Enterprise AI grounded in your company's own knowledge
Ask a question in plain language and get a cited answer assembled from documents, tickets, wikis, and messages across every connected system, with permissions respected.
Reusable agents handle multi-step workflows such as onboarding, account research, or incident follow-up by orchestrating actions across business apps.
Glean automatically picks and routes requests to the right model and reasoning level, giving teams access to 40+ LLMs through a single governed gateway.
Draft on-brand documents, summarise meetings, analyse data, and create content grounded in company context rather than generic model knowledge.

Verify and clean email lists before you hit send

Detects the address types that quietly wreck campaigns, including spam traps, role accounts, catch-all domains and disposable inboxes.
Upload a list in the client area and download a cleaned file in Excel XLSX, CSV or TXT while keeping your original row order.
Verify addresses in real time on signup or import with documented examples for Go, Java, PHP, Python and .NET.
