What is Conversation API?

Conversation API is a managed backend service that eliminates the complexity of building stateful AI chat features. Instead of wrangling SDKs, databases, and infrastructure just to support conversations and memory, you get a simple API that handles all chat data storage for you. You only need to keep a conversation_id — everything else is managed automatically. Built by the team at Amarsia after watching builders get stuck on AI chat infrastructure instead of focusing on their actual product.

Who it's for

• Solo builders who want to add AI chat to their app without learning backend infrastructure or managing databases
• Low-code creators who need stateful conversation memory but don't want to set up servers or configure SDKs
• Product teams that need to iterate quickly on AI prompts and chat flows without waiting on backend development cycles

Key features

Automatic conversation memory

Every chat interaction is stored and managed server-side. You pass a conversation_id and the API handles the rest — no database setup, no schema design, no data migration scripts to write.

Zero infrastructure management

There is no backend to provision, no servers to configure, and no deployment pipelines to maintain. The entire chat infrastructure runs on Amarsia's platform with a 99.9% uptime SLA.

Fast prompt iteration

Because the infrastructure layer is abstracted away, you can rapidly test and refine prompts without touching any backend code. This turns what used to be multi-day cycles into minutes of work.

Simple integration for any stack

The API works with any HTTP-capable environment — web apps, mobile apps, or backend services. You don't need to install heavy SDKs or manage complex dependencies.

What stands out

"The only platform that turns your AI sprints into minutes."

This isn't just about saving setup time — it's about fundamentally changing how you build AI features. Most chat APIs still require you to manage state, handle persistence, and deal with scaling. Conversation API removes all of that so you can focus entirely on the conversation design and user experience. The sandbox plan is free forever with 10,000 assistant runs per month, meaning you can build and test without any upfront commitment.

Worth checking out if…

You're building any application that needs AI chat with memory — whether it's a customer support bot, an AI tutor, a personal assistant, or a collaborative tool. If you've ever spent more time configuring databases than designing conversations, this API is built for you. It's especially valuable for low-code builders and solo developers who want professional-grade AI chat without hiring a backend engineer.
