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.
SuppDoc.io is a free, evidence-based supplement tool. Take a 2-minute quiz, or describe your goal in plain English, to get a personalized supplement stack tailored to your sleep, training, diet, and budget. Already taking supplements? Paste your current stack and your bloodwork and SuppDoc audits it for interactions, redundancies, and dosing, then suggests fixes. Every ingredient comes with an evidence-graded guide and the number of real clinical studies linked straight to PubMed, so you can verify the source yourself. With 200+ ingredients, a documented interaction checker, and a free stack audit, SuppDoc stays neutral: no fake reviews and no house brand to push. Free, no signup.
ForthWrite SuppDoc.ioForthWrite'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.
SuppDoc.io's answer:
SuppDoc.io is free and stays neutral: it doesn't sell its own pills, so there's no incentive to push any specific product. Every recommendation is evidence-graded, and the number of real clinical studies behind each ingredient links straight to PubMed so you can verify it yourself. It's also one of the few tools that tells you when you don't need a supplement, and that audits a stack you already take for interactions, redundancies, and dosing.
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.
SuppDoc.io's answer:
Most supplement advice online is either hype or paywalled. SuppDoc.io is free, needs no account or clinician, and grades every recommendation by the actual evidence, linking the clinical studies so you can check them yourself. Unlike practitioner platforms such as Fullscript, you don't need a provider to use it; and unlike static review sites, it personalizes a full stack to your goals and then audits it for interactions, redundancies, and dosing. It also has no house brand to push.
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.
SuppDoc.io's answer:
Health-conscious adults who take (or are considering) supplements and want evidence over hype: people optimizing sleep, energy, focus, stress, or training, those making sense of bloodwork, and anyone who already takes several supplements and wants to check them for interactions, redundancies, and correct dosing. It's built for beginners and the supplement-curious alike โ no clinician or signup required.
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.
SuppDoc.io's answer:
SuppDoc.io was built out of frustration with supplement advice that is either hype ("this pill fixes everything") or locked behind a paywall, while the boring-but-important parts get skipped: what you shouldn't combine, the dose that was actually studied, and what's just marketing. The goal is a free, honest tool that grades the evidence transparently, links the studies, says when a supplement isn't worth it, and never sells its own pills.
ForthWrite's answer
Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API
SuppDoc.io's answer:
SuppDoc.io is built with Next.js (React) and TypeScript, uses Supabase (PostgreSQL) for its database and authentication, and is deployed on Vercel.
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.
