Questions, answered
Why does a plus sign remain a plus sign?
A plus represents a space only in form-style query encoding. This is generic component decoding, so + remains literal.
Does this send my input to a server?
No. This engine processes input locally without network requests. The surrounding website may have its own analytics or scripts; avoid entering sensitive material on an untrusted site. Text fields accept at most 1,000,000 UTF-16 units unless a smaller field limit is stated.
