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.

Evergreen ILS features and specs

  • Open Source
    Evergreen ILS is open-source software, meaning libraries can freely use, modify, and distribute it. This reduces licensing costs and allows for community-driven development and customization.
  • Community Support
    Being open-source, Evergreen has a strong, active community that contributes to its development and provides support and documentation. This can be beneficial for troubleshooting and enhancing the system.
  • Scalability
    Evergreen is designed to handle large numbers of transactions and manage collections of various sizes, making it suitable for libraries of different capacities, especially consortia.
  • Comprehensive Features
    The system offers a range of integrated modules that cover essential library functions such as cataloging, circulation, acquisitions, and patron management, helping streamline library operations.
  • Customizability
    Libraries can customize Evergreen to meet their specific needs since they have access to the source code. This flexibility can lead to more efficient workflows tailored to the library's requirements.

Possible disadvantages of Evergreen ILS

  • Technical Expertise Required
    Implementing and maintaining an open-source ILS like Evergreen often requires in-house technical expertise or hiring specialized IT services to ensure smooth operation, which can be challenging for smaller libraries.
  • Initial Setup Complexity
    The installation and configuration of Evergreen can be complex and time-consuming, potentially requiring significant technical knowledge and resources to get it up and running.
  • Limited Vendor Support
    Unlike proprietary ILS systems that come with professional vendor support, Evergreen relies on community support, which can be less reliable or slower in addressing urgent issues.
  • Upgrade and Maintenance Responsibility
    Libraries using Evergreen are responsible for managing updates and maintenance, which may require planning and technical skills to avoid compatibility and downtime issues.
  • Steeper Learning Curve
    For library staff, the transition to Evergreen may involve a steeper learning curve compared to other systems, due to its broad feature set and the need for familiarity with open-source principles.

Questions & Answers

As answered by people managing Evergreen ILS 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)

  • Talk to me about your ILS! Who loves their ILS? Who hates their ILS?
    We use PINES which is based on Evergreen, which is open-source. I believe there are vendors you can pay to help you set it up and run it, and there's a volunteer community that will help, too. Of course, this is at the expense of having someone else run it *for* you, but my understanding is that we (Georgia libraries that use PINES) decided to make the software to address limitations in existing ILSs. So, if your... Source: over 3 years ago
