As developers, we often build tools for ourselves. But when we build with educators in mind, the impact can scale quickly.
Teachers juggle dozens of tasks—often without the right digital support. That’s where simple random generators shine: fast, free, and flexible for dozens of use cases.
Here are 5 random generators (including one we made) that educators will love.
🔡 1. Random Letter Generator
We built this tool to be dead simple. Just click and get random letters. Ideal for ESL teachers, creative writing prompts, phonics games, or just breaking the ice.
• Choose how many letters you want
• Allow or disallow duplicates
• Works on all devices
• Lightweight and fast
