Based on the ideas in Why Helpful Content Gets Forgotten
Step 1
A through-line is the central idea that organizes your entire piece. Answer these four questions to surface yours — the best through-lines usually emerge from the tension between what people assume and what's actually true.
What do most people assume about this topic that isn't quite right? The through-line can be the correction.
If the reader fully absorbs this piece, what changes for them? Name the shift concretely — not "they'll know more" but "they'll stop doing X and start doing Y."
If your outline has multiple sections, steps, or tips — what single principle do they all serve? That underlying principle might be the through-line.
If someone asked your honest take on this topic, what would it be? That instinct is often the through-line hiding in plain sight.
Step 2
Write up to three through-line options. One sentence each. The best ones reframe the topic, not just describe it. Or use the suggest button to seed candidates from your answers above.
Step 3
Pick your strongest candidate and run it through these five checks. Click the right side to toggle: untested → pass → fail.
