Getting started

What Praxis is

Praxis is a runtime that watches aerial video and turns it into structure: tracked objects, zones that stay pinned to the ground, events you can count, and evidence you can audit.

Raw drone footage is a firehose. An operator watching a feed can hold maybe three or four things in their head at once, and the moment they look away, everything they knew about the scene is gone. Praxis sits between the feed and the operator and keeps that state for them.

The runtime ingests a video feed (plus telemetry when available), detects and tracks objects in it, evaluates spatial rules against them, and emits events with evidence attached. It runs in the cloud or fully on-site. It doesn't care which drone the feed came from.

Try the public software#

Three routes are available without an account. Each one includes its source and its claim boundary in the interface and in the software proof record.

Local

Select a video and run the preview model in that browser tab.

Memory

Inspect one manually prepared public event across three recordings.

World

Navigate a browser derivative of a published drone reconstruction.

The shape of the system#

Everything in Praxis reduces to one flow:

feed→objects→zones + rules→events→evidence

Each stage is documented on its own page. If you read nothing else, read Zones and Rules & events. They carry most of the ideas.

How Praxis works

The full pipeline from raw frames to an event with evidence, in seven steps.

Zones

Watch areas anchored to the world, not the screen. The camera moves, the zone doesn't.

Events API

Query zone events as JSON. There's a live sample feed on the page you can run right now.

The challenge

Count cars entering a zone by hand, then see what Praxis counted on the same feed.

The broader Praxis runtime is in private beta, and the hosted API is not publicly available. Local, Memory, World, the challenge, and their source records are public software examples.
