Every plant, thriving.
Because now you know what it needs. Snap each plant and Fernfriend names it, reads your window and your season, and gives it a care rhythm of its own. When a leaf looks wrong, snap that too.

how it works
Three steps, one path.
You do the snapping. Fernfriend does the knowing.
- station 01
Snap your plants
One photo each. Fernfriend names the plant, tells you how sure it is, and asks which window it lives by and how close. That is the whole setup.
- station 02
Get each one's rhythm
Water, light, feeding, and repotting, tuned to that plant in that corner in this season. Gentle reminders arrive when a plant is actually due, not on a generic schedule.
- station 03
Snap a sad leaf when worry strikes
Yellow edges, brown spots, a droop that was not there yesterday. Fernfriend reads the symptoms, explains what is likely going on in plain words, and gives you recovery steps.

what it does
Small knowing, every day.
Knows your exact plant
Not just “a fern”. The species, how sure it is, and close look-alikes when a photo is ambiguous. You confirm before anything is saved.
Tuned to your window and season
A south sill in July and a north corner in January are different worlds. Each rhythm reads the light you actually have and shifts as the seasons turn.
Sick-leaf reading
Snap the worrying leaf. You get the likely issue, why we think so, honest confidence, and recovery steps in order.
Gentle reminders
A nudge when a plant is due, never a nag. Email or your own calendar, and a quiet “all good today” when nothing needs you.
Pet-toxicity flags
If a plant can hurt a cat or dog, you see it first, in plain words, with a check-with-your-vet note. No digging.
Model-agnostic
Readings route across vision models from more than one provider, and every answer is checked against a strict schema before you see it.
built ai-native
Without a model that can see, there is no Fernfriend.
This is not a watering calendar with a chatbot bolted on. Naming a real plant from a phone photo, reading the light in a specific corner, and recognizing an overwatered leaf were impossible for software a few years ago. Modern vision and language models are the whole product.
Fernfriend is model-agnostic. Each reading is routed across vision models from more than one provider, and every answer is validated against a strict schema before it reaches you.
How the AI works- 01
Identify the plant
A vision model looks at leaf shape, venation, variegation, and growth habit, and returns a species guess with an honest confidence.
- 02
Read your home's light
Your window direction, distance from the glass, climate, and today's season become a light reading for that exact spot.
- 03
Tune the rhythm
Water, feed, and repot timing are reasoned for that plant in that light, then shift with the seasons.
- 04
Read sick leaves
Yellowing, spotting, crisping, or pests become a likely cause, the clues behind it, and steps to recover.
Guidance, not a guarantee.
Every identification and every sick-leaf reading is a likely reading, shown with honest confidence, for you to act on sensibly. Plants are living things and photos can mislead. For a precious or valuable plant, confirm with a local nursery before you do anything drastic.
Pet-toxicity flags appear on every plant that needs one. If a pet has chewed something, call your vet; we are not a substitute.
Read our care and pet-safety stancefrom early-access gardeners
Plant people, a little less worried.
“My fiddle-leaf dropped three leaves the week I moved. Fernfriend said it was the move plus a dimmer window, told me to stop fussing with the watering, and to turn it toward the light. Two new leaves since.”
“I have two cats and had no idea my pothos was a problem. The pet flag was the first thing I saw. It lives on top of the bookshelf now, and the cats got the spider plant instead.”
