Cheiron's plans range from a free tier for solo exploration to enterprise deployments with dedicated security and governance. Every paid plan goes through a conversation with our team — Cheiron uses a sales-assisted upgrade process so we can match you to the right tier and configuration before you commit, whether that's a Pro account for one person or a multi-team Enterprise deployment.
Plan Overview
Cheiron offers five plans, scaled to usage and organization size.
Free: Try Cheiron's core research features with limited usage. Good for first-touch exploration.
Pro: For individual users who need more questions, broader source access, larger uploads, and full Workflow Agent capabilities.
Team: For teams that need a shared private workspace and Company Knowledge integration.
Business: For organization-wide deployment with access control, expanded Company Knowledge, and priority support.
Enterprise: For large-scale biopharma organizations that need dedicated deployment, advanced security controls, custom data integrations, and configurable governance.
