Skillsync, a Y Combinator W26 startup, lets users move AI chat sessions seamlessly across different coding agents.
Skillsync, a Y Combinator Winter 2026 cohort startup, has unveiled a desktop tool that lets developers carry AI‑driven chat sessions from one coding assistant to another. The “local‑first” app captures the full context of a session—including the conversation, reasoning steps and tool usage—and stores it in a searchable repository that any supported agent can retrieve.
The move addresses a growing pain point for engineers who juggle multiple AI agents such as Claude Code, Codex and Cursor. Today, each platform keeps its own conversation logs in proprietary formats, forcing users to recreate context when they switch tools or collaborate with teammates. Skillsync promises to free that context from any single agent, allowing a session to be moved intact across agents or shared with colleagues as a reusable “skill.”
The relevance of portable AI sessions extends beyond convenience. By preserving reasoning trails and tool histories, the platform could reduce duplicated effort, accelerate onboarding, and improve the reproducibility of AI‑assisted code work. Its searchable archive also opens the door to building libraries of high‑quality prompts that can be reused across projects.
What to watch next is whether major coding assistants adopt Skillsync’s interoperability layer and how quickly development teams integrate the tool into their workflows. The founders—former Rust engineers from payments firm Juspay—have positioned the product as a “GitHub for your agent sessions,” a claim that will be tested as the ecosystem of AI coding assistants continues to expand. Early uptake and potential follow‑on funding will be key indicators of the startup’s impact on the emerging market for AI‑enhanced development tools.
