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.

Possible disadvantages of Todo.txt

    Todo.txt does not provide built-in cloud sync; users must implement their own solutions for cross-device synchronization.
  • Limited Built-in Features
    Todo.txt lacks advanced features found in specialized task management apps, such as reminders, notifications, and integrations.
  • Manual Management
    Users must manually edit and manage their tasks, which can be cumbersome compared to apps with graphical interfaces.
  • No Native UI
    There is no standalone graphical user interface; interaction is typically through text editors or command-line interfaces unless third-party apps are used.
  • Potential for Clutter
    Without a structured approach, the plain text file can become cluttered and harder to manage over time.

Questions & Answers

As answered by people managing Todo.txt 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.

    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)

  • A todo.txt shared by a human and AI agents: why plain text beat a SaaS board for my workflow
    I maintain a fleet of small OSS projects. The cross-cutting "what do I do next" list used to live in my head, then in a SaaS board, then nowhere useful. What finally stuck is embarrassingly low-tech: a single todo.txt in todo.txt format, plus a few dozen lines of dependency-free shell and Python around it. - Source: dev.to / 20 days ago
  • Ask HN: Who Uses a Todo.txt?
    I've gone full circle at least two or three times in my life when it comes to todo apps. Where I end up every time I tried all apps and processes is a todo.txt file, based on the http://todotxt.org file format. Now AI agents happily contribute to it as well :-). Is anyone else in that boat? - Source: Hacker News / 3 months ago
  • A comprehensive Sublime Text plugin for managing todo.txt files
    I built this plugin because I'm a huge fan of todo.txt files. Just plain text, no databases, no complex formats, no vendor lock-in. And pairing that simplicity with Sublime Text's blazing speed helps me tremendously with keeping my ADHD in check. If you want to learn more about the todo.txt format, you can check: http://todotxt.org/. - Source: Hacker News / 9 months ago
  • Ask HN: What kind of TUI would you use if it existed?
    Ooooh... You just gave me an idea :). A TUI for http://todotxt.org/. That way, there's no lock-in and people can easily use their existing todo.txt to try the TUI. I'm looking for a TUI idea to explore Ratatui, so maybe this is it right here! - Source: Hacker News / 9 months ago
  • I tried every todo app and ended up with a .txt file
    There is a format called todo.txt that works follows very readable syntax (like your own example) and has some minimal bells and whistles if you want it to: http://todotxt.org/ As an alternative: I started using org-mode 5 years ago and have never looked back. - Source: Hacker News / 12 months ago
