Brain Vault Capture

A zero-build Chrome extension that captures the active page URL and readable text into an Obsidian Wiki _raw folder.

Install

Open chrome://extensions.
Enable Developer mode.
Click Load unpacked.
Select this folder: extensions/brain-capture.

Use

Find this repo's configured vault path from the command line:

awk -F= '/^OBSIDIAN_VAULT_PATH=/{print $2 "/_raw"; exit}' "$(git rev-parse --show-toplevel)/.env"

Open the extension popup.
Click Choose _raw and select the vault raw folder, usually vault/_raw.
Open any normal web page and click Capture current page.
Or right-click a page and choose Capture page to brain raw.
Or select text, right-click, and choose Capture selection to brain raw.

The extension writes a markdown file named like 2026-06-17-page-title.md into the selected folder.

Promote Captures Into The Wiki

After captures land in _raw/, run the ingest skill from your AI agent:

/wiki-ingest promote my raw pages

The ingest skill will distill the raw captures into proper wiki pages, update the vault bookkeeping files, and delete promoted _raw/ files so they are not processed twice.

What Gets Captured

YAML frontmatter with title, source URL, creation timestamp, and capture metadata.
The page title, URL, optional user note, selected text, and readable page text.
Content is capped at 140,000 characters to keep captures usable for later wiki ingest.
