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.
Patientree AI is an AI-powered healthcare operations platform designed to simplify and modernize how clinics manage patient engagement, scheduling, billing coordination, and day-to-day administrative workflows. Built from the ground up with Generative AI and automation at its core, Patientree helps healthcare providers reduce manual effort, improve operational efficiency, and deliver a smoother patient experienceโwithout replacing their existing systems.
Healthcare teams often struggle with fragmented tools, rigid workflows, and time-consuming administrative tasks that pull focus away from patient care. Patientree addresses this gap by providing intelligent, adaptable workflows that align with how clinics actually operate. The platform augments current EHRs and practice management systems, enabling automation and insight across scheduling, communication, follow-ups, and financial workflows while maintaining compliance-aware design principles.
Unlike traditional healthcare software that relies on static rules and complex configurations, Patientree uses AI-driven logic to understand intent, adapt to changing workflows, and scale with practice needs. This allows clinics to move faster, reduce errors, and maintain consistency across patient interactions without increasing operational overhead.
Patientree is built using a modern, cloud-native technology stack, including scalable backend services, secure APIs, and AI agent architectures that support intelligent decision-making and orchestration. The platform is designed to be modular, allowing healthcare teams to adopt features incrementally and grow usage over time without disruption.
Founded by engineers with deep experience in enterprise systems and applied AI, Patientreeโs mission is to make advanced healthcare automation accessible, practical, and trustworthy. By combining intelligent automation with human-centric design, Patientree AI empowers healthcare providers to focus less on administration.

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.
Patientree's answer:
Patientree is built as an AI-first healthcare operations platform, not a traditional scheduling or EHR add-on. It combines Generative AI, workflow automation, and compliance-aware design to streamline patient engagement, scheduling, billing coordination, and practice operationsโwithout forcing clinics to replace their existing systems.
Unlike rigid tools, Patientree adapts to how clinics actually work and evolves with their needs.
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.
Patientree's answer:
Patientree stands out by focusing on end-to-end operational intelligence, not just one feature like scheduling or messaging. It offers:
AI-driven automation instead of rule-based workflows
Seamless integration with existing EHRs and practice systems
Built-in compliance awareness for healthcare communications
Faster setup and customization compared to legacy healthcare software
For clinics that want to reduce administrative burden while improving patient experience, Patientree delivers flexibility without complexity.
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.
Patientree's answer:
Patientree is designed for:
Small to mid-sized medical practices
Specialty clinics (primary care, outpatient, telemedicine)
Practice administrators and operations teams
Healthcare founders building modern, AI-enabled workflows
Itโs especially valuable for teams that want automation and intelligence without enterprise-level overhead.
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.
Patientree's answer:
Patientree was created to address a common frustration in healthcare: powerful technology exists, but itโs often fragmented, expensive, or hard to adopt.
After years of building enterprise-grade platforms and AI systems, the team behind Patientree saw an opportunity to bring modern Generative AI and automation into everyday clinical operationsโmaking healthcare workflows smarter, simpler, and more human-centric.

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.
