llm-context.py vs mex
llm-context.py: LLM Context provides smart context management for LLM development, streamlining the process of sharing relevant project files with AI. It leverages intelligent selection and rule-based filtering to ensure optimal context, addressing issues like token limits and manual file fetching.; mex: mex provides persistent, navigable project memory for AI coding agents, allowing every session to start with the right context instead of a cold prompt. It structures agent memory through a markdown scaffold, offers CLI tools for drift detection against the real codebase, and synchronizes context to keep agents aligned and reduce token usage.

TL;DR
llm-context.pyMemory & Context · ★ 307
Human-centric context sharing for LLM chat interfaces via clipboard.
mexMemory & Context · ★ 1.8k
When to choose:
- Your AGENTS.md or CLAUDE.md has grown too big and you want a small anchor plus routed context files.
- You want memory as plain markdown in the repo, reviewable in pull requests and diffable.
- You want drift checks that run without AI tokens and flag missing paths, stale files and broken scripts.
When to skip:
- You want recall across unrelated projects or conversations; mex lives inside one repository.
- You have a small project: another set of files to maintain may cost more than it saves.
- You expect the AST code-graph feature today: the README marks it as an unreleased preview.
