Microsoft Outlook VS ForthWrite

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.

Voice matching from your real sent mail, not templates
Recipient-aware drafts that adapt to who you are emailing
Prompt Lab for version-controlling and A/B testing your persona prompt

Works in Gmail and Outlook on the web, plus a standalone browser widget
Training data export and full data portability

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.

Questions & Answers

As answered by people managing Microsoft Outlook and ForthWrite.

Which are the primary technologies used for building your product?

ForthWrite's answer:

Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

I built ForthWrite to fix generic AI email, and I still use it every day

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.

👎 Cons: 10 free drafts/week is enough to evaluate, not enough for a heavy inbox|Auto-draft, batch replies, and prompt lab all require the pro tier|Early-stage product; fewer third-party integrations than mature inbox tools|No mobile app: the extension and add-in are desktop-only (chrome on web, or the outlook desktop add-in)

Gryphmail completely gone???
It seems like there might be an issue for the UofG site that had the direct link to GryphMail. However, this is not the only way to access your school email. You can go to Outlook and sign in through there with you @uoguelph.ca address — this method works and I was able to access my GryphMail today. Source: about 3 years ago
Email activation
If you've paid your confirmation deposit your email should be created (it can sometimes take 2-3 days). If you've activated your identikey you should be able to log in at https://outlook.live.com/owa/. Source: over 3 years ago
Whats your favourite app that can work as a calendar and also effectively time-block out tasks?
In** 2013** the company I worked for decided that everyone needed to move to Microsoft. We all started to use Outlook and the rest of the Office suite. I really liked the Outlook calendar on the desktop as I could schedule tasks and calendar items (with a little tweaking). Unfortunately, that did not translate to mobile. So I began using paper printouts of my day to stay on task whenever I was away from my PC. Source: over 3 years ago
Power BI Training
You also need a Power BI subscription for some of the labs. You can setup a free Microsoft 365 E5 trial here. Pro Tip: Don't use your real email address when setting up the trial. Create a free dummy email here. That way you can setup another free trial using a different dummy email address once the free trial runs out. Source: almost 4 years ago
is there a way to get just excel and not get 365??
It’s free with the free version of Outlook. Kinda bare bones but works for most functions. Https://outlook.live.com/owa/. Source: almost 4 years ago
