Free Tier Value
This free tier is genuinely usable for small projects: it includes 10,000 messages, 500 guide active users, and 500 AI agent credits every month, plus the core workflow and delivery features. The cheapest paid plan is Starter at $250/month, and the free allowance is roughly 20% of that plan’s headline message volume, so a fair buyer-facing estimate is about $50/month. It resets monthly and does not require a credit card to get started, but the caps keep it well below the paid tier.
