Build support your way
Break free from the duct tape, the rigid workflows, and the lock-in. Plain is AI support infrastructure that enables B2B teams to build anything – no-code or all-code.
HUNDREDS of fast-moving teams rely on plain
Your customers are talking to you in Slack, MS Teams, email, and inside your product – and your team is jumping between all those places. Insights are scattered, and each "new support tool" imposes their opinions on you.
But what if it was different?
Meet a new approach:
Support Infrastructure
Channels
Consolidate support
Connect and scale Slack, Microsoft Teams, Discord, email, chat, portal and more.

Get the latest, every day

Speed, meet power.
We get it. When you’re comparing platforms, they all look the same. We’ll make it easy for you. Here’s why, and when, we win.
When you need performance and scale
Plain is designed for work, not to feel like work. Every aspect of the Plain interface has been forged, stress-tested and iterated on by and with some of the fastest-growing, and most demanding support teams in the world. They love it, and we think you will too.
When you demand complete extensibility
We give you flexible building blocks, not rigid opinions. Plain is API-first, so everything you see in the product can be done programmatically. Extend workflows, automate the edge cases, or replace entire pieces with your own logic. If you can imagine it, you can ship it.
When you want to enjoy the buying process
Seriously. People often choose us because working together feels straightforward. We know you are not switching platforms all day because you love it. So we focus on clarity, honest guidance and removing friction. Our sales team knows the product deeply and works with you to get to a yes or no quickly, whichever is right.
Start fast. Scale fearlessly.
Plain isn’t just faster, it’s built to last.
Fast growing companies love plain
Take their word for it
With Plain powering our support, we don't have to think about scaling challenges. Everything just works.
