Heartlines works by letting you jot down small details about people as short private notes, organizing them into per-person profiles, and making them searchable so the right detail resurfaces exactly when you need it.
Heartlines works by letting you jot down small details about people as short private notes, organizing them into per-person profiles, and making them searchable so the right detail resurfaces exactly when you need it.
Heartlines follows a straightforward rhythm. You capture a detail the moment you notice it, Heartlines organizes it under the right person, and later you recall it through search or reminders. The whole point is to close the gap between hearing something meaningful and being able to act on it weeks later.
Heartlines runs in your browser and installs as a PWA, so it feels like a native app on your phone or desktop. Your notes are stored privately and isolated to your own account, never shown to other users and never sold. If you enable the optional AI, it processes only what you choose and never trains external models on your data.
Heartlines helps by making the capture step effortless and the recall step reliable. Because writing a note takes seconds and finding it takes one search, thoughtful follow-through stops depending on your memory. The whole workflow, including the optional AI, is free during the current launch, with a paid plan for heavier AI usage planned for later.
Sign up, create a profile for someone you care about, and start adding notes. Heartlines makes each note searchable so you can recall the right detail later, and you can install it as an app on your phone or computer.
Your notes in Heartlines are private and isolated to your own account. They are never shown to other users, never sold, and never used to train external AI models.
