Invent
Invent's per-message pricing means cost tracks usage directly instead of a flat seat fee, which suits a business that cannot predict volume in advance. The channel coverage (WhatsApp, Instagram, TikTok DMs, Telegram) is wider than most customer-service AI tools, though the 300-plus prebuilt actions still need to be wired to a business's actual systems before the assistant can do anything beyond answering questions.
Pros
- Single assistant covers WhatsApp, Instagram, Messenger, TikTok, Telegram, and a web widget
- Can take real actions — booking, payments, human handoff — not just answer questions
- REST API and MCP server support for custom integrations beyond the prebuilt actions
Cons
- Per-message billing makes total monthly cost harder to predict than a flat plan
- Founded in 2025, so there is limited operating history to judge reliability at scale
- Company's headquarters location is not stated on the site
