ELI5
Understand complicated things without the complicated explanation.
Ask about a topic, paste something confusing, or check whether you understand an idea correctly. ELI5 breaks difficult concepts into approachable language and lets you keep asking questions until the idea makes sense.
Choose a broad explanation when you want context, keep it condensed when you only need the essentials, and optionally include learning resources for deeper exploration.

More than a one-shot answer
ELI5 is built for understanding. Start simple, ask follow-up questions, test what you think you know, and keep the explanation focused on the level of detail you actually need.
Check your thinking
Explain what you think is happening and use ELI5 to identify what you've understood correctly and what may need another look.
Keep asking
Follow up when part of an explanation still doesn't click instead of starting over from scratch.

Include optional learning resources when you want places to continue reading after the explanation.
Step 1
Ask or explain
Ask a question, describe a topic, paste confusing material, or tell ELI5 how you currently understand the idea.
Step 2
Choose the depth
Get a broad explanation with context or keep the answer condensed when you only need the essential idea.
Step 3
Keep going until it clicks
Ask a follow-up question and build on the explanation instead of losing the context you've already established.
