An AI email assistant that writes replies and full messages inside Gmail, Outlook and Zendesk
Turn a short phrase or bulleted list into a complete, professional email, including cold outreach, applications and follow-ups.
Ghostwrite reads the incoming message and drafts a contextually appropriate full reply in a single click.
Switch between formal, friendly, concise and persuasive registers so the same content fits different recipients and situations.
Text is corrected for spelling, grammar and clarity as it is generated, so nothing goes out with obvious mistakes.

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.
