Deepseek has shifted to my general go to, this being one of the factors. Most likely claude is making up some small details to reinforce what it thinks is right or optimal, but generally still right.

What this evidence does not show yet

To reach Payment-backed we still need:

  • a first-hand payment statement — either someone naming what they already pay, or 2 more statement(s) with a specific amount they would pay (we have 0)
  • renewed mentions — the recent trend is below the promotion bar

No first-hand payment statement is on record here, so this page carries no pricing suggestion. A price with no payment evidence behind it is a guess wearing a number.

Scoring summary

Evidence confidence = strength × evidence volume × source diversity × payment × competition × trend × 10. Counts use independent content items; only first-hand pain, current spend, explicit willingness to pay and concrete feature requests affect the score. Repeated posts by one author are discounted. Scoring and status changes follow deterministic rules.

“Payment-backed” means first-hand payment evidence exists in the record. It does not mean the business is worth building. “Fading” is a recency tag shown alongside any evidence level, not a lower level. Read the full methodology.
