What the repository lets you verify
The source shows where photo assets are requested, how images and text become embeddings, how those embeddings are stored, and how a query is ranked. That makes the core data path inspectable instead of asking users to rely only on a marketing statement.
It also exposes practical engineering trade-offs: initial indexing can be demanding, iCloud assets may fail to fetch, large libraries need careful memory handling, and similarity models sometimes return imperfect matches.

What the MIT license permits
The MIT license is permissive: developers can use, modify, distribute and study the covered source subject to its short notice and warranty terms. Model files and Apple frameworks can have their own terms, so the repository license should not be treated as a blanket license for every external dependency.
Open source also does not mean the App Store binary is free of charge. Queryable is currently sold as a one-time paid app; purchasing supports the maintained release while the public code remains available for inspection and learning.
How to evaluate or contribute
Start with the README and license, then trace the photo-search view model into the image encoder, text encoder, embedding store and GPU search implementation. When reporting a bug, include the device model, iOS version, approximate library size, iCloud setting and a reproducible sequence without attaching private photos.
Contributions should preserve the app’s privacy model and be measured on real-device constraints. A feature that works on a tiny simulator library may behave very differently with tens of thousands of iCloud-backed assets.
What open source does—and does not—prove
Public code makes review possible; it does not guarantee that every line has been audited or that every build is free of defects. Users should still review App Store privacy information, requested permissions and network behavior.
For Queryable, open source is strongest as corroborating evidence: the published architecture is consistent with an on-device semantic search design, and the core implementation can be challenged or improved in public.
Common questions
Where is Queryable’s source code?
The official public repository is github.com/mazzzystar/Queryable.
Can I build my own version?
The covered source is MIT-licensed, but you must follow Apple developer requirements and the separate terms of any models or third-party assets.
Why pay for an open-source app?
The App Store purchase provides the maintained, signed distribution and supports ongoing development. Open source and paid distribution are compatible.
