    Fern handles the rest. Daily check-ins, weather, reminders.

What Fern does.

A short list. Each one came from a real moment when a real plant needed help.

Knows your weather

Outdoor plants get a forecast-aware check. Rain coming? Skip the watering. Heatwave? Maybe move them.

Remembers everything

What you told it last week, last month. Where each plant lives. When you last watered the rosemary.

Identifies species

Say "the spiky one in the kitchen" and Fern figures it out. No Latin names required.

Morning digest

One message a day, your time. What needs water, what's overdue, what to skip. That's it.

Honest about uncertainty

When Fern doesn't know — no readings, never watered — it says so. It doesn't make up sensor data.

Reminders that fit you

Pick a time. Change it whenever. Turn it off when you're away. Your schedule, not the bot's.
