Have you ever missed a class or meeting because a WhatsApp message slipped your mind? Or double-booked yourself after manually entering a rescheduled email? We've all been there. Schedule Sensei is an Android app being built to solve this problem—automatically extracting event details from your notifications and adding them to your calendar, all while keeping your data private on your device. Below, we answer common questions about how it works, what's supported, and how you can help shape its development.
1. What specific problem does Schedule Sensei solve?
Schedule Sensei tackles the daily hassle of manually tracking time-sensitive messages from apps like WhatsApp, Gmail, and SMS. When you receive a notification such as “Tomorrow's class is shifted to 10 AM” or “Meeting rescheduled to Friday at 3 PM,” the app uses on-device natural language processing (NLP) to automatically extract the date, time, title, and location. High-confidence events are added directly to your calendar, so you never forget or mis-enter an appointment. For ambiguous messages, the app alerts you with a custom sound to review a pending event. The goal is to eliminate reliance on fallible human memory and tedious manual calendar entry.
2. How does the app work step by step?
After a one-time setup where you grant notification access, Schedule Sensei runs silently in the background. When a message arrives (e.g., “Team sync tomorrow at 2 PM”), the app detects it, extracts the key details using NLP, and assesses confidence. If confidence is high, it automatically creates a calendar event and sends a silent confirmation (which you can disable in settings). If the message is vague, like “Maybe the schedule changed?” the app considers it low confidence and plays a custom sound, showing a pending event for you to manually review and confirm. All processing happens entirely offline, and the app never sees your full chat history—only notification content.
3. Which messaging apps and services are supported initially?
Schedule Sensei is being built to support WhatsApp, Gmail, and standard SMS out of the box. The developer is actively seeking community feedback on expanding support to Telegram, Signal, Instagram, and others. Because the app works by reading notification content, it can in theory support any app that sends text notifications. However, each integration may require optimization for different message formats. Users can also disable monitoring per source—for example, choose to auto-scan WhatsApp and Gmail but ignore other apps.
4. How does Schedule Sensei protect my privacy?
Privacy is a core design principle. All event extraction and processing happens entirely on your device—nothing is uploaded to the cloud or sent anywhere. The app only reads the content of notifications as they appear, not your full chat history or message logs. You retain full control: you can turn off notification access at any time, or disable monitoring for specific apps (e.g., WhatsApp only, Gmail only). Additionally, the code will be open source, allowing anyone to audit it for security and privacy compliance. This approach means your sensitive messages never leave your phone.
5. How does the app decide whether to auto-add an event or ask for review?
Schedule Sensei uses a confidence scoring system based on the clarity and completeness of the event details in each message. If the NLP model extracts a clear date, time, and event title (like “Team sync tomorrow at 2 PM”), the confidence is high, and the event is added automatically. If the information is ambiguous, incomplete, or uses vague language (e.g., “Maybe the schedule changed?”), the confidence is low. In such cases, the app does not auto-add anything; instead, it notifies you with a custom sound to open the app and review the pending event. This lets you decide whether to manually confirm, edit, or dismiss the entry.
6. Can I customize how Schedule Sensei behaves?
Absolutely. The app includes several settings to tailor its behavior to your preferences. You can disable auto-add for all events, so nothing is added without your explicit confirmation. You can also choose to receive a silent toast notification instead of a full confirmation. For per-app control, you can enable or disable monitoring for WhatsApp, Gmail, SMS, and any future supported apps individually. Additionally, you can set a custom notification sound for low-confidence alerts. The developer plans to add more options based on user feedback, such as whitelisting certain contacts or ignoring events from specific senders.
7. What edge cases are being considered (like multiple dates or recurring events)?
The developer is actively working on handling tricky scenarios. For example, a message may mention multiple dates: “Meeting on Monday and Wednesday at 3 PM.” Schedule Sensei will treat such messages as low confidence and ask you to review and create separate events. For recurring events, the app can detect phrases like “every Tuesday” and prompt you to set a recurring calendar entry. Time zones, relative dates (e.g., “next Friday”), and location names (like “Conference Room B”) are also being parsed. Community feedback is crucial to improve these edge cases, and the developer encourages users to report any missed patterns.
8. How can I contribute feedback or suggest features?
The project is in early development, and community input is highly valued. You can share your thoughts on which messaging apps should be supported (e.g., Telegram, Signal), privacy concerns that would make you feel safer, and any edge cases you've encountered. The developer is also considering a manual forward fallback method—where you share a message directly to the app for processing—so even if notification reading isn't possible, the app can still help. To get involved, follow the project's early posts and provide comments. Your suggestions will directly influence the roadmap and feature set of Schedule Sensei.
