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.

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.
EasySendSMS's answer:
EasySendSMS combines global SMS coverage with enterprise-grade routing and developer-friendly API access. The platform offers direct and premium SMS routes across 200+ countries, real-time delivery reporting, SMPP connectivity, and scalable infrastructure designed for high-volume A2P messaging. Its focus on reliable international routing and competitive pricing makes it suitable for both growing businesses and large-scale senders.
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.
EasySendSMS's answer:
EasySendSMS provides a balance of global reach, competitive pricing, and flexible integration options. Businesses benefit from premium routing, stable delivery performance, REST API and SMPP support, and responsive support for international traffic. Unlike many providers that focus on a single region, EasySendSMS is built for cross-border messaging and global scalability.
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.
EasySendSMS's answer:
EasySendSMS is designed for:
SaaS platforms
Fintech companies
eCommerce businesses
Marketing agencies
Enterprises requiring OTP or transactional messaging
SMS resellers and aggregators
The platform supports both technical developers integrating via API and business users managing campaigns via dashboard.
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.
EasySendSMS's answer:
EasySendSMS was created to provide businesses with a reliable and scalable global SMS infrastructure. As demand for international A2P messaging grew, the platform focused on building strong carrier relationships, optimizing routing quality, and delivering a developer-friendly API. Today, EasySendSMS supports businesses worldwide with dependable SMS connectivity.

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.
