Product / UX / UI & API

Glean Assistant

Enterprise AI coworker that grounds answers, drafts, slides, voice notes, and task execution in company context across apps and permissions. Glean positions it as the front-door work AI layer for employees, with product screenshots and messaging focused on proactive answers, content generation, and action-taking; the company also has a public $7.2B valuation headline and Gartner/G2 recognition, which signals meaningful enterprise adoption.

Enterprise AI assistant / 'AI coworker' grounded in the Glean Enterprise Graph (RAG over 100+ enterprise connectors), with a Model Hub (multiple frontier LLMs), multimodal output (images/slides/pages), and agentic sub-features (Skills, sub-agent orchestration). Proprietary single-tenant SaaS. May-2026 'enterprise AI coworker' launch verified live June 2026. BORDERLINE: agentic/Skills features touch orchestration_agents, but the product is primarily a human-in-driver enterprise chat/assistant UI grounded in company data, so kept in ui_api per the litmus (AI presented as a tool to the human).
