## Ranking

Tools ranked by the companies of the 44 Artificial Intelligence companies on usedby that use them. Each company counts once per tool, at its strongest proof. Ties go to more confirmed, then declared, then observed companies.

## Customers per tool

Every line is a customer, at one of three proof levels: confirmed (a case study, a named quote, a press release, or the company's own public account of using the tool (its own site, or a post by one of its executives, VP or above)), observed (the vendor shows the company on its own pages) or signal (a job post shows the company's employees use the tool, the weakest proof). A line the company declared to usedby itself is marked declared. A signal is never a case study or a vendor listing. Strongest proof first. "Last check" is the later of the line's re-verification and its latest capture.

## Method

Public customer lines of active Vector databases & search engines tools at companies classified in Artificial Intelligence. 19 companies that sell software were left out, so a vendor is never counted as a user. Company mix by strongest proof: 9 confirmed, 0 declared, 35 observed and 0 signals.

## Questions

### Which Vector databases & search engines tools do Artificial Intelligence companies use most?

Qdrant leads: 18 of the 44 Artificial Intelligence companies on usedby that use Vector databases & search engines tools use it. Next: Pinecone (9), Weaviate (5), Zilliz (5), and LanceDB (5).

### How many Artificial Intelligence companies use Vector databases & search engines tools?

44 Artificial Intelligence companies on usedby use at least one of 7 Vector databases & search engines tools. It counts the companies usedby tracks.

### What proof backs these lines?

Of the 44 companies, each counted at its strongest proof: 9 confirmed, 0 declared, 35 observed and 0 known from a job post.

### How does usedby build this ranking?

usedby counts each Artificial Intelligence company once per tool, from public proof: case studies, press releases, the company's own site or its declaration to usedby, vendor customer pages and job posts. 19 software vendors are left out. Every line shows its proof and the date usedby last checked it.
