InlineDoubt

About

InlineDoubt lets you ask doubts about any specific 
line in an AI answer — without opening a new tab, 
without scrolling, without losing your place.

HOW IT WORKS:
→ Hover any line in an AI chat answer
→ A bubble appears on the right side of that line
→ Click it, type your doubt in plain English
→ AI explains that exact line — right there, inline

FEATURES:
✓ Figma-style comment threads on every line
✓ Ask follow-up questions in the same thread
✓ Mark doubts as Resolved when you understand
✓ Add your own notes to any AI answer
✓ All doubts saved in the right sidebar panel
✓ Click any saved doubt to jump back instantly
✓ Remove or edit any doubt anytime

On Claude.ai and Perplexity, InlineDoubt uses your 
existing login session directly — no setup, no API 
key, unlimited and free.

On ChatGPT, Gemini, DeepSeek, Grok, and Meta AI, it 
uses a free API key you can generate in about 30 
seconds — no card, no subscription, never expires.
