Train custom vision AI on your iPhone — no code, no data science degree.
Collect a custom image dataset with your iPhone camera and train a vision classifier right on the phone, with no cloud round-trip and no code.
Every misclassification can be corrected in place, letting the model improve iteratively as you keep using it in the real world.
Assign HomeKit lights, outlets, fans, or scenes to specific categories so that recognizing an object in the camera view instantly brings up the matching controls.
Take your trained classifier beyond FieldDay and reuse it in Siri Shortcuts, Snap Lens Studio, Xcode, and other popular formats and tools.

Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
