Shlexball is a Mac app that finds files from a plain-English description, like "where are my github 2fa recovery codes". Its 1.5B model, fine-tuned from Qwen2.5-Coder-1.5B-Instruct, runs on your Mac and writes a search plan; a read-only sandbox runs it, so your files are never uploaded. It searches names, contents, PDFs and Word documents. macOS 15, Apple silicon, 16 GB. 30 free searches, then 9 USD a month or 59 USD a year.
