Seren is an AI companion that helps you track and reflect on everyday life with chronic pain. Record pain intensity and location, sleep, mood, exercise, medication, notes, and more. Instead of filling out every field one by one, you can simply talk with Seren and let AI help turn the conversation into your daily records. ■ EASY PAIN AND SYMPTOM TRACKING Record pain intensity and location along with sleep, mood, exercise, medication, notes, and other details about your day. You can choose which fields to show and arrange them in the order that works best for you. ■ TALK TO AI AND LET IT HELP YOU RECORD "I have a headache today and didn't sleep very well." Talk naturally with Seren, and AI can help organize what you said into your records. It can also help you look back on past records and notice patterns or changes that may be worth reviewing. Both text and voice input are supported. ■ REVIEW AND SUMMARIZE Look back on your daily records or create summaries for periods you want to review. --- Seren is free to use. For people who want to use AI more frequently or support the continued development and operation of Seren, an optional monthly Supporter Plan provides a higher AI usage limit and an in-app supporter badge. ※ Seren is not a medical device and is not intended to diagnose, treat, or prescribe medication. ※ AI responses are for informational purposes only. If you need medical advice or a medical assessment of your symptoms, please consult a qualified healthcare professional.
