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.

  • Voice matching from your real sent mail, not templates
  • Recipient-aware drafts that adapt to who you are emailing

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.

Next.js features and specs

  • Server-Side Rendering (SSR)
    Next.js supports SSR, allowing pages to be rendered on the server-side before being sent to the client. This results in improved SEO and faster initial page loads.
  • Static Site Generation (SSG)
    Enables pre-rendering pages at build time, which can further improve performance and scalability while allowing for dynamic generation when needed.
  • API Routes
    Next.js allows you to build API endpoints directly in the application, simplifying the process of creating back-end services and endpoints.
  • File-Based Routing
    Offers a simple file-based routing mechanism where the file structure maps directly to the appโ€™s routes, making it easier to manage and understand.
  • Automatic Code Splitting
    Automatically splits code at the page level, reducing the initial load time and improving performance by only loading necessary JavaScript.
  • TypeScript Support
    Built-in support for TypeScript, allowing developers to use static type checking and other TypeScript features easily.
  • Developer Experience
    Provides a great developer experience with features like fast refresh, hot reloading, and detailed error reporting.
  • Rich Ecosystem
    Benefiting from the rich ecosystem of the React community and integrating well with other libraries and tools.
  • Internationalization
    Built-in support for internationalization helps developers build multilingual applications with ease.
  • Community and Support
    Strong community and extensive documentation provide ample support and resources for new and experienced developers alike.

Possible disadvantages of Next.js

  • Learning Curve
    The robust feature set of Next.js can present a steep learning curve for developers who are new to React or server-side rendering concepts.
  • Configuration Overhead
    Although Next.js aims for simplicity, complex projects may still require significant configuration and customization.
  • Performance Overhead
    SSR can introduce additional server load and latency compared to static site generators, especially under high traffic conditions.
  • Deployment Complexity
    Deploying Next.js applications that leverage SSR or API routes may be more complex and could require more sophisticated server infrastructure.
  • Vendor Lock-In
    If heavily relying on Next.js-specific features, moving away from the framework to another solution could require significant refactoring.
  • Bundle Size
    Without careful optimization, client-side bundle sizes can become large, negatively affecting the applicationโ€™s performance.
  • Build Times
    For large applications, build times can be significant, impacting the development cycle and deployment times.
  • Dependencies
    Next.js introduces its own set of dependencies and tooling, which might complicate version management and compatibility with other tools.

Questions & Answers

As answered by people managing Next.js 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. Kurslog team
    ยท Working at Kurslog ยท

    Next.js has become the de-facto standard for our frontend engineering team when building modern web applications. The Server-Side Rendering (SSR) and Static Site Generation (SSG) are absolutely essential for our product's SEO strategy and fast indexing.

    The transition to the App Router initially required a paradigm shift for our developers, but it ultimately made our architecture much more scalable. We love that the framework handles the heavy liftingโ€”image optimization, code splitting, and routingโ€”allowing our team to focus purely on business logic. It provides a phenomenal Developer Experience that keeps our deployment cycles fast and predictable.

    ๐Ÿ Competitors: Remix, Nuxt.js, Svelte, Vite
    ๐Ÿ‘ Pros:    Out-of-the-box ssr and ssg for excellent seo|Superb developer experience with zero-config setup|Built-in optimizations for images, fonts, and scripts|Highly scalable routing via the app router
    ๐Ÿ‘Ž Cons:    The app router requires a paradigm shift and learning curve for the team at first|Caching strategies can be tricky to master and debug across a large, dynamic app

    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)
