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

Skillsync tackles a growing pain point for developers and businesses using multiple AI chat agents: the inability to carry context and conversation history between different tools. By making AI sessions portable, the startup aims to reduce lock-in and repetitive setup, which could reshape how people integrate AI assistants into daily workflows. As a YC-backed launch, it also signals continued investor interest in infrastructure that smooths the rough edges of the fast-growing AI agent ecosystem.

• Skillsync lets AI chat sessions move across different agents rather than being locked to one platform.
• The product addresses a common frustration of losing context when switching between AI tools.
• It is part of Y Combinator's W26 batch, reflecting ongoing investment in AI infrastructure startups.
