Common questions
What limitations apply?
Approximate only: UTF-8 bytes ÷ 4, rounded up. Not a model tokenizer; languages, code and models can differ substantially.
Is my input saved?
No. It stays in browser memory and clears on refresh. Successful actions record only a stable tool ID and name, never your entered data.
