ContempoHours that survive an audit

An AI-native log for short-term-rental hosts tracking the IRS material-participation tests: say what you did on your phone or watch, and Contempo turns it into a contemporaneous, risk-checked record.

Capture hands-free

Voice on the phone or the watch, typed quick capture, start/stop timers, GPS mileage trips and photos; on-device Whisper and an on-device LLM parse it, with a cloud fallback.

Audit-ready records

Every entry carries when it happened and when it was logged; vague or backfilled entries are flagged before they become a problem.

A copilot that knows the rules

Ask whether something counts, grounded in IRS Pub 925 and §1.469-5T and your own logged hours — with clear limits, not tax advice.

How it fits together

Each user's entries, properties, attachments and captures are their own rows (row-level security) and files (<uid>/… in a private bucket). Details: projects/contempo/CLAUDE.md.
