nested intros, and addresses every open question. You can edit drafts or send them as-is; each edit teaches the system what to keep or drop, continuously improving accuracy.
Use cases range from busy professionals managing high email volumes to teams needing consistent brand voice across communications. Technical details include encrypted storage of your sent emails (isolated to your account, never shared or trained on shared models), BYOK credentials encrypted at rest, and one-click data wipe. The dashboard tracks acceptance rate, similarity score, edit-distance, and time-saved, showing a curve of improvement over weeks. You can version-control prompts, A/B test against your sent mail, and let the optimizer suggest edits grounded in your data. Forthwrite offers 10 free drafts per week with no credit card required, and you can export your full data anytime. It works in Gmail, Outlook, and your browser, making it a seamless addition to your workflow.
