Generative UI infrastructure for AI products
Thesys is frontend infrastructure for AI products, built around a Generative UI API and Agent Builder for teams that want AI interfaces to go beyond text. The product is positioned as a way to create interactive, real-time UIs that adapt to context and user intent.
The site shows two related ways to use the platform: build with the C1 API, or use Agent Builder to create and deploy no-code agents. Those agents can respond with charts, forms, cards, dashboards, slides, and reports, and can be embedded into an existing product or launched as a standalone experience.
Core capabilities
Data and tool connections
Connect files, apps, databases, business data, and other tools so the agent can use real context when responding.
Behavior control
Define instructions, guardrails, and workflows to shape how the agent behaves and what it can do.
Multiple deployment surfaces
Deploy agents as standalone apps or embed them in a product, dashboard, or internal tool.
Brand and personality customization
Customize colors, themes, typography, layout, and voice to match the product experience.
Team and access controls
Work with team permissions, SSO, RBAC, workspace-level access, and authentication controls on production plans.
Practical use cases
Data analytics agents
Create agents that surface metrics, drop-offs, trends, and summaries from business data so users can act on the output instead of reading a static response.
Reporting workflows
Generate weekly updates, client reports, business reviews, slides, and summaries from live data for recurring internal or client-facing workflows.
Website assistants
Add a website copilot that answers visitors from site content and can be embedded quickly using the Website Assistant template.
Operational agents
Build internal or customer-facing agents for revenue, finance, product, or operations work, including dashboards, charts, and decision-support views.
Embedded product experiences
Embed an interactive agent into an existing product as a side panel, copilot, or full-screen surface with controlled behavior and branding.
Pros and Cons
Pros
- Supports interactive outputs such as charts, forms, cards, tables, slides, and reports.
- Can be used without code through the Thesys interface, while still offering an API for more control.
- Offers multiple deployment options, including standalone apps and embedded experiences.
- Provides team-oriented features such as workspace permissions, SSO/RBAC, and access controls on production plans.
- Has a free entry point and published pricing for teams that want to estimate usage.
Cons
- Some advanced deployment, security, and identity controls are limited to higher-tier or enterprise plans.
- LLM usage is billed separately on many plans, so overall cost depends on model usage as well as Thesys usage.
- The source material is strongest on product positioning and pricing, with fewer workflow details for integrations beyond the examples listed on the site.
FAQ
What is Agent Builder by Thesys?
Agent Builder is a no-code platform for building and deploying AI agents that return charts, forms, cards, tables, and other interactive UI instead of plain text. The source says you can connect data, define instructions, and deploy the agent as a standalone app or embed it in an existing product.
Who is it for?
The source describes it as a fit for product teams, founders, growth and ops teams, and anyone who wants users to act on top of their own data rather than just read text answers. It is also positioned for teams building AI products and interactive frontends.
Do I need to write code?
No. The product page says you can build, customize, and deploy entirely from the Thesys interface. It also says every agent is available through the C1 API if you want more control later.
Where can I deploy an agent?
You can deploy an agent as a standalone web app on a Thesys URL or embed it as a copilot, side panel, or full-screen experience inside an existing product. The site also says the same agent can run on multiple surfaces.
How does pricing work?
Pricing is usage-based. The site says you start for free and pay for what your agents generate, including the charts, cards, and forms they create, with full details on the pricing page.
