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 Lose it! 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 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.

  • Feeling discouraged
    I have tried crash diets in the past and have never felt this good or this energetic. I'm going to keep going like this until I'm at my goal weight. I gained 60 lbs from taking this antipsych med called zyprexa (it's known for extreme weight gain fast but I was like I'd rather be mentally ok than fit and thin right now so I'm basically trying to reverse it. I use loseit.com to track my cals and exercise works... Source: over 3 years ago
  • no motivation
    Follow that guide and that timing, and you'll be able to start putting some data around your diet. Start with your regular, normal food. My favorite tool for this is now-better LoseIt! Over MyFitnessPal which has been on the decline for years. Source: over 3 years ago
  • [23] I gained about 10 kgs in the past year. starting from zero knowledge on weight loss any advice? pics are from 2021 dec and last week (2023 mar)
    You can use a TDEE calculator to work out approximately how many calories your body is using per day. You need to eat in a deficit of around 15-20% of your TDEE to see decent weight loss. You can use an app like Lose It! To track your food intake and see how many calories you're eating. People are notoriously bad at underestimating the calories that they consume so I really recommend you do some calorie tracking.... Source: over 3 years ago
  • Is 1200 calories actually enough?
    At 1200 kCal/day you'll certainly lose weight, but it probably won't be safe... My older-but-similarly-sized spouse gets about 1600 (to lose weight) if she sits on the couch, so being active will certainly bump that up. We use an app called lose it to track both food and exercise and it seems to do a decent enough job for me and her. So your 1200 may be fine if you're a couch potato, but it sounds like you need... Source: over 3 years ago
  • Progress tracking app?
    I use LoseIt. I've used it since I started on phentermine back in 2007, so it has a lot of historical data for me. It has a good barcode scanner and remembers your most frequently added items so once you put in a meal, you can just click into that section when adding foods and it will have the full list of ingredients from meals there.
