Memories, Custom Instructions, and Skills

Memories, Custom Instructions, and Skills each help Replit work with better context. Choose the one that matches whether the information is a lasting rule, a repeatable procedure, or useful context from past work.

	Who maintains it	When Replit uses it	Best for
Custom Instructions	You or your team	Always, across sessions	Stable preferences and rules you want applied consistently
Skills	You or your team	When relevant to a particular task	Repeatable procedures, workflows, and supporting material
Memories	Replit, with your oversight	When relevant context is useful	Avoiding repetition of useful preferences from past work

Choose the right tool

Use Custom Instructions for a rule that should stay true across your Workspace, such as an approved library or a data-handling requirement. You write them, and Replit does not modify them.
Use a Skill for a reusable approach to a specific kind of work, such as preparing a release or reviewing a design. Stable procedural knowledge belongs in Skills.
Use Memories when Replit can retain useful context from prior work, so you do not need to repeat relevant preferences. Replit can write Memories while you work; they are contextual evidence, not executable instructions.

Your explicit request and Custom Instructions take precedence over Memories. Manage Memories in Settings → Customization → Memory. They do not retain personal or sensitive information, and they are private by default. Sharing with collaborators is optional and off by default.
