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

  • 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.

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.

Tatem features and specs

  • Beautiful and intuitive design
    Tatem features a sleek, visually appealing interface that is modern and well-crafted, making task and project management feel enjoyable rather than cluttered. The UI is designed with attention to detail, drawing praise for its aesthetics.
  • Native Apple ecosystem experience
    Tatem is built as a native macOS and iOS app, offering smooth performance, fast load times, and deep integration with Apple platforms including keyboard shortcuts, gestures, and system-level features that web-based alternatives cannot match.
  • Flexible project and task management
    Tatem supports multiple views (list, board, calendar) and offers flexible ways to organize tasks with projects, tags, priorities, and due dates, making it adaptable to various workflows for individuals and small teams.
  • Combines calendar and task management
    Tatem integrates calendar and task management into a single app, allowing users to see their schedule and to-dos in one unified view. This reduces the need to switch between separate calendar and task management tools.
  • Fast and responsive performance
    As a native application rather than an Electron or web-based wrapper, Tatem is notably fast and responsive, providing snappy interactions and quick navigation that enhances daily productivity workflows.

Possible disadvantages of Tatem

  • Limited to Apple platforms
    Tatem is currently only available on macOS, iOS, and iPadOS, which means users on Windows, Android, or Linux are excluded. This limits its usefulness for cross-platform teams or individuals who work across different operating systems.
  • Relatively new with evolving feature set
    As a newer entrant in the productivity space, Tatem may lack some advanced features found in more established tools like Todoist, Asana, or Notion. Some features users expect may still be in development or on the roadmap.
  • Subscription pricing model
    Tatem uses a subscription-based pricing model which can feel expensive over time compared to one-time purchase alternatives, especially for individual users or small teams evaluating it against free or cheaper task management options.
  • Limited integrations with third-party tools
    Compared to mature project management platforms, Tatem currently offers fewer integrations with popular third-party services like Slack, GitHub, Zapier, or other enterprise tools, which can be a limitation for teams with complex workflows.
  • Not ideal for large team collaboration
    Tatem is primarily designed for individuals and small teams. It may not scale well for larger organizations that need advanced permissions, reporting, resource management, or enterprise-grade collaboration features.

Questions & Answers

As answered by people managing ForthWrite and Tatem.

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.

Tatem's answer:

Tatem strives to be more: accessible, in terms of usability and pricing, flexible, providing options for customization, modern, as it was founded in 2023, and intelligent, using AI to power the product and enhance the overall experience.

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.

Tatem's answer:

Tatem is a next-gen, intelligent email client built for speed. Leveraging AI, we help users take control of their inbox and get through emails faster.

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.

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.

    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
