Overview

Digger Solo is a local-first AI file explorer for macOS that lets you find documents, images, and PDFs by concept rather than filename. Semantic search understands meaning, so you can search for 'invoice from Berlin supplier' or 'non-disclosure agreement' without remembering exact wording. Semantic maps visualize how files cluster and relate. A built-in RAG chat lets you ask questions across your documents with cited answers. Duplicate detection catches near-identical files that exact-match tools miss. Everything runs on your machine — no cloud, no telemetry, no accounts required.

Pricing: Free up to 500 files | €49 one-time (unlimited) | €4.90/month

Minimum macOS: 13.0 (Ventura)

Architecture: Apple Silicon, Intel
