iOS public beta · live now

Get to know
every plant
you meet.

Point your camera at anything green, on your shelf, in the garden, or out on the trail, and Vivary names it right there on your phone. When it's sure, it says so. When it isn't, it says that too, and Ken, your resident naturalist, helps guide you to the right species.

The Vivary beta is live. Sign up and we'll send your invite, along with one thing we'd love you to test.

the botanist model

Placed as deep as the
evidence allows.

Most plant ID apps act like oracles. They give you one species name and one number, and when the photo is unclear they make something up. A botanist won't. Vivary works that way too, across three tiers.

tier 01

On-device identification,
family-first.

A small model that runs entirely on your phone, trained to see the way a botanist does. It reads family, genus, and species at once, and gives you the most specific level it actually trusts. When it can't reach the species, it hands you the genus or the family instead of throwing up “unknown.”

family→genus→species
Keying to family…Narrowing to genus…Down to species, if it's sure…

tier 02

Guided capture,
the right close-up.

Sometimes the detail that decides it isn't in your photo. Vivary asks for the one shot that would settle it, a leaf up close, a flower, the underside of a fern, and reads that frame instead of guessing from the first.

34%low confidence→94%high confidence
Guided capture takes a low-confidence ID to high confidence with the right photo.
on-device · asks, never guesses
tier 03
K

Our own broad model first.
Ken reasons second.

When your phone's catalog runs out, the photo goes to a second Vivary model, covering most of what you can photograph in the United States, with a world tier of nearly 69,000 species behind it. It answers first. Only when it's not confident on a species does Ken, the Botanist VLM, reason it further.

cloud · our model names, the VLM reasons
“

The families our model can't place from a casual photo are, almost one for one, the same families a trained botanist can't place either, for the same reasons. When your identifier fails the way an expert fails, you're modeling the problem, not fighting it.

guided capture · tier two

When Vivary isn't sure, it asks.

A first guess is a starting point, not the answer. When two look-alikes come down to one detail your photo missed, Vivary asks for that shot and reads it again. It's what a botanist does when they ask to see a single clean leaf.

62%56%→92%
Monstera deliciosa, from a variegated plant on a shelf: a best guess it wouldn't commit to, with heartleaf philodendron still in the running. One whole-leaf close-up later it's identified at 92%. The deciding detail was there all along; it just needed the right frame, and a system willing to ask for it instead of guessing.
field marks · what vivary read

Grounded in what's
actually visible.

Every ID comes with the characters behind it, the same things a botanist would look at. Here's what Vivary read off the monstera, on the phone, and the one the close-up nailed down.

fenestration
splits confirmed by capture
Deep cuts running in from the edge, the mark of a mature Monstera. The whole-leaf close-up is what made it readable.
margin
lobed
The edge is cut into rounded lobes rather than running smooth.
division
pinnate compound
Read as leaflets along a central rib. A deeply split leaf looks that way to the model, and it reports what it sees.
apex
acuminate drip tip
The tip draws out to a fine point that sheds water.
plant habit
upright herb
Soft-stemmed and standing, not woody.
arrangement
alternate
Leaves attach one at a time, staggered along the stem.
what's inside

A field guide that lives
in your pocket.

Name a plant, keep it, and look after it over time. Everything is laid out like a real field-guide entry, and where the data runs out, Vivary says so instead of filling the gap.

01 · identify

Point, capture, know, without ever uploading a thing.

It all happens on your device. You get the species, its common name, and the next-best matches, each with the confidence behind it, in plain words.

02 · private

On-device by default.

No account to recognize a fern. Identifying, keeping, and caring for your plants happens on the phone, and nothing leaves it unless you start one of the few features that need the cloud. Those say so before they go, and what you send isn't kept.

offlineno account
03 · care

Care that fits the plant you actually have.

Light, water, humidity, and a nudge when the next watering is due, laid out as field-guide rows. Where there's no reliable number, it says “no data available” rather than inventing one.

04 · health

Spot trouble early.

A health check sends the photo to Ken, who looks over the leaves for pests, stress, and overwatering, then points you toward a fix. He won't hand you a diagnosis he can't stand behind.

cloud · Ken
05 · keep

Shelf · Garden · Wild.

A running record of everything you grow, watched over time across three places. It's the vivary the app takes its name from.

meet ken

The honest
naturalist.

Ken lives in the Ask tab, and he's warm, precise, and knowledgeable. His name comes from ken, the range of what a person can know. He tells you what he's sure of, flags what he isn't, and never passes a guess off as a fact.

Honest about the cloud.

Identifying a plant, curating your collection, and caring for them happens on your phone without an account. A few features actually need more than the phone, like chatting with Ken, health checks, and the broad tier, our cloud model with the Botanist VLM behind it, and those run in the cloud. We tell you exactly when that line gets crossed, and nothing leaves your phone unless you start it.

Not a mockup.

These are real screens from the current TestFlight build: an on-device ID, the Wild field journal, the weather-aware calendar, and a shared-care garden bed. Every confidence word and field mark is what testers actually see.

who's building this

One developer.
One honest app.

I'm Dallas, the founder and sole developer of Vivary. As a gardener myself, I wasn't satisfied with the “false confidence” that other plant identification products offer, or their lack of features to help manage my plants the way I enjoy caring for them. From how I organize my house plants to how I work in the garden, I've built each feature with a personal touch, so I'd have the app I've always wanted: an honest plant identification app that works anywhere you might be experiencing the joy of interacting with plants.
