ForthWrite vs superReply

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.

The extension appears directly in Gmail and Outlook web, so you never leave the thread you are answering.

Pick the tone of voice that fits the situation — professional for a client, casual for a friend — and the suggestions adapt.

A single click surfaces several ready-to-send reply options so you are never stuck staring at a blank compose box.

Beyond Gmail and Outlook, superReply integrates with Chrome, WhatsApp, Slack, LinkedIn, Upwork and Fiverr.
