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.
TextCompareo is a free, privacy-first comparison tool. Compare two texts, PDFs, Word docs, Excel sheets, HTML pages, or entire folders and instantly see every added, removed, and changed line โ highlighted word by word. Everything runs 100% locally in your browser. Files are never uploaded to any server, so even sensitive documents stay fully private. No signup, no installation, no limits.

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.
TextCompareo's answer:
TextCompareo runs 100% inside your browser โ your files are never uploaded to any server. Most comparison tools send your data to the cloud, but TextCompareo does all the parsing and diffing locally, so even sensitive documents stay completely private.
It's also multi-format in one place โ compare not just plain text, but PDFs, Word docs, Excel sheets, CSV, HTML pages, and even entire folders. Its parser is framework-aware, so it can pull readable text out of modern JavaScript-heavy pages (Next.js, React, Nuxt.js) that other tools leave empty.
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.

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.
TextCompareo's answer:
Developers, writers and editors, legal and compliance teams, data analysts, translators, students, and QA testers โ anyone who needs to spot exactly what changed between two versions of a document, spreadsheet, webpage, or folder without risking their data on a server.
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.
TextCompareo's answer:
TextCompareo started from a simple frustration: most online compare tools force you to upload your files to their servers โ a real problem when those files contain contracts, private drafts, or confidential data.
We built TextCompareo to do the opposite: run everything in the browser, so your data never leaves your device. From there it grew into a full suite that compares text, documents, spreadsheets, and folders โ fast, free, and private by default.
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.
