Lightweight Local Search Engine Need
Problem
Current mainstream search tools (e.g., macOS Spotlight) consume high resources, perform poorly, and fail to meet localized, low‑power requirements. Users want an efficient, locally‑run search and reasoning engine for fast, private content retrieval, especially in learning and content‑adaptation contexts.
Pain points
- Existing search systems hog resources, drain power, and respond slowly
- Lack of a lightweight search engine that can run locally and support reasoning capabilities
- Users need to dynamically retrieve content suited to their skill level, which current tools cannot provide
Questions to verify
- Would users be willing to pay for such a local search tool?
- What specific scenarios currently dominate users' search needs (e.g., learning, file management)?
- What are users' main complaints about existing search tools?

Before joining the team I started developing a comprehensible input curation engine for my own language learning purposes built on Antfly.

Yeah open question what "perfect" search would even be, like would that just end up being indistinguishable from a kind of magical omniscience? And then there's "can I literally just find that one freaking slideshow from a while ago with that one client... or is it in Google Drive...?" And I really don't want the solution to be that we just plug everything into Claude

I've actually been using this to build a local file search agent. I started building it on the Go version of Antfly, but the new Zig runtime is a huge improvement (better resource utilization, reliability, recovery, ...)Anyone who has used Spotlight search on macOS knows that (1) it can be an absolute resource hog, and (2) it's relatively useless (even with Siri stuff they added in macOS 27). So I was eager to take a stab at a native app that did both better and kept everything on-device (no external inference providers), and building it on Antfly meant I could run it all from one engine (way simpler to coordinate than a whole RAG pipeline).
