Frequently Asked Questions

Everything you need to know about BluePen AI. Last updated: 27 March 2026.

General

What is BluePen AI? +

BluePen AI is a screen-free AI tutoring system. It pairs a Bluetooth-enabled smart pen with a companion mobile app. Students click the pen, ask a question aloud in their own language, and receive an instant, curriculum-aligned audio explanation through their earphones, while writing in their own notebook. No screen time, no distractions.

Who is BluePen AI for? +

Students from Class 6 to Class 12 who need after-school study support. It is also suitable for university students and professional exam candidates. Parents, teachers, schools, and NGOs can all use it.

Which boards and curricula are supported? +

Currently supported: Maharashtra State Board, CBSE, and Telangana State Board for Classes 6 to 12.

Coming soon: German Lehrplan (by Bundesland), ICSE, and Karnataka State Board.

Which languages are supported? +

English, Hindi, Telugu, and Kannada at launch. German language support is in active development for our European users. The app includes automatic language detection, so students can speak in any supported language and the AI responds accordingly.

Product & Hardware

What's included in the BluePen AI kit? +

The kit includes: one BluePen AI Bluetooth pen with built-in microphone and earphones, a quick-start guide, and a USB charging cable. The companion app is a free download from the App Store and Google Play.

How does the pen connect to my phone? +

The pen connects via Bluetooth Low Energy (BLE). Open the BluePen AI app, tap "Pair Pen", and follow the on-screen instructions. Pairing takes less than 30 seconds.

Does the pen need to be charged? +

Yes. The pen charges via USB-C and lasts approximately 8 to 10 hours on a single charge, more than enough for a full evening of study.

Does it work without the internet? +

A basic mobile data connection (3G or above) or Wi-Fi is required for AI processing, as the tutoring responses are generated in real-time. The app is optimised for low-bandwidth connections in remote locations.

What are the 4 AI teacher personas? +

Exam Saviour: Focused on exam preparation, revision, and answering in the format expected by board examiners.

Concept Cracker: Explains difficult topics from scratch in simple terms with examples and analogies.

Task Master: Helps complete homework and assignments step-by-step, guiding without giving away answers directly.

Testing Coach: Runs MCQ practice sessions with scoring, timing, and explanations for wrong answers.

Is the content accurate and aligned with my child's textbook? +

Yes. Content is mapped to the exact syllabus and textbook chapters for each supported board. We upload official textbook PDFs and train the AI to respond strictly within the curriculum. The AI does not generate generic internet answers, it teaches what is in the student's book.

Does the AI remember previous questions? +

Within a session, yes. The AI maintains context so follow-up questions work naturally. Between sessions, the AI does not retain conversation history, but the app tracks which topics and chapters the student has studied.

Parents & Monitoring

How do parents track their child's progress? +

Parents receive a WhatsApp notification after every study session, including the subject studied, duration, and topics covered. The app also provides a parent dashboard with weekly progress reports, study streaks, and areas where the child needs more support.

Can parents control which subjects or topics are available? +

Parents can set the class, board, and subjects during setup. Content is restricted to curriculum-aligned material only. The AI cannot be used for non-educational purposes.

Is there any way for my child to access inappropriate content? +

No. BluePen AI is strictly curriculum-focused. The AI is trained to respond only to educational queries within the student's syllabus. Any off-topic or inappropriate queries are politely declined by the AI. There are no chat features, social networking, or user-generated content in the app.

Privacy & Security

Is my child's data safe? +

Yes. All data is encrypted in transit (TLS 1.2+) and at rest (AES-256). Voice queries are processed in real-time and are not permanently stored on our servers. We do not sell, share, or use student data for advertising. See our full Privacy Policy for details.

Are voice recordings stored? +

No. Voice queries are streamed for real-time processing and discarded after the AI response is generated. We do not store audio recordings or create voice profiles.

Does BluePen AI comply with data protection laws? +

Yes. We comply with India's Digital Personal Data Protection Act (DPDPA) 2023 and are designed to meet GDPR requirements for our European users. We do not engage in behavioural advertising or profiling of minors.

Technical & Troubleshooting

Which phones are compatible? +

BluePen AI works on Android 8.0+. The phone must support Bluetooth Low Energy (BLE), which includes virtually all smartphones made after 2016.

The pen is not connected to my phone. What should I do? +
  • Make sure Bluetooth is turned on and the pen is charged.
  • Open the BluePen AI app and tap "Pair Pen".
  • Hold the pen button for 3 seconds to enter pairing mode (the LED will blink blue).
  • If it still doesn't connect, restart both the pen and the app, then try again.
  • If the problem persists, contact gputech@trybluepen.com.
The AI is not responding or responding slowly. +

This is usually caused by a weak internet connection. Try switching from mobile data to Wi-Fi or moving to an area with better signal. If the problem persists, force-close the app and reopen it. If you continue to experience issues, contact gputech@trybluepen.com.

Can I use BluePen AI without the pen? +

The pen is the primary input device. However, you can also use the app's built-in voice button on your phone as a backup if the pen is being charged or is unavailable.
