Short answer: this is where AI Life keeps its numbers. Each page below is built from a file you can download, every figure carries a date and a source link, and the method and limits are written next to the data. Prices come only from the maker’s own store, for example the Oura shop and the Eight Sleep shop. I never write a figure from Amazon onto the page.
What data does AI Life publish?
- AI Gadget Price Index: the price each tracked AI gadget shows at its maker’s own store, checked once a day, with the change since a stated baseline date. It answers “what do these cost and which ones moved?”
- Black Friday 2026 AI Gadget Price Drops: which of the same gadgets dropped under their baseline during the sale window, and whether any store raised its own list price first. It answers “were the Black Friday prices real?”
- AI Device Launch Tracker: new AI devices with the maker’s own announcement date, availability date, launch price and the maker’s own words about its AI. It answers “what launched, when did it ship and what does the maker claim?”
How do I use this data?
Every page has a “Cite this page” box with a ready sentence, a CSV download and a CC BY 4.0 license. Credit means a link back to the page and the name Web of Mike. You do not need to ask. If you want one number checked or a store added, email [email protected].
Why do the data pages list prices when the rest of AI Life does not?
The rest of AI Life points you to a live store listing, because a price I typed in last week can be wrong today. The data pages are different: each price is read by a script from the maker’s own store page on a stated day and shown with that day. A price on these pages is a dated observation, not a quote. The reasoning for the rest of the site is on how I evaluate products.
What does the data not cover?
It covers a fixed list of devices that AI Life already reviews, and only where the maker’s store page states a price a script can read. It is not the market. Amazon, Best Buy and other retailers are out, so a lower price at a retailer will not show up here. Start with the AI Life home page for the reviews behind each device, and the deals hub for how I handle sale shopping.
