What does Cossistant do?

Cossistant is an AI customer support agent built specifically for SaaS products that use React or Next.js. Instead of being a separate chat widget, it lives directly inside your app and learns how your team handles support. You can add it with a single npm command, and it starts answering questions almost immediately. The idea is simple: when a customer asks something the AI doesn't know, it asks your team for the answer. You answer once, and Cossistant remembers it for next time.

What makes Cossistant stand out is how it learns on its own. It crawls your documentation, resources, and past conversations to build a self-updating knowledge base. It also comes with pre-built integrations for tools like Linear (to log tickets), Stripe (to check subscriptions), and Cal.com (to book calls). If you need something custom, you can connect your own APIs. You're also in control of the agent's personality — you can set the prompt, the model, and the tone to match your brand.

Cossistant is best for small to medium SaaS teams that want to handle support without hiring a full-time team. Founders, support engineers, and developers can set it up quickly and trust that it will get better over time. It's especially useful for handling common questions, covering overnight hours, and freeing up your team to focus on harder problems.
