## What is CtxLens?

Captured. Linked. Secured.

Where notes and photos become a record.

• Capture in seconds. A card holds text, up to 12 photos, GPS, group, subgroup, and up to 24 tags — all from one screen, no setup required.

• Two-tap capture from the Lock Screen. Widget actions for Camera, Compose, and Activities.

• Photos linked to text, both directions. Every image in your report carries an ID; every reference in the AI summary points back to the photo it describes.

• On-device AI summary, narrative or bullets. Apple Intelligence consolidates state-change entries and references your photos inline. Nothing leaves your phone.

• Custom terminology, app-wide. Rename "Group" and "Subgroup" to whatever your work calls them — Address, Project, Client, Asset. The terms propagate everywhere, including the final reports.

• Activities and countdowns inside your timeline. Tracked start, pause and stop times, with the ability to attach photos and add notes at every state change, alongside the rest of the day's record.

• Arrange the report your way. Numbered Sort Order lets you set the exact sequence your cards appear in the final document.

• Multi-format export. PDF, DOCX (Word, Pages, or Google Docs) or structured JSON. Generated on your phone, ready to share.

• AI-ready PDF export, optimized for context engineering. Image references and structure preserved, with a structural overview that primes the AI before the first card. Feed it to a multi-modal AI to populate templates, generate reports, or answer questions about your fieldwork.

• Map cards (including photos) in Google Earth, ArcGIS, and other GIS platforms.

• Full-text search. Every word of every card, indexed and instantly searchable.

• Privacy by design. Your data stays on your phone. No cloud. No server.

• Hand off a packet of cards to a colleague. Selected cards, photos, and even running activities or countdown timers over AirDrop, Messages, or email. No sever. No shared account, and no IT.

• Aggregate your team's work into your own database. Each user's card collection exports as structured JSON, ready to import into a database or analytics tool.
