How many AI tools die? What happened to 2,100 of the tools we listed

This is for anyone who bookmarked an AI tool from a "top 20" roundup a year or two ago and now gets a dead link. Toolio rechecked its own catalog in September 2026, and the short answer is that roughly one in four of the tools it originally listed are gone - shut down, sold off, or replaced by a domain squatter.

Key takeaways

• Of 8,976 tools Toolio originally listed, 6,877 were still reachable as of September 2026, putting the overall disappearance rate at about 23%.
• An automated first pass flagged 3,198 listings as possibly dead. A manual recheck of that group found about 63% were actually gone in some form, and about a third were false alarms - still running, just blocking automated visits.
• "Dead" covers several different endings: an expired domain now for sale, an empty parked page, a domain that now serves spam or gambling content, or simply no response at all.
• Chrome extensions fail in a different way than websites do - a listing in the store gets pulled by the platform rather than a domain going quiet.
• Most of the tools in this check were first listed between July and October 2024, so these numbers describe roughly a two-year survival window, not a tool's total lifespan.

The headline number

Toolio listed 8,976 tools when it built its original catalog. As of September 2026, 6,877 of those were still alive and reachable - a loss of 2,099 tools, or close to 23%. That is not a study or a survey; it is what happened to Toolio's own listings when every one of them was checked again. It says nothing about AI tools in general, only about the specific batch Toolio indexed, most of it gathered in the second half of 2024.

What "failing a check" actually means

Not every one of those 2,099 disappearances came from the same kind of failure, and the raw death count hides an important detail: a first automated pass doesn't reliably tell dead from merely defensive. Toolio flagged 3,198 listings as suspicious enough to need a second, manual look. Here is how that group broke down by what the recheck actually found:

• Website: dead - 1,069. No response at all; the domain is gone.
• Website: parked - 252. The domain resolves to a "this domain is for sale" page.
• Website: empty - 179. The site loads but there is nothing there.
• Website: probably parked - 65. Looks parked but wasn't confirmed.
• Website: hijacked - 17. The domain now serves unrelated spam or gambling content.
• Website: moved (new domain) - 30. The tool is alive, just not where it was listed.
• Website: unsafe - 4. Flagged as unsafe to visit.
• Website: alive - 62, plus website: alive (blocks bots) - 133. Working sites that either passed cleanly or were only rejecting the automated checker.
• Chrome extension: alive - 877, versus chrome extension: removed - 466.
• App store: alive - 9, versus app store: removed - 35.

Add up the categories that mean the tool is actually gone in some form - dead, parked, empty, hijacked, unsafe, plus removed extensions and removed app listings - and that is 2,022 of the 3,198 rechecked tools, or about 63%. Add up the ones confirmed still working - alive, alive-but-blocks-bots, alive extensions, alive app listings - and that is 1,081, or about 34%. The rest, roughly 3%, were ambiguous: probably parked, or moved to a new domain.

The useful part of this breakdown isn't the death count, it's the false-alarm rate. About a third of the listings an automated checker flagged as suspicious were, on a manual look, just fine. A number of tools now actively block automated visitors, which an automated health check reads as "no response" even though a human visiting the same URL gets a working product.

Chrome extensions have their own failure mode

Toolio's original catalog included 1,526 Chrome extensions. Extensions don't go through the domain-parking, hijacking or "for sale" endings that websites do - a browser extension either stays live in the store or gets pulled by the platform, for anything from abandonment to a policy violation to the developer account itself disappearing. Within the group that got a manual recheck, extensions split roughly two-to-one alive versus removed (877 versus 466), which is a meaningfully better survival rate than the standalone websites in the same recheck group, where confirmed-dead outcomes were the largest single category.

Why tools disappear this fast

Toolio's data does not include a reason field, so this section is judgment, not measurement. A large share of the tools that get built and listed during any AI hype wave are thin wrappers around someone else's model API: a chat interface, a prompt template, a Chrome extension that reformats a response. Those are cheap to build and just as cheap to abandon once the novelty, the traffic, or the founder's interest fades. A tool with its own infrastructure, a paying user base, or a company behind it with other revenue tends to survive a slow news cycle; a weekend side project usually doesn't. None of that is unique to AI tools - it is the normal shape of any low-cost software boom - but the volume of listings that came out of 2024's AI tool rush means the die-off shows up as a large absolute number even if the underlying pattern is ordinary.

How to choose a tool that will still be around next year

A few checks take less time than reading a features page and catch most of the tools that won't last:

• Look for a changelog, blog, or release notes with an entry in the last few months. Silence for a year is a bad sign.
• Check whether the company has a real team page, a support channel that gets answered, or a presence beyond the product's own landing page.
• Be wary of tools whose entire pitch is "ChatGPT, but for X" with no other differentiation - these are the cheapest category to build and the first to go quiet when the operator moves on.
• For a Chrome extension specifically, check the store listing's last-updated date and review recency directly, since a dead website wouldn't necessarily pull the extension down.
• If the tool is central to a workflow, favor one with a paid plan and actual customers over a free tool with no visible business model - a product with revenue has a reason to keep the lights on.

FAQ

How does Toolio check whether a listed tool is still alive?

Listings go through an automated pass first (checking whether the site or store listing responds at all), and anything that fails gets a manual second look to classify what actually happened - dead, parked, hijacked, moved, or simply blocking the automated checker.

What is the difference between "parked" and "dead"?

Parked means the domain resolves to a page offering it for sale or showing placeholder ads - someone let the registration lapse or chose not to renew the product. Dead means there is no response at all: the server is gone or the domain no longer resolves.

Does a broken link always mean the tool shut down?

No. In this recheck, about a third of tools that failed the first automated check turned out to be running fine - some sites now block automated traffic, which looks identical to "down" from a script's point of view but is not the same thing to a real visitor.

Are Chrome extensions more or less likely to survive than websites?

In this dataset, the extensions that got a manual recheck skewed toward alive (877 alive versus 466 removed), while the standalone websites in the same recheck group skewed toward confirmed dead. That is a pattern in this specific sample, not a general rule about extensions versus websites.
