Readigo: iOS App Uses Claude as AI Reading Coach for Kids

How Readigo Works

Readigo is an iOS app designed to help children practice reading aloud. Kids read stories into the device's microphone while interacting with an AI dragon character. The system uses speech-to-text to transcribe what the child says, then Claude compares the transcript against the source text to evaluate reading performance.

Claude's Specific Functions

• Scoring engine: Claude analyzes the transcript against the source text and returns structured scores for accuracy, fluency, pacing, and clarity.
• Feedback generation: Claude writes age-appropriate responses that are encouraging rather than corrective, calibrated to the child's specific age.
• Content adaptation: Claude adjusts difficulty and tone based on the child's reading level.

Development Insights

The developer found that getting the tone right for different age groups was the most challenging aspect. A 7-year-old who reads "cat" as "cap" needs a completely different response than a 12-year-old struggling with "necessary." Dozens of prompt iterations were required to make feedback feel like a supportive buddy rather than a teacher with a red pen.

Current Limitations

The app struggles with children who have regional accents where upstream speech recognition drops in accuracy before Claude even sees the text. This makes scoring feel unfair, and the developer hasn't found a clean fix yet. They're seeking input from anyone who has worked on speech-to-text for children or non-native speakers.

Availability

Readigo is available on iOS with a 7-day free trial. The app is free to try during this period.
