Doerchat (formerly Doerplan) vs Koast (formerly AdCopy.ai)

Doerchat gives SaaS teams a shared inbox for chat, email, and helpdesk tickets with customer data pulled in from Stripe and your product database. You see subscription status, billing dates, seat counts, and usage stats next to every conversation, so replies do not require tab-hopping between tools.

Flat-rate pricing at $29 per month with no per-seat fees is the main differentiator against Zendesk and Intercom, which charge per agent and gate features behind enterprise tiers. Doerchat includes unlimited customers, team members, conversations, and helpdesks on every plan, plus AI agents trained on your FAQs and docs, automations, changelogs, and multi-brand switching from one account.

The platform targets SaaS founders and small support teams who need full helpdesk features without enterprise pricing. A 14-day free trial starts without a credit card, and the inbox is built for teams handling sudden growth without adding headcount.

Koast puts every Meta ad account, buyer, and creative pipeline in one workspace with agents handling triage, stop-loss cuts, and launch prep overnight. Visiting adcopy.ai redirects to Koast, which replaced the older AdCopy.ai copy generator with a full performance marketing operating system.

Copy generators stop at text. Koast runs the buying loop: agents triage accounts, pause overspending ads on five-minute stop-loss rules, audit creative fatigue, and stage budget scales for human sign-off. Batch launch queues hundreds of ads across accounts with shared post IDs, auto-grouped aspect ratios, and metadata wiping before upload.

The product targets agencies and in-house teams spending roughly $50k to $5M+ per month on Meta ads. Growth is self-serve with a 7-day trial and up to 10 ad accounts; Enterprise adds unlimited accounts, unlimited agent credits, and done-for-you onboarding. Integrations include Meta, Slack, Frame.io, Google Drive, Dropbox, and Cometly attribution data.
