Google plans to begin automatically migrating Gemini Gems to Skills on November 17, 2026. Existing Gems will remain usable until they migrate, so users do not need to move them themselves.
Google will begin migrating Gems to Skills on November 17, 2026
Google’s announced migration is scheduled to start on November 17, 2026. The date marks the start of the transfer, while each Gem remains usable until its own migration.
What Gemini Gems do in practice
Gems let you save custom instructions for recurring or specialized tasks, with files available to provide context. Examples include refining prompts, preparing customer-support replies, reviewing transcripts, planning wellness routines, and organizing travel. A demonstrated workflow also uses Google Drive documents and NotebookLM notebooks as context.
What reference files Skills support
Google describes Skills as reusable instruction sets for Gemini Apps. Google’s Skills help documentation says they support plain-text reference files up to 100 MB. PDFs and images are not supported as reference files.
