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
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.

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.
MergeLoom's answer:
Mergeloom is the only ticket to code automation that runs on your own infrastructure and enables you to stay in complete control.
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.
MergeLoom's answer:
Choose MergeLoom if you want AI coding speed without handing control of your codebase to a vendor black box. MergeLoom runs on your own infrastructure, works with your existing tools, applies the same repo rules and prompts every time, validates code before review, and keeps runs auditable. You get 24/7 ticket-to-PR automation while keeping security, workflow, model choice, and human approval under your control.
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.
MergeLoom's answer:
MergeLoom is built for engineering teams that want to adopt AI coding safely at scale.
The primary audience is engineering leaders, CTOs, DevOps/platform teams, and senior developers in SaaS or software-heavy companies who have backlogs of tickets, bugs, maintenance tasks, and feature work, but need control over security, code quality, workflow, validation, auditability, and AI provider choice.
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.
MergeLoom's answer:
MergeLoom started as a personal project to solve a real frustration: AI could write useful code, but using it reliably across tickets, repositories, and team workflows still felt messy and hard to trust.
The goal was to move beyond one-off prompting and build a repeatable ticket-to-code workflow: the right context every time, proper guardrails, validation before review, auditability, and execution that stays on your own infrastructure.
MergeLoom exists because AI coding should not mean losing control of your codebase, workflow, or engineering standards.

MergeLoom uses a self-hosted worker architecture with integrations across common engineering tools and AI providers.
Primary technologies include:
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.
