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

  • 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 ResearchRocket.app and ForthWrite.

Why should a person choose your product over its competitors?

ResearchRocket.app's answer

To match Research Rocket you'd pay for UserTesting, Optimal, Marvin, a stats tool, and a slide deck, five subscriptions that never talk to each other. Research Rocket replaces all of them with one connected platform, and adds what they lack: real inferential statistics (t-tests, chi-square, ANOVA) and built-in neuromarketing that shows why people decide, not just what they did. Every study ends with a clear recommendation and decision and risk analysis, so research leads to action. And you can own it with one-time lifetime access instead of paying monthly forever.

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.

What makes your product unique?

ResearchRocket.app's answer

Most research tools only do one piece. UserTesting handles usability, Optimal handles card sorts and tree tests, Marvin stores interviews, and none of them run real statistics or tell you what to actually do next.

Research Rocket is the only platform that brings the entire research workflow into one place, quantitative and qualitative, surveys, usability studies, card sorts, tree tests, moderated interviews, and participant recruitment, and adds two things no other research tool has: real inferential statistics (t-tests, chi-square, ANOVA) and built-in neuromarketing that reveals why people decide, not just what they did.

And it doesn't stop at collecting data. Every study ends with AI-assisted synthesis, a clear recommendation, and decision and risk analysis, so your research actually drives the decision instead of sitting in a slide deck.

One tool, from evidence to decision, with a one-time lifetime option instead of another monthly subscription.

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.

What's the story behind your product?

ResearchRocket.app's answer

Research Rocket started with a frustration every researcher knows.

I loved the work, finding the signal, understanding why people do what they do. But I was doing that work across a dozen disconnected tools. A survey platform here, a repository there, analysis in a spreadsheet, insights in a slide deck. Each one good on its own, and none of them talking to each other. So an insight that should have led straight to a decision would get copied, pasted, reformatted, and slowly lose its power. Too often, great research ended up sitting in a deck while the decision got made on a gut feeling anyway.

I kept thinking the same thing. The work is already great. It just needs to connect.

So I built Research Rocket: one place that brings the whole journey together. Surveys, real statistics, usability testing, qualitative analysis, neuromarketing, and a research repository, all connected, and every study ends with a clear, evidence-backed decision.

It's the tool I always wished I had, built for the people who do the work, so their insights finally lead to better decisions instead of getting lost between tools.

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.

How would you describe the primary audience of your product?

ResearchRocket.app's answer

Research Rocket is built for the people who make product decisions and need evidence to back them.

That includes: - UX and product researchers who want to run studies and synthesize insights without juggling multiple tools - Product managers and product owners deciding what to build or launch next - Founders and startup teams trying to reduce the risk of expensive product bets - Innovation and growth teams evaluating concepts, features, and roadmap priorities

It fits solo researchers running their first study all the way up to product teams that need a shared repository and a clear, evidence-backed decision at the end.

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.

Which are the primary technologies used for building your product?

ResearchRocket.app's answer

React, TypeScript, Vite, Tailwind CSS, shadcn/ui, Supabase, PostgreSQL, Stripe, TanStack Query, D3.js

ForthWrite's answer:

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

    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)
