Launch HN: Skillsync (YC W26) – AI chat sessions made portable across agents (skillsync.com)

Skillsync, a new startup from Y Combinator’s Winter 2026 cohort, has launched a revolutionary platform that enables AI chat sessions to be easily transferred across various agents and teammates. By emphasizing a "local first" approach, Skillsync eliminates the need for lock-ins and the hassle of repeatedly explaining context, thus improving collaboration among users of different AI models like Claude, CodeCodex, and Hermes. The platform offers seamless integration, allowing users to effortlessly continue conversations regardless of the agent being utilized, enhancing productivity and user experience. This development is significant for the AI/ML community as it addresses a common pain point of interoperability among various AI systems. By facilitating a more cohesive workflow, Skillsync has the potential to drive greater adoption of AI technologies in team settings, where diverse tools are often in use. The ability to maintain continuity in conversations and ideas across different AI platforms could streamline development processes and foster innovation, making it easier for teams to leverage the unique strengths of each model while minimizing friction in communication.
