Drawings · maps · scans
APOS reads your PDFs, scans and photos, including handwriting and seven non-Latin writing systems. It works out what kind of document it is and turns every label into something you can search, filter and fly to in 2D or 3D.

01 — What it does
Upload a document and APOS does the reading, sorting and indexing. You get straight to the label, room, valve or station you were looking for.
Two readers work together. A fast text engine handles printed labels, and a vision reader takes over for handwriting, non-Latin scripts and faded scans, so a 1930s survey map gets read as well as a fresh PDF.
Detects the document type and sorts every label into stations, valves, rooms, dimensions, tags and more.
Pick one kind of label and the rest of the drawing dims, in 2D and in 3D.
Keyword and meaning-based search with suggestions. Every hit pans the view straight to it.
Fly over the drawing as terrain, with labels as beacons. Select one and the 2D view follows.
Split, overlay and flip between versions, and see which text changed.
02 — Accuracy
Every release is tested on 48 public-domain drawings, maps and scans, from a 1909 hand-lettered pier drawing to a Guangzhou metro plan and a stained Soviet wiring diagram.
Share of expected labels read exactly. Figures in brackets also count small spelling or punctuation differences. Results on your documents depend on scan quality.
03 — How it works
Drop in PDFs, SVGs or images, or paste from the clipboard.
Every label is read and placed exactly where it sits on the page.
The document type is detected and labels are grouped by kind.
Search, filter and fly the drawing in 2D or 3D.
04 — Platform
Huge sheets stream in tiles, so only what you see is loaded. The index keeps every label one keystroke away.
05 — Pricing
Every plan includes the full 2D and 3D workspace, text recognition, search, filters and AI assistance. Plans differ in cloud storage and monthly processing. Prices in USD; annual billing (2 months free) is available in the app.
