AI ballooning
Upload PDF / PNG / JPG drawings: a YOLO vision model reads the whole sheet and frames every dimension annotation (no manual region selection), balloons are numbered, DeepSeek’s vision model turns dimension text into OCR values, and inspection sheets (Excel), ballooned PDFs and reports export in one run.

Core features
Generates balloons
Auto-groups and numbers balloons per view with sequential numbering; balloons and leaders avoid dimension lines so annotations stay clear.
DeepSeek OCR
Turns dimension text into OCR values with the DeepSeek vision model.
Exports sheets & balloons
Excel inspection sheet, ballooned PDF and report in one run.
Deliverables
One drawing in, three files you can actually hand over
The result is not a pile of coordinates. An inspector can work from the ballooned drawing, a planner can edit the Excel sheet and a customer can sign the report.
Ballooned PDF
InspectionEvery dimension is numbered and connected to its feature, ready to print as the inspector’s reference sheet.
Excel detail sheet
DataIndex, inspection item, feature description, nominal, tolerance and measured value — editable and easy to merge into your systems.
Inspection report
DeliveryGenerate a report with custom templates and field mapping, keep revisions, and deliver it internally or to the customer.

Workflow
Five steps per drawing, no tool switching
Reading drawings, copying tables, numbering balloons and formatting reports collapse into a single desktop workspace.
- 01
Import
PDF / PNG / JPG, multi-page and batch import with page management.
- 02
Detect
A YOLO vision model frames every dimension annotation on the whole sheet (no region selection); switch CPU or GPU inference. Detection usually takes about one second per drawing.
- 03
Review OCR
Values are extracted and reviewed; cloud OCR uses the DeepSeek vision model.
- 04
Balloon
Balloons are grouped and numbered per view with sequential numbering; balloons and leaders avoid dimension lines.
- 05
Export
Produce the ballooned PDF, Excel sheet and inspection report as one package.
Capabilities
Covers single-drawing review and full-batch delivery
Beyond detection: batching, templates, version comparison and model training live in the same workstation.
Batch the whole set
Detect, review, balloon and export across files and pages with one run.
Review every value
Confirm or correct each dimension before it enters the deliverable.
Compare drawing revisions
Compare dimensions and tolerances between revisions and see every change.
Training loop
Turn corrected results into samples and improve models for your drawing types.
Model market
Switch ONNX models per drawing type instead of training from scratch.
Built for the shop floor
A Windows workstation fits engineering and inspection desks.
Batch
Export a whole set, not one drawing at a time
Batch jobs run across files and pages with unified detection, review, numbering and export. Batch balloon printing lets you choose pages, scale and overlays.
- Mixed multi-page PDF and images
- Batch detect / number / print
- Resumable jobs, results saved per page
Revisions
Stop hunting for changes by eye
Load the old and new drawing and run the comparison. Added, removed and changed dimensions are listed with status, match confidence and tolerance differences, and each row locates the annotation on the drawing.
- Synchronised side-by-side zoom
- Change list with status and confidence
- Export the change list for review
Scenarios
Built for high-frequency drawing review
The more drawings arrive and the tighter the deadline, the more manual numbering and copying costs.
Volume spikes
When drawings arrive in batches, one batch run handles detection and numbering.
- Batch import
- Consistent numbering
First article & sampling
Full-dimension balloons for first article, stable numbering for sampling records.
- Full-dimension balloons
- Measured values
Incoming inspection
Normalise drawings from different suppliers into one detection and reporting standard.
- Format compatibility
- Consistent reports
Drawing revisions
When a customer revises a drawing, locate dimension and tolerance changes fast.
- Revision diff
- Exportable change list
Data boundary
Where your drawings are processed, stated plainly
Preview, detection and export run locally in the Windows client. Features that use cloud OCR are labelled and metered.
Read the data & security pageLocal first
Detection and export run on your workstation; drawings do not have to be uploaded.
Cloud OCR is explicit
Cloud OCR runs on the DeepSeek vision model; when selected it is metered per run and usage is visible.
Deliverables stay on your machine
Ballooned drawings, Excel sheets and reports are written to the folder you choose; retention is up to you.
Pricing
Validate with the free quota, then decide
The free quota is enough for one complete delivery run. When it fits, we recommend the annual plan — ¥490 equals ten months of monthly billing.
We recommend the annual plan: ¥490/year equals ten months of monthly billing; final price and activation are confirmed with our team.
Run one of your own drawings through the full workflow
No environment setup required. Install, import a drawing, detect and export — see the ballooned PDF and report within ten minutes.
