Customer support is changing fast. Teams are expected to handle more volume, answer increasingly technical questions, and surface clearer insights — all without growing headcount.

Most tools only solve pieces of that puzzle, leaving support teams to connect the dots.

Plain is changing that.

Today, we’re launching four AI capabilities that work together as one system — automating repetitive work, answering complex questions instantly, and surfacing patterns that guide your product decisions.

Here's what's new.

Ari: Automated Support You Can Actually Trust

Your team shouldn’t spend time answering basic questions for the hundredth time. But most automated support tools create an even bigger problem: wrong answers, hallucinated responses, and damaged customer relationships you now have to repair.

We built Ari to avoid all of that — a solution that actually deserves your trust.

Ari handles customer requests automatically, but only answers what it can verify from your docs, past tickets, or help content. No guessing. No improvising. No hallucinations.

And you stay in full control.

You decide exactly when Ari should reply and when it should hand off to a human. The new Activity page shows every conversation Ari handled or escalated, so you always know what’s happening.

What this means for your team: Ari handles the scale. Your team handles the work that matters.

Lookup with Cursor: Code-Accurate Answers in Minutes

Here's where Plain does something no other support platform can: Cursor Lookup connects your support team directly to your codebase.

Support teams face technical questions every day — errors, edge cases, “is this expected” moments. The real answers live in the code, and getting them usually requires an engineer’s time or an escalation.

We built Cursor Lookup to empower support teams with engineering-level clarity, instantly. When a customer reports an error, Cursor Lookup reads the relevant code, understands the context from the ticket, and tells your team exactly what’s happening.

Instead of escalating support requests because documentation doesn’t exist, your support team can now get definitive, code-based answers in minutes. For confirmed bugs, it can even help automate the fix.

What this means for your team: Fewer escalations, faster resolutions, and a support experience rooted in facts. It's the bridge between support and engineering that actually works.

Sidekick: Your Team’s Co-Pilot

Support work is full of friction — searching through old tickets, trying to remember where that one doc lives, digging for context, and helping new teammates get up to speed.

Sidekick is here to support you.

Sidekick lives directly in the inbox and gives your team what they need, exactly when they need it. It drafts responses, summarizes long threads, surfaces the right docs, and shows how similar issues were handled before — all without breaking the flow.

For new hires, Sidekick is like having an experienced teammate guiding every reply. For senior agents, it removes the repetitive tasks that slow them down.

And because Sidekick uses the same knowledge base as Ari, your automated and human responses stay consistent.

What this means for your team: Support gets the support it deserves, and your agents work with more confidence.

Insights: From Conversations to Roadmap

Your support team sees every customer pain point, feature request, and bug report before anyone else. But that signal stays buried in individual tickets, impossible for product teams to act on.

Insights changes that. It automatically analyzes your support conversations and surfaces patterns that actually matter — grouping similar issues and connecting themes to company data. What used to take hours of manual work now happens instantly.

No more spreadsheets. No more manual tagging. No more wondering if that feature request came from one loud customer or fifty quiet ones.

What this means for your team: You build what customers actually need, not what you think they need.

The Future of Support

Support teams have always been the closest to the customer, but the tools around them have rarely supported them in the way they deserve. This launch is a step towards changing that.

These aren’t four separate tools. They’re one intelligent system.

• Ari handles the repetitive volume

• Cursor Lookup answers technical questions before an escalation is needed

• Sidekick supports your team when complexity requires judgment

• Insights learns from every interaction and surfaces what matters most

This is just the beginning of what we’re building at Plain — a system built on trust, accuracy, and transparency. Human-in-the-loop by design, with complete context at every step.

All four features are available today. Whether you're already using Plain or exploring what modern support can look like, we’d love to show you how it all works.
