Independent project

A Personal Life
Operating System.

My long-running effort to bring local AI, agent workflows, retrieval, knowledge graphs, automation and human approval into one practical system.

Privacy and public work

A private system.
A public foundation.

The private system works with personal information that must remain private. Personal Life OS Core shares a smaller, sanitized, MIT-licensed foundation so others can inspect the ideas, tests and engineering approach without exposing private data or infrastructure.

Privacy and human control are central to what I want the system to become. The educational lessons are meant to be useful beyond my own setup.

Start with suitable material.

Choose information you are comfortable and permitted to share. Name the task and what a useful result must preserve.

Ask for a bounded piece of help.

A draft, explanation or checklist can support your work. A request to draft something is different from permission to send or publish it.

Keep the decision with a person.

Examine the answer, check sources when they matter, and choose what to keep, change or reject. Prompt wording does not replace actual tool permissions.

Inspect the finished result.

Check the document, message or other result against your purpose. A completion message reports an outcome; your inspection checks what is actually there.

Select a step to explore the idea. This is an explanatory graphic, not a live model or a measured system workflow. With scripts off, all four explanations remain visible.

Purpose before automation

Decide what useful work looks like and what the person needs to understand.

Evidence and review

Keep the source material, check the result and leave uncertainty visible.

People remain involved

Keep consequential decisions and the choice to publish or act with a person.
