The platform
One workspace. Every PDF workflow.
Most people use one app to edit a PDF, another to mark it up, a third to convert it, and a fourth to ask it a question. PDFDepth removes the handoffs. You open the document once, and everything you need is already in the window.
Open a document
Drag in a PDF or open one from your device. Nothing uploads just to view or edit it.
Do the work
Edit, annotate, measure, convert, sign, or ask the document a question — in the same place.
Share the result
Export, publish, or share a link and collect comments from your team.
36+ tools and intelligent workflows, all inside one workspace — not 36 separate websites.

Document intelligence
Your PDFs, understood.
AI in PDFDepth is not a separate tab you visit. It sits inside the document you already have open, so you can ask a question, pull a value, or compare a revision without breaking your flow.
Answers cite the page they came from, so you can verify the work in a click instead of taking it on trust.
Try it on your own documentAsk your PDF
Ask a question in plain English and get an answer with the page it came from.
Summarise
Condense a long document into the points, risks, and actions that matter.
Extract information
Pull structured values, references, and tables out of unstructured pages.
Compare documents
See exactly what changed between two versions of the same document.
Analyse drawings
Review technical drawings for missing dimensions and conflicting callouts.
Assist markup
Generate a first pass of annotations and callouts for you to review.
Technical documents
Precision when the document demands it
Drawings, plans, and specifications need more than a text editor. PDFDepthcarries a full technical toolset — calibrated measurement, takeoff, revision comparison, and CAD export — for the people whose documents are dimensioned.
Calibrated measurement
Set a sheet to its true scale, then measure distances, areas, and angles.
Quantity takeoff
Detect symbols, count fixtures, and export organised quantities.
Drawing comparison
Overlay revisions and catch every change between plan sets.
PDF to CAD
Extract clean vector geometry and export DXF or SVG for CAD and BIM.

Customers
Teams that live in documents
“The AI report generation alone saved our team 15+ hours per week. What used to be a Friday afternoon nightmare is now a 30-second click.”
“The AI Plan Review caught a structural issue we missed in three rounds of manual review. That single catch saved a $20,000 change order.”
“Chat with PDF changed everything. I can ask "show me all fire-rated assemblies" and get instant answers. No more scrolling through specs at 11 PM.”
“We evaluated six PDF editors. PDFDepth was the only one with AI takeoff tools. Our material takeoffs went from 4 hours to 15 minutes.”
Security
Your documents stay yours
Straight answers about how PDFDepth handles your files. We only claim what the product actually does.
Your PDF is not uploaded
Documents open locally in your browser, the same way a desktop application opens a file. Nothing is shipped to a server just to view or edit it.
Encrypted in transit and at rest
When you do choose to store or share a document, it is encrypted both in transit and at rest.
No third-party model training
We do not use your documents to train third-party AI models.
You control deletion
Remove a document from your workspace and it is deleted from storage. You decide what is kept.
We do not currently hold SOC 2, ISO 27001, or HIPAA certification, and we will not claim otherwise. If your organisation needs a security review, talk to us.

FAQ
Questions, answered
PDFDepth is a single workspace for working with PDFs. Instead of stitching together an editor, a converter, a markup tool, a measurement tool, and an AI assistant, you open a document once and every capability is already there.
Your PDFs deserve a better workspace.
