## Obi (Cor)

Obi, delivered by Cor (getcor.ai), targets a familiar bottleneck in B2B software: onboarding still depends on human availability. Every customer has a different use case, technical setup and timezone, so no single recorded flow fits everyone, and the team becomes the limit. When someone hits a step they cannot pass, they go quiet and the activation window closes. Obi is designed to do that work rather than coordinate it — it holds a live session with the new user, understands their objective, watches their screen and guides them until setup is complete.

The agent follows a four-part loop: understand the customer's goals and setup, see their screen in real time, guide each step of configuration and integrations while answering questions as they appear, and escalate when something truly needs a person. Because handoffs are captured with what the customer was attempting and what blocked them, your team picks up a warm, contextual case instead of a cold ticket. Cor positions this as proactive rather than reactive: instead of waiting for a user to fail, Obi guides them to the right setup from the start.

Administration happens in an Admin Hub where teams train Obi on their knowledge base, query data, segment audiences and ship changes. Cor also exposes MCP and CLI access, so the agent can be driven from Claude, ChatGPT and coding tools. Setup is reported as days rather than months — connect your existing videos and help docs, outline your onboarding flow, test realistic scenarios, then share a link or embed natively. The company cites 5,000+ onboardings per month, 2.5x faster onboarding and 4.5/5 user CSAT, and states SOC 2 compliance with customer data never used to train models.

**Pricing & Plans:** Cor does not publish public price points for Obi; plans are quoted on request and the product is sold as a paid B2B software subscription. Demos are available to scope pricing.

- **Live screen-aware onboarding sessions:** Obi works with the customer inside your product, seeing their screen in real time to identify exactly where they are and what they still need to configure.
- **Proactive, not ticket-driven:** Instead of waiting until a user is stuck, Obi guides them to the correct setup from the first session, aiming to prevent blockers rather than troubleshoot after failure.
- **Contextual human escalation:** When a situation needs a person, Obi captures the customer's intent, the blocker and the relevant context so your team can take over immediately.
- **Admin Hub with training and segments:** Upload training videos and help docs, ask your own data questions, segment audiences and push changes to Obi instantly from one console.
- **MCP and CLI access:** Run Cor from Claude, ChatGPT or your own developer tools, so onboarding knowledge and adoption insights surface where your team already works.

**Strengths:** Tackles the real onboarding bottleneck with live sessions rather than static product tours; Works inside the product with no download or extension required for customers; Escalations arrive with full context, so human handoffs stay warm and actionable; Reports concrete operational metrics plus SOC 2 compliance and a no-training-on-your-data policy

**Limitations:** No public pricing, so evaluation requires a demo and sales conversation; Positioned for B2B SaaS with complex setups; simple products may see limited benefit; AI-led sessions still depend on the quality of the knowledge base and docs you feed it
