~/.supermemory/env, which is loaded on every launch. You can also set variables in your shell or a process manager.
Core
LLM providers
In production, Supermemory uses its own proprietary models tuned for long-horizon data understanding. Self-hosted, you bring your own LLM for the intelligent steps — summaries, contextual chunking, and memory extraction. Embeddings default to a local model (no API key) and can optionally use OpenAI, Gemini, or Ollama — see Embeddings. Configure at least one LLM provider:
With multiple providers configured, the first one in the order above is used.
Image, video, and high-fidelity PDF understanding require a Gemini or Vertex AI key. Text ingestion, memory extraction, and search work with any provider.
Fully offline with local models
OPENAI_API_KEY + OPENAI_BASE_URL covers any OpenAI-compatible endpoint: Ollama, LM Studio, vLLM, llama.cpp server, Together, Fireworks, and more.
File storage
Nothing to configure. Uploaded files (PDFs, images) are stored on local disk inside$SUPERMEMORY_DATA_DIR and served by the server at /files/:key.
Embeddings
By default, vectors are computed locally withXenova/bge-base-en-v1.5 (768d) — no embedding API key. On interactive first boot you can pick a different provider after the LLM key step; for Docker/CI set env vars instead.

Embedding performance
Local embeddings are prewarmed at startup with conservative defaults — one worker, minimal CPU footprint. Turn these up if you’re ingesting heavily and prefer throughput over headroom:Memory limits & ingestion queue
The server manages memory for you and separates the two kinds of work you send it:- Searches are always served immediately. They never wait behind ingestion, regardless of how much is queued.
- Adds are accepted instantly but processed through a queue. A
POST /v3/documentscall returns in milliseconds with statusqueued; extraction, embedding, and indexing happen in the background at a controlled pace.
SUPERMEMORY_EMBEDDING_RAM_LIMIT (default 1 GB) above its post-boot baseline. Past that, new documents simply wait in the queue until memory drops back under the limit — nothing is dropped, ingestion just slows down. The limit is measured above the boot baseline because the built-in local embeddings and storage engine have a fixed footprint that exists before any document is processed.
The limit is printed at boot, and whenever adds are waiting the binary shows a live status line in the terminal:
Telemetry
The self-hosted binary sends no analytics — there is nothing to opt out of. The only related switch:Platform-only features
These exist in the codebase but are exclusive to the hosted platform — the self-hosted binary doesn’t include them:- Connectors — Google Drive, Notion, Gmail, OneDrive background sync
- Supermemory MCP — managed MCP server endpoints
- Optimized memory extraction — the platform’s extraction pipeline is tuned for higher quality at lower cost than bring-your-own-key
- Managed scale — globally distributed infrastructure, no capacity planning
