RewriteMateForthWrite'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.
RewriteMate's answer:
RewriteMate seamlessly integrates directly into your keyboard, allowing you to refine and enhance your writing without ever leaving your current app. Unlike traditional writing assistants that require switching between applications, RewriteMate works exactly where you're already typing. What truly sets it apart is its customizable AIโyou can adjust the rewriting style to match your personal voice, ensuring your text always sounds authentically like you.
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.
RewriteMate's answer:
RewriteMate eliminates the friction that slows down your writing process. While competitors require the tedious cycle of copying text, switching apps, pasting, editing, and copying back, RewriteMate works instantly wherever you typeโwhether in messaging apps, email, social media, or documents. You maintain complete control over your writing style with customizable settings, and you save valuable time by keeping your entire workflow in one seamless experience.
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.
RewriteMate's answer:
RewriteMate serves anyone who values clear, effective communication on mobile devices. Our core users include professionals crafting important emails and messages, students working on assignments, content creators managing social media, non-native English speakers seeking confidence in their writing, and busy individuals who need to communicate clearly and quickly throughout their day.
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.
RewriteMate's answer:
RewriteMate was born from a simple observation: existing writing tools were creating more friction than they solved. Every time you needed to improve your writing, you had to interrupt your flowโcopy text, open another app, wait for results, then paste everything back. We asked ourselves: why should getting writing help require leaving what you're working on? RewriteMate was built to solve this fundamental problem by bringing AI-powered writing assistance directly into your keyboard, making better writing effortless and instantaneous.

RewriteMate's answer:
RewriteMate is built on Apple's iOS keyboard extension framework, enabling deep system-level integration that works across all apps. We leverage advanced AI language models to power intelligent text rewriting, grammar correction, and style enhancement. The app processes requests efficiently to provide near-instant suggestions while maintaining user privacy and security standards.
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.
