  Measured memory for coding agents.

Automatic background memory for Claude Code. Fire and forget — no API keys needed.

Memor watches your coding sessions, extracts decisions and patterns, and recalls relevant context on every prompt. Zero configuration. One install. Your agent remembers everything.

---

Quick Start

# Install globally (recommended)
pipx install memor-cli

# Install the Claude Code hook + download embedding model (~60MB)
memor install-hook

# Start the background daemon
memor daemon

That's it. Every Claude Code prompt now gets automatic context recall. Open the dashboard to see it working:

memor dashboard
# Opens http://localhost:8420

Alternative install: pip install memor-cli works too — just make sure ~/.local/bin is on your PATH so the memor command is available.

How It Works

  You type a prompt in Claude Code
      |
      v
  Hook fires (UserPromptSubmit)
      |
      v
  Embed query locally (model2vec, ~2ms)
      |
      v
  Hybrid scoring: similarity + recency + kind weight + quality
      |
      v
  Inject relevant context into prompt
      |
      v
  Claude sees your past decisions, bugfixes,
  architecture choices — without you re-explaining

Two background processes:

1. Daemon — polls ~/.claude/projects/ for transcripts, embeds chunks, runs distillation, analyzes feedback, compacts duplicates. All local.
2. Hook — fires on every prompt, recalls relevant memories, injects them as context. Sub-15ms.

No API keys required. Embeddings run locally via model2vec (potion-base-8M, 256-dim). Vectors stored in sqlite-vec. Everything runs on your machine.

Hybrid Scoring

Memor doesn't just match keywords. Each memory is scored by four signals:

Signal	Weight	How it works
Semantic similarity	50%	Vector cosine distance between query and memory
Recency	25%	Exponential decay with 14-day half-life — recent decisions rank higher
Kind weight	15%	Distilled memories (1.3x) rank above raw session chunks (1.0x)
Quality	10%	Bayesian score from implicit feedback — memories the agent actually uses rank higher

This means a relevant decision from yesterday beats a vaguely-related chunk from a month ago — even if the raw embedding similarity is similar.

Feedback Loop

Memor tracks whether recalled memories actually get used by the agent. After each session, the daemon analyzes the transcript to detect if recalled content appeared in the agent's responses. Memories that consistently prove useful get quality boosts; memories never recalled in 30+ days get automatically deactivated. Near-duplicate memories are compacted into one.

---

What Gets Stored

Kind	Source	Description
session_chunk	Daemon auto-ingest	Filtered turns from Claude Code transcripts
memory	Extractive distillation	Key decisions, patterns, bugfixes per session

Memories are automatically classified as decision, bugfix, lesson, snippet, or generic extract based on content patterns. The daemon runs a signal filter that keeps decisions, bugfixes, lessons, and code rationale while skipping noise (tool calls, file listings, boilerplate).

Dashboard

memor dashboard

Shows:

• Memory bank — session chunks, distilled memories, projects tracked
• Context efficiency — overhead %, recall precision, quality scores per session
• Per-project breakdown — which projects have the most context
• Recent recalls — every hook event with scores, latency, and status

Security

Nothing leaves your machine. In the default configuration:

• No telemetry, no analytics, no phone-home. Zero outbound network calls.
• Embeddings run locally via model2vec ONNX (one-time model download from HuggingFace — no user data sent).
• Hook transport is a Unix socket (~/.memor/hook.sock), not a network port.
• Dashboard binds localhost only.

The only optional network paths are the LLM-based abstractive distiller (requires explicitly setting ANTHROPIC_API_KEY) and the API embedding backend — both off by default.

Secret redaction

Memor automatically redacts secrets at ingest, before anything is embedded or stored:

• API keys (AWS AKIA..., OpenAI sk-..., Anthropic sk-ant-..., GitHub ghp_..., Stripe, Slack)
• JWTs, PEM private key blocks
• Connection strings (postgres://, mongodb://, redis://, etc.)
• .env-style assignments (DB_PASSWORD=..., API_KEY=...)
• High-entropy tokens (Shannon entropy > 4.0, length > 20)

Redacted content is replaced with [REDACTED] in place, preserving surrounding context. To audit and clean an existing database: memor scan (audit) or memor scan --purge (redact in place).

Contradiction handling

When a new memory contradicts an older one in the same project (detected via replacement cues like "switched from X to Y", "no longer", "ripped out"), the older memory is automatically deactivated. This prevents stale decisions from being recalled and misleading the agent.

Local storage

The memory database (~/.memor/memor.db) is stored as plaintext SQLite on disk. For at-rest protection, we recommend enabling OS-level full-disk encryption (FileVault on macOS, LUKS on Linux) which covers all local files with zero performance overhead.
