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.

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.

  • Auto-draft: replies waiting in Gmail before you open your inbox
  • 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
  • BYOK support: bring your own API key for Claude, OpenAI, Grok, Mistral, and more
  • 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.

Questions & Answers

As answered by people managing Koofr 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.

  1. very good for backup of mobile photos

Best Free Cloud Storage for 2024: What Cloud Storage Providers Offer the Most Free Storage?
Koofr is a small cloud storage company from Slovenia that recently upgraded its free storage plan. You now get 10GB of storage for free, but thereรขย€ย™s no achievement or referral program to expand this further. Because of its location in the European Union, all of Koofrรขย€ย™s customers are protected by the GDPR, and the service scores well for both security and privacy.
Best Cloud Storage Services for Linux
Koofr is a cloud storage provider thatโ€™s a good option for Linux because of its Linux GUI desktop client. They have an online version, desktop and mobile versions, browser extensions, and more. The best thing about Koofr is that you can connect Google Drive, Dropbox, and OneDrive to your Koofr account and search through all files from all accounts from Koofr.

Furthermore, Koofr is particular about privacy and security. The tool doesnโ€™t track your activities and file transfer is secured using Secure Sockets Layer (SSL) and Transport Layer Security (TLS) encryption.
The Best Google Drive Alternatives for 2022: Ditching Big Brother
Overall, Koofr is a very good cloud storage service as a private alternative to Google Drive. However, if youรขย€ย™re transitioning from a free Drive account to Koofr, youรขย€ย™ll be disappointed by the lack of free storage, and if youรขย€ย™re used to paying a bit for a Google One subscription, youรขย€ย™ll find Koofrรขย€ย™s price tag a bit steep. Thatรขย€ย™s why Koofr takes last place on this...

Sharing lets you email a link, copy and paste it or share directly to Facebook, Twitter, Reddit or Tumblr. You canรขย€ย™t password-protect links when sharing to social networks, but you can otherwise. Thereรขย€ย™s an option to make links expire, too. Unlike many services, including Dropbox, Koofr even provides those content control features for free users. Read our Koofr review...

ForthWrite Reviews

  1. curtisboortz
    ยท Founder at ForthWrite ยท
    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.

    ๐Ÿ Competitors: Jace.ai, Fyxer, Mailmeteor
    ๐Ÿ‘ Pros:    Drafts land inside gmail and outlook; no copy-pasting from a chat window|Voice matching is on the free tier, not paywalled behind paid plans|No api key, no credit card to start; free tier runs on a server-side proxy|Learns from every edit you make before sending; drafts improve over time|Full keyboard flow: alt+shift+d to draft in any thread, no mouse required|Byok on paid plans, 9 providers supported, keys encrypted at rest|Web compose at forthwrite.ai works without installing the extension at all
    ๐Ÿ‘Ž 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)

  • The Difference Between Downloading and Streaming
    At Koofr[1] one of the most requested features was an option to prevent downloading files from public links. We didn't want to lie to our users so we added a "Hide download button" option because that's the only thing you can do. You can hide the download button but you can never really prevent the download. [1] https://koofr.eu. - Source: Hacker News / about 1 year ago
  • Need new cloud service
    If you're not too far from Europe* then Koofr might come pretty close to your idea. 1TB "lifetime" 160 US$ ATM (less if you find a coupon they accept at checkout, many generic Stacksocial-Codes worked in the past). I'm a happy "lifetime" user of them, only disadvantage I discovered so far: They do not store creation date/time of folders, only of files. Source: over 2 years ago
  • Does Koofr offer zero knowledge encryption out of the box?

    Koofr offers cloud storage that you can access over the web, with the Koofr apps, or via protocols like WebDAV or rclone โ€“ perfectly suitable for syncing or backup. Koofr works great with Cryptomator, which encrypts your data before uploading. We are an official reseller of Koofr. Source: over 3 years ago
