Distill notes through progressive summarization

Highlight within highlights — each pass through a note extracts the most essential signal.

Why it works

Raw captures are too dense to be useful in a future working context where time is short. Progressive summarization layers three passes over a note: first highlight the most important sentences; second, bold the most important of those; third, write a brief executive summary at the top. Each pass is done opportunistically — when you return to a note for a real use — so the processing effort is distributed and each refinement is motivated by an actual need.

How to do it

1. Layer 1: when you first save or revisit a note, highlight the sentences that matter most.
2. Layer 2: when you return for a concrete project, bold the most essential of the highlighted phrases.
3. Layer 3: only for the most important notes — write a two- to three-sentence summary at the top.
4. Never refine a note without a reason; process "just in time," not "just in case."

Evidence

Progressive summarization applies the retrieval-practice and spaced-repetition logic that each re-engagement with material at a higher level of processing deepens encoding. The specific three-layer format is Forte’s practitioner innovation; the underlying principle of elaborative processing improving memory is well established. Craik and Tulving demonstrated experimentally that words processed for deeper, more elaborate meaning are retained far better than those processed shallowly — the direct memory basis for why each successive summarization pass strengthens recall. (observational)

Progressive summarization is only worth the investment for notes you actually return to; processing every note to layer three is over-engineering and creates more work than value.

Common mistake

Processing notes proactively ("I’ll summarize everything I read this week") rather than reactively (when you actually need a note for something), turning summarization into a maintenance chore.
