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 | |---|---|---|---|---| | Harvey | [Repsol](https://www.usedby.ai/companies/repsol.md) | Confirmed | [harvey.ai](https://www.harvey.ai/customers/repsol), captured 2026-10-01 | 2026-10-24 | | Harvey | [National Grid](https://www.usedby.ai/companies/national-grid.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [Gunvor Group](https://www.usedby.ai/companies/gunvor-group.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [MET Group](https://www.usedby.ai/companies/met-group.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [Tecnicas Reunidas](https://www.usedby.ai/companies/tecnicas-reunidas.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [VTTI](https://www.usedby.ai/companies/vtti.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [Enagas](https://www.usedby.ai/companies/enagas.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Sirion | [Galp](https://www.usedby.ai/companies/galp.md) | Confirmed | [sirion.ai](https://www.sirion.ai/library/customer-stories/galp-energia/), captured 2026-10-07 | 2026-10-19 | | Sirion | [Chevron](https://www.usedby.ai/companies/chevron.md) | Observed | [sirion.ai](https://www.sirion.ai/), captured 2026-10-07 | 2026-10-07 | | Sirion | [Amprion](https://www.usedby.ai/companies/amprion.md) | Observed | [sirion.ai](https://www.sirion.ai/), captured 2026-10-19 | 2026-10-19 | | Sirion | [Aramco](https://www.usedby.ai/companies/aramco.md) | Observed | [sirion.ai](https://www.sirion.ai/), captured 2026-10-19 | 2026-10-19 | | Sirion | [Siemens Energy](https://www.usedby.ai/companies/siemens-energy.md) | Observed | [sirion.ai](https://www.sirion.ai/), captured 2026-10-19 | 2026-10-19 | | SpotDraft | [BeZero Carbon](https://www.usedby.ai/companies/bezero-carbon.md) | Confirmed | [spotdraft.com](https://www.spotdraft.com/customer-stories/abnormal-security), captured 2026-10-18 | 2026-10-18 | | SpotDraft | [Chaberton Energy](https://www.usedby.ai/companies/chaberton-energy.md) | Confirmed | [spotdraft.com](https://www.spotdraft.com/customer-stories/chaberton-energy), captured 2026-10-07 | 2026-10-18 | | SpotDraft | [Doral Renewables](https://www.usedby.ai/companies/doral-renewables.md) | Confirmed | [spotdraft.com](https://www.spotdraft.com/customer-stories/doral-renewables), captured 2026-10-07 | 2026-10-18 | | SpotDraft | [SUN Mobility](https://www.usedby.ai/companies/sun-mobility.md) | Observed | [spotdraft.com](https://www.spotdraft.com/customer-stories), captured 2026-10-18 | 2026-10-18 | | Legora | [Audax Renewables](https://www.usedby.ai/companies/audax-renewables.md) | Observed | [legora.com](https://legora.com/customers), captured 2026-10-24 | 2026-10-24 | | Legora | [Exus Renewables](https://www.usedby.ai/companies/exus-renewables.md) | Observed | [legora.com](https://legora.com/customers), captured 2026-10-24 | 2026-10-24 | | Legora | [Galp](https://www.usedby.ai/companies/galp.md) | Observed | [legora.com](https://legora.com/customers), captured 2026-10-24 | 2026-10-24 | | Legora | [Gransolar Group](https://www.usedby.ai/companies/gransolar-group.md) | Observed | [legora.com](https://legora.com/customers), captured 2026-10-24 | 2026-10-24 | | Luminance | [TotalEnergies](https://www.usedby.ai/companies/totalenergies.md) | Confirmed | [luminance.com](https://www.luminance.com/customers/transforming-legal-operations-across-the-enterprise), captured 2026-10-07 | 2026-10-17 | | Luminance | [Fluence](https://www.usedby.ai/companies/fluence.md) | Observed | [luminance.com](https://www.luminance.com/customers), captured 2026-10-17 | 2026-10-17 | | LegalOn | [Electrical Consultants, Inc.](https://www.usedby.ai/companies/electrical-consultants-inc.md) | Confirmed | [legalontech.com](https://www.legalontech.com/customers/eci), captured 2026-10-08 | 2026-10-18 | | Ironclad | [Shell](https://www.usedby.ai/companies/shell.md) | Observed | [ironcladapp.com](https://ironcladapp.com/pricing), captured 2026-10-24 | 2026-10-24 | ## Method Public customer lines of active Legal AI tools at companies classified in Energy, Utilities & Cleantech.
