Pulsar shapes every message around each participant's real-world data: their Fitbit steps, their weight from the scale that morning, their timezone, their response patterns, their place in the study. You define the rules once. Their data decides the rest.
One glance gives you the full picture. Enrollment, engagement, device compliance, and live activity are all available to you in real time.
Describe what you want. Ask what you need. Discover what you didn't know to look for.
Use our internal Anthropic engine to personalize messages based on each participant's journey. Your data doesn't go anywhere; our AI engine is built-in so your study remains secure. You review everything before anything is sent out, so you can let the computer do the grunt work while supervising and ensuring the best outcome for your study.
Ask questions in plain English. Get instant answers across messages, Fitbit, weights, and nutrition data. Save queries as live stats, export to CSV, or bookmark for quick access.
Mark any template for AI generation. Personalized content is written at the moment of delivery using real participant data.
Pulsar reviews your study daily and surfaces patterns across engagement, outcomes, and message content. Reports are delivered to your inbox weekly.
Everything you need to run sophisticated message-driven research studies.
Your roster is intelligently grouped by status. Filter by active, waiting, or finished participants. See weight trends, Fitbit sync status, and study day at a glance.
See your entire messaging plan laid out by study day. Color-coded topic dots show what fires when. Click any day to see the detail.
Pulsar detects problems before they become crises. Root-cause diagnosis tells you exactly why something failed - landline, carrier block, or missing device data - with inline actions to resolve.
Standard and AI-generated reports ready when you need them. Export history with timestamps for IRB compliance. Download CSV data for your own analysis.
Design sophisticated EMA and survey-sampling protocols with a guided visual wizard. No coding required.
Select how participants receive prompts: fixed schedule for evenly-spaced times, random schedule for unpredictable sampling, or threshold-based to fire when a health metric falls below a target.
Then walk through scheduling, message content, response windows, and skip conditions, all in a guided wizard. Review a plain-English summary before going live.
Define the prompts participants receive. Choose sequential delivery (in order) or random (a different message each time). Set messages to repeat after the pool is exhausted.
Add, edit, or reorder messages anytime. Each prompt can include survey-style questions that participants respond to directly.
Signal-contingent, interval-contingent, and event-contingent sampling. Random prompts within defined windows or fixed schedules.
Trigger surveys based on heart rate, step counts, or sleep data from connected wearables. Threshold-based prompting built in.
Respect individual sleep schedules. No prompts during sleep hours. Automatic adjustment per participant.
Native mobile notifications with configurable reminders. Response windows prevent stale data collection.
Define when to skip or delay prompts based on recent responses, sensor data, or inbound keywords. Delay or reset modes.
Real-time dashboards show response rates, completion times, and participant engagement. Spot declining patterns early.
