Everything packed in
One extension. A whole AI toolkit.
Built for students, researchers, and professionals who move fast. Every detail is tuned for speed, accuracy, and zero friction.
Smart side-panel chat
A focused AI chat that docks beside any page with Alt+Shift+F. Streamed answers, code blocks, and full context of what you're reading.

Pulls fresh context from the web so answers stay current, not stuck in a training cut-off.
Image understanding
Drop in a screenshot or photo and ask about it: charts, diagrams, handwriting, equations.

Light and dark, by design
A glassy, premium UI that adapts to your system, easy on the eyes day or night.

Frequently asked
What exactly does ThinkPulse do?
It's a Chrome extension with three core powers: OCR text capture from any image on screen, a smart AI chatbot in a side panel, and automatic failover across multiple AI models so you always get an answer.
What is multi-API failover?
ThinkPulse can talk to several AI providers. If one is rate-limited, slow, or down, it automatically routes your request to the next available model, invisibly, so you never see an error.
How do I capture text from an image?
Press Ctrl + Shift + X and drag a box over the area, or right-click an image and choose the OCR option. Clean text is returned instantly.
Is my data safe?
Yes. Sign-in is handled securely via Google, permissions are scoped to what's needed, and your conversations and content are never sold.
What is exam mode?
For high-stakes accuracy, exam mode runs multiple models and compares their answers to surface the most reliable response.
How much does it cost?
ThinkPulse is free to add to Chrome. For any billing or usage questions, reach us at support@thinkpulseai.in.
