notion-im-helper（Notion IM 助手）

Notion IM Helper

通过消息自动同步内容到 Notion。支持日记、笔记、待办、想法、问题、链接、摘抄 7 种类型。

Environment Variables

• NOTION_API_KEY - Notion Integration Token
• NOTION_PARENT_PAGE_ID - Target Notion Page ID (32 chars)
• NOTION_QUOTES_PAGE_ID (optional) - Separate page for quotes

Setup

1. pip install notion-client
2. Set env vars: NOTION_API_KEY and NOTION_PARENT_PAGE_ID
3. Authorize integration on Notion page (··· > Connect to)

Usage

When the user sends a message matching a trigger pattern, execute the corresponding script:

python scripts/record.py record --type {type} "{content}"
python scripts/record.py heading --level {1|2|3} "{text}"
python scripts/record.py divider
python scripts/record.py list --kind {bullet|number} "{items}"
python scripts/record.py toggle "{json}"
python scripts/record.py image [--caption "text"] "{file_path_or_url}"
python scripts/record.py caption "{content_to_append}"
python scripts/record.py undo
python scripts/check_config.py
python scripts/summary.py {monthly|quote}

Trigger Rules

Content types (prefix → type):

• 日记: / 今天: / riji: / d → diary
• 笔记: / 学习: / note: / n → note
• 待办: / todo: / t → todo
• done: / 完成: / √ → done
• 想法: / 灵感: / idea: / flash: / 闪念: / i → idea
• 问题: / 疑问: / q: → question
• 摘抄: / quote: / qu: / z → quote
• 链接: / link: / url: / l → link
• 图片: / photo: / img: / p → image
• caption: / 说明: / 补: → caption (append to last entry)

Formats:

• * text → H1 heading
• ** text → H2 heading
• *** text → H3 heading
• > text → quote block
• --- → divider
• - text → bulleted list
• 1. text / 2. text etc → numbered list
• toggle: title + subsequent - / -- / --- lines → toggle block

Commands:

• 月报 / monthly → extract current month records for summary
• 摘抄 / 随机摘抄 → random historical entry
• 搜: xxx / search: xxx → search records by keyword
• 撤回 / undo → delete last batch of blocks (within 5 min window)
• 配置检查 / check config → verify config

Smart detection (no prefix, AI infers):

• Pure URL → link
• Starts with YYYY-MM-DD → diary
• Contains [ ] or 【 】 → todo
• Default → idea

Caption — two distinct uses:

caption: / 说明: / 补: has two different behaviors depending on context:

1. Caption Append (standalone — no image/link in message)

When the user sends caption: as the primary prefix of a message with no images or links, it appends the content to the last callout on the Notion page:

• caption: 补充一个角度 → appends "↳ 补充一个角度" as a child paragraph inside the last callout
• 说明: 这个想法还有一个延伸 → same behavior
• 补: 对了还有一点 → same behavior

Implementation: Write content to .pending_content.txt, then run python scripts/record.py caption.

Visual: The appended paragraph is prefixed with ↳ to distinguish it from the original content.

2. Caption Separator (with image/link in message)

When the message contains images or links, caption: acts as a separator between diary content and image/link caption:

• OPPO园区很好 caption: 园区环境 + 3 images → last image gets caption "园区环境", diary "OPPO园区很好" synced separately
• Without caption:, all text is diary/idea content, no caption on images

IMPORTANT: The AI must check whether the message contains images or links to determine which caption behavior to use.

Metadata

Scan the LAST line for metadata:

• #关键词 → tag
• /p:项目名 → project
• Remove metadata from content before passing to script

Batch & Undo

• Multi-line messages: each format line (heading/quote/divider/list) becomes a separate block, sent in a single API call
• Undo within 5 minutes: deletes all blocks from the last batch
• Undo after 5 minutes: deletes only the last single block
• Day separator: a divider is auto-inserted when the last record is from a different day

Output Protocol

Scripts emit standardized output prefixes:

• OK|message → success, relay success message to user
• ERROR|CONFIG → guide user to set up Notion integration
• ERROR|AUTH → invalid API key or page not authorized
• ERROR|RATE_LIMIT → tell user to wait
• ERROR|NETWORK → tell user to retry later

Always run check_config.py first on first use. Never modify or delete existing Notion blocks.

Image Upload

• Supports local file paths (e.g., C:\Users\photos\img.jpg) and HTTP URLs (e.g., https://example.com/photo.png)
• Local files are uploaded to Notion servers via the File Upload API, then attached as image blocks
• URL images are referenced directly as external image blocks
• Optional --caption flag to add caption text to the image
• Max file size: 5MB (Notion API limit)
• Supported formats: jpg, jpeg, png, gif, webp, bmp, svg

Image + Text Sync Rules

When user sends both image and text in one message:

1. Parse text: split by caption: / 说明: keyword (if present) — this is the Caption Separator mode

- Before caption: → diary/idea/note content (synced as callout) - After caption: → image caption (added to last image via --caption)

1. Upload images: first N-1 images without caption, last image with --caption
2. Sync text: write diary/idea content to .pending_content.txt, then record.py record --type {type}

Examples:

• OPPO园区很好 caption: 园区环境 + 3 images → last image gets caption "园区环境", diary "OPPO园区很好" synced separately
• 这张图有意思 + 1 image → no caption keyword, so no caption on image, "这张图有意思" synced as idea
• 2 images only → just upload both, no caption, no callout

IMPORTANT:

• Image and text are always separate operations — image via record.py image, text via record.py record
• Do NOT put image and text in the same command
• When user sends image only (no text or just "同步到notion"), upload the image as-is using record.py image. Do NOT transcribe/OCR the image content into a callout

Link + Caption

Same caption: pattern works for links:

• 链接: https://example.com caption: 好文章 → bookmark with caption "好文章"
• Without caption:, just a plain bookmark card (Notion auto-fetches title)

Long Content Auto-Split

• ≤2000 chars: Single callout (most entries)
• >2000 chars: Auto-split into multiple callouts at paragraph boundaries (e.g., 3-4k chars → 2-3 callouts)
• Metadata (tags/projects) only added to the last callout
• AI should write the entire content to .pending_content.txt at once — do NOT manually split into multiple calls

Best Practices for AI Callers

• Content passing: Always use .pending_content.txt (write file → run script). Never pass content via command-line args (PowerShell $ expansion issues).
• Image passing: Copy to .pending_image.jpg, the script auto-detects and cleans up.
• Type inference: If user says "notion" or "同步" without specifying type, infer from content:

- Starts with caption: / 说明: / 补: → caption (append to last entry) - Contains "日记"/"今天" → diary - Contains URL → link - Image only → image (use record.py image) - Default → idea

• Undo: Use record.py undo — respects 5-min batch window, deletes all blocks from last batch.
