Show HN: SuperLocalMemory – Features Jev/Laya as Judges on Every Recall

Qualixar released SuperLocalMemory (SLM), a local-first long-term memory tool for MCP clients including Claude Code, Codex and Cursor, installable via `npm install -g superlocalmemory` on Node 18+ and Python 3.12+, or `pipx install superlocalmemory`. SLM stores facts in SQLite on the user's disk, supports temporal queries with `--valid-at` and `--known-as-of`, fact replacement via `--replaces`, and an optional answer check that flags when top results do not answer the question. It runs on Apple Silicon macOS, 64-bit Windows and 64-bit Linux, requires no Docker, graph database or API key, and connects to 12 IDEs through `slm connect <ide>`.

Claude Code, Codex, Cursor and other MCP clients lose what they learned when a session ends. SuperLocalMemory SLM gives them one long-term memory that lives on your machine, and it can tell you when it doesn't have the answer instead of guessing. npm install -g superlocalmemory primary route Node 18+, Python 3.12+ ; or: pipx install superlocalmemory slm setup pick Mode A to keep everything on this machine slm connect cursor or claude-code, codex, windsurf, zed ... 12 IDEs npm installs SLM into a package-owned virtual environment. The other primary route is pip in a Python virtual environment you activate: python3 -m venv .venv , activate it, then python -m pip install superlocalmemory . Repository clone: ./scripts/install.sh install macOS, Linux or .\scripts\install.ps1 -Action Install Windows ; see CONTRIBUTING.md https://github.com/qualixar/superlocalmemory/blob/main/CONTRIBUTING.md .

Real output from a fresh Mode A install, trimmed. The id comes from slm recall --json . Scores are ranking signals, not probabilities. Right after a start, the embedding model is still loading: recall still answers from keyword and time channels and says Incomplete search until the model is ready. - Local-first by default. Memory lives in SQLite on your disk. In Mode A, core remember and recall make no model-provider call. Anything that sends data out is a choice you make, and the docs say exactly what goes. - It says "I don't have that." The optional answer check https://github.com/qualixar/superlocalmemory/blob/main/docs/answer-check.md judges whether the top results actually answer the question, on your Mac or through Jev, and flags it when they don't. - Memory with a sense of time. Every fact records when it happened and when SLM learned it. Ask what was true last month --valid-at , or what SLM knew before a date --known-as-of . Replaced facts stop being served as current. - One memory, every agent. The same store serves Claude Code, Codex, Cursor, Windsurf, Hermes and any MCP client, so a decision saved in one tool is there in the next. SLM is part of Qualixar's AI Reliability Engineering work: agent memory that is observable, bounded and honest about what it doesn't know. | Surface | What you get | Docs | |---|---|---| | Editor plugins | Claude Code, Codex, VS Code / Copilot, Antigravity, Hermes.

An unknown profile name stops startup and lists the valid ones. Relevance and "does this answer it" are different questions. The closest memory on file can still be the wrong answer, and an agent that treats it as the answer makes things up with confidence. Answer check adds a second step after ranking. It reads the top results and decides whether they answer the question. Choose one, in Settings → Answer check in the dashboard: - On this Mac Laya : a small model, about 1.1 GB, on Apple Silicon. Nothing leaves the machine. - Online with Jev: TypeSafe or OpenRouter, with your own key and an explicit consent box. Sends the question and the top 3 memories. - Off. Only one runs at a time, and nothing turns the online option on by itself. Each option shows whether it is ready, has a Test button, and is applied live with one Save . Results are never hidden: recall returns them with abstained and abstention reason set, and your agent decides what to do. The same question gets the same verdict on a repeat. The Answer Check tab shows each verdict, its timing against the 3-second recall ceiling, and how often it said "I don't have that" over 24 hours, 7 days or 30 days. The history keeps outcomes and timings, never your questions or memory text. What leaves your machine, and when: | Data | Leaves only when | |---|---| | Recall question and top 3 memories | You turn on the online answer check Jev and tick its consent | | Question and top 20 memories | You also turn on Jev reordering, which has its own notice | | Memory text | You choose Mode C, a cloud embedder or reranker, an Ollama on another computer, or Jev kind typing its own consent | | Encrypted backup files | You connect GitHub or Google Drive backup. Files are encrypted before upload | | Mesh messages | You configure SLM-Mesh peers | Model downloads embedding model, Laya fetch files but send no memory content. Credentials found in memory text are redacted on every outbound path, and a provider's key goes only to that provider. Since 4.1.20, other computers must authenticate to read memory, not only to write it. SLM ignores forwarded-for headers unless you name a trusted proxy, so a proxy can't make a remote caller look local. SLM's own outbound requests never follow redirects, and the remote listener never answers with one, so a key is never sent through a redirect. Remote callers never see this computer's paths, account or environment outside the memories themselves. Remote agents connect through slm remote : TLS only, one named key per client, each key bound to one profile its holder reads that profile's memories in full and nothing else , read-only keys available, and slm remote keys revoke <name takes effect on the next request.
