Kady

Kady is a free, open-source AI research assistant for scientists who want to carry out analyses and review evidence on their own computer. You describe the task in plain language, and it can inspect files, write and run analysis code, search literature, and produce figures or reports. It uses the MIT license.

Projects, conversations, notebooks and results stay in ordinary local folders; K-Dense doesn't host or store them. Model choice determines what leaves your machine. Local Ollama models keep model requests on your hardware, while hosted models receive the material needed for each request directly. Kady also works with OpenRouter, your own API keys and supported subscriptions, including ChatGPT, Claude and GitHub Copilot. K-Dense Web is a separate paid, hosted research agent.

Its scientific skills and guided workflows cover fields including bioinformatics, chemistry and clinical research. Specialist agents can handle statistical review, citation checking or literature synthesis in parallel, and you can keep several chats and projects running. You can inspect generated code, redirect the work or stop a run.

A lab notebook records hypotheses, methods, decisions and linked results, with exports and Methods drafts for papers. The workspace previews scientific files such as molecular structures, sequence alignments and medical images alongside tables and Jupyter notebooks. It also includes a LaTeX editor with PDF previews and AI edits you can accept or revert. Web search works without an additional account.
