Conversion Tool

OpenSet includes a self-contained LLM prompt that converts free-text workout descriptions into valid OpenSet JSON.

How It Works

The conversion prompt (tools/convert/prompt.md) contains everything an LLM needs:

• The full OpenSet structure and rules
• All valid dimension names and how they compose into sets
• All canonical exercise IDs from the default library
• Conversion examples showing free text to valid JSON
• Instructions for handling ambiguities

Usage

With Any LLM

1. Copy the contents of tools/convert/prompt.md
2. Paste it as a system prompt or initial context
3. Send the workout text you want to convert

Example

Input:

Bench press 5x5 at 100kg, then 3 sets of 10-12 dumbbell rows at RPE 8

Output:

          ]
        }
      ]
    }
  ]
}

Online Converter

An online version of the OpenSet converter is available at getdiby.com/openset. Paste any unstructured workout description and get valid OpenSet JSON back — no setup required.

Customization

You can modify the prompt to:

• Add domain-specific exercises
• Adjust default units (kg vs lb)
• Include sport-specific conventions
• Add custom dimensions via extensions
