## Summary

K-Dense BYOK is a free, open-source AI research assistant designed for scientists. It runs locally on a user’s own computer and integrates with any chosen model, whether hosted or local. The tool provides a structured workspace, workflow templates, and a **Living Lab Notebook** that logs actions via a hash-chained system to prevent model overclaiming—tracking what the agent does rather than relying on its assertions.

Developed by K-Dense AI, the project emphasizes reproducibility by storing data, code, and results in a researcher-controlled folder. It outperformed two managed platforms in a benchmark of 20 interdisciplinary prompts, scoring higher in both scientific quality and execution. The notebook’s immutable logs and environment records (including software versions) distinguish it from competitors. The code is licensed under MIT and available on GitHub.

## Key points

- K-Dense BYOK runs locally on a user’s computer and integrates with any model, hosted or local
- Hash-chained notebook logs agent actions to prevent overclaiming and ensure reproducibility
- Outperformed two managed platforms in a benchmark of 20 interdisciplinary research prompts

## Why it matters

This tool lowers barriers for independent research by combining model flexibility with auditability, addressing trust issues in AI-generated outputs.
