# HumanSignal
> HumanSignal provides data infrastructure and human data services for teams building AI. Pricing spans Data Services engagements (custom-scoped data collection, annotation, and evaluation performed by domain experts), the hosted Starter plan, Label Studio Enterprise in compliant cloud or on-prem deployments, and the free open source Label Studio Community Edition.
HumanSignal is the company behind Label Studio, the open source data labeling platform used by more than one million AI practitioners. The same team that builds the tooling also operates a human data services business, so services engagements run on infrastructure purpose-built for multi-modal data, with advanced quality and inter-annotator agreement workflows and data privacy built in.
## Data Services
Data Services covers from-scratch data creation, annotation, and evaluation, delivered with end-to-end project management. Engagements are custom-scoped and priced per project; the starting point is a scoping call rather than a published rate card.
- [Book a scoping call](https://humansignal.com/contact/): Talk to the team about a data project.
- What is offered:
  - Data collection from scratch, in HumanSignal's physical data collection studios or through a global network of data collectors and content creators. This includes multi-modal collection such as video, audio, images, and sensor data, with recent specialization in egocentric video for physical AI and robotics.
  - Expert annotation across text, image, audio, video, and multi-modal data, including multilingual annotation and complex schema work.
  - Model evaluation by domain experts, with particular depth in graphic design and creative work. Customers include Canva.
- Who it is for: technology companies building models, including frontier AI labs, robotics companies, and product teams shipping AI features, as well as enterprises developing their own models.
- How it works: projects are scoped with the delivery team, managed end to end by HumanSignal, and executed on Label Studio Enterprise, which gives clients task queuing, QA workflows, agreement metrics, and compliance controls over the work as it happens.
## Platform Plans
Three editions of the Label Studio platform:
- [Community Edition](https://labelstud.io/): Free and open source. Multi-modal labeling, configurable interfaces, templates, ML backend integration, API/SDK, and cloud storage connections. Self-hosted.
- [Starter](https://humansignal.com/pricing/): $99 per user per month, up to 12 users. Fully hosted Label Studio with role-based access control, quality workflows, review and verification, automated task distribution, Interfaces (see below), and a support portal.
