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.

FoundStep is a project management tool built for indie developers who keep starting projects but never finish them. It walks you through a structured lifecycle: capture an idea, validate it with a 7-step questionnaire, make a build-or-kill decision, lock your scope, and ship.

Scope locking is the core mechanic. Once you lock your features and todos, nothing gets added without unlocking first. Every unlock requires a written reason that gets permanently logged in your Shame History. You can always cut scope without unlocking, but adding is what costs you. This creates the friction that stops scope creep before it kills your project.

The built-in AI watches your workspace (deadlines, todo completion, lock status, unlock history) and gives you one next action at a time. No dashboards to interpret. Just a single clear directive: finish this todo, lock your scope, or ship it.

When you ship, your project goes to your Harbor, a public portfolio with your ship date, build time, and unlock count. You also get a downloadable Ship Card to share as proof you actually finished something.

FoundStep also generates a Public Wall, a developer portfolio page with your profile, project detail pages, tech stack, milestones, and screenshots. All built automatically from what you ship.

No team features. No Kanban boards. No integrations. Just the constraints that make solo developers actually finish what they start.

Questions & Answers

As answered by people managing ForthWrite and Foundstep.

Who are some of the biggest customers of your product?

Foundstep's answer:

  • Indie developers shipping their first product
  • Solo founders building SaaS tools on the side
  • Developers tired of starting projects and never finishing them
  • Side project builders who code nights and weekends

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.

Foundstep's answer:

I'm a solo developer with 50+ started projects and less than 10 shipped. I realized the problem was never motivation or skill. It was the lack of a system that forced me to validate ideas before building, stop adding scope mid-project, and actually decide when something is done. I couldn't find a tool that did this, so I built one. FoundStep came from my own graveyard of abandoned projects.

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

Foundstep's answer:

Next.js, React, TypeScript, Tailwind CSS, and Node.js. The frontend is built with Next.js 15 using the App Router. The UI uses shadcn/ui components. The backend runs on Node.js with a REST 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.

Foundstep's answer:

Most project tools give you a blank canvas and let you organize however you want. FoundStep does the opposite. It forces you through a fixed lifecycle: validate your idea, decide if it's worth building, lock your scope, and ship. You can't skip steps. If you want to add something after locking scope, you have to unlock it and write a reason that gets logged permanently. That friction is the point. It stops scope creep before it kills the project.

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.

Foundstep's answer:

Tools like Notion, Linear, and Trello are built for teams and give you full flexibility. That flexibility is exactly why solo developers never finish anything. FoundStep removes the flexibility on purpose. It has a 7-step validation questionnaire so you don't build bad ideas, scope locking so you stop adding features mid-build, and a permanent log of every time you broke your own rules. No other tool does this. It's not a better project manager. It's a system that makes you ship.

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.

Foundstep's answer:

Solo developers and indie hackers who start side projects but rarely finish them. People with 10+ repos collecting dust. Developers who code nights and weekends, don't have time to set up complex tools, and need a process that holds them accountable without adding overhead.

    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.
