Daylogue vs Harbour
Harbour makes one clear promise: a local AI that runs on your Mac, with your journal staying on your Mac and no account required. That is a real, principled choice. It is also a different product for a different person than Daylogue.
Harbour is best for
Mac users who want everything—journal, memory, and AI—running locally on one machine, with no account and nothing in the cloud.
Daylogue is best for
People who want a cross-platform pattern journal that reads their entries over time, detects emotional patterns, and follows you across devices, not just one Mac.
Feature comparison
One runs locally on a Mac. One reads your patterns across every device.

Where Harbour excels
For Mac users who want everything to stay on one machine.
Where Daylogue is stronger
For people who want patterns across their whole life, not just one Mac.
Works on every device
Harbour is a single Mac app that needs Apple Silicon and 16GB of RAM. Daylogue runs on your phone, the web, and more—so you can check in wherever you are, not only at your desk.
Pattern detection over time
Daylogue reads the emotional patterns running through your past entries and surfaces them in weekly, monthly, and yearly recaps. A local chat app can answer in the moment; Daylogue tracks how you change.
Frontier-model quality
Daylogue uses Claude-class models for cross-entry synthesis—the kind of longitudinal reading that small on-device models cannot match yet. The insight depth is the whole point.
Cross-device sync
Write on your phone in the morning, review patterns on the web at night. Your history stays in one place. Harbour keeps everything on one Mac.
Voice and guided capture
Talk through your day, or answer a gentle prompt. Daylogue lowers the barrier for people who freeze at a blank page—no writing skill required.
Clear about what it reads
Entries are protected in transit by TLS and by per-user access controls in the database. Daylogue reads them to write your narratives. Entry text is kept out of Daylogue's application logs and error reports, and AI processing runs transiently through AWS Bedrock, which does not store your content or train on it.
Privacy philosophy comparison
Harbour and Daylogue share a core belief: your private thoughts should stay private. They reach it from opposite directions.
Where they align
Harbour approach
Local-only. The model and your journal live on one Mac and never touch a server. Maximum data minimization, bounded to a single Apple Silicon machine.
Daylogue approach
Cloud-based, and honest about it. Entries are protected in transit by TLS and by per-user access controls in the database, and Daylogue reads them to write your narratives. Entry text is kept out of Daylogue's application logs and error reports, and AI processing runs transiently through AWS Bedrock.
If you want your writing to never leave one Mac, Harbour is the purist, local-only choice. If you want pattern insight that follows you across devices and over months, that requires a service that can read what you wrote. Daylogue is built for that, and says so plainly.
Common questions
Does Harbour work on iPhone or Windows?
No. Harbour is a macOS-only app and requires an Apple Silicon Mac with enough memory to run a local model. If you want to journal on your phone, on the web, or on a Windows machine, Harbour is not built for that. Daylogue runs across devices and keeps your history in sync.
Which is more private?
Both take privacy seriously, in different ways, and Harbour is the stricter one. Harbour keeps everything on your Mac and never sends your writing anywhere. Daylogue sends it to a server and reads it, because that is how the narratives get written. Entries are protected in transit by TLS and by per-user access controls in the database, entry text is kept out of Daylogue's application logs and error reports, and AI processing runs transiently through AWS Bedrock, which does not store your content or train on it. If you never want your writing to leave your machine, Harbour is the right choice.
Does Daylogue run its AI locally on my Mac?
Not today. Daylogue uses cloud models (Claude via AWS Bedrock) because they read patterns across months of entries far better than a local model can right now. Entries are protected in transit by TLS and by per-user access controls in the database, the AI request carries no name or email, and content is never retained or used for training.
Can I use Daylogue on more than one device?
Yes. Daylogue works on iOS and the web with cross-device sync, so your check-ins and patterns travel with you. Harbour is a single-Mac experience by design.
Which has better long-term insight?
Daylogue. It is a pattern journal built to read your past entries and detect the emotional patterns running through them, then surface those patterns in recaps over weeks, months, and years. Harbour offers local AI chat, but longitudinal pattern detection is exactly what Daylogue is designed for.
Is Harbour a subscription?
No—Harbour is a one-time purchase. Daylogue has a free tier and a subscription for premium features. Different models: pay once for a local Mac app, or subscribe for an evolving cross-platform pattern journal.
