What Happened

David Singleton introduces Dreamer, a platform designed to democratize AI agent creation and usage for consumers without technical backgrounds. Dreamer includes a personal agent called Sidekick, which users can personalize to assist with daily tasks. The platform is currently in beta, with a waitlist available at dreamer.com.

Singleton, along with co-founders Hugo Barrett and Nicholas Chekkov, previously worked on Google's mobile apps and Android, which informed their approach to building Dreamer. The platform is likened to an app store for AI agents, allowing users to create, modify, and share agentic apps easily. Users can modify agents using natural language, facilitated by the Sidekick.

Dreamer hosts a gallery of hundreds of agents and tools, focusing on personal productivity and information management. Tool builders can earn money based on the usage of their tools by agents, with a $10,000 prize offered for the best tool added by mid-April. Dreamer supports agentic commerce with various protocols, akin to the early web era.

The Dreamer platform eliminates the need for users to manage databases or API keys by hosting all built agents and apps. It offers a Builders in Residence program, inspired by the Lego Master Builder program, to encourage creativity on the platform. Dreamer also provides an SDK and CLI for building agents, using TypeScript for strong typing and compile-time error checking.

Dreamer's Sidekick acts as a traffic cop, managing interactions between agents and ensuring user privacy and security. It builds a memory of the user over time, improving with more usage, and allows deep technical exploration while explaining processes in simple terms. Dreamer emphasizes a pro-builder approach, allowing some users to skip the waitlist via a special link.

Singleton highlights the differences between his past role as CTO at Stripe and his current role as CEO of Dreamer, focusing on go-to-market strategies and user engagement. Dreamer uses coding and marketing agents to accelerate operations, with a hiring focus on engineers who can effectively work with coding agents. The platform also provides a curated set of tools for various functions, including image understanding, generation, and text-to-speech.
