## What is Seren?

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.
