ForthWrite

No. Every paid plan includes "AI Included" by default. We handle all the AI infrastructure and you just write emails. The free tier also gives you 10 AI-powered drafts per week with no setup, no API key, and no credit card. The optional "BYOK" (Bring Your Own Key) toggle is a ~17% discount for users who already have their own OpenAI, Anthropic, Google, or xAI key and prefer to pay that provider directly.

No, and you shouldn't have to. Pick AI Included (the default) and ignore the BYOK toggle entirely. Your subscription covers the AI cost, you'll never see a separate API bill, and every feature works identically. BYOK exists purely as a cost-saver for users who already have an API key from another project. It's a discount, not a better plan.

Feature-for-feature, the two variants are identical. With AI Included, ForthWrite pays the upstream AI provider on your behalf and you pay one flat subscription. With BYOK (Bring Your Own Key), you connect your own API key, pay the AI provider directly for what you use, and earn a ~17% discount on your ForthWrite subscription. AI Included is the right pick for most people; BYOK only saves money if you're comfortable managing an API key and a separate provider bill.

All paid plans start with a 14-day free trial. No charge until the trial ends. After that, your features are available immediately and we'll prorate the difference if you switch plans.

If your drafts don't sound like you within 60 days, we'll schedule a 30-minute call to tune your voice profile together. If it's still not clicking after that, we'll refund everything. No questions, no forms.

Yes. Cancel anytime through your billing portal. You'll keep full access until the end of your billing period, and you can always downgrade to the free plan instead of leaving entirely.

The free plan gives you 10 AI-generated drafts per week with voice matching already included, with no API key or credit card required. Upgrade to Pro when you want unlimited drafts, auto-draft, Prompt Lab, and intent-aware coaching.

The calculator on this page multiplies your hourly rate by the hours you spend drafting email each day, your workdays per month, and a savings rate (default 50%, because ForthWrite speeds drafting rather than clearing your whole inbox). That gives an estimated monthly dollar value you can compare to Pro ($29/mo) or Teams (from $79/seat/mo). After you start drafting, your dashboard tracks a usage-based time-saved estimate you can take to whoever expenses the subscription.

Pro uses a voice profile automatically built from your real sent emails, so drafts pick up your tone, sentence length, greetings, and sign-offs. You can also set a custom persona prompt for specific scenarios.

Every email you send through ForthWrite is added to your personal library. When Pro writes a new draft, it pulls in the most relevant past replies you've sent and uses them as live examples, so drafts get smarter and more "you" over time. (The technical name is RAG, or retrieval-augmented generation, if you want to nerd out.)
