Devin starts “dreaming” every day: automatically organizing long-term memories, with the approach now open-sourced

Beating AI news flash,AI the programming company Cognition has launched Memory and Dreaming。Memory to let Devin remember users’ preferences, corrections, and project experience across sessions;Dreaming reorganizes these memories in the background every day. Users can directly view what Devin remembers, as well as see what Dreaming has recently modified.

These memories are stored in a personal Memory Drive, essentially a persistent Git repository, with content organized mainly in Markdown files. One of them is a brief MEMORY.md file that serves as the entry point and index, and is loaded into the context at the start of each new session. Devin then searches for relevant memory files based on the current task, much like searching a code repository, without needing to stuff the entire memory repository into the prompt.

Multiple Devin sessions can read and write to the same set of memories. Each session has its own Git checkout; after modifying memories, it commits and merges them back into Memory Drive. When concurrent modifications occur,Git exposes the conflicts, preventing different sessions from overwriting one another.Dreaming itself is a background session that runs automatically every day. It rechecks past conversations and existing memories, merges duplicate content, deletes temporary or long-unused information, and fills in experience that had not previously been recorded.

Cognition also separated this approach into an Agent Memory Repo and open-sourced it. Other Agents such as Claude Code and Cursor can use a similar approach to store long-term memories in files and manage them through Git. However, the open-source version provides the memory structure and workflow; automatically running Dreaming every day, as Devin does, still requires additional configuration.

Key points

Beating AI reports that Cognition has launched Memory and Dreaming。
reports that Memory is used to save users’ preferences, corrections, and project experience across sessions, while Dreaming reorganizes the memories in the background every day.
Users can view the memories saved by Devin, as well as Dreaming its recent modifications.
The memories are stored in a personal Memory Drive; this storage is a persistent Git repository, with content organized mainly using Markdown files.
MEMORY.md is used as the entry point and index, and is placed into the context at the start of each new session.
Devin searches for relevant memory files based on the current task, without needing to place the entire memory repository into the prompt.
Multiple Devin sessions can read and write to the same memories; each session uses its own Git checkout and commits the modifications, merging them back into Memory Drive。
reports that Git exposes conflicts during concurrent modifications, preventing different sessions from overwriting one another.
Dreaming checks past conversations and existing memories, merges duplicate content, deletes temporary or long-unused information, and adds experience that had not previously been recorded.
reports that Cognition separated the approach into an Agent Memory Repo and open-sourced it; other Agents such as Claude Code and Cursor can also use a similar approach to manage long-term memories.
The open-source version provides the memory structure and workflow; automatically running Dreaming still requires additional configuration.

AI-assisted interpretation

The following is analysis, separate from reported facts. Verify important claims independently.

This design is like preparing a AI programming assistant with a notebook repository that can be saved over the long term. Devin first reads a brief index, then looks for relevant files according to the task; in the background,Dreaming periodically organizes these notes.Git records the modifications and displays conflicts when multiple sessions edit simultaneously.

Why it matters to readers

If the reported features work as described, they could allow Devin to retain information accumulated in ongoing projects, reducing the need for users to repeatedly explain their preferences, corrections, and project experience. Making the related structure and workflow open source could also lead other Agents to adopt similar file-based memory systems.

Beginners can understand Memory as long-term notes, and Dreaming as a background task that automatically organizes the notes every day. The open-source version does not mean automatic organization works out of the box; the article explicitly says that additional configuration is still required.

Risks and unknowns

The provided material does not include an official Cognition announcement, so the scope of the feature rollout cannot be independently confirmed.
The provided material does not provide the Agent Memory Repo URL, so its license, code content, and maintenance status cannot be verified.
The material does not explain the specific effects on memory accuracy, privacy protection, data deletion rules, or user control.
