Your care companion for
chronic illness
An AI-powered conversation tool that helps you build structured medical documents through natural dialogue. Organize symptoms, track patterns, prepare for appointments, and create clinical summaries your providers can actually use.
Seven artifacts that tell your care story
As you talk with Throughline, it assembles structured documents called artifacts. Each one captures a different dimension of your care experience. Together, they form a complete framework you can share with providers, reference in appointments, or use to track your own progress.
Pattern Map
Tracks your symptoms, triggers, and how they change over time. Helps you and your providers spot connections that might be missed in a 15-minute visit.
Documentation Priorities
Identifies what needs to be in your medical record and what's currently missing. Helps you focus conversations with providers on the documentation that matters most.
Engagement Thresholds
Maps out how to communicate with each provider based on what works. Tracks communication styles, timing, and the approaches that lead to productive interactions.
Appointment Anchor
Builds structured preparation materials for upcoming appointments. Includes talking points, questions to ask, documents to bring, and follow-up items to confirm.
Decision Ledger
Records clinical decisions and their context. When a treatment was started, why, what alternatives were discussed, and what the expected outcomes were.
Amendment Request Guide
Walks you through the process of requesting corrections to your medical record. Helps you identify what's inaccurate and draft a clear, specific amendment request.
Navigator Framework
A unified view that assembles all six artifacts into a single, comprehensive care document. This is your complete framework, the full picture of your care story in one place.
Three modes for different moments
Throughline adapts to where you are in your care journey. Each mode focuses the conversation on a specific goal.
General mode
Open-ended conversation about your condition, history, and experiences. Talk about what's happening, and Throughline organizes it into your artifacts as you go. This is where most people start.
War Room mode
Focused preparation for an upcoming appointment. Throughline helps you identify what to discuss, what questions to ask, what documents to bring, and how to communicate your needs clearly.
Debrief mode
Process a recent visit. Talk through what happened, what was said, and what was decided. Throughline captures the details while they're fresh and updates your artifacts accordingly.
Documents you can actually send
Everything Throughline builds can be exported in formats that work for real healthcare workflows.
Portal messages
Pre-written messages formatted for your patient portal. Copy, paste, and send to your provider with the right clinical language and clear structure.
Clinical summaries
One-page summaries formatted for new providers or specialists. Contains your relevant history, current status, and context they need before your visit.
PDF exports
Branded PDF documents with proper headers, footers, and formatting. Print them, email them, or bring them to your appointment.
Your data stays in your browser
Throughline stores all of your care data in your browser's local storage. Nothing is saved to a server. Nothing is shared with anyone. If you clear your browser data, your Throughline data goes with it.
No accounts required
No email, no password, no profile. You open Throughline and start talking. Your data exists only on your device.
No data collection
We don't track usage patterns, store conversation logs, or build profiles. The AI processes your messages and responds. That's it.
You're in control
Export your data whenever you want. Delete it whenever you want. There's no lock-in, no data hostage situation, no "please don't go" popup.

Throughline includes specialized prompt bundles for several chronic conditions, with clinical knowledge tailored to each one. The general mode works for any condition, and we're adding new specializations regularly.
