Built by working arborists, for the person who walks past the tree every day and has no way to say what they’re looking at.
The tree that gets removed is usually the one nobody looked at for three years. By the time a thinning crown is obvious from the driveway, the choices have narrowed to a bucket truck and a stump grinder. Caught two seasons earlier, a lot of those trees are still standing.
What’s missing in that gap isn’t expertise. It’s attention. An arborist sees a property once; the person who lives there walks past that tree every day and notices things constantly — with no way to turn any of it into a name, a timeline, or a reason to act.
CanopyKeep closes that gap. Point a phone at what you noticed and get a real answer back, early enough that keeping the tree is still on the table.
Type a symptom into a search box and you get ten pages about “common tree diseases.” None of them are looking at your tree. CanopyKeep is: photograph the spotted leaf, the split bark, the beetle under the mulch, and it comes back with a named condition, how urgent it is, and what to do this week.
Three tools, one page. Diagnose reads a symptom. ID names a species from three photos — the whole tree, the bark, a branch. Age turns a tape measure around the trunk into a year and a growth curve. Alex, the arborist voice built into every result, takes the follow-up questions.
It’s free because the hard part was already paid for. CanopyKeep is the homeowner half of ArbKeep, plant health care software for working arborists — the same diagnostic bench, pointed at the person standing in the yard rather than the one billing for the visit.
I’m an orchardist. Most of what I know about trees came from spending years with the same ones — the walk at the end of the day, looking for what changed since yesterday. Nothing about that is clever. It’s just time, paid in attention, and it is what catches a problem while it is still small.
Technology is how that walk reaches more trees than one pair of hands ever will. It doesn’t replace the looking; it hands the looking to everyone who owns four trees instead of four hundred. And it keeps getting better at it — year over year the tools close in on what every stakeholder of a tree actually needs, the homeowner and the arborist and the tree itself.
That’s the whole bet. Save more trees than we take down.
Every number on the screen comes from somewhere. Here is all of it.
Most of what kills a mature tree happens underground — girdling roots, a trunk buried too deep, compaction from equipment that came through years ago. No camera reaches it. So CanopyKeep works inside what a photo genuinely supports: leaf spots, cankers, rusts, borers, scorch, most insect damage, and the species itself.
And it says out loud when the answer is on the other side of that line. That sentence is the most valuable thing here — it arrives while the tree is still savable, and getting the right person to it is the difference between a treatment and a removal.
Usually roots, water, or both — and usually slower than it looks. Scratch a thin twig: green under the bark means it is still alive.
Brown edges on otherwise green leaves is drought or heat. Spots that spread, or leaves dropping while still green, is more likely fungal or insect.
Most leaf spots are fungal, cosmetic, and outgrown by next season. The ones worth acting on keep spreading into new growth or arrive alongside dieback at the branch tips.
Early leaf drop is a stress response, not a disease by itself. If it starts at the top or on one side, look at the trunk and the roots before the leaves.
Scratch a pencil-thick twig with a thumbnail. Green and damp underneath is alive; brown and dry the whole way round, on several twigs, is not.
Leaf spots, cankers, rusts and most insect damage, yes. Roots are behind a lot of decline and a photo cannot see them, so the answer says which part it is sure about.
Three photos beat one: the whole tree, the bark up close, and a branch. Leaf shape alone is ambiguous; leaf plus bark plus branching usually is not.
Start with how they attach to the twig — in opposite pairs, or alternating — because that one detail rules out most of the list. Shape, edge and veining come after.
Sometimes. Shagbark hickory is unmistakable; most young bark is not. Send it anyway — the answer tells you how sure it is.
Genus nearly always, species most of the time. Cultivars and hybrids are the hard cases, and it says so instead of guessing.
Measure around the trunk at 4½ feet up, divide by π for the diameter, and run that through growth curves for the species. No coring, no counting rings.
Run a tape around the trunk at 4½ feet above the ground and divide by 3.14. Measure at the base instead and the root flare inflates every number that follows.
Depends on the species and on where it stands. The same red oak puts on twice the trunk in Georgia that it does in Minnesota — which is why this asks where the tree is first.
The estimate projects trunk, height and spread out to 20 years for your species and climate region. Read it as a range drawn from measured street trees, not a promise.
Most multiply diameter by a single growth factor for the species and stop there. This runs the USDA Urban Tree Database — measured street and park trees, the data behind i‑Tree.
Roughly one tree in four falls outside the tables, and the tab says so rather than estimating anyway. Ask Alex instead — a conversation can work from a species the tables cannot.
Yes, and there is no sign-up. Diagnosis, identification, age estimates and three follow-up questions all cost nothing.
Age estimates need it, because growth curves are calibrated per climate region and a region-less estimate is a confident number about a different tree. Naming a state is enough; you never have to share GPS.
They go to an AI model for the read and stay with the case so it can be reopened later. What is kept and for how long is in the privacy policy.

No. It is a first read — enough to tell a cosmetic problem from a reason to call someone, and it says plainly which one you have.
