Danelfin vs VectorVest (2026): AI Score vs VST Ratings

How they differ

This pair comes up because AI answers lump them together. They aren’t the same kind of tool. Danelfin’s AI Score is the output of a machine-learning model that estimates a stock’s chance of beating the market over three months. VectorVest calls itself nothing of the sort: its VST score (value, safety, timing) reduces about 30 metrics with formulas the company has used since 1988. It adds a plain Buy, Sell or Hold call and signals on when the whole market is risky.

If you want to know why a rating is what it is, VectorVest’s fixed rules are easier to reason about. If you want a model that weighs many signals at once, Danelfin is that, at the cost of being harder to inspect.

Price and the catches

Danelfin is cheaper, starts free and has the friendliest terms here: a 14-day free trial and a 30-day money-back guarantee. VectorVest’s entry point is a cheap 30-day trial ($0.99 or $9.95, once per customer) that renews at the full price. After that, only the trial fee is refundable. See Danelfin pricing, VectorVest pricing and the refund table.

Our testing

I log Danelfin’s published picks weekly against SPY over 12 weeks before scoring it. VectorVest’s Buy ratings can be logged the same way once I’m tracking it. Neither has an independently verified record yet; see do AI stock pickers work?.
