Private control plane for AI agents

What it solves

Friday provides a private, local control plane for AI agents to prevent the common pitfalls of autonomous agents, such as "hallucinating" completion of tasks, executing risky commands without permission, or poisoning personal memory with incorrect facts. It acts as a neutral referee that manages multiple AI models from different vendors, ensuring the user remains the ultimate authority rather than relying on a single provider's ecosystem.

How it works

Friday operates as a local "kernel" that manages a loop of routing, execution, verification, and memory. Instead of being a model itself, it uses a "Bring Your Own Key" (BYOK) approach to route tasks to various cloud AIs (like Claude, Codex, or DeepSeek).

The system follows a strict workflow:

  1. Route: Selects the most appropriate AI for the specific step.
  2. Execute: Runs the task, pausing for human approval if the step is deemed risky.
  3. Verify: Requires a "proof receipt" to confirm a task is actually finished, rather than trusting the AI's word.
  4. Remember: Proposes new facts as candidates for the user to confirm before they are permanently stored in memory.

Who it’s for

It is designed for users who want to leverage powerful AI agents for complex, long-term goals but require strict governance, privacy, and cross-vendor flexibility without giving up control to a cloud provider.

Highlights

  • Local-First Governance: Keys, data, and memory are stored locally on the user's machine.
  • Evidence-Backed Completion: Tasks cannot be marked as complete without a verifiable receipt.
  • Human-in-the-Loop: Risky actions require explicit manual sign-off and cannot be rubber-stamped by the AI.
  • Cross-Vendor Routing: Dynamically distributes work across different models to optimize for cost and capability.
  • Tamper-Evident Audit: Uses a hash-chained audit log to track every agent turn.
