NaN Forget

Long-term memory for AI coding tools.

Your AI forgets everything when the session ends. NaN Forget fixes that.

Install (3 steps)

npx nan-forget setup

That's it. The wizard installs Ollama, embeddings, Claude hooks, MCP config, and a project AGENTS.md for Codex-style agents. Restart Claude Code or reopen Codex. Your AI now remembers.

No API keys needed. No Docker needed. Runs locally. Free forever.

How It Works

flowchart LR
    A["You talk to your AI tool"] --> B["It learns things"]
    B --> C["nan-forget saves to SQLite"]
    C --> D["Session ends"]
    D --> E["New session starts"]
    E --> F["nan-forget loads context"]
    F --> G["Your AI remembers"]

You work normally. Your agent saves decisions, preferences, and facts to a local SQLite memory database as you go.
Session ends. Memories persist in ~/.nan-forget/memories.db. Aging memories get automatically compacted into long-term entries.
New session starts. nan-forget loads context from past sessions. Auth decisions from 3 months ago on Project A surface when you work on Project B today.

Automatic Memory Handling

You never call save or search manually. Here's what happens behind the scenes:

Claude Code (fully automatic)

Event	What fires	What happens
Session starts	`memory_sync`	Lightweight handshake — checks health, loads stats, lists projects. No heavy search.
You send a message	UserPromptSubmit hook	`nan-forget recall` auto-searches memory for relevant context and injects it into the conversation.
You discuss a topic	`memory_search`	Claude searches the DB dynamically whenever relevant context might exist — like how you recall things on-demand.
Claude learns something	`memory_save`	Claude saves decisions, preferences, and facts immediately. Tool descriptions tell Claude "you MUST call this."
Claude writes a `.md` file	PostToolUse hook	`memory-sync.js` intercepts the write, parses frontmatter, and auto-saves it to SQLite via `nan-forget add`.
Session ends	SessionEnd hook	`session-end.js` scans the conversation transcript for unsaved decisions/facts and saves the top 5 to the DB.
Every 10 saves or 24h	Auto-consolidate	Aging memories get clustered and compacted into long-term entries. Originals are archived.

Four layers of protection ensure nothing is lost:

Auto-recall on every message (UserPromptSubmit hook)
Claude saves proactively (directive tool descriptions)
Hook catches .md writes (PostToolUse intercept)
End-of-session sweep (SessionEnd transcript scan)

Codex, Cursor, and other tools

Codex and similar agents work well with nan-forget, but they usually need instruction files or shell/API fallbacks instead of Claude's hook model:

Run setup: npx nan-forget setup
Use the generated AGENTS.md in your repo. It tells Codex-style agents to sync, search, save, and checkpoint automatically.
Use REST or CLI fallback during conversation. Agents can call the REST API on localhost:3456 or local commands like nan-forget sync, nan-forget search, nan-forget add, and nan-forget checkpoint.

The REST API and CLI now mirror the important memory workflows closely enough that memories saved by Claude are searchable from Codex and vice versa.

# Start the REST API
nan-forget api

# The system prompt tells your agent exactly what endpoints to call
nan-forget prompt

Slash Commands

Type these in Claude Code:

Command	What it does
`/nan-forget`	Load context from past sessions
`/nan-forget stats`	Show memory health
`/nan-forget clean`	Run garbage collection
`/nan-forget compact`	Force memory consolidation
`/nan-forget health`	Check if services are running
`/nan-forget start`	Start all services
