AI Tools That Died in September 2026

Original data by RightAIChoice · computed from the live catalog, as of October 23, 2026 · October 1, 2026 edition · refreshed monthly · data CC BY 4.0

TL;DR — as of October 23, 2026

122 AI tools went dark in September 2026 — 102 websites stopped responding and 20 domains were parked for sale — out of 8,222 tools under continuous verification.

  • A tool counts as dead here only when its own website failed a probe in September 2026 and has stayed failed on every probe since — a parked domain, a domain that no longer resolves, or a homepage that answers with an error. Redirects and single failed probes are never counted.
  • The tools that died had been under verification for a median of 63 days before the first failure, so most were established listings, not tools that were never real.
  • The month-by-month table shows how many first failures turn out to be permanent; the difference is why a single failed check is never reported as a death.

How many AI tools went dark each month?

"First flagged" counts tools whose website first failed that month; "still down" counts those that never came back — only those are deaths. The gap is transient failures (DNS blips, outages, bot walls) that cleared on a later probe.

How is this report computed?

Population: every published tool in the RightAIChoice catalog, each of which has its website probed on a rolling schedule (check-link-health) with a browser-like user agent, retries with backoff, and a separate DNS check.

Record: every change to a tool's website status is written to tool_state_history with a timestamp. The report takes, per tool, the FIRST time the status became dead, parked, or hijacked, and keeps the tool only if its status is still one of those today.

Focus month: the last complete calendar month before the newest status observation (October 23, 2026). "Days tracked" is the time between the tool entering the catalog and the first failure.

Categories are the tool's primary category. Rows with fewer than five deaths are combined, following the site-wide rule against publishing very small counts.

Sources. tools · tool_state_history (field = website_flag) · categories / tool_categories · SQL function research_graveyard_monthly()

How this report is made: every number is computed directly from the RightAIChoice catalog by a fixed database query (named under Sources) — no number on this page is estimated or generated by a language model. The explanatory text is drafted with a mixture of AI models and reviewed by a human editor before publication. Report rows describe what we observed on the dates shown; they are not verdicts about any vendor.

FAQ

How do you decide an AI tool is dead?

Three signals, all about the tool's own website: it no longer responds (DNS failure, connection refused, or an error status on the homepage), its domain resolves to a parking page offering the domain for sale, or the domain now serves unrelated content. A tool is listed only if the first failure happened in the report month AND every later probe agreed. A redirect to another company is recorded separately and never counted as a death.

Why is "first flagged" higher than "still down"?

Because websites flicker. A DNS resolver blip, an outage, or an anti-bot wall can fail one probe and pass the next. We keep the first flag in the record so the gap is visible, and count only tools that never came back.

Does a dead website mean the company has shut down?

Not necessarily — some products live on inside an acquirer or under a new name. This report records what the registered website does today; it does not claim to know the business reason.

Can I use or cite this data?

Yes. The tables on this page and the JSON and CSV files linked from it are published under CC BY 4.0 — free to use, including commercially, with attribution. Cite "RightAIChoice" with a link to this page and the as-of date shown at the top.

How often is this report updated?

A new edition is computed on the first of every month from the live catalog. Each edition carries the date of the newest observation it read, so a quoted figure can always be tied to a date.
