AI progress tracking
Point a camera at it. That's the count.
Nobody counts placed pieces. It is tedious at 300 and absurd at 2000. So progress tracking has always meant guessing, until you hand the guessing to something that is good at it. Snap a photo and AI estimates how many pieces you've placed, every session, consistently.
Under the hood
An estimate with its homework attached.
Each photo goes to a vision model that reads the state of the table: the assembled area, the density of connected sections, the loose pieces waiting at the edges. It comes back with a number, and it also comes back with reasoning and a confidence level, so an estimate never feels like a black box. You can see why it thinks you're 40 percent in.
Prefer to be exact? Type your own count for any session. The AI is there to remove the chore, not to argue with you.
Why it matters
Consistent guesses make real stats.
One estimate is a curiosity. A photo every session is a dataset: your pace per sitting, your best session, how much is left and roughly how many evenings that is. The estimates feed a puzzle journal that builds itself while you do the fun part.
Common questions
Questions about the AI.
How does AI estimate puzzle progress from a photo?
You upload a photo of the puzzle mid-build, and a vision model (Anthropic's Claude) looks at it the way a person would: how much of the image area is assembled, how dense the connected sections are, what is still loose around the edges. It returns an estimated piece count along with its reasoning and a confidence level, so you can see how it got there.
How accurate is the estimate?
Think friendly guess, not census. On a clear, well-lit photo it usually lands within a reasonable range of the true count, and the app shows a confidence level with every estimate. For watching progress build across sessions, a consistent good guess is all you need. If you prefer, you can always type an exact count instead.
Do I need special photos?
No. A regular phone photo from above works best: decent light, most of the puzzle in frame. No tripods, no scanning apps, no grid overlays.
What happens to my photos?
They are stored privately with your account and sent to Anthropic only to produce the estimate. Anthropic does not use API data to train its models by default, and we never post or share your photos. The details are on our privacy page.
