Summary
Picture a marketing manager reading a developer forum thread titled something like 'search is getting worse'. Five years ago the replies would have been a list of other search engines to try. Now many of them name a chat assistant instead.
We tracked every Hacker News comment that discussed search engines or search results from 2015 to September 2026, and counted which alternatives people named. This is a who-is-mentioned count, not a quality ranking.
In 2026, AI assistants were named in 16.7% of these comments and traditional search alternatives in 9.4%. The crossover happened in 2023, the first full year after ChatGPT launched.
What we measured
We used the public Hacker News table on Google BigQuery and kept live comments from January 2015 to September 2026 that mention search engines, web search, search results, search quality, SERPs, Google Search or googling. That gave 130,942 comments.
In each comment we looked for names of other search engines (such as DuckDuckGo, Bing, Kagi, Brave Search, Startpage, Ecosia, Yandex, SearX, Marginalia, Mojeek, Neeva and Qwant) and AI assistants or answer engines (such as ChatGPT and GPT models, Claude, Gemini, Perplexity, Copilot, Phind, You.com, DeepSeek and Grok). A comment can name several. Shares are mentions divided by all search comments that year.
AI assistants overtook traditional alternatives in 2023
From 2015 to 2022, when people discussed search on Hacker News, roughly 8% to 14% of comments named a different search engine. AI tools barely registered.

The lines crossed in 2023. Since then AI assistants have been named in 11.7% to 16.7% of search comments each year, while traditional alternatives slipped from 14.3% to 9.4%. Mentions of GPT models in 2020 and Copilot in 2021 mostly refer to developer tools, not search.
Who gets named in search discussions
The individual names show how attention spread from one assistant to several.

|---|---|---|---|---|---|---|
| ChatGPT / GPT models | 0.5 | 2.5 | 13.7 | 8.7 | 10.4 | 7.9 |

ChatGPT has been the most-named product in search discussions every year since 2023. In 2026 Claude (6.6%) and Gemini (5.0%) were close behind. Among traditional alternatives, Kagi has led since 2024. Gemini figures before 2023 mostly refer to an older internet protocol of the same name, and Bing in 2023 includes Bing Chat.
AI comes up in almost half of all search talk
Counting any AI word, such as AI, LLM or AI Overview, shows how much the topic has merged with search itself.
% of search comments
| Year | Any AI term % | Comments with AI term | Search comments |
|---|---|---|---|
| 2,019 | 1.8 | 180 | 10,211 |
| 2,020 | 2.1 | 249 | 11,674 |
| 2,021 | 3 | 374 | 12,637 |
| 2,022 | 6.6 | 1,026 | 15,538 |
| 2,023 | 25.7 | 4,445 | 17,287 |
| 2,024 | 28.2 | 3,536 | 12,552 |
| 2,025 | 42.2 | 5,612 | 13,284 |
| 2,026 | 45.8 | 4,398 | 9,609 |

In 2020 only 2.1% of search comments mentioned AI. By 2026 it was 45.8%. Many of these comments are about AI features inside search results rather than separate assistants, which helps explain why this figure is much higher than the named-assistant share.
What this means
When technical buyers talk about where they look for answers, AI assistants now come up more often than other search engines. Your customers may ask several of them, and each one draws on different sources. Being findable in classic search results is still the base, but it is no longer the whole picture. Useful AI SEO services build on that base instead of replacing it.
Start by checking what ChatGPT, Claude, Gemini and Perplexity say when asked about your service and your town. A free AI visibility audit does that for you across all four, and a good GEO agency should be able to show you the same results before quoting any work.
Limits
This is a count of mentions in comments, not market share or usage. A name can be mentioned to praise it, criticize it or just compare it.
Name matching can pick up unrelated uses, such as Gemini the protocol, Claude as a person's name or GitHub Copilot. We note where this affects earlier years.
Search comments are found by keywords, so some search discussions were missed and some matched comments are only partly about search.
Dead and deleted comments carry no text in the dataset. 2026 covers January to September.
Hacker News is a developer and founder audience.
