simplememory

A lightweight persistent memory plugin for LM Studio. Gives your local LLM the ability to remember facts, preferences, and context across sessions using a plain markdown file stored on your machine.

This is the original simplememory plugin. If you found this via a fork of a fork, this is where it started.

Setup

• The memory file and folder will be created automatically on first use.
• Set all tools to Always Allow so memory reads and writes happen without confirmation prompts.

Tools

• read_memory - reads the memory file at session start. Optionally pass a section name to read just that section.
• save_memory - appends a new standalone fact.
• update_memory - finds and replaces an existing passage (corrections, deletions).
• delete_memory - removes a specific passage entirely.
• search_memory - returns only entries containing a query string.
• save_to_section - appends content inside a named structured section.
• replace_section - replaces a whole section's body.
• get_current_time - returns the current local date and time.

Destructive operations (update_memory, delete_memory, replace_section) automatically keep a timestamped backup of the memory file beforehand, in a backups/ folder next to it, retaining the most recent 20.

System prompt

For reliable automatic memory behavior, instruct your model to call read_memory at the start of every session and save_memory (or the appropriate structured tool) whenever new information worth retaining is shared. The exact wording will depend on your model and preferences.

Notes

• The memory file is plain markdown - you can read and edit it directly at any time
• Tested with Qwen 3.5 and Qwen 3.6 in LM Studio 0.4.9-0.4.19
• Model behavior depends on how well the model follows tool-use instructions - larger models are more reliable
