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 Cosmos Video and ForthWrite.

Which are the primary technologies used for building your product?

Cosmos Video's answer

  • Advanced Video Codec: VP9 with SVC (Scalable Video Coding) - providing superior quality at lower bandwidth
  • Enterprise Infrastructure: Built on AWS, GCP, and Azure for global reliability
  • Security Stack: SOC 2 Type II certified infrastructure with end-to-end encryption

ForthWrite's answer:

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

What makes your product unique?

Cosmos Video's answer

It creates an always-on digital space where teams naturally collaborate without scheduling friction. Through proximity-based calling and presence awareness, Cosmos transforms remote work from transactional meetings into a genuine workplace community. Easily reach out to colleagues with a virtual shoulder tap whenever you need support, eliminating the wait for responses.

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?

Cosmos Video's answer

  • Superior Performance: 10% lower CPU usage than Gather, Kumospace, and Roam - meaning 3x longer battery life and better multitasking
  • Exceptional Audio Quality: 96 kbps studio-quality audio versus competitors' 24-32 kbps
  • Cost Efficiency: It's cheapest in the market, and its space capacity pricing can save organisations over $100,000 annually (e.g., 1,000-member community with 150 peak users pays $742.50/month vs $10,000/month with per-user pricing)
  • Professional Features: True 4K screen sharing at 30fps, SOC 2 Type II certification, GDPR compliance

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?

Cosmos Video's answer

  • Remote teams of 5-150 members seeking to recreate office culture virtually to boost culture and spontaneous collaboration
  • Creative professionals (VFX studios, design agencies) requiring high-quality visual collaboration
  • Educational institutions building engaging online learning communities

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?

Cosmos Video's answer

Cosmos was founded in 2020 by Karan Baweja and Rahul Goyal to solve the fundamental problems of remote work: isolation, meeting fatigue, and lost team culture. They saw colleagues struggling with "working remotely on your own is lonely and isolating" and recognised that "inviting people to meetings for quick collaboration is painful."

Instead of another video conferencing tool, create a virtual office that feels alive โ€“ where you can see colleagues at their desks, walk over for quick chats, and maintain the spontaneous interactions that spark creativity and build culture. Today, Cosmos serves thousands of users across creative studios, agencies, and educational institutions.

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.

Who are some of the biggest customers of your product?

Cosmos Video's answer

  • Tomorrow University
  • Wise
  • Netflix
  • Videns Analytics
  • Workflex
  • Portcast
  • Wing assistant

    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)
