How it works

Four steps, zero context switching.

InlineDoubt sits on top of the page you're already reading — it doesn't take you anywhere else.

Select any context

Select any text in an AI answer you want explained.

02

Click the bubble

A small bubble appears on the right side of that exact line.

03

Type your doubt

Ask in plain English — follow-ups stay in the same thread.

04

Get it explained

The AI explains that exact line, right there, inline.
