Yasumaro Chrome Extension Setup Guide: Auto-Save Web Pages to Obsidian

Yasumaro is a Chrome extension that automatically records browsing history with AI-generated summaries and optionally appends them to Obsidian daily notes. It focuses on pages you actually read by using dwell time and scroll depth thresholds rather than capturing every tab.

Yasumaro Chrome Extension Overview and Main Features

Yasumaro triggers recording when a page is viewed for at least 5 seconds and scrolled past 50%. It extracts content, sends it to your chosen AI provider for summarization, and stores the result locally in SQLite (OPFS). With Obsidian integration enabled, summaries and URLs are appended to a dedicated “ブラウザ閲覧履歴” section in daily notes.

Key features include domain filters (whitelist/blacklist with uBlock Origin import), private page detection with hold queue, master password protection (AES-GCM), FTS5 full-text search supporting Japanese, and manual recording that bypasses duplicate checks. The extension works independently of Obsidian via local SQLite storage.

Installation from Chrome Web Store

Search for “Yasumaro – AI Browsing Logger” in the Chrome Web Store and install. After installation, click the toolbar icon to open the main screen, then the ⚙ icon to access the settings dashboard. Enter your AI provider and API key, then click “Save & Test Connection” to verify. Version 6.0.1 (updated June 23, 2026) supports bilingual UI.

Linking with Obsidian Vault

Obsidian integration requires the Local REST API plugin and an API key. In settings, configure Protocol/Port (typically https/27124), Daily Notes Path (e.g., 092.Daily), and the Obsidian API Key. Once connected, browsing history is automatically appended to daily notes. The extension runs fully without Obsidian using only local SQLite, with export options available later.

Capture and Auto-Save Flow for Browser Pages

1. View page for 5+ seconds with 50%+ scroll depth
2. Content extraction and AI summarization (ad/navigation removal pipeline)
3. Save to local SQLite (duplicate URLs limited to once per day)
4. Append to daily note when Obsidian integration is active
5. Toolbar badge notifications (orange ! for privacy header, blue ◎ for save complete)

Manual recording via the “今すぐ記録” button allows immediate capture, including override for blacklisted domains.

---

Troubleshooting and Limitations

If auto-recording fails, check dwell/scroll thresholds and domain filters. Private pages trigger a confirmation dialog before saving. OPFS-incompatible environments fall back to chrome.storage.local. Use “Test Connection” to diagnose API key issues. Configure max record count and retention period to manage storage.

Comparison with Similar Tools

The official Obsidian Web Clipper is primarily manual with no AI summarization or automatic detection. Yasumaro combines AI summarization and automatic triggers while prioritizing local privacy.

Frequently Asked Questions (FAQ)

Q: Is Yasumaro free to use?

Core features are free. AI provider usage fees apply separately (Groq free tier available).

Q: How good is the saved Markdown quality?

AI summarization removes ads and navigation, producing clean content. It is summary-focused rather than full copies.

Q: Are images and tables saved correctly?

Saving is text-summary centric. Images are referenced by URL; tables are converted to text.

Q: Can I use multiple Vaults?

Yes, by changing the Daily Notes Path per Vault.

Q: Is privacy secure? Where is data sent?

All history stays on-device in OPFS/SQLite. Only summaries are sent to your chosen AI provider. No data is sent to the extension developer.
