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.

  • 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

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.

CloudShell features and specs

  • Integrated Environment
    CloudShell provides a fully integrated development environment directly within your browser, including access to Google Cloud resources, pre-installed Google Cloud SDK, and other useful tools.
  • Convenience
    Because it's browser-based, there is no need to install or configure anything locally, which can save considerable setup time and eliminate environment inconsistencies.
  • Security
    Operating within Google's infrastructure can add layers of security, including secure connection to cloud resources and less risk of exposing local machines to vulnerabilities.
  • Access to Project Resources
    Directly connects to Google Cloud resources associated with your account, making it easy to manage and deploy applications within your cloud environment.
  • Scalability
    Seamlessly scalable environment that can handle different workloads without performance degradation.
  • Persistent Storage
    CloudShell offers persistent storage, allowing users to save their work and configurations, which are available in future sessions.
  • Pre-installed Tools
    Includes a range of pre-installed tools, such as git, gcloud SDK, and language libraries, enabling efficient development and deployment workflows.

Possible disadvantages of CloudShell

  • Resource Limits
    CloudShell has usage limits, including limited disk space and CPU, which may not be sufficient for all types of workloads, particularly resource-intensive tasks.
  • Inactive Use Timeouts
    Sessions that are inactive for a period of time may be automatically terminated, which can disrupt ongoing work.
  • Dependency on Internet Connection
    Being a cloud-based solution, a stable internet connection is required. Any disruption in connectivity can hamper development and deployment processes.
  • Latency Issues
    Depending on your geographical location, there may be latency issues which can affect performance and response times.
  • Limited Customization
    While CloudShell provides many pre-installed tools, users have limited control over the environment compared to a locally managed development setup.
  • Paid Subscription Needed for Extensive Use
    Beyond the free tier, extensive usage of CloudShell resources may incur additional costs, which can add up depending on the scale and nature of the tasks.
  • Learning Curve
    New users who are not familiar with Google Cloud's ecosystem may face an initial learning curve to fully leverage CloudShell's capabilities.

Questions & Answers

As answered by people managing CloudShell 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.

    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)
