AI SegmentationStop digitizing by hand. Detect every object in QGIS automatically.
Outline a single object, the AI finds all the others in your image.
No manual tracing, no lost days.
Why automate
Point by point takes forever
The old way
By hand, point by point. About 30 seconds per building, five in a full minute.
Source: Kirillov et al., Segment Anything (Meta AI, 2023). Fully manual annotation averaged 34 s per mask.
The new way
Automatic with AI. Hundreds of buildings in under a minute. Draw the zone, the AI detects them all.
What it does
Segment any object, at any scale.
Outline any object
Detect every match at scale
Refine and export
Built-in library
Detect anything in your imagery
If it is visible in your raster, the AI can outline it.
Building footprints
Every rooftop, extracted as polygons.
Solar panels
PV arrays and solar farms.
Trees
Canopy, parks, hedges.
Roads & paved surfaces
Networks and surfaces.
Swimming pools
Residential and public pools.
Field parcels
Agricultural boundaries.

1 tile = one image square of about 400 m per side, analyzed in a single AI pass regardless of how many objects it contains. 300 tiles ≈ 50 km² to try, 10,000 / month ≈ 1,500 km².

Frequently Asked Questions
- AI Segmentation is a free AI-assisted segmentation tool for QGIS: point at what you want to extract and get precise outlines instantly.
- Yes. AI Segmentation is built on Meta's Segment Anything Model (SAM) family. Manual mode runs SAM 2 locally on your machine, no internet needed. Automatic Pro runs SAM3 in the cloud to detect every object in your zone at once.
- AI Segmentation Pro is an upcoming professional version with fully automated extraction. Instead of clicking object by object, you describe what you want to extract and the AI does it across your entire dataset automatically.
- Yes. AI Segmentation comes with an unlimited free plan, open source.
- The interactive click-to-segment mode does not require an internet connection: nothing is uploaded. The automatic detection mode (the free trial and AI Segmentation Pro) sends the image tiles you detect to our secure EU infrastructure for higher precision and full automation; those tiles and the resulting masks are stored for the lifetime of your account so you get detection history and support, and you can request deletion at any time.
- You do. Every polygon you extract is yours to keep, use commercially, and redistribute. Your imagery stays yours, and we never resell or reuse your imagery or your results.
- Yes. You can cancel anytime from your dashboard and keep Pro until the end of the period you already paid, with no lock-in. Because Pro gives immediate access to the service, subscription fees are generally non-refundable, but if something went wrong just email us and we'll make it right.
- Anything visible in your images: buildings, roads, vegetation, vehicles, water bodies, agricultural parcels, and more. It works on satellite imagery, aerial photos, drone images, and any other image layer in QGIS.
- Yes, a free account: sign in with your email or a Google or Microsoft login, no credit card needed. It takes under a minute.
- It works with any RGB image in QGIS: local files (TIFF, JPG, PNG) and online map layers like Google Satellite or OpenStreetMap. Extra bands like NIR or hyperspectral are not used yet.
- Yes, there is no hard size limit. Automatic mode splits a large zone into tiles, detects each one, and stitches everything back into a single seamless polygon layer, merging objects that cross tile edges. A larger area simply uses more tiles (about 1,500 km² per month on Pro).
- Anywhere you have imagery. It runs on whatever raster you load, your own aerial or satellite imagery or online basemaps like Google Satellite, so it is not limited to any country or provider. Detection quality depends on image resolution, not location.
- When you are done, click Export or press Enter. All your outlines are saved as a standard GIS file directly in QGIS, ready to edit, style, or export to any format.
- AI Segmentation runs interactively inside QGIS, where you draw a zone and detect. Power users can drive it programmatically through the QGIS AI Agent for scripted, repeatable runs. A dedicated batch API is not available yet.
- Open QGIS, go to Plugins → Manage and Install Plugins, search for "AI Segmentation" and click Install. Or download directly from the QGIS Plugin Repository.
- QGIS 3.22 or later, on Windows, macOS, or Linux. No GPU required. On first launch the plugin installs its AI dependencies automatically (a few hundred MB, one time).
- No, it is a QGIS plugin. QGIS is free, so you can install it alongside ArcGIS and export your segmentation results as standard vector files (GeoPackage, Shapefile) to use anywhere.
- No programming or AI knowledge required. If you can click on a map in QGIS, you can use this plugin. It is designed for surveyors, urban planners, ecologists, researchers, and anyone who works with aerial or drone imagery.
- Corporate proxies that inspect secure connections used to block the dependency install. Since version 1.2.2 the plugin detects this and switches to a compatible connection automatically, so update to the latest version first. If it still fails, send us the error report from the plugin and we will help.
- Update the plugin: in QGIS, go to Plugins, then Manage and Install Plugins, then Upgrade. Most reported issues, including dependency install failures, are fixed within days. If it persists, the error dialog has a report button that sends us the details directly.
