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.

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.

  • 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

  • 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.

Questions & Answers

As answered by people managing Zo Computer 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)

Zo Computer mentions (6)

  • I rebuilt Zo Computer from scratch in 775 lines of Python โ€” here's what stuck and what snapped
    Zo Computer gives you an AI agent, a skills registry, a compute pool, browser automation, file hosting, scheduled automations, and persistent memory โ€” all on a personal server. I wanted to understand every seam, so I rebuilt the whole thing in vanilla Python 3 with no web framework and no Docker. The result is ZoClone: 10 modules, 775 lines, 4 SQLite tables, one ThreadPoolExecutor. This is what the architecture... - Source: dev.to / 2 months ago
  • I rebuilt Zo Computer's seven subsystems in 800 lines of Python โ€” here's the architecture, the tradeoffs, and what I cut
    I've been using Zo Computer as my primary AI workspace for a few months. The piece I kept coming back to wasn't the model โ€” it was the substrate: the agent manager that spawns parallel sessions, the skills registry that auto-loads SKILL.md files, the memory engine that compresses old context, the rrule-based scheduler, the compute pool that turns idle machines into workers, the BYOK client that swaps between... - Source: dev.to / 2 months ago
  • Is anyone actually using OpenClaw?
    I've got a free hosted one from Zo Computer which sends me a daily news summary but I can't say I really use it. https://zo.computer/ if you want to try. They had $100 free credits for the promo code 'clawconlon'. Not sure if that's still going. - Source: Hacker News / 4 months ago
  • Nvidia NemoClaw
    Check out https://zo.computer - we've been doing OpenClaw for nearly a year, it works out of the box, and has hosting built-in. Zo arguably was the inspiration for Peter to create OpenClaw. - Source: Hacker News / 5 months ago
  • 2026 is the Year of Self-hosting
    Great post! Totally agree โ€“ agents like Claude Code make self-hosting a lot more realistic and low maintenance for the average dev. We've gone a step further, and made this even easier with https://zo.computer You get a server, and a lot of useful built-in functionality (like the ability to text with your server). - Source: Hacker News / 7 months ago
