The useful part of a file is that you can return to it. Ask it something today, something else in six months, and it answers from the same chart both times. You do not need to build a personal knowledge system before your first question.

It is written for the assistant, not for you

Open the file and the top is plain English; below that is a dense block of coded rows. That is deliberate. Compacting the chart data lets an assistant hold the whole chart in view while it answers, instead of a fragment — which is exactly what makes the answers join up rather than contradict each other. You are not missing anything by not reading it: everything in there is said back to you in plain words when you ask.

Begin with one question

  1. Attach the file to a new chat and say hello. It will ask you three short things and start reading.
  2. Choose one area rather than asking for everything at once.
  3. Mention the actual decision in front of you, and its date, if there is one.
  4. Ask why whenever an answer surprises you — it can show its reasoning on request.

Try this prompt: “Using only this file, explain what it says about my work in plain language. Separate what is computed from what is interpretation, and say plainly if something is not in the file.”

A file gives context, not infallibility

An assistant can invent a citation, skip a caveat or treat a traditional interpretation as a fact. Supplying a document is a way to make answers easier to check; it is not a guarantee of correctness. Ask it to identify missing information and verify important answers yourself. Medical, legal and financial decisions need appropriate evidence and qualified help.

Keep a simple local notebook

Obsidian stores notes as Markdown files in a local vault. Keep your chart file there alongside separate notes for your questions and your own observations. Ordinary folders and a text editor work just as well. There is a step-by-step setup guide if you want one.

Keep the original file unchanged. In a separate note, record the date, the question, the source passage and what you learned. Label personal observations as observations; do not quietly rewrite them into the original reading.

You can build this yourself

If you enjoy research, collect calculations with their settings, read sources and organise your own notes. Astrodai’s value is the prepared, structured chart file—not exclusive access to an AI or a requirement to buy a subscription. Paid AI tools are not automatically more accurate, and any service’s upload and privacy settings deserve a check before you share personal data.

Already have your file? Here is how to use it on your phone or computer. Still deciding, see what the whole chart decodes before choosing a file. For the calculation side, start with why free charts can disagree.
