## Ways to pay less

- **50% off Horizon for early-stage startups** (Startups): A $6,000 flat fee covers 12 months and 10 seats of Horizon. Eligibility is VC-backed up to $5 million in funding, 10 or fewer on the support team, and not already a customer. Source: https://www.plain.com/startups
- **20% off Foundation with annual billing** (Annual discount): The pricing page shows Foundation at $45 per user a month billed annually against $55 billed monthly, labelled a 20% saving. Source: https://www.plain.com/pricing

## Key features

- **Sidekick Agent:** An AI agent for the support team that uses 15 to 300 or more credits a task depending on effort.
- **Slack and email channels:** Support threads come in from Slack channels, email addresses, in-app forms and live chat, with Microsoft Teams and Discord on higher plans.

## Good for

- AI credits are limited per month (1,000 on Foundation, 2,500 on Horizon); extra credits are $10 per 1,000 up to $100 per 10,000.
- SLAs, escalation paths and Microsoft Teams need Horizon at $99 per user / month; SSO, SCIM and HIPAA need Frontier.
- Plain lists a startup program with a $6,000 flat fee for Horizon, 10 seats and 12 months, for early-stage teams of ten or fewer.

## Keep it, or make your own?

**Keep it.** To replace Plain you would be making one mailbox that several people work at once. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 42 of the 66 other help desk and live chat tools grade higher. It costs $540 a year.

- You could make: Help desk and help center: an app builder makes these well.
- You could not: One mailbox that several people work at once.
- You could not: An AI model answering your customers from your own help articles.
- You could not: Connections to other products, each kept working as those products change.
- You could not: A chat box on your site that reaches you the moment a customer types.
- You could not: It is priced for each person, which means accounts and billing for a team.
