Do I need to sign up for Obsidian? No.

Obsidian is free for local use and requires no account. An account is only for optional services such as Obsidian Sync or Publish. Skip those until the local Business Brain is working.

These are current, privacy-safe screenshots from a disposable copy of this exact Business Brain. Your operating system may use a lighter color theme, but the names and actions are the same.

The only five terms you need

Vault

A normal folder on your computer that Obsidian opens.

Note

A plain-text file ending in .md.

Markdown

Simple formatting such as headings and bullets.

Template

A reusable blank note that tells you what to capture.

Link

A connection from one note to another inside the vault.

Obsidian organizes files. It does not transcribe recordings for you.

Part two · Process one call

Turn one recording into useful memory.

1

Pick one recent call

Choose one sales call, coaching call, client call, work session, or presentation whose outcome you still remember. Do not bulk-import the library.

2

Keep the source and useful note separate

Leave the original recording in its authorized private location. Put its transcript and one verified useful note in 03-Meetings.

3

Verify before you repeat

Check decisions, commitments, owners, dates, numbers, and quotes against the transcript—and the retained recording when the detail matters. Mark uncertainty NEEDS REVIEW.

Keep the literal call checklist beside you

The full guide includes filenames, transcript format, confidentiality guardrails, verification checks, and a bounded AI extraction prompt.

Set the naming rules before note #2

Choose one naming contract for calls, decisions, SOPs, workflows, and operators so people and AI can retrieve the right source later.

Download NAMING-CONVENTIONS.md →

Start with one recent call. Verify it. Then work newest-first. Once five notes are genuinely useful, decide whether automation is worth adding.

Use only recordings you are authorized to retain and process. Keep confidential material inside systems and AI tools approved for that information.
