Build AI agents that reason dynamically and respond with charts, cards, forms, slides and reports. No workflows. No code. Just connect your data, add instructions, customize style, and publish and share with anyone or embed on your site.
Hey folks, Parikshit here, co-founder of Thesys. 👋
Today, we’re launching Agent Builder 🚀
A no-code agent builder to create truly agentic AI apps that respond with interactive UI like charts, forms, cards, slides, and reports, not plain text.
No code. No workflows. No frontend work.
________
⛔️The problem:
Modern AI agents aren’t workflow scripts anymore.
They reason, adapt, and decide. Tools like Claude Co-Work show this clearly.
But most agents are still text-in, text-out.
They answer questions, then stop.
Users still interpret results, build slides, create reports, or take action.
________
❇️ The solution:
Thesys Agent Builder lets you create fully functional AI agents in minutes.
You define intent and guardrails.
The agent decides how to respond and what interface to generate.
They can return:
📊 Charts and dashboards from your data
📝 Forms users can fill and submit
🧩 Cards, tables, and interactive components
📑 Slides and reports ready to share
________
🛄 The steps:
Get started in 3 steps. No code.:
1️⃣ Connect your data
Files, URLs, databases, or tools via MCP
2️⃣ Customize your agent
Add instructions. Set tone, style, and behavior.
3️⃣ Test and Share it
Publish with a link or embed it on your website.
Your agent goes live instantly.
________
✳️ The possibilities:
What you can build :
📈 Analytics agents for visual insights
🤝 Website copilots for guidance and support
💰 Sales agents that improve conversions
🛒 Ecommerce copilots for discovery and comparison
All without writing code or managing UI.

Under the hood, Agent Builder is powered by C1, our Generative UI engine that handles UI generation, orchestration, and runtime, so AI apps actually help users get work done.

The maker mentioned moving from regenerating charts per turn to "live charts where data can be refreshed." thats a fundamentally different architecture problem, stateless generation vs stateful component lifecycle. How is C1 handling component identity and diffing between turns today?
You mention C1 handles UI generation and runtime under the hood that’s super interesting.
From a builder perspective, I’m curious: is the rendering primarily client-side, server-driven, or hybrid?
And when generating something like a multi-series chart during a live conversation, how do you keep the experience responsive?
Really excited about the idea of LLMs returning structured, interactive UI instead of just text.
The pivot from developer API to no-code agent builder is a smart distribution move, but I'm wondering how you handle the tension between the no-code audience and the c1 api developer audience are these the same buyers or are you splitting focus?
How do you see Generative UI evolving compared to traditional static dashboards in the next year?
How does the No-code builder handle complex logic or multi-step workflows compared to the C1 API?"
This is interesting because it shifts the problem from “better prompts” to better outputs. Generative UI feels like the missing layer between LLMs and real products — text is rarely the final interface users want. Curious how you’re handling state + re-renders when responses evolve over time.
Great product guys! Good job on that. Helps people ship 'smarter' AI easy. Best of luck with the launch!
This looks super clean. Congrats on the launch, definitely going to try it with my next project.
The "respond with UI instead of text" approach is exactly what conversational AI needs. I'm curious about how UI state is managed during multi-turn conversations - when a user modifies a previously generated chart or form, does C1 perform incremental updates on the existing component or regenerate from scratch? Also, is there support for preserving partial UI state when the conversation context shifts?
This is interesting. Generative UI instead of static text feels like the natural next step for LLM-based apps.
A lot of “no-code agent” tools break down when you need real integrations, multi-step interactions, and production requirements—what did you deliberately *not* build first (channels, auth/multi-tenancy, exportability, approvals), and how did you decide those tradeoffs?
