Not a website builder

Yuan builds visual AI agents

01

Native AI assistant

What you get isn't a chat box — it's a web app with an Agent fused in, one that can read the app's data and call its operations.

The Agent weaves into the UI in many forms — reading on-screen data, calling the operations you defined, writing results back to the page. Build an AI Go app, and after you place a stone the Agent thinks, plays its move against you, and explains the reasoning behind it.

02

Sessions

Every app comes with sessions: each trip, each review keeps its own data and AI memory, fully separate.

Unlike an ordinary web app, every Yuan app carries the notion of a session that holds the state and AI memory of each use. Build a financial-report analyzer and one session maps to one company's report — return to its earlier state and AI context any time.

03

Build it in a sentence

Describe it in plain words; Yuan decides whether you need data tables, charts or an AI assistant — and publishes it for you. No tech skills required.

Apps come with a database, file storage, charts, a canvas and more built in — but you never pick them by hand. Just describe what you want in your own words and Yuan designs and builds it for you.

04

Ding!

Can't quite describe it, and edits keep missing the mark? Hit Ding! and the AI takes over autonomously — it works out your intent and builds the result for you.

Ding! puts the Yuan Harness Agent into high gear: it re-reads your conversation and the current app, diagnoses the problem itself, then makes and verifies the fix — no need to explain again. You just wait for the Ding!, like sliding cookies into the oven.

05

Connect to external systems

Connect your apps to external data and services through Skills or MCP connections — send email, fetch market data, reach your team's systems.

Skills are reference packets you author — good for domain knowledge or a private API. MCP connections plug into ready-made services (Resend email, Alpha Vantage market data) — just add your key. An HR specialist could build a dashboard from an internal-data Skill (self-hosted deployment coming soon), or have an app send notification emails via MCP — no engineering help needed.

06

Scheduled runs

Let an app run a task by itself every day — fetch fresh data each morning and tidy it into a table, with no one opening it.

Connect external data, then set a daily morning task: the app goes online to pull the data, has AI organize it, and writes it into your table. New tasks start off; once you switch one on it runs on schedule in the background (higher plans allow more tasks at once).

07

Themes & publishing

Swap between visual styles in one click, with multilingual support; publish the moment you're happy.

Keep an app private for yourself, share a link with friends, or make it fully public so everyone can see what you built.
