Agent Builder by Thesys

Definition: Agent Builder by Thesys is a no-code AI agent development platform enabling users to create dynamic, UI-generating AI assistants. It falls under the technical category of generative UI tools, leveraging large language models (LLMs) to transform user queries into interactive visual outputs like charts, forms, and reports.
Core Value Proposition: It eliminates the need for complex workflows or engineering expertise, allowing users to build AI agents that autonomously reason, respond with rich interfaces, and connect seamlessly to data sources—accelerating deployment of customer-facing copilots or internal tools.

Generative UI Engine:
- How it works: Uses proprietary C1 API technology to dynamically render charts, cards, forms, and slides based on real-time data analysis. Unlike static chatbots, it interprets intent to generate interactive elements (e.g., converting Google Sheets data into visual charts).
- Technologies: Integrates LLMs for intent parsing and React-based component generation.
No-Code Agent Customization:
- How it works: Users upload files (PDFs, docs), connect databases (Google Sheets, APIs), or input URLs, then define agent behavior via natural language instructions (tone, guardrails). Style customization includes brand-aligned themes and color schemes.
- Technologies: Drag-and-drop UI with prebuilt templates and CSS/JS injection for embedding.
Multi-Source Data Integration:
- How it works: Supports unstructured data (Google Drive, web content) and structured sources (databases, spreadsheets). Agents auto-sync with connected resources to generate real-time insights (e.g., visual summaries from folders).
- Technologies: OAuth-based connectors and file-parsing algorithms for PDFs, CSVs, and docs.

Pain Point: Replaces text-only chatbots with interactive AI experiences, solving user frustration with passive, non-actionable responses. Addresses the high development cost of building dynamic UIs for data-driven applications.
Target Audience:
- SaaS founders embedding website copilots for customer support.
- Marketing teams creating AI-powered report generators.
- Non-technical business users (e.g., e-commerce managers) deploying data analyzers.
Use Cases:
- Turn help docs into conversational guides with clickable cards.
- Auto-convert sales data into shareable slides.
- Embed live analytics agents in dashboards for real-time user queries.

Differentiation: Unlike workflow-based tools (Zapier) or text-centric AI (ChatGPT), Agent Builder generates dynamic UI components (charts, forms) without predefined logic. Competitors like Gamma or Perplexity lack embedded, brand-customizable agents.
Key Innovation: Intent-driven autonomy—agents independently determine response paths using boundary-defined reasoning, eliminating rigid scripting. The C1 engine’s low-latency rendering enables sub-second UI generation.

What is Agent Builder by Thesys?
Agent Builder is a no-code platform for creating AI agents that respond with interactive UI components like charts, forms, and reports—not just text. Users connect data sources, customize behavior, and publish agents in minutes.
How does Agent Builder pricing work?
Thesys uses usage-based pricing: costs scale with generated outputs (e.g., charts, cards). A free tier is available, with credits added as agent usage grows.
Can I embed Agent Builder in my website?
Yes. Publish agents as live links or embed them via HTML snippets for seamless website integration, enabling real-time user interactions.
What data sources work with Agent Builder?
Supports Google Sheets, databases, PDFs, web URLs, and cloud storage (e.g., Google Drive). APIs connect to tools like n8n for advanced workflows.
Is coding required to use Agent Builder?
No. The no-code interface handles agent creation, customization, and deployment. Developers can optionally extend functionality via the C1 API.
