What is Roboflow Annotate?
Roboflow Annotate is a web app for labeling computer vision data with AI-assisted tools (Smart Select via SAM, Label Assist, Auto Label), plus dataset curation, augmentation, team workflows and annotation analytics.
Roboflow Annotate is a browser-based labeling workspace for computer vision datasets. It combines manual annotation tools with AI assistance so teams can move from raw images to a training-ready dataset inside one environment. The platform reports that 750,000+ datasets and 575+ million images have been labeled using Roboflow, which puts it among the more widely used labeling tools in the field. The core workflow is fast labeling with machine help. Smart Select builds polygon annotations in one click using Meta AI's Segment Anything (SAM) model. Label Assist applies custom trained models to a batch of images, and Roboflow claims this cuts human labeling time by 95%. Auto Label leans on foundation models to process thousands of images in minutes. All of it supports bounding boxes, instance segmentation, keypoints, whole-image classification, and multimodal data for vision-language model fine-tuning. After labeling, teams can augment images, search and filter the dataset, and read analytics that surface edge cases and weak spots. It is built for teams rather than solo clicking. Projects can be split across in-house labelers or outsourced annotators, with role-based access, assignment notifications, in-image comments for resolving labeling disputes, and a version history that lets anyone revert a change. Annotation Insights reports throughput and approval rates, which matters for anyone running a labeling operation at volume. The audience is developers, engineers, and technical founders who want to start on a free tier and read open docs, plus operations and AI leads who need managed support. Against plain open-source annotation tools, the draw is the AI assistance and the project management layer rather than the drawing canvas itself. Import and export formats are not enumerated on this page, so check the docs before assuming a specific pipeline works out of the box.
How do you use Roboflow Annotate?
1Create a Roboflow account and project
Sign up or log in at app.roboflow.com, then create a project and set the task type (detection, segmentation, keypoints, classification) that matches your data.
2Upload and organize images
Bring images into the project, then sort them into train, valid and test splits and apply augmentation settings where you need more variation.3Label with AI assistance
Use Smart Select for one-click polygons, or run Label Assist with a custom model or Auto Label with foundation models to pre-fill annotations, then correct anything the model got wrong.4Invite your team and assign work
Add teammates or outside labelers with admin, labeler or reviewer roles, assign batches to specific people, and rely on notifications when new work lands.5Review, comment and approve
Use comments to settle labeling questions, check the annotation history and revert versions if needed, then approve images so they move to the dataset stage.6Track progress and consult the docs
Watch Annotation Insights for images labeled and approval rate, and use the documentation for export formats and API details before handing data to training.
Pros and cons
Pros
- One-click polygon annotation through SAM-backed Smart Select speeds up segmentation workAI
- Label Assist and Auto Label can pre-annotate large image sets before human reviewAI
- Covers detection, segmentation, keypoints, classification and multimodal data in one toolAI
- Team features include role-based access, assignment notices, comment threads and version historyAI
- Dataset search, augmentation and analytics sit next to labeling, so curation does not need a second productAI
Cons
- Pricing tiers are not stated on the homepage, so budget planning requires a sales conversation or docs digAI
- Specific import and export format support is not listed on the page and must be verified before committingAI
- AI-assist output still needs human review, and the claimed time savings depend on how well custom models match your classesAI
- The product is tied to the Roboflow ecosystem, so teams standardized on other training stacks face export and workflow overheadAI
- Feature density is high, and new labelers will need onboarding before project setup and review flows feel naturalAI
