Data infrastructure for Physical AI and multimodal teams: annotation, curation, alignment and managed data, used by 300+ AI teams, per the vendor.
Encord is aimed at robotics, autonomous-vehicle and medical-imaging teams that want one platform to annotate, curate and evaluate multimodal data, with managed data services on top. Its docs list 48 dated changes this year, Merlin is still beta, and a quote is the only way to cost it.
One platform that labels video, LiDAR and DICOM data, curates it and feeds model evaluation and alignment, with Physical AI collection services on top.
Modality breadth and the move into collected Physical AI data create switching costs for robotics and medical teams, but the core annotation workflow is replicable and its open-source Active toolkit was archived.
Main trade-off
No published price and add-on data types make cost impossible to compare without a sales conversation.
| Plan | Monthly price | What it includes |
|---|---|---|
| Starter | Custom | Image and video annotation toolkit, Complex and dynamic ontologies, Customizable workflows, Self-serve support, Index up to 500k, Active up to 50k |
| Team | Custom | Everything in Starter, Data agents, Performance analytics, Model evaluation, Onboarding support, Index up to 100m, Active up to 1m |
| Enterprise | Custom | Everything in Team, Multiple workspaces, Single sign-on (SSO), Enterprise SLA and support, VPC and on-prem deployments, Index 1bn+, Active up to 10m |
Encord prints no price for any plan. It lists Starter, Team and Enterprise, with a Get started button on the first two and Contact sales on Enterprise, and data volume limits that rise by plan: Index up to 500k, 100m and 1bn+, Active up to 50k, 1m and 10m, in the units the page prints. DICOM and NIfTI, 3D, LiDAR and point cloud, geospatial, ECG, LLM evaluations, custom data, on-prem deployment, a solutions architect and a custom MSA and SLA are marked as add-ons, so a quote depends on the data types chosen.
| Feature | Team | Starter | Enterprise |
|---|---|---|---|
| Index data volume | Up to 100m | Up to 500k | 1bn+ |
| Active data volume | Up to 1m | Up to 50k | Up to 10m |

Encord is a data infrastructure platform for Physical AI and enterprise teams, founded in 2021, that annotates, curates and evaluates images, video, audio, documents, DICOM and LiDAR data. The vendor names Woven by Toyota, AXA, UiPath and Zipline among its customers.
Multimodal annotation
One workflow for image, video, audio, document, DICOM, NIfTI and LiDAR annotation, although several of these types are listed as add-ons on the pricing page.
Model-assisted labeling
Imports model predictions, uses Segment Anything Model 2 and tracks objects across frames, and added one-click point-cloud segmentation and cuboids on 13 August 2026.
Index for curation
Searches and curates datasets with multimodal search, outlier and duplicate detection and embeddings, with volume limits that rise by plan.
Active for label and model analytics
Finds label errors, compares models and runs active learning pipelines, with its own volume limits per plan.
Data agents and SDK
Runs custom agents inside workflows through the encord-agents SDK, which gained signed task-ready webhook notifications in September 2026.
Post-training alignment
Orchestrates RLHF, rubric-based evaluation and pairwise comparison to find where production models fail and route the data back into training, per the vendor.
Merlin agent layer (beta)
Builds projects, reshapes ontologies and live workflows and reports analytics by chat or MCP; the docs label it BETA and exclude on-premises and air-gapped deployments.
Data-as-a-Service
Supplies vetted expert annotators and in-field and teleoperation data collection integrated with the platform.
Most users expect these and they are not currently supported.

Proprietary; with cloud integration, customer data stays in the customer's own cloud storage
No Encord plan carries a published price. The three tiers are Starter, Team and Enterprise, and the pricing page shows Get started under Starter and Team but Contact sales under Enterprise. Medical imaging, 3D and LiDAR, geospatial, ECG and LLM-evaluation data types are sold as add-ons, so a quote depends on which data types a team needs.
Neither the pricing page nor the docs name a free plan or a trial, so the cheapest way in is a Starter quote or sign-up. The open-source Encord Active repository, licensed Apache-2.0, is archived on GitHub with its last push on 23 May 2025, which makes the free self-hosted route read-only.
Yes. Encord says its platform does not store your data when you use cloud integration: it requests temporary signed URLs from your bucket, and it recommends a private cloud integration so files stay in your own storage. Data it does hold is encrypted at rest with AES-256 and in transit with TLS 1.2 or 1.3, per its security page.
Merlin is Encord's agentic layer, labelled BETA in the docs. It can set up annotation projects, adjust ontologies and workflows, report analytics and search the documentation, in the Encord app or through MCP in tools such as Claude. It needs a cloud account and is not available on on-premises or air-gapped deployments.
Its homepage and llms.txt lead with Physical AI such as robotics, autonomous vehicles, drones and world models, but the same platform lists healthcare, frontier AI, defence, sports and voice AI solutions. The research side is moving the same way: EMG-1, released on 20 October 2026 with Encord Data Labs, pairs muscle-signal recordings with first-person video.
Encord began as a labeling tool for computer vision and now describes itself as the data infrastructure layer for Physical AI and enterprise AI teams. It was founded in 2021 as Cord Technologies by Ulrik Stig Hansen and Eric Landau, is headquartered in London with offices in San Francisco and New York according to its llms.txt, and has raised $110 million in total, including a $60 million Series C led by Wellington Management in February 2026. Venture Burn reported that data volume on the platform grew from about 1 to more than 5 petabytes in 12 months, and Encord says more than 300 AI teams use it, among them Woven by Toyota, Toyota Research Institute, AXA, UiPath and Zipline.
The platform has four working parts. Annotate labels images, video, audio, documents, DICOM and NIfTI medical imaging, and 3D, LiDAR and point-cloud data, with model-assisted labeling from Segment Anything Model 2 and object tracking. Index searches and curates large datasets with embeddings, outlier and duplicate detection, and Active analyses label errors and model performance. Post-training alignment adds RLHF, rubric-based evaluation and pairwise comparison for models already in production. Around them sit Data agents, a Python SDK and the encord-agents repository, Merlin, an agentic layer that the docs label BETA and that works in the Encord app or through MCP, and a managed Data-as-a-Service line of vetted annotators and in-field data collection.
Encord fits ML and data teams building robots, autonomous vehicles, drones and medical-imaging models, and frontier-model teams that need alignment data. Its own customer stories claim that Forterra sped up model iteration by 50 percent and that UiPath grew a dataset tenfold while cutting its error rate fourfold; both are vendor claims. On 20 October 2026 it released EMG-1, an open dataset of more than 300 hours of muscle-signal recordings paired with first-person video, built with Wearable Devices and launched alongside Encord Data Labs, its new Physical AI research division.
Buyers should look at alternatives when they need a published price, a free way in or a narrow job. Superb AI sells labeling and curation to industrial and mobility teams, Surge AI supplies expert human data for RLHF, and Scale AI is the larger managed-data vendor; search results for Encord alternatives on 11 November 2026 return roundups that name Labelbox, SuperAnnotate and V7, and none of the three has a Hokai record yet. Several data types sit outside the base plans on its pricing page, including DICOM and NIfTI, 3D, LiDAR, geospatial, ECG and LLM evaluations; Merlin is not available on on-premises or air-gapped deployments, and the open-source Encord Active repository is archived. For a first-hand look, on 11 November 2026 GitHub showed the encord-agents repository pushed on 10 November, the encord-client-python SDK on 28 October, and encord-active archived with its last push on 23 May 2025. More tools in this category are on the data science and ML platforms list, and best data science and ML tools compares the wider field.
The 2026 release notes carry 48 dated entries through 9 November. Merlin became native in the Encord app on 13 August and gained a default sidebar on 9 October, point-cloud labeling got one-click segmentation and cuboids on 13 August, Task Rules and the Metadata Router reached general availability on 8 and 2 September, the Timeseries modality on 16 October and project-level Issue Management on 5 November.
Product facts on this page (pricing, plans, integrations, compliance) are read from Encord's own pages and documentation. The verdict is Hokai's reading of them, not the vendor's claim.
