Heivol Contextbox

One knowledge base for every LLM setup. Your notes, documents, photos, and recordings live in a single self-hosted store — readable from Claude Code on your laptop, Claude Desktop, the Claude mobile app, OpenClaw, or any agent that speaks HTTP. Switch models or clients; your context stays with you.

What it does

Shared across every LLM client

Install the Claude skill on your laptop, point Claude Desktop at the MCP server, or paste a remote connector URL into the Claude mobile app. Same knowledge, same bearer token, same search results. Changing LLM runtime doesn't orphan your context.

Hybrid semantic + keyword search

Every query fuses dense vector similarity (pgvector HNSW) with BM25 keyword ranking (ParadeDB) in a single SQL call. ~70 ms end-to-end on a modest KB. Search fans out across every KB you have access to, with per-result citations back to the source.

Git-push ingest

Every KB is a bare git repo behind SSH. git clone, edit locally, git push — the server re-indexes changed files incrementally. Bulk-import an Obsidian vault, a recipe folder, or a research archive in seconds.

Share with your people

Per-KB membership with owner / editor / reader / search roles. One family recipe book, one household travel plan, one team research archive — all readable by the LLMs of every member, each on whichever client they prefer.

Programmable by design

HTTP API is the canonical contract; the skill, MCP server, CLI, and admin UI are thin clients over it. Mint, rotate, and revoke tokens programmatically. Every capability a human can do in the admin UI is an endpoint.

Self-hosted and yours

Runs on your own infrastructure — a Proxmox LXC, a VM, a laptop. Embeddings go through heivol-modelproxy so no LLM vendor ever sees your raw data. No training on your content. Ever.

Pricing

One plan, billed by storage. Twenty kroner gets you the platform plus your first gigabyte; each extra gigabyte is another twenty kroner. No per-search, per-query, or per-token billing.

Monthly

20 DKK / month

+ 20 DKK per extra GB-month above your cap

≈ €2.70 / mo · 25 DKK inc. 25% VAT (B2C)

  • 1 GB of storage included — aggregated across all your knowledge bases
  • Default cap is a hard limit; raise it any time from your Usage tab to opt into overage
  • Unlimited knowledge bases & members; share KBs with owner / editor / reader / search roles
  • Every access surface: Claude skill, MCP server, HTTP API, CLI, git push
  • Hybrid semantic + keyword search across every KB you can see
  • Self-hosted on Heivol infra — your content never trains a model

Storage is the only metered dimension. Bytes are summed across every KB you own (per-tenant aggregate, not per-KB). When multimodal lands — photos, audio, video — the same rule applies: 1 GB included, +20 DKK per extra GB.

Current status
