Overview

About ForthWrite

ForthWrite Inbox is a Chrome extension that drafts replies inside Gmail and Outlook, trained on the mail a user has already sent so first drafts read like them rather than like a template; a person still reviews and sends. The company now points it at professional services firms such as accounting and tax practices, advisors and lenders: admins set compliance rules every draft must pass, a draft that breaks one stops and asks the preparer for a written reason, and reporting shows rules, violations and overrides per person. Paid plans can run on the user's own Claude or Gemini key for about 17 percent off. Free use is 10 drafts a week; Pro is $24 a month billed annually or $29 monthly, Teams from $59 a seat with a two-seat minimum. It is built and run by one person in San Diego through Aesir Labs, LLC.

Editorial verdict

Pros & cons of ForthWrite

medium confidence

ForthWrite's draft-in-your-own-voice idea now comes wrapped in a compliance layer aimed at accounting, tax and advisory firms, which is a sharper pitch than the generic email assistant it was a month ago, and the free 10 drafts a week are enough to judge whether the voice match holds on your own sent mail. Price it honestly: the entry tier jumped from $15 to $24-29 a month, it only works in Gmail and Outlook on Chrome, and the whole thing is one founder's product, so weigh continuity before rolling it out to a firm.

Pros

  • Learns tone from the user's own sent mail rather than a generic template
  • Compliance rules stop a non-conforming draft and require a written reason, with admin reporting
  • Free tier and 14-day Pro trial need no card, and a bring-your-own Claude or Gemini key cuts the price
  • A person still sends every message, so nothing goes out unreviewed

Cons

  • Chrome plus Gmail or Outlook web only
  • Entry price rose from $15 to $24 a month billed annually, $29 monthly
  • Teams needs two seats and the annual rate is only 'from' $59
  • Built and run by one person, with no address or governing law in the terms

Best for

  • Accounting, tax, advisory and lending firms that want every client email drafted under written rules
  • Gmail or Outlook users on Chrome with a heavy reply load who want drafts in their own tone
  • Small teams that need per-person reporting on rule overrides

Not for

  • Users of Safari, Firefox or a mail client other than Gmail and Outlook
  • Firms that need a vendor with a team behind it rather than a single operator

Watch out: The $24 Pro price needs a year paid up front ($288); month-to-month is $29, and the old $15 Standard tier no longer exists.
