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

MarcoApp.io's answer
We allow all providers to be connected โGmail, iCloud, Outlook, etc. It's easier and faster than Gmail, but it costs less than a third of what Superhuman charges.
Plus, we will never sell your data, unlike others.
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.
MarcoApp.io's answer
Beautifully designed, easy to use, fast and it doesn't break the bank.
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.
MarcoApp.io's answer
Individuals who are willing to pay for an email client instead of having their data harvested.
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.
MarcoApp.io's answer
We wanted something as nice as Superhuman but that would allow me to connect all of my email accounts, not only Gmail and Outlook. So we built it.
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.
ForthWrite's answer:
Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API
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.

Yes, Marco does this (disclaimer, I'm the solo founder): https://marcoapp.io Contacts populate alongside email threads in search results. If you click on a contact, it will take you to a dedicated contact screen with every thread you've ever had with that contact, as well as every attachment they've ever sent you. - Source: Hacker News / 4 months ago
I'm Isaac. I've been building Marco (https://marcoapp.io) for about a year now. It's a cross-platform email client built in React Native with Expo, and I want to share the journey because it's been one of the hardest things I've ever built. - Source: dev.to / 5 months ago
The deeper issue here isn't about Antigravity specifically. It's that email is most people's de facto digital identity. Every password reset, every 2FA recovery, every account verification flows through it. When a company can revoke access to your email over a ToS violation in a completely unrelated product, the stakes are disproportionate. The fix is surprisingly straightforward: own your domain, use a provider... - Source: Hacker News / 5 months ago
Yeah, Gmail's "implementation" of IMAP is essentially unusable. They basically force consumers to use their proprietary API. We're building a cross-provider, cross-platform email client, and literally had to build special cases for all Gmail actions: https://marcoapp.io The upside is that it's fast... The downside is that it's NOT IMAP! - Source: Hacker News / 6 months ago
Check us out, we support Outlook and any other possible IMAP/OAuth provider. Cross platform, offline-first, and instant syncing: https://marcoapp.io. - Source: Hacker News / 8 months ago
