Introduction

Brixel is a platform for creating AI agents called Builders. Each Builder is an agent you interact with through a chat interface, designed to handle real workflows end to end.

Why Brixel is different​

Brixel’s uniqueness comes from how it provides tools (in the LLM sense) to the agent. In Brixel, these tools are called Tasks. Every task follows a shared contract and can be combined safely, which makes the whole system composable.

Task types​

  • Actions
    Monolithic, ready-to-use tasks (e.g., "Send an email").
  • Artifacts
    Visual tasks that introduce human interaction or display results directly in the chat.
  • Tools (Brixel)
    Compositions of tasks (e.g., "Download the Word document and convert it to PDF"). A tool can include other tools and executes like code.
  • Variants
    Tasks customized by a user to change their parameters.
  • Plan Generators
    Brixel’s orchestration intelligence. They reference many tasks and generate a dynamic execution plan from a user’s request. They can also be used directly as tools (in the LLM sense) inside a Builder.

Knowledges (context for Builders)​

Builders can access Knowledges to be more relevant in conversation and execution:

  • Abilities
    Instructions tied to tasks that explain how to use them.
  • Documents
    Files transformed into embeddings for contextual retrieval.
  • Memories
    An evolving memory of user preferences, projects, and habits (if enabled).

Scale and composability​

Because of this architecture, a Builder can trigger and combine 1,000+ tools to solve real tasks end to end.

Brixel is a platform for building unique agents and a chat experience with advanced interactions.
