Glean launches Tau desktop AI, beats Claude on cost

Glean Technologies unveiled Glean Tau, a desktop workspace connecting enterprise AI to local files, apps and code. The company claims a 5.2-times token-cost advantage over Anthropic's Claude Cowork and user preference of 3.6 times, with Tau capable of planning and executing multistep tasks autonomously. The launch headlined Glean's GO conference in San Francisco, alongside six other products covering usage analytics, proactive task management, interactive dashboards, team chat, AI governance and security threat detection. Several features are in beta or not yet released. Glean is valued at $7.2 billion following a $150 million Series F in June 2025.
