Lochless

Lochless is a hosted text index for agents. Send your documents to Lochless through its API, then ask in plain English. Instead of returning the closest few results, it reads the documents in scope, up to a spend limit you set, and returns every relevant one as a quote with its document id and date. Or it writes a short answer that cites them.

Use it for questions like "every customer who asked for a refund this quarter", "which contracts auto-renew with under 30 days' notice", or "what did we promise about the SSO rollout".

Four read-only tools: search_documents, browse_documents, read_document and ask_documents. Browsing and reading a document are free. Searches and answers report how much text was read and whether coverage is complete. A free dry run shows the price before a query runs.

For your own documents, sign in with Google at https://console.lochless.io. Your workspace opens right away with $5 of free credit. No card needed.
