Choosing well
Which platforms does it need to run on?
Start with the platform you plan to use. The chart compares web, API, self-hosted, macOS, Windows, and Linux availability; it does not establish Android app support.
If you want to annotate from a Xiaomi, Redmi, or POCO phone or tablet, confirm Android availability and check whether the needed labeling tasks work there.
Which annotation types and image formats do I need?
Choose a tool that supports the kinds of labels you need and the image formats in your dataset. These are comparison points in the chart, so check the individual tool's details before deciding.
Do I need model-assisted labeling or an API?
Look for model-assisted labeling if it is part of your workflow, and check API access if you need to connect the tool to other software. API availability is not the same as having an Android app.
How will I export and share the dataset?
Check dataset export options against the format your next step requires. If other people will work on the project, compare the available team collaboration features as well.
Can I use it on a free plan?
Compare free-plan terms with the features and usage you need. A free trial and a free plan are different pricing options; check the listed terms and any paid starting price.
If you need to read or change the code, check the tool's licence rather than assuming that free access means open source.
Questions people ask
Is there image annotation software for Android?
The chart does not specify Android app availability. Check the tool's platform details, especially if you plan to annotate on a Xiaomi, Redmi, or POCO phone or tablet.
What should I compare when choosing image annotation software?
Compare annotation types, image formats, model-assisted labeling, dataset export, team collaboration, API access, platforms, and pricing.
Can I annotate images for free?
The chart includes tools with free plans. Check the individual plan terms to see whether they cover your labeling needs.
What is the difference between a free plan and a free trial?
A free plan is an ongoing pricing option; a free trial provides access for a limited period. Check the terms for the specific tool.
Does image annotation software work offline?
The chart compares web and self-hosted availability, but does not state whether a tool works offline. Check its own platform and connection requirements.
Is free image annotation software open source?
Free access does not by itself mean a tool is open source. Check its licence if you need to inspect or change the code.
