The Chart History tab shows a product’s weekly movement across Rank, DECA Score, and Mention Rate in its category — the view that separates a one-week spike from real momentum.

Chart History for a ranked product

​
The movement chart

Pick a range — Last 4 Weeks, Last 8 Weeks, or All — and the chart plots DECA Score and Mention Rate week by week across it. On a free account the table shows the last four weeks; Pro shows the full history.

​
The weekly table

Below the chart, every measured week is a row with the exact numbers behind the lines:
  • Week — the collection week.
  • AI Platform — the engine and the exact model version that measured that week (e.g. ChatGPT, gpt-5.6-terra).
  • Rank, DECA Score, and Mention Rate — each with its change from the week before.
Because every row records the model that produced it, you can always tell whether a movement happened within the same measurement conditions or across a model transition.
