Today, I’m excited to share 12 major updates to Fin’s Procedures and Simulations—the foundation that lets Fin handle complex work while keeping teams fully in control of the customer experience.
In my work building AI workflows with product and support leaders, I’ve seen how the right blend of natural language instructions, deterministic controls, and fully agentic behavior turns Fin into a reliable problem solver. Procedures make this blend possible by enabling Fin to act like a human—yet with the repeatability and governance of software. Simulations then let us test those complex Procedures at scale before they reach customers, so we can deploy with confidence.
Together, these capabilities make Fin self-manageable, transparent, and ready for genuinely complex work.
Here’s what’s new at a glance: we’ve made Procedures easier to build and maintain; enhanced deterministic controls for precision and policy compliance; expanded agentic behavior so Fin can adapt in real time; and delivered more powerful Simulations to validate end-to-end workflows before go-live.
Why did we build this? Many teams see early AI gains in speed, coverage, and cost to serve—but then hit a ceiling. They keep AI confined to simple automation and information retrieval, rather than setting it up to handle the nuanced, multi-step workflows they still trust to humans. We designed Procedures and Simulations to remove that ceiling, so teams can confidently set up, govern, and iterate on complex AI workflows without bottlenecks.
We also heard that teams needed an easy way to connect data so Fin could reliably check customer status or eligibility and then take action. And they didn’t want to route through engineering every time they needed to create or amend logic for mid-conversation decisions. Procedures combines natural language instructions and intuitive data connector setups. You tell Fin in your own words how you want it to behave, and you’ll be guided through creating conditional steps so Fin will react consistently, with the option to add in any code snippets for circumstances where absolute precision is required. Once you build one Procedure, we believe you’ll want to build several, so Fin will constantly read the conversation it’s in to ensure it’s following the most relevant Procedure, and jump to a more relevant one if the user intent changes.
I know that taking something like this live the first time can feel like a leap of faith. That’s exactly why we built Simulations—to test Procedures comprehensively, uncover edge cases, and launch with confidence.
Reaching mature deployment takes a deliberate, ongoing commitment to training workflows, validating them before deployment, measuring performance in production, and refining them over time. At Intercom, we call this the Fin Flywheel: train, test, deploy, analyze. Procedures form the foundation of the train stage, and Simulations make the test stage reliable at scale. Together, they enable Fin to handle complex work, and teams to stay in control of it.
Procedures: Define exactly how Fin handles complex work. With Procedures, I can set Fin up to resolve complex, time-consuming queries that require multiple steps or business logic. Fin follows standard operating procedures and applies sound judgment—just like a seasoned teammate—so even complicated queries are resolved in controllable, predictable ways.
Procedures combine three powerful elements. First, natural language instructions. You write a Procedure in plain language, just like documenting a process for a new teammate. You can paste in your existing SOPs, write from scratch, or let AI draft them for you, then iterate yourself.
What’s new: Draft Procedures with AI. Share an outline of your process and Fin drafts a complete Procedure using your conversation history, knowledge hub content, and relevant data. If additional context is needed, it prompts you with clarifying questions to make sure the Procedure is thorough and tailored to your use case, significantly reducing setup time. For example: if you’re creating a refund workflow, the system can draft conditional paths for eligibility, approval thresholds, and verification steps based on your historical cases and policies.
What’s new: Break complex workflows into Sub-procedures. Write a process once and reference it across multiple Procedures by breaking it down into reusable steps, called Sub-procedures. This makes workflows easier to read, faster to build, and simpler to maintain as things change.
Second, deterministic controls. Natural language is flexible, but some steps need to be exact. You can layer in deterministic controls where precision matters, starting with a fully natural language Procedure and introducing structure gradually where it adds value: conditional steps (branching logic) to handle decision points so Fin’s behavior is consistent and predictable; data connectors so Fin can pull information from your tools or take actions automatically; code snippets for when absolute accuracy is essential; and checkpoints to pause for approval or hand off to a teammate.
What’s new: Instruct Fin to read specific content from your knowledge hub. You can set clear rules for Fin to reference a specific policy or article from your knowledge hub in defined situations so Fin always surfaces the right context in a conversation.
What’s new: Explicit Procedure switching under defined conditions. You can set rules that deterministically trigger a switch to a different Procedure, for example, escalating to a complaints Procedure if specific risk signals are detected mid-conversation.
What’s new: Internal notes for human handoffs. When Fin hands off to a teammate, it can now include internal notes with relevant context so the person picking up the conversation knows exactly what happened and what needs to happen next.
Third, fully agentic behavior. Because real conversations rarely follow the happy path, Procedures let Fin reason through what’s happening and adapt—jumping to the right step or switching Procedures entirely if a customer changes their mind or the issue shifts.
What’s new: Automatic Procedure switching. If a customer starts in a billing workflow but then asks about cancelling their subscription, Fin transitions to the relevant Procedure without forcing the customer to restart.
What’s new: Structured data extraction from uploaded files. Fin can now extract structured data directly from PDFs and images uploaded by customers—like invoices, forms, or receipts—and use that data within the conversation. Customers don’t have to copy and paste or repeat themselves.
As MONY Group put it:
“ If a customer starts down one path but their issue turns out to be something else entirely, Fin adapts seamlessly – no more getting stuck in loops or forcing customers into the wrong workflow. ”
The result is a conversation that feels fluid, but always follows your intended rules.
Making complexity easier to manage is just as important as unlocking new capabilities. Beyond the core updates, we’ve focused on creation, governance, and scale—while keeping ownership with your team.
What’s new: Improved instruction authoring. We’ve made it easier to write, edit, and structure Procedures, so building and updating them takes less time and requires less effort.
What’s new: Reporting on when Procedures trigger, resolve, or hand off. You can now track how Procedures are performing directly within the Procedures UI, seeing exactly when they trigger, when they resolve, and when they hand off to a teammate. This visibility helps you spot issues early and improve over time.
Simulations: Test complex workflows at scale before they reach customers. Simulations let you validate how Procedures will perform before anything goes live, and continuously revalidate as things change. Deploying complex AI can feel uncertain; Simulations remove that uncertainty so you can launch with confidence and iterate safely.
You can simulate full conversations. For any Procedure, choose a user or customer segment and run a complete, multi-turn simulated conversation. You see every step Fin takes, how it applies your rules, reasons through decisions, and where it passes or fails—giving you the observability to debug and fix issues before they ever reach customers.
What’s new: Upload images for richer testing. Simulations now support image uploads, so you can test workflows that involve receipts, invoices, or forms—the same inputs your customers actually send.
What’s new: Clearer visibility into Fin’s reasoning. You can now see exactly how Fin is thinking through each step of a Simulation, making it easier to understand behavior, catch unexpected decisions, and refine Procedures with confidence.
You can also use AI to create, store, and rerun tests. Writing test coverage manually doesn’t scale. Fin’s AI Assistant generates Simulations directly from your Procedures, suggesting realistic edge cases like partial refund disputes, missing invoice uploads, or no subscription found, so you can expand coverage without expanding overhead. All the Simulations you create are stored in a central library. When a product changes, a policy updates, or a Procedure is edited, hit “run all” to instantly check whether anything has regressed. This applies the same rigor to AI automation that engineering teams bring to software testing.
What’s new: AI-suggested Simulations. You can now use AI to generate a full set of Simulations from any Procedure. The AI Assistant suggests realistic variations based on your workflow, so you can build comprehensive test coverage fast.
Customers are already seeing this in production. “Fin can now handle payment-related queries that were never possible before… The impact on CSAT and overall CX has been pretty shocking – the Payment Information procedure CSAT is sitting at ~94%, and CX score is significantly higher than our average.” – Raylo
“Procedures have fundamentally changed what we can achieve with Fin. Previously, complex processes like cashback claim investigations could only be handled through a static form on our website… Now, Fin can handle these sophisticated scenarios in real-time within the conversation itself. It checks account information via API calls, makes complex decisions, and guides customers through the entire claims process dynamically.” – MONY Group
Procedures and Simulations are available now. I’m eager to see how teams use these updates to scale agentic AI, deliver faster resolutions, and raise the bar for customer experience—without sacrificing control, compliance, or quality.
