# AI coding assistants & agents tools used by Artificial Intelligence companies usedby lists 16 Artificial Intelligence companies using 9 AI coding assistants & agents tools. The most used is Cursor: 4 of the 16 Artificial Intelligence companies on usedby, every proof level counted. These are counts of the companies usedby tracks, not a market share. Data as of 2026-10-25. ## Ranking Tools ranked by the companies of the 16 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. | # | Tool | Companies | Confirmed | Declared | Observed | Job posts only | Last check | |---|---|---|---|---|---|---|---| | 1 | [Cursor](https://www.usedby.ai/tools/cursor.md) | 4 | 0 | 0 | 3 | 1 | 2026-10-24 | | 2 | [Augment Code](https://www.usedby.ai/tools/augment-code.md) | 3 | 3 | 0 | 0 | 0 | 2026-10-20 | | 3 | [Cognition](https://www.usedby.ai/tools/cognition.md) | 3 | 0 | 0 | 3 | 0 | 2026-10-25 | | 4 | [Warp](https://www.usedby.ai/tools/warp.md) | 3 | 0 | 0 | 3 | 0 | 2026-10-17 | | 5 | [Factory](https://www.usedby.ai/tools/factory.md) | 1 | 1 | 0 | 0 | 0 | 2026-10-17 | | 6 | [Bito](https://www.usedby.ai/tools/bito.md) | 1 | 0 | 0 | 1 | 0 | 2026-10-04 | | 7 | [Sourcegraph](https://www.usedby.ai/tools/sourcegraph.md) | 1 | 0 | 0 | 1 | 0 | 2026-10-19 | | 8 | [Tessl](https://www.usedby.ai/tools/tessl.md) | 1 | 0 | 0 | 1 | 0 | 2026-10-22 | | 9 | [GitHub Copilot](https://www.usedby.ai/tools/github-copilot.md) | 1 | 0 | 0 | 0 | 1 | 2026-10-25 | ## 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. | Tool | Company | Proof | Source | Last check | |---|---|---|---|---| | Cursor | [OpenAI](https://www.usedby.ai/companies/openai.md) | Observed | [cursor.com](https://cursor.com/customers), captured 2026-10-24 | 2026-10-24 | | Cursor | [Grammarly](https://www.usedby.ai/companies/grammarly.md) | Observed | [cursor.com](https://cursor.com/customers), captured 2026-10-24 | 2026-10-24 | | Cursor | [Decagon](https://www.usedby.ai/companies/decagon.md) | Observed | [cursor.com](https://cursor.com/customers), captured 2026-10-24 | 2026-10-24 | | Cursor | [Lovable](https://www.usedby.ai/companies/lovable.md) | Signal (job post) | [jobs.ashbyhq.com](https://jobs.ashbyhq.com/lovable/ac86ab57-ff2e-4a49-83f8-51dd6bbc2cbf), captured 2026-10-21 | 2026-10-21 | | Augment Code | [Handoff](https://www.usedby.ai/companies/handoff.md) | Confirmed | [augmentcode.com](https://www.augmentcode.com/customers/handoff), captured 2026-10-09 | 2026-10-20 | | Augment Code | [LMNT](https://www.usedby.ai/companies/lmnt.md) | Confirmed | [augmentcode.com](https://www.augmentcode.com/customers/lmnt), captured 2026-10-09 | 2026-10-20 | | Augment Code | [Napster](https://www.usedby.ai/companies/napster.md) | Confirmed | [augmentcode.com](https://www.augmentcode.com/customers/napster), captured 2026-10-09 | 2026-10-20 | | Cognition | [Exa](https://www.usedby.ai/companies/exa.md) | Observed | [cognition.com](https://cognition.com/), captured 2026-10-25 | 2026-10-25 | | Cognition | [Gamma](https://www.usedby.ai/companies/gamma.md) | Observed | [cognition.com](https://cognition.com/), captured 2026-10-25 | 2026-10-25 | | Cognition | [OpenRouter](https://www.usedby.ai/companies/openrouter.md) | Observed | [cognition.com](https://cognition.com/), captured 2026-10-25 | 2026-10-25 | | Warp | [Google](https://www.usedby.ai/companies/google.md) | Observed | [warp.dev](https://www.warp.dev/customers), captured 2026-10-17 | 2026-10-17 | | Warp | [OpenAI](https://www.usedby.ai/companies/openai.md) | Observed | [warp.dev](https://www.warp.dev/customers), captured 2026-10-17 | 2026-10-17 | | Warp | [Anthropic](https://www.usedby.ai/companies/anthropic.md) | Observed | [warp.dev](https://www.warp.dev/customers), captured 2026-10-17 | 2026-10-17 | | Factory | [Groq](https://www.usedby.ai/companies/groq.md) | Confirmed | [factory.com](https://factory.com/case-studies/groq), captured 2026-10-17 | 2026-10-17 | | Bito | [Anthropic](https://www.usedby.ai/companies/anthropic.md) | Observed | [bito.ai](https://bito.ai/case-studies/), captured 2026-10-04 | 2026-10-04 | | Sourcegraph | [Midjourney](https://www.usedby.ai/companies/midjourney.md) | Observed | [sourcegraph.com](https://sourcegraph.com/), captured 2026-10-19 | 2026-10-19 | | Tessl | [DeepL](https://www.usedby.ai/companies/deepl.md) | Observed | [tessl.io](https://tessl.io/pricing), captured 2026-10-22 | 2026-10-22 | | GitHub Copilot | [UIPath](https://www.usedby.ai/companies/uipath.md) | Signal (job post) | [jobs.ashbyhq.com](https://jobs.ashbyhq.com/uipath/f312ccc8-c71e-4d86-a1d5-767dba970edd), captured 2026-10-25 | 2026-10-25 | ## Method Public customer lines of active AI coding assistants & agents tools at companies classified in Artificial Intelligence.
