Quick Copy

Quick Copy lets you duplicate a past record to today — handy for recurring expenses.

How to open

Workflow

1. A modal opens showing records from the last 14 days (auto-deduplicated).
2. Search or filter by category.
3. Click "Copy" to write the record to today's note as-is, or "Edit" to modify first.
4. Your today's daily note opens automatically.

iOS: Back Tap shortcut

1. Install the community plugin Obsidian Advanced URI.
2. Create a Shortcuts action that opens: obsidian://advanced-uri?vault=VaultName&commandid=coin-memo:quick-copy
3. Go to Settings → Accessibility → Touch → Back Tap and assign the shortcut.

Bill Screenshot Import

Screenshot from WeChat / bank app → Shortcuts OCR → write to bill.md → run command to auto-import

Workflow

Supported screenshot types

Merchant auto-classification

Open Settings → Bill Import — Merchant Auto-Classification. One rule per line:

merchant_keyword=category_keyword=description

Example:

豆磨坊=cy=买豆腐
麦当劳=cy=麦当劳
盒马=gw=买菜
物业=jf=物业费

• Merchant keyword: matched via substring (no exact match needed).
• Description: optional; if omitted, the description field in the dialog is left blank.

💡 Run an import once without configuring mappings first — the dialog shows the actual OCR merchant text, which you can then use as the key.

Triggering the import

Commands

Open the command palette with Cmd/Ctrl + P:

Advanced URI format: obsidian://advanced-uri?vault=VaultName&commandid=coin-memo:<command-id>

Batch Reclassify

Use case: many records are imported via screenshot OCR and default to #cy. You need to bulk-correct categories based on the description text.

How to open

Click the "Batch Reclassify" button in the tracker view toolbar, or run the command from the palette. It opens in a new tab so it doesn't disrupt the current view.

Workflow

1. Add a rule: Click "+ Add Rule" and fill in the note keyword and target category.
2. Preview: Click "Preview" to scan all daily notes and show matching records grouped by rule.
3. Select: All records are selected by default; uncheck any you don't want to change.
4. Execute: Click "Execute" and confirm — changes are written to the files.

Rule fields

Example: note contains maner → change category to 悦己奖励 (yj)

Auto-classify

When the "Auto" checkbox is enabled, the rule runs silently every time you open the tracker view:

• Only processes records from the last 7 days, so historical data is untouched.
• If the target category is already correct, the file is not modified (preserves timestamps).
• Shows a notification: "Auto-classify complete: X records updated."

Date range filter

Enable "Date range filter" to limit manual preview/execution to a specific date range, preventing accidental changes to older records.

Export

Export PDF

Click "Export PDF" in the tracker view, choose a date range, and export. The PDF includes a summary, category totals, and detailed records.

Export Markdown

Click "Export MD" to generate a Markdown-formatted expense report.

FAQ

Q: No records showing up? Check that your daily notes are in the configured folder, filenames follow YYYY-MM-DD.md, and the record format is correct.

Q: How do I add a new category? Click the "Configure Categories" button in the tracker view.

Q: Where is my data stored? All data lives in your Obsidian notes (daily note files + config.json) — fully local.

Q: What if bill.md gets deleted accidentally? It is only deleted after you confirm the import or when parsing fails. Check the developer console (Cmd+Option+I) for [bill-import] logs if needed.

Q: OCR merchant name doesn't match the actual name? Use the text shown in the import dialog to configure your merchant keyword — OCR may produce slight errors.

💡 Tip: The hardest part of tracking expenses isn't the method — it's consistency. By integrating bookkeeping into your daily notes, recording spending becomes a natural extension of journaling.
