Overview

Model, prompt and skills are configurable, with tools for Linear, Stripe and Cal.com.

Best for: React and Next.js SaaS teams wanting an AI support agent inside their own product.
Pricing: Free tier at $0/month, then Hobby at $20/month and Pro at $40/month under a launch promo (list prices $30 and $90); no annual rates are shown.
