Sketch Import · Early access
Draw it on paper. Get a validated single-line diagram.
Photograph the one-line you sketched on site. Sketch Import reads it, matches your scribbled equipment against 22,000+ real models, sizes every wire with the deterministic engine, and runs 45 automated NEC checks, in minutes. If your sketch has a design error, you find out now, not at plan review.
Built into the same designer that produces permit-ready plan sets
How it works
From photo to permit-ready design, step by step.
1
Upload any sketch
A photo of a napkin or whiteboard, a scanned PDF, or a screenshot from another design tool. If it shows a single-line diagram, it works as input.
2
The sketch gets read, symbol by symbol
Vision AI finds every component, connection, rating, and label on your drawing, and marks exactly what it could not read instead of guessing. You watch it happen: detection boxes appear on your sketch as each piece is found.
3
The engineering is done by the engine, not the AI
Handwritten labels like "7.6kW SolarEdge" are matched against a database of 22,000+ real equipment models. Wire sizes, conduit fill, and breaker ratings are calculated by the same deterministic engine that powers every design in the app. Then 45 automated NEC checks run against the result.
4
Review what was built, corrected, and caught
The Sketch Review report shows what was recreated, which models were matched, what the check engine corrected, any design errors it caught in your sketch with the NEC citation, and every assumption it made, each one a single tap to change.
Other tools trace your sketch. This one engineers it.
The AI only reads the drawing. Every calculation, correction, and caught error comes from the deterministic NEC check engine, the same one that validates every design in the app.
It catches design errors in your sketch.
A missing grounding electrode, an undersized breaker, a 120% rule violation. Every finding comes from the NEC check engine with a code citation, the same 45 checks that vet designs drawn by hand in the app. Drawing tools trace your sketch. This one engineers it.
It never guesses on your ratings.
Wire callouts on your sketch are read and compared, never blindly copied. If the engine calculates #6 where your sketch says #8, you see the correction with the citation. If a scribble is unreadable, you get asked, with a zoomed crop of that exact spot on your drawing.
Real equipment, not generic symbols.
Every inverter, battery, and disconnect resolves to an actual manufacturer model with its real specs, ready for stringing, load calcs, and a permit-ready plan set. Not a box with a label. A design you can submit.
One undo reverses the whole import.
The entire reconstruction lands as a single operation in your design history. Press undo once and the canvas is exactly as it was. This is a real editor operation, not a one-way import.
If it shows a one-line, it works as input.
Hand-drawn sketches

A scanned or exported single-line page from an existing plan set.
Screenshots from other tools
Rebuilt as an editable, validated design you actually own.
Questions installers ask
- What kinds of sketches can it read?
- Single-line diagrams of solar and storage systems: hand-drawn sketches, whiteboard photos, scanned PDFs, and screenshots exported from other design tools. It is built for electrical one-lines, not roof plans or site photos.
- How accurate is it?
- The honest answer: it tells you. Anything it could not read with confidence is flagged or asked about with a zoomed crop of your drawing, instead of being silently guessed. Every reconstructed design then runs through 45 automated NEC checks before you see it.
- Does it copy the wire sizes from my sketch?
- No. Wire sizes, conduit fill, and breaker coordination are calculated by the deterministic sizing engine, the same one used for every design in the app. Your sketch callouts are read and compared, and any conflict is reported with the code citation so you can see what changed and why.
- What if it cannot identify a piece of equipment?
- Unreadable model text falls back to a ranked suggestion from the equipment database, marked as an assumption you can change in one tap. Symbols it cannot classify are preserved as placeholder devices so your topology and wiring survive, flagged for your review.
- What happens to my uploaded sketch?
- It stays private to your organization and is stored with the project so you can compare the sketch and the finished design side by side. Delete the project and the sketch goes with it. Sketches are only used to improve the product if you explicitly opt in.
- Do I need CAD experience to use the result?
- No. The reconstruction is a normal design in the app: every component is editable, the design checks keep running as you work, and the same project can go straight to a permit-ready plan set.
