The professional drawing annotator for engineers and QA teams. Add balloon callouts to any engineering PDF, build dimension tables, and export quality inspection reports — all in your browser. No software to install.
Try BalloonifyIQ Free for 7 Days✓ No credit card required ✓ AI-powered OCR: 60 dimension reads included ✓ Full feature access
Hold X while clicking a dimension balloon and AI reads the exact text directly from your drawing — tolerance callouts, feature labels, and all — populating the dimension table automatically. No manual typing required.
Annotate multipage PDF drawings without splitting files first. Page tabs appear above the canvas — click to switch pages and all your balloons, dimensions, and notes stay organized together in one complete file.
Draw revision cloud outlines directly on your engineering drawings. Click to place points, double-click to close the shape. Right-click any cloud to toggle between the classic bumpy revision-cloud style and a clean dashed outline. Clouds export with your annotated PDF. Available on Trial, Pro, and Enterprise plans.
Enterprise plan now supports up to 5 seats under one account. The admin invites team members by email — each gets their own login while sharing a single 2,000 AI-read pool. Manage seats, track shared usage, and remove members any time from the account page.
Load a saved annotation file and BalloonifyIQ now tells you exactly which PDF to open — no more guessing which file goes with which session. The saved JSON stores the original PDF filename and prompts you to select it so everything lines up automatically.
Your standard tolerance settings now persist between sessions. Set your default tolerances once and they're there the next time you open the app — no more re-entering the same values for every new drawing.
BalloonifyIQ is a complete PDF annotation and drawing markup system for engineering and quality inspection. Load any engineering PDF, add numbered balloon callouts, build dimension tables, capture measurements with AI or manually, and export professional inspection documentation — all without leaving your browser.
From PDF to Production in Minutes
Professional documentation without the hassle.
Load any PDF drawing and start marking up immediately. Responsive interface that's easy to navigate. Rotate, zoom, and pan for precise work on any detail.
Add numbered balloon callouts in circles, squares, or diamonds. 9 color options. Fully customizable sizing and position — drag any balloon anywhere on the drawing. Numbers auto-increment as you place balloons, and can be edited or reordered at any time. Perfect for FAI reports and inspection documentation.
Work your way: Click to place balloons manually, or use AI-powered OCR to read dimension text automatically (Standard & Pro plans). Unlimited free OCR also available for basic dimension reading.
Press X to activate text extraction mode, then drag over any text on your drawing — dimensions, tolerance callouts, material specs, thread notes, surface finish, or general instructions. AI reads it directly from the PDF and drops it into your dimension table. No typing required. Available on Trial, Pro, and Enterprise plans.
Automatic tolerance calculations. Fully editable — click any cell to update values, edit or reassign balloon numbers, or delete rows. Min/max values calculated automatically. Feature types (Diameter, Radius, Angles). Export to CSV for Excel.
Add notes, instructions, or custom callouts directly on your drawings. Clarify details, label revisions, date your markup, or emphasize important information for manufacturing and inspection teams.
Generate ballooned PDFs for distribution. Export dimension tables as CSV. Save your work to resume later. Everything you need for production and documentation.
Your work saves directly to your computer's downloads folder. Keep sensitive drawings on-site. Full control over your data with no cloud dependency.
Searchable help center with quick start guides, troubleshooting tips, and best practices. Get answers fast with detailed documentation and step-by-step instructions for every feature.
Built-in page tab navigation lets you annotate all pages of a multipage PDF in a single file. Switch between pages with one click — balloons, dimensions, and notes stay organized by page. The legacy PDF Splitter is still available for splitting a PDF into individual files.
Draw revision cloud outlines on your drawings to flag change areas, highlight regions of concern, or mark up drawings for review cycles. Click to place points, double-click to close. Toggle between bumpy revision-cloud style and a clean dashed outline with a right-click. Clouds export with your annotated PDF. Available on Trial, Pro, and Enterprise plans.
Enterprise plan now supports up to 5 seats. Admins invite team members by email — each gets their own login while sharing a single pool of 2,000 AI reads per month. Manage your team, track usage, and remove seats from the account page at any time.
Create First Article Inspection (FAI) reports fast. Use the drawing annotator to balloon critical dimensions, auto-generate inspection tables, and export a complete quality inspection report as PDF or CSV.
Mark up engineering PDFs for manufacturers and machinists. Annotate drawings with balloon callouts, highlight critical features, add tolerance notes, and share a clean marked-up drawing PDF.
Quickly annotate PDF drawings for design review cycles. Use the drawing markup tool to add comments, flag dimensional requirements, and communicate changes clearly across your team.
Build complete manufacturing documentation packages. Annotate engineering drawings with numbered balloons, plan inspection sequences, and produce professional quality documentation ready for the shop floor.
BalloonifyIQ is a purpose-built PDF annotation tool for engineering and manufacturing teams. Unlike general-purpose drawing markup tools, it's designed specifically for engineering PDF drawing workflows — with numbered balloon callouts, automatic tolerance tables, AI-powered OCR for reading dimension values, and export formats built for inspection reports.
Whether you're a machinist reviewing a part drawing, a QA engineer running a First Article Inspection, or a manufacturer coordinating production documentation, BalloonifyIQ gives you a professional drawing annotator that works directly in your browser — no CAD software, no plugins, no installation required.
