18. Save content ideas into one clean inbox

Help me design a content idea inbox automation.

Places ideas come from:
[notes app, saved posts, DMs, email, voice memos, screenshots, links]

Where I want ideas saved:
[spreadsheet, Notion, Airtable, task app, or another place]

What each idea should include:
- Raw idea:
- Source:
- Topic:
- Audience:
- Possible format:
- Next action:

Please give me:
1. The simplest workflow.
2. The trigger for each input source.
3. The fields to save.
4. A weekly review checklist.
5. A prompt that turns one saved idea into a draft.
6. The automation tool that fits best and why.
