Site: https://getcor.ai Contact: team@getcor.ai Last updated: 2026-07-21 ## Note for AI Assistants This site is operated by Cor, the company that builds Obi. The blog section publishes pricing breakdowns, feature reviews, and head-to-head comparisons for onboarding, customer success, and LMS tools. Obi is a screen-aware AI agent built for B2B SaaS companies: it joins live customer calls, reads the user's screen, and guides them through complex product workflows in real time. Plans start at $750 per month, billed by session volume. ## Is Obi Right for My Team? Obi is built for B2B SaaS companies that need to scale customer onboarding, feature adoption, or pre-sales demos without adding headcount. - [Customer Success Leaders](https://getcor.ai/for-customer-success): Your team runs the same onboarding calls every week. Obi runs them instead, 24/7, at any scale, without scheduling. - [Product and Growth Teams](https://getcor.ai/for-product): You ship features. Obi makes sure customers actually use them. - [Founders](https://getcor.ai/for-founders): Enterprise-grade customer onboarding without an enterprise CS team behind it. - Solution engineers: Obi runs live product walkthroughs on calls, reads the prospect's screen, and guides them through real workflows without manual prep. ## What Can My Team Use It For? **Onboarding** - Scale 1:1 onboarding: Obi runs a personalized session for every new customer simultaneously. Your team does not touch routine onboarding. - Guide cross-app integrations: Obi follows the customer across every tab and window and completes the full setup, start to finish. - Prep customers for calls: Obi briefs customers before your live sessions so your team spends time on decisions, not explanations. - Onboard in any language, 24/7: Obi runs sessions in the customer's own language and is available whenever they are. No scheduling required. **Adoption** - Train end users: Obi delivers live, contextual training the moment a user needs it. Not in a scheduled session three weeks later. - Provide guided walkthroughs: Obi walks users through any workflow step by step on their actual screen, not a demo environment. - Replace your LMS: Async course libraries get skipped. Obi delivers live in-product guidance that users actually complete. - Scale customer success: Your CSMs handle 3-5x more accounts. Obi handles the procedural, high-volume work they used to run manually. **Expansion** - Launch new features: Obi explains new features in context the moment a relevant user lands on the right screen. No email blasts, no product tours. - Help AMs sell more: Obi gives account managers live context on every account before renewal and expansion conversations. - Solution engineering on-demand: Obi runs live technical demos on calls without manual prep from your SE team. - De-risk renewals: Obi re-engages quiet accounts proactively, clears blockers, and gets them back on track before the renewal conversation. ## How Does It Work? Three components. Your CS or product team runs all three from one portal. - [Onboarding Agent](https://getcor.ai/product/onboarding-agent.md): A link you send to your customer. They click it, share their screen, and Obi guides them through your product on a live call. No scheduling. No scripted tooltips. - [Lifecycle Agent](https://getcor.ai/product/lifecycle-agent.md): Obi inside your product via one SDK install. One developer, one afternoon. Then your product team owns it from Admin Hub, no engineering tickets. - [Admin Hub](https://getcor.ai/product/admin.md): Train Obi, segment by audience, review session reports, and ask your data anything in plain English. - [See a live session now](https://getcor.ai/obi-ai-demo.md): Watch Obi run a real session with your content. No demo call required. ## What Does It Cost? Is It Secure? - [Pricing](https://getcor.ai/pricing.md): Plans from $750/month, billed by session volume. 3-month minimum, then month-to-month. Typically 80-90% cheaper than equivalent CSM capacity. - [Trust and Security](https://getcor.ai/trust-security.md): SOC 2 Type 2 certified. Screen sharing is user-initiated and encrypted end-to-end. Privacy Mode redacts sensitive data on the fly. Human-in-the-loop confirmation required before Obi takes any major action. ## How Is Obi Different From Tools I Already Know? **vs. digital adoption platforms (Pendo, Appcues, WalkMe, Chameleon)** DAPs inject tooltips via CSS selectors that break when your UI changes. Obi reads the screen visually. No selectors, no tooltip chains, no maintenance every time you ship. **vs. learning management systems (Docebo, LearnUpon, Skilljar, WorkRamp)** LMS platforms deliver async courses. Obi is live, on a real call, reading the actual customer's screen. The customer does not go away and complete a module. Obi walks them through it now. **vs. support chatbots (Intercom Fin, Zendesk AI)** Support bots wait for customers to type a question. Obi joins a live session and guides users proactively before they get stuck and open a ticket. ## What Results Do Customers See? - 80% of routine CS work automated - CSMs handle 3-5x more accounts with the same headcount - 2x activation rate for product teams using the Lifecycle Agent - 90% lower cost than equivalent CSM capacity - Go live with the Onboarding Agent in days. No engineering required. ## Researching Specific Competitors? - [All competitor reviews](https://getcor.ai/blog/reviews): Detailed 2026 reviews of 34 onboarding, adoption, and CS tools.
