Why teams choose Plain over Fin
Both resolve support with AI. The difference is who each is built for: Plain is for B2B teams supporting technical customers.
The top reasons why B2B teams choose Plain
Built for B2B, not B2C.
Plain is purpose-built for B2B support, with tenants, tiers, SLAs and live account context. Intercom is getting acquired by Salesforce, and its own co-founder called the deal “a major win for consumers of the world.”
Freedom over your AI.
Fin’s AI agent, runs on Apex, their proprietary model. On Plain, the agent working your queue can be ours, the one your engineers wrote with the model you want, reaching systems no vendor will expose for you. Or you can use Fin.
A roadmap that’s still its own.
Salesforce is buying Fin and folding Fin into Agentforce as the “fast-to-value” option it says suits “SMB and some commercial organizations.” Plain is independent, and B2B support is the only thing we build.

scaled in support capacity with AI handling 60% of tickets.

How we make migrating to Plain easy.
Migrating a system of record isn’t what anyone gets excited about. So here’s what the process actually looks like, specifically.
We buy out your contract.
Stuck mid-contract with Fin? We cover the overlap so you’re not paying two vendors at once.
We create an action plan.
Migration is a reset, not a lift-and-shift. We talk through what you’re actually trying to achieve, and help you build the experience your team and customers need.
We migrate your history.
Plain has a native Fin importer, so conversation history comes with you. Help center content moves too; we’ll walk you through what that looks like before you commit.
Where Fin may be a better fit.
You need in-product engagement, not just support.
Product tours, banners, surveys, carousels, mobile push and outbound email campaigns are Fin’s home turf, bundled as Proactive Support Plus at $99/month. Plain is a support platform: it answers, it doesn’t campaign.
Your customers are on consumer channels.
Phone, WhatsApp, SMS, Telegram and Instagram/Facebook DMs are native Fin channels. On Plain they’re custom channels you build through the API.
You’re a brand-new startup watching year-one cash.
Fin’s Early Stage program gives eligible startups 93% off year one at $33/month with 300 free Fin outcomes a month. Plain’s startup program is 50% off. If year-one price is the deciding factor, Fin wins that one outright.
Questions
and answers.
Frequently asked questions we get when comparing Plain and Fin.
What’s the actual difference between Plain and Fin?
Shape, more than features. Fin is an all-in-one customer engagement suite: a Messenger, a help center, outbound campaigns, product tours and consumer channels, with Fin as the AI agent across them. Plain is customer infrastructure for B2B support: every record, routing rule and button in the UI is also an API endpoint, the account model is built on tenants and tiers, and the AI working your queue can be ours or yours.
