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.

Stacklite is a calm workspace for solo freelancers tired of juggling 6 different tools just to send one invoice.

Contracts, invoices, time tracking, and client management โ€” all in one place. Free forever.


The Problem

The average freelancer uses 4-7 apps just to run their business. Notion for notes. Toggl for time. Google Docs for contracts. PayPal for invoices. A spreadsheet for clients.

The result? Fragmented, anxiety-inducing admin work that eats into the actual work you freelance to do.

And before you can try most tools that claim to solve this? A sign-up wall. Email. Password. Verify. Choose a plan. By the time you're in, you've forgotten why you came.


The Solution

Guest mode. Open Stacklite and start working immediately. No email. No password. No friction. Your data saves locally. Create an account later if you want โ€” or don't.

Core Features

  • Contract Generator โ€” Professional contracts in under 2 minutes
  • Invoice Generator โ€” Line items, tax calculation, auto-filled from tracked hours
  • Time Tracker โ€” One click to start. Hours flow directly into invoices.
  • Client Management โ€” Every contract, invoice, and time entry linked automatically

Pricing

Free. Not a free trial. Not a free tier. Free forever.

Solo freelancers shouldn't pay a subscription tax just to manage their own business.

Questions & Answers

As answered by people managing ForthWrite and Stacklite.live.

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

Stacklite.live's answer:

Modern web technologies optimized for speed, reliability, and a seamless guest-to-account experience. Built as a web application accessible from any browser without installation.

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.

Stacklite.live's answer:

Guest mode. No sign-up wall, no email verification, no account required. You land on the workspace and start working immediately. Contracts, invoices, time tracking, and client management all connect to each other automatically. Built for solo freelancers specifically โ€” not a stripped-down agency tool.

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.

Stacklite.live's answer:

Three reasons. First, it's free โ€” not a free trial, not a free tier, free forever. Second, guest mode means zero friction to start. Third, it's calm by design โ€” no bloated dashboards, no complex workflows, no weeks of setup. Bonsai costs $19-49/month. HoneyBook doubled their pricing in 2025. Stacklite costs nothing and works in 30 seconds.

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.

Stacklite.live's answer:

Solo freelancers โ€” designers, developers, writers, photographers, and consultants managing 3-15 active clients. People who bill on project or retainer basis and spend too much time on admin instead of actual work. Not agencies, not teams, not enterprise.

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.

Stacklite.live's answer:

Built by a product designer who got tired of switching between 6 different apps just to invoice one client. Toggl for hours, Google Docs for contracts, PayPal for invoices, Notion for client notes. One day the context switching got too painful. So I built one calm workspace that does all of it โ€” and made it free because freelancers shouldn't pay a subscription tax just to manage their own business.

    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.
