How we review
AI App Stacker is an independent, automated review site. Every product is researched, scored, and written up by AI research agents — and the whole catalog refreshes every day so prices and capabilities don't go stale.
The process, every day
Fully automatedTwo scheduled jobs run each morning. The first refreshes the facts; the second writes the review. Neither involves a human editor — which is the point, and also why we're upfront about how it works below.
Research & data refresh
An AI research agent (Claude, with live web search) looks up each product and verifies its current pricing, key features, pros and cons, and — for hardware — technical specs against primary sources. It records the most authoritative source URL it used and the date it checked.
A 0–10 score
From that research, the agent assigns each product an overall score out of 10, weighing capability, value for money, and how it stacks up against the alternatives in its own category. Scores move over time as products — and their competitors — change.
Re-ranking the lists
Category rankings and the featured “most important” lists are rebuilt from those scores — top-rated by score within software and hardware. No product can pay to rank higher; placement follows the score, full stop.
The written review
A second agent — our AI App Stacker Editorial — writes a balanced, hype-free review and one-line verdict for each product, drawing on the refreshed facts. A review is rewritten whenever the underlying data changes, so the words never drift from the numbers.
How to read a score
0–10Scores are relative to a product's own category, not the whole market — an 8.5 voice tool and an 8.5 GPU both mean “excellent for what it is,” not that they're equivalent. As a rough guide:
| 9.0+ | Category leader — best-in-class, hard to fault. |
| 8.0+ | Excellent; a top pick for most people. |
| 7.0+ | Solid and worth considering for the right use case. |
| <7 | Has real trade-offs — read the pros and cons closely. |
Comparing products fairly
Apples to applesWithin each category, features are normalized to a shared vocabulary — so “text-to-video,” “API access,” or “4K output” read identically across every product that has them. That's what makes the side-by-side compare matrix actually line up instead of listing each vendor's marketing phrasing.
Independence & honesty
No stringsAffiliate links never affect scores or rankings. AI App Stacker may earn a commission when you buy through some of our outbound links — that's how the site is funded — but commissions play no part in how a product is researched, scored, or ordered.
We also want to be clear about the trade-off of an automated site: reviews and scores are generated by AI from publicly available information. We show each product's source and the date its data was last verified (the catalog was last refreshed on June 8, 2026). Treat the reviews as a fast, consistent starting point — and confirm anything critical (especially current pricing and plan limits) on the vendor's own site before you buy.
