MaiBot vs mex

MaiBot: MaiBot (MaiSaka) is an LLM-based chat agent built to feel human in group chats rather than act as a task assistant. It chats casually, picks when to speak, imitates group slang and builds up an understanding of each person, with a plugin and event system for extensions.; 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.

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.
