ForthWrite is an AI email writing assistant for Gmail and Outlook that learns your writing style from your real sent mail. The more you use it, the more it sounds like you. Get smart drafts in seconds, auto-draft replies before you open your inbox, and maintain your personal voice at scale. Free to start, no credit card required. Works inside Gmail and Outlook on the web.

How it works

ForthWrite captures your tone, sentence rhythm, and sign-offs from your actual sent emails, then uses that profile to generate drafts that match how you write, not a generic AI voice. Every draft you edit or send improves the model over time.

Key features

  • Auto-draft: replies waiting in Gmail before you open your inbox
  • Voice matching from your real sent mail, not templates
  • Recipient-aware drafts that adapt to who you are emailing
  • Prompt Lab for version-controlling and A/B testing your persona prompt
  • BYOK support: bring your own API key for Claude, OpenAI, Grok, Mistral, and more
  • Works in Gmail and Outlook on the web, plus a standalone browser widget
  • Training data export and full data portability

Who uses it

Professionals who send high volumes of relationship-critical email: lawyers, financial advisors, recruiters, account executives, founders, and anyone who wants their inbox handled without sounding like a chatbot wrote it.

Pricing

Free tier includes 10 drafts per week with no credit card required. Paid plans start at $12/month and include unlimited drafts, custom persona prompts, and auto-draft.

Questions & Answers

As answered by people managing PrimeLister and ForthWrite.

Which are the primary technologies used for building your product?

ForthWrite's answer:

Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API

What makes your product unique?

ForthWrite's answer:

ForthWrite learns your writing style from your actual sent mail, not a generic prompt. Every draft sounds like you wrote it because it was trained on how you actually write. It also auto-drafts replies before you open your inbox, so your email is partially handled before your day starts.

Why should a person choose your product over its competitors?

ForthWrite's answer:

Most AI email tools give you a blank box and a "write for me" button. ForthWrite builds a voice profile from your sent history and gets more accurate with every draft you edit or send. Unlike ChatGPT or Gemini, it works natively inside Gmail and Outlook with no copy-paste. Unlike Lavender, it writes the draft, not just scores it.

How would you describe the primary audience of your product?

ForthWrite's answer:

Professionals who send high volumes of relationship-critical email and cannot afford to sound generic: lawyers, financial advisors, recruiters, account executives, consultants, and founders managing their own inbox.

What's the story behind your product?

ForthWrite's answer:

Built out of frustration with AI writing tools that produce text that sounds nothing like the person sending it, and as a way to handle large amounts of daily email. The core insight was that your sent mail is the best training data you already have, and no tool was using it.

    I love PrimeLister

    Where to begin?! Wow. This extension is a game changer!! It has incredible functionality that saves me a lot of time. Time I can now devote to growing my business further. It is user friendly-I downloaded one other extension prior and didn't even get to using it as instructions alone was so convoluted-this one was super easy; I was up and relisting items within seconds! Amazing! It is affordable and an incredible value for money! Best of all, and I think why this extension tops everything else on the market is the customer service! Not a single unanswered question. I raised a query at 4am...and someone was there within seconds! He patiently answered all my questions, listened to suggestions and was so pleasant through it all. Thank you so so much for making a winning tool to help small businesses like me!

    ๐Ÿ‘ Pros:    Great customer support|Customer support|Best customer service|Great documentation|Relisting

    Reseller's best friend

    For the past three months, I've been using PrimeLister. It not only made my life easier, but it also tripled my revenue. Furthermore, the most recent upgrade to the scheduling option made it even better. Send offer to likers is one of my favorite features. It's a fantastic tool for organizing my closet. After using it for a couple of months, I had to request Richard, who is very talented and very cooperative, to give me a professional package for using my PrimeLister account for multiple Poshmark accounts. I would strongly advise it to any posher who resells as an individual or as a professional. HIGHLY RECOMMENDED!

    ๐Ÿ‘ Pros:    Schedule poshmark sharing|Send offer to likers|User-friendly|User friendly interface|Great user experience|Document storage
    ๐Ÿ‘Ž Cons:    Draft listing feature

    ยท Posher at Poshmark ยท
    Most effective way to increase Mercari and Poshmark sales

    I have been always advocating the most effective way to increase my sales is to re-list my items on both Poshmark and Mercari. The only problem was that I was getting tired of filling out the same information over and over as I keep re-listing my items. I hate having to switch back and forth between open tabs and copy-pasting descriptions to create copies of the same listing. I would like to thank a Posher friend who told me about PrimeLister. I started saving myself extra time whilst PrimLister handles all the re-listing jobs.

    ๐Ÿ‘ Pros:    Great documentation|Great customer support|Mercari relisting|Poshmark relisting|Poshmark sharing
    ๐Ÿ‘Ž Cons:    Depop relisting

    ยท Founder at ForthWrite ยท
    I built ForthWrite to fix generic AI email, and I still use it every day

    I built ForthWrite because I kept sending emails that sounded like they came from the same generic AI as everyone else. After launching it, I still use it for my own inbox every day, which is about the most honest endorsement I can give.

    The Chrome extension lives inside Gmail and Outlook on the web. Open a thread, hit Alt+Shift+D, and a draft comes back in your voice, not a template. The free tier is real: 10 drafts per week, no API key, no credit card. Voice matching is included on free, because that is the point.

    What keeps it useful compared to Gemini or a chat tab: it learns from what you actually send. Every edit you make before hitting send becomes a signal. Over time the drafts drift closer to how you really write, and the dashboard shows the improvement curve so you can see it happening.

    The web compose surface lets you draft from forthwrite.ai without installing anything, useful for people who want to try before committing to the extension.

    Standard adds recipient-aware and intent-aware drafting plus AI coaching. Pro adds auto-draft (replies waiting when you open Gmail), batch replies, and Prompt Lab for version-controlling your prompts. Teams adds a shared persona and seat-level analytics.

    ForthWrite is not for everyone. If you just need quick replies and tone does not matter, Gemini is free and already in your inbox. ForthWrite is for people where tone does matter: client communication, relationship-driven threads, external correspondence where sounding off costs something real.

    Disclosure: I am the founder and use it daily. Happy to answer questions in the comments.

    ๐Ÿ Competitors: Jace.ai, Fyxer, Mailmeteor
    ๐Ÿ‘ Pros:    Drafts land inside gmail and outlook; no copy-pasting from a chat window|Voice matching is on the free tier, not paywalled behind paid plans|No api key, no credit card to start; free tier runs on a server-side proxy|Learns from every edit you make before sending; drafts improve over time|Full keyboard flow: alt+shift+d to draft in any thread, no mouse required|Byok on paid plans, 9 providers supported, keys encrypted at rest|Web compose at forthwrite.ai works without installing the extension at all
    ๐Ÿ‘Ž Cons:    10 free drafts/week is enough to evaluate, not enough for a heavy inbox|Auto-draft, batch replies, and prompt lab all require the pro tier|Early-stage product; fewer third-party integrations than mature inbox tools|No mobile app: the extension and add-in are desktop-only (chrome on web, or the outlook desktop add-in)
