What firewood is this?

How it works

Upload one clear photo. The model looks for distinguishing features — bark texture, end grain pattern, ray flecks, growth-ring spacing, color and weight cues — and ranks the most likely species along with a confidence score and the reasoning behind it. You can tell it which side it's looking at, but you don't have to.

What makes a good photo?

• • End grain in focus is the gold standard — that's how an arborist would do it.
• • Bark shots work for many species when the texture is clear.
• • Whole log with both ends visible gives the model the most to work with.
• • Avoid blurry phone snaps of a far-away woodpile — those will get low-confidence answers.

Why we built this

CrackleKing is a firewood marketplace. The more people understand what wood they have (or want), the better the buyer-seller match goes. The tool is free, public, and unrelated to whether you buy or sell through us — though if it's helpful, the buttons above will get you connected to providers in your area.
