A virtual soil sensor
Skip the 50 euro Bluetooth probe in every pot. The moisture you see is a physical water balance, updated every morning, for free.
No sensors to buy. No guessing.
Water your plants when they need it, not when the calendar says.
FloraSense is a virtual soil sensor and AI botanist. It models every pot against your local weather, moves watering as the sun, rain and heating change, warns you before frost, and looks at a leaf photo when something is wrong.
- Zero hardware
- Every number re-checked
- Pay only for finished plans
From a photo to a calm morning briefing
Houseplants die of the calendar. Overwatering in a dull, humid week and underwatering in a dry, heated one are the two ways to lose a plant.
- 1
Tell us where it grows
Pick your city, then add a plant by photo or from the list. Say whether it stands by a south window, on a covered balcony or in the garden.
- 2
We model every pot
Each day we read evaporation, rain, sunshine and frost for your exact spot and take the water out of the pot, in millilitres, plant by plant.

You get what to do today
"Water the calathea with 250 ml. Postpone the monstera, it still holds 38%. Frost tonight: bring the olive in." Only when something needs you.
Care that follows the weather
Four things a fixed schedule cannot do.
A self-adjusting calendar
Three overcast days in a row? Watering slides forward and you are told why. A heatwave? It comes sooner. Overwatering is the number one killer, and this prevents it.
Frost, heat and wind alerts
An evening warning before a hard frost, a UV spike or a dry gust, for balcony and garden plants, with the time it hits and what to do.
A plant doctor in your pocket
Photograph a yellowing leaf and get likely causes, weighed against this plant’s own weather and watering over the last two weeks.
Plant doctor
Is it too wet, too hot, or something else?
Yellow lower leaves look the same whether the pot is drowning or starving. FloraSense knows which of the two it has been: it reads the photo together with the weather and the watering log and says what is most likely, what it saw as evidence, and what to do first.
- Identify a plant from one photo, with its confidence
- Findings with the visible evidence behind each
- Treatment as a checklist, gentlest step first
- Honest about what a photo cannot show

Verified, not guessed
The AI writes the words. The numbers come from physics.
Millilitres, moisture and dates come from an open water-balance model, and are then re-derived independently before you see them. The botanist that writes the advice is not allowed to compute or invent a figure; if it tries, that note is replaced. Every plan shows the checks it passed.

Questions
Do I need a soil sensor?
No. FloraSense estimates moisture from your plant, pot, soil, where it stands and the weather. You tell it when you water, and it follows the pot from there. The more accurately you log, the closer it tracks.
How accurate is it?
It is a model, not a probe, so treat it as a very good reminder rather than a lab reading. It starts from the day you last watered and corrects itself every time you log a watering. The numbers are shown openly (leaf area, pot capacity, thirst factor) so you can see why.
Where does the weather come from?
Open-Meteo, a free open weather service, for the exact location of each garden: evaporation, rain, sunshine, UV, wind and soil temperature.
What if I garden in several places?
Add each place as its own garden, a home, a balcony, a client site, each with its own weather and morning plan.
Is the plant doctor a real diagnosis?
No. It is advice from an AI looking at one photo, with the weather and watering history as context. It tells you how sure it is and what would confirm it. For a plant that keeps declining, ask a nursery.
Does it store my photos?
A small thumbnail is kept with each photo check so you can look back. Photos are sent for analysis only and are not used to train models.
