How do I turn my reading highlights into blog post ideas?
Short answer
Collect highlights with a note on why each mattered, then look for passages from different sources that make the same point. That overlap is a post. Lumen's Spark does this automatically: it reads only your highlights and suggests titled ideas with outlines and cited sources.
Step by step
- Highlight with intent and add a one line note.
- Group reading for one piece in a collection.
- Run Spark, keep the ideas that ring true, copy the outline into a draft.
Good to know
Pair Spark with the radar: if a topic you keep circling is also trending this week, that is a good time to publish.

Does Spark write the post for me?
No. It suggests the angle and outline from your own words; you write it.
