Sidekick is free for your whole team until 13 July

We recently introduced Sidekick, your 24/7 support engineer inside Plain.
Teams have been using Sidekick well beyond the support queue, and the pattern is always the same: a question that used to mean opening five tabs now comes back answered in one. Sidekick is the AI assistant inside Plain, the AI-native Customer Infrastructure Platform, it goes into your tools, pulls the context, and hands you the answer. Stop investigating, start resolving.
So we'd like you to put it to work across your whole team. Until 13 July, Sidekick is free for everyone — no allowance, no counting. It's a two-week window to see how your team actually uses it, how credits work, and what Sidekick can do for you before usage becomes part of your plan.
"I am absolutely blown away — this product direction is 100% aligned with how we're evolving our support team." — Dean Sliney, Head of Support Engineering @ Mintlify
What does Sidekick actually do?
Most support tooling can only answer questions about the support queue. Sidekick answers questions about your whole customer picture, because it reaches across the systems where that picture actually lives — 9+ tools at launch, including HubSpot, Attio, Linear, GitHub, Sentry, Datadog, PostHog, Notion, Granola, Incident.io, and Slack.
Ask it something that would normally mean checking Linear, then HubSpot, then a call recording, then a PR, and Sidekick pulls the thread together and answers once. Zero tabs switched. And because it's working in tools you trust, every answer comes back with its sources, a confidence level, and the reasoning attached, so you can see exactly how it got there.
Sidekick is separate from Ari, Plain's customer-facing AI agent. Ari resolves customer conversations on the front line; Sidekick works alongside your team, on the messier internal questions that don't have a one-click answer.
Why does this matter?
In nearly 40% of the teams who switched to Plain, the trigger was the same: messages falling through the cracks — lost threads, missed requests, no clear owner — with context scattered across disconnected tools. Stytch knew it well before switching:
"We had to jump between internal and external Slack channels, then to Discourse, then over to Zendesk for email."
— Christopher O'Neill, Head of Developer Success at Stytch
That jumping is exactly what Sidekick is built to erase. It's the same thesis behind Plain itself — Sourcegraph replaced three separate tools with Plain and cut first response time by 67% — now extended from where your conversations live to where your answers live.
What should you try during the free window?
The free window is the time to throw your messier questions at Sidekick — the work you wouldn't normally reach for, because it usually means too much digging. A few places to start:
"Is the bug from this thread fixed yet?" Trace a customer report straight through to the related issue or PR.
"Where do things stand with this account?" Pull customer, deal, and history into one answer before a call.
"What's behind this spike in alerts?" Spot patterns across your whole customer base before they become a queue full of tickets.
The point of the next two weeks is to learn where Sidekick earns its place in your workflow, with no usage to ration while you find out.
What happens on 13 July?
On 13 July, Sidekick becomes part of your Plain plan. Each plan includes a monthly credit allowance, and you'd only pay more if you go beyond your included usage.
Plan | Credits included / month |
|---|---|
Foundation | 2,000 credits |
Horizon | 15,000 credits |
Frontier | 50,000 credits |
Sidekick is the only feature in Plain that uses credits today. Everything else stays as it is.
How do Sidekick credits work?
Usage tracks effort, not volume. A quick summary costs far less than a deep, multi-source investigation, so a credit allowance goes a long way on everyday questions and only draws down meaningfully on the heavy lifts.
You can watch your usage in real time in Settings → Billing, so there's never a surprise at the end of the month. Full details (including how different question types are metered) are in the Help Center: How Sidekick usage credits work
Questions?
We're here to help. If anything about the free window, credits, or your plan's allowance is unclear, just reach out and we'll walk you through it.
Until then, open Plain and give Sidekick the questions you'd normally dig out by hand. Two weeks, zero tabs, no counting. That's the whole point.
