Problem

Descript lets people edit video like a text document. Many users still needed to direct each edit by hand, and the company wanted an assistant that could handle complex edits with a sense of taste.

Approach

Descript first added Claude in mid-2024 for fixed workflows such as Edit for clarity and Create clips. It then built Underlord, an agent that runs on Claude and handles multi-step edits. In January 2026 Claude Sonnet 4.5 became the default for self-serve users and Claude Opus 4.6 the default for enterprise customers. The company said it can integrate a new Claude model in as little as half a day.

Results

about 9%higher export rate for agent users than for non-agent usersVendor case study[1]

Takeaway

Descript tied the agent to commercial results, with higher export and conversion rates among users who tried it. The company did not say how it controlled for users who were already more engaged.
