What MakeSense.ai is
MakeSense.ai is a browser-based tool for labeling photos and preparing datasets for computer vision projects. It supports point, line, rectangle, polygon, and label annotations. Listed model integrations include YOLOv5, SSD pretrained on COCO, and PoseNet; users can also load their own YOLOv5 models exported to TensorFlow.js format. Export options include CSV, YOLO, VOC XML, VGG JSON, and COCO JSON, while imports include YOLO, VOC XML, and COCO JSON. Which formats are available depends on the annotation type, and the format matrix marks some combinations as unsupported. The project says images are not sent to a server and that AI features run using TensorFlow.js. It works in a browser across operating systems, and documentation covers local and Docker setup; the Docker setup serves the application on localhost:3000. The project describes the tool as suitable for small computer vision deep-learning projects and dataset preparation. MakeSense.ai was founded in 2019, is licensed under GPL-3.0, and credits Piotr Skalski as author and copyright holder. The Free plan costs nothing.

The full review of MakeSense.ai
MakeSense.ai is an image-labeling tool for people preparing datasets for computer-vision projects. It is best suited to small projects that need familiar annotation types and model assistance at no cost. The browser-based workflow and local hosting options keep setup light, though the format matrix can constrain established pipelines.
Overview
MakeSense.ai focuses on labeling photos and preparing datasets, rather than a wider computer-vision workflow. It supports points, lines, rectangles, polygons, and labels, with model-assisted labeling from YOLOv5, SSD pretrained on COCO, and PoseNet. That range covers common annotation work for small projects, but unsupported format combinations may interrupt a workflow built around a specific annotation and file type.
The project says images stay on the user's device because they are not sent to a server, and its AI features run in TensorFlow.js. This browser-based approach suits users who want to avoid a complicated installation. Those who prefer to host the application themselves can use its local setup or Docker instructions; the Docker setup serves the app on localhost:3000.
Key features
Annotation and model assistance
The combination of manual annotation types and model-assisted labeling gives small teams several ways to prepare image datasets. Users can load their own YOLOv5 model if it is exported to TensorFlow.js format, a compatibility requirement to account for when choosing a custom model.
Dataset formats
MakeSense.ai imports YOLO, VOC XML, and COCO JSON, and exports CSV, YOLO, VOC XML, VGG JSON, and COCO JSON for supported annotation types. The breadth is useful when moving data between common formats, but support depends on the annotation and import/export combination. Check the matrix against the formats your project actually needs before committing to it.
Pricing
The Free plan costs nothing and includes browser-based photo labeling, model-assisted labeling, and dataset export to CSV, YOLO, VOC XML, VGG JSON, and COCO JSON. It is a straightforward fit for individuals and small projects that can work within the supported format combinations. No paid tier is needed for the listed labeling capabilities.
Platforms
MakeSense.ai supports web use and lists Linux, macOS, and Windows, as well as self-hosting. Its cross-platform browser approach avoids complicated installation, while documented local and Docker setups give users a self-hosted option. The project is licensed under GPL-3.0.
Who it's for
MakeSense.ai is aimed at small computer-vision deep-learning projects and dataset preparation. It fits people who want common image annotations, model assistance, and a free browser workflow, especially when keeping images off a server matters. Teams with fixed format requirements should confirm the matrix supports every step of their pipeline.
Pros and cons
- Pro: The free plan includes five annotation types, model-assisted labeling, and several import and export formats, making it practical for small dataset projects without a subscription.
- Pro: The project says images are not sent to a server, and AI runs in TensorFlow.js, which suits users who want browser-based labeling with images kept on their device.
- Pro: Local and Docker setup options serve users who want to host the application themselves.
- Con: Some annotation and format combinations are unsupported, which can make it a poor fit for pipelines with strict import or export needs.
- Con: Custom model loading is limited to YOLOv5 models exported in TensorFlow.js format.

Verdict
Choose MakeSense.ai for small computer-vision projects that need free image labeling, model assistance, and a browser or self-hosted workflow. Its privacy approach and range of common formats are compelling; the main reason to look elsewhere is a pipeline that depends on a format and annotation combination the tool does not support.
Getting started
- Open https://www.makesense.ai/ in a browser
- Use the browser version on Linux, macOS or Windows
- Choose an annotation type such as point, line, rectangle, polygon or label
- Load a listed model integration or a TensorFlow.js-exported YOLOv5 model
- Export the dataset in a supported format
- For local hosting, follow the documented local or Docker setup at localhost:3000
Limits worth knowing
The Free plan costs nothing. Some annotation and import/export combinations in the format matrix are not yet supported.
