Evaluating Voxel51 alternatives? Leading AI teams focus on: native multimodal data support (image, video, 3D, LiDAR), consolidated annotation and curation workflows, and enterprise-grade infrastructure that delivers measurable ROI.
Consolidated platform for your entire data pipeline
Encord enables teams to consolidate data curation, annotation, and model evaluation workflows into one secure platform. Eliminate the need to build fragmented data management infrastructure or integrate multiple point solutions. Reduce engineering overhead costs and accelerate time to market to gain competitive advantage.
Advanced visual data annotation and curation
Explore and organize datasets with features such as embedding plots, natural language search, and metadata filtering. Annotate with precision using AI-assisted labeling, RLHF workflows, advanced object tracking, native video rendering without downsampling, and frame-by-frame analysis. Build sophisticated annotation schemas with nested ontologies and dynamic attributes. Integrate SOTA models such as SAM2, YOLO and more into workflows to automate and accelerate annotation processes.
Enterprise platform with future-proof scalability
Transform petabytes of multimodal data with Encord's highly scalable architecture that handles millions of data points while maintaining SOC2 Type II, HIPAA, and GDPR compliance. Upload data once and leverage it across unlimited projects, significantly reducing storage overhead and management complexity. Choose from flexible deployment options (cloud, VPC, or on-premise/air-gapped) tailored to your organization's specific requirements.

Rigorous compliance with industry standards to protect your most sensitive data. Safeguard personal information, protected health data, and valuable intellectual property through comprehensive security protocols and data handling practices that meet the highest regulatory requirements.
Case studies
We now have an integrated, one-stop solution where we can manage our data and also understand our model performance to create feedback mechanisms to improve data and models.
Encord made it very easy to centrally keep track of annotations, including who had made them and who had reviewed them. It also has this great interpolation tool which was especially useful.
It’s always about balancing speed and quality. A lot of platforms prioritize speed over quality or quality over speed. Encord speeds up annotation while still allowing for strong quality control.
Encord’s robust support system has been remarkable. Whenever questions or issues come up, they are always supportive and helpful. This ensures that our workflows remain uninterrupted.
We went through a bunch of vendors and one of the things that stood out about Encord was the video first support, which other vendors do not have.
Getting started with Encord and integrating it into our workflow was really fast. The thing that I find the most valuable is the flexibility of how we can integrate the Encord pipeline into our own pipeline.
Encord Index is a high-performance system for our AI data, enabling us to sort and search at any level of complexity.
Before using Encord, it was challenging to see all the data, projects, and annotations in one place. Now, with Encord I feel like we have a much clearer understanding of everything that's happening.

Encord offers robust data visualization and exploration features such as advanced natural language search, embedding plots for visualizing data distributions, powerful filtering options based on quality metrics and metadata, and tools for identifying outliers and underrepresented areas in your datasets.
No. Unlike Voxel51, which requires integration with external annotation tools, Encord provides a complete, built-in annotation suite supporting multiple modalities including image, video, audio, document, text, and DICOM files. This eliminates the complexity and overhead of managing multiple tools and ensures a seamless workflow from data management and curation to annotation.
Encord offers comprehensive team management tools that Voxel51 lacks, including detailed performance analytics, task assignment capabilities, and quality control workflows. Our platform allows you to track individual and team performance metrics, identify bottlenecks in your annotation pipeline, optimize workforce productivity, and maintain high data quality standards—critical capabilities for organizations managing large-scale annotation projects.
Encord offers truly native multimodal support, including images, videos, audio, documents, text, and medical imaging formats like DICOM and NIfTI. This makes Encord the ideal platform for teams working on complex AI projects that require diverse data types and cross-modal analysis.
No. Encord makes migration straightforward with dedicated tools and support from our expert team. Our team has experience helping organizations transition from Voxel51 to Encord, ensuring you can quickly benefit from our more comprehensive platform capabilities without disrupting your existing workflows.
Forget fragmented workflows, annotation tools, and Notebooks for building AI applications. Encord's Data Development platform accelerates every step of taking your model into production.
