Find the part that failed
A bulging capacitor or a burnt resistor: know what it is and look up a replacement before you desolder anything.

Which board are we looking at today?
Drop photos of a board here
Front and back of the same board go into one project.
Pick up where you left off
Point your phone at a circuit board. Know the parts on it.
CircuitLens finds the components in the photo, reads their markings and draws how the parts connect. On your phone or your computer, in six languages.

From a photo to a schematic
Look around without an account: every tool and a sample analysis are open to everyone. Sign in to analyze your own boards and keep them.
Take a photo
Lay the board flat, fill the frame and avoid flash glare, so the markings stay readable.
Every part, named
Each part gets its type, its marking, a likely part number and its package.
The schematic, drawn
An approximate schematic of how the parts connect, which you can export to KiCad. Then ask questions about the board in plain words.
Made for the bench and the classroom
Repair technicians, students and makers use it for different reasons.
Understand the board in front of you
Pinouts, reference sheets and short quizzes for the parts you find, so the next board is easier.
Free tools, no account needed
In the same six languages, every one of them free and open without an account.
Start free, pay when you analyze more
Plans change how many boards the AI analyzes each month. Every tool stays free.
Free 1 analysis every week, and every tool.
Analyze a board
One photo is enough: the AI names every part, draws the schematic and answers your questions about the board.
New analysis
Add one or more photos of the same board: front, back, a close-up.
The AI does
- Names the visible parts and says what they do
- Draws the schematic and the parts list
- Answers your questions about this board
It does not
- See the hidden side of the board
- Read a worn-off marking: it tells you so
- Measure: check the key values
From this computer
Drop a photo here, or pick it from a folder. Best when the photo is already on the computer.
With my phone
Sharper and straighter: the phone guides the tilt and the crop. Scan the code with its camera, no sign-in on the phone.

Ask about this board
For example: "What does this board do?" or "Why is there a capacitor right next to the USB-C input?"
