ForthWrite vs Smart Assistant by Mailbutler

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.

Turn a handful of keywords or bullet points into a full, sendable email, and generate replies framed as positive, negative, or neutral depending on the situation.

Condense long email chains into the key points so you can catch up fast and respond without re-reading every message.

The assistant rewrites and corrects your message for grammar, spelling, and phrasing before you hit send.

Follow-up suggestions combined with open and click tracking tell you which threads are urgent, and the assistant can draft the follow-up for you.
