# Paicer - AI-Powered Workout Sync for Garmin

## Product Description

Paicer is a web-based application designed for runners who want to get structured workouts onto their smartwatch without manual data entry. The core innovation is AI-powered workout image parsing: users upload a screenshot of any workout (from coaching apps, PDFs, social media, text messages, or handwritten notes), and Paicer's AI extracts the workout structure (intervals, distances, durations, pace targets, rest periods) and syncs it to your watch. Currently supports Garmin®, with Coros, Polar, and other providers coming soon.

## Problem Solved

Runners commonly receive workouts from sources that don't integrate with Garmin Connect™:
- Coach emails or messages with workout descriptions
- Training plans purchased as PDFs
- Social media workout posts
- Screenshots from apps that don't sync to Garmin Connect™
- Handwritten plans from local running clubs

Previously, these workouts required manual entry into Garmin Connect™, a tedious process for complex interval sessions. Paicer eliminates this friction entirely.
