Mem-Forever

永久记忆 · 跨会话 · 跨模型
A persistent memory layer for AI agents, built on the I-Lang protocol.

中文 | 日本語 | 한국어 | Español | Français | Deutsch | Português | Русский

Abstract

Every AI tool forgets you after every session. You close a window, and your preferences, decisions, and lessons vanish. Next session, you start from zero.

Mem-Forever is a Git-native memory layer that lets any AI agent remember you permanently. Memories are stored as compact I-Lang structures in your own private repo, readable by humans, parseable by machines, and portable across every tool.

Where context windows forget, Mem-Forever endures.

Why

Quick Look

.ilang/
  soul.md      ← who you are (auto-generated from conversation)
  memory.md    ← what you decided, learned, built (auto-appended)

::DNA{user}
::CORE{
  ::CONTEXT{role:fullstack_dev|experience:10yr}
  ::GENE{style|conf:confirmed}
    T:conclusions_first
    T:minimal_output|when:simple
    A:verbose_without_signal⇒waste
}
::LESSONS{
  ::LESSON{id:serverless_no_shared_state|conf:confirmed}
}

Every preference is addressable, scoped, versioned, and falsifiable.

Setup (seconds)

Step 1   Click "Use this template" → Create a new repository → Set to Private.

Step 2   There is no step 2.

Open the repo with any AI tool. It reads the instruction files, asks you a few questions, builds your profile. From that point on, it remembers.

Works With Everything

Working on a different project?

One sentence restores full context:

My memory repo is at https://github.com/YOU/mem-forever. PAT: ghp_xxx. Clone it, read .ilang/soul.md and .ilang/memory.md, then come back here.

Multiple projects?

Use this template again. mem-forever-work, mem-forever-research, mem-forever-client-x. Each repo is an independent memory. Same engine, different context.

soul.md is your behavioral profile. Built from conversation, sharpened every session through mutation and decay rules. Think of it as DNA that travels with you.

memory.md is your logbook. Decisions, lessons, facts, progress. Append-only. Git history preserves everything.

You never write these files. Your AI does. You can read, edit, or delete them anytime. They are yours.

Comparison

Under the Hood

The instruction files contain behavioral rules written in I-Lang v3.0, a structured protocol that AI models parse natively. These rules tell the AI how to extract preferences, format memories, handle conflicts, and evolve your profile over time.

You don't need to know I-Lang. You just talk to your AI, and it gets better at working with you.
