Chat assistants · alternatives
Ninjō AI starts at $149 per month on Self-Serve, with no free plan, only a 7-day trial. On top of the base you pay $0.035 per message sent, so heavy DM traffic raises the bill, and white-label pricing for agencies needs a sales call. It is also aimed at agency and creator sales, so it is less useful outside that use.
The alternatives in our catalog are general tools you assemble yourself rather than ready-made DM agents. ChatGPT has a free tier and Plus is $20 per user per month, good for drafting replies. Zapier connects 9,000+ apps; its Professional tier is $19.99 per month for 750 tasks and a free plan exists. Make is a visual automation builder with a free plan and Core at $9 per month for 10k credits. n8n suits technical teams, runs cloud-hosted or self-hosted and has a free option, though its starting price is not stated in our data.
"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.
Taken from the documented limitations in our Ninjō AI profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Ninjō AI (this page) | From $149/mo (Self-Serve) | No | Web | There is no free plan, and per-message fees add variable cost on top of the $149 base. |
| ChatGPT | $20/mo (Plus (consumer)) | Yes | Web, Desktop, Mobile, API | Almost every tool (uploads, images, voice, deep research, Codex) has plan-dependent usage caps that OpenAI states can change over time, and the API is billed separately from every ChatGPT subscription. |
| Zapier | $19.99/mo (Professional) | Yes | Web, API | Free plan limited to two-step Zaps and 100 tasks per month; AI agents and chatbots require separate purchases. |
| Make | $9/mo (Core) | Yes | Web, API | Every module action consumes a credit, so complex scenarios use credits quickly |
| n8n | Not published | Yes | Web, API | Cloud plans capped by monthly executions (e.g. 2.5K on Starter); Business plan self-hosted only. |
