Trajectory says where a theme is going, not just how big it is. Every night, Annsa compares each theme's last 7 days of signals against the 7 days before and labels what changed — Accelerating, Emerging, Declining or Gone quiet. A steady theme wears no badge; quiet is information too.
01Where a theme is heading
02The four labels
| Label | What it means |
|---|---|
| Accelerating | Signals arriving at least 20% faster than the week before |
| Emerging | Too new to trend — fewer than 3 signals, or from fewer than 2 accounts |
| Declining | The pace has dropped to under 80% of the week before |
| Gone quiet | The signals stopped arriving |
03Where you see it
On the priority row, as a badge with the account count behind it — "Accelerating · 6 accounts." Inside the ranking explanation, with the week's percentage change. And in Radar, where a moving theme carries its pace: "accelerating · 4 signals/day."
04A spike is not a trend
One loud day looks identical to a real shift until you compare windows. Measuring this week against the week before — with the account spread beside it — is what separates "three people hit the same bug on Tuesday" from "this is genuinely gathering pace" — commit a sprint to the second, not the first.
05Recomputed nightly
Trajectory refreshes every night, so Monday's read reflects the weekend. It never re-ranks the list on its own — it's evidence beside the rank, and what you do with a declining theme stays your call. An accelerating theme does raise its hand, though: a notification says signals are up this week, so a real shift never waits for you to look.
06What does Accelerating mean in Annsa?
Signals on that theme are arriving at least 20% faster than the week before — this week measured against last week, recomputed nightly. The badge carries the account count too, so you can tell one noisy customer from a genuine spread.
