MonoChat vs SleekFlow
If you would rather pay by agents and channels than by active contacts, or want AI agents that run on your own LLM keys, MonoChat is worth comparing with SleekFlow — here is an honest side-by-side.
SleekFlow is an omnichannel platform priced by Monthly Active Contacts, with a broad channel list, an Automation Flow Builder and AgentFlow AI agents. MonoChat covers the major messaging channels — including WhatsApp coexistence, calls and Flows — and prices by plan, agents and channels, with AI agents that run on the LLM provider you choose.

Where MonoChat Stands Out
What teams usually gain when they move to MonoChat
Your LLM, No Markup
Connect OpenAI, Anthropic, Gemini, OpenRouter, DeepSeek or Ollama with your own key. MonoChat adds no markup to AI usage.
Pricing That Ignores Contact Count
Plans scale by agents and channels, not by active contacts. Incoming messages are never counted.
Custom Functions and MCP
Let AI agents and flows call your own APIs, connect MCP servers, and embed custom views for your team.
Free Plan to Start
Run a real channel on the free plan with 1,000 outgoing messages a month, then upgrade when your team grows.
When SleekFlow Is the Better Choice
MonoChat is not the right fit for everyone. SleekFlow may suit you better if:
- You need channels MonoChat does not list today, such as WeChat, LINE, Viber, or Gmail and Outlook inboxes.
- You want 10 user accounts included from the entry plan and prefer pricing tied to active contacts rather than seats.
- You need a native Salesforce integration, PII data masking or multiple workspaces, which SleekFlow offers on its Enterprise plan.
- You would rather use a fully managed AI agent (AgentFlow) than choose and pay for your own LLM provider.
How to Switch from SleekFlow to MonoChat
A typical migration in four steps
- 1
Move your WhatsApp number
Your WhatsApp Business API number is registered with Meta, not locked to SleekFlow. Disconnect it from SleekFlow and connect it to MonoChat through Meta’s onboarding flow, and plan a short window without campaigns while the switch completes.
- 2
Bring over your message templates
Export the text of your approved templates. Depending on how the number moves, templates either stay with your WhatsApp Business Account or need to be resubmitted to Meta for approval from MonoChat.
- 3
Import your contacts
Export your contacts from SleekFlow as a CSV with labels, custom fields and opt-in status, then import them into MonoChat.
- 4
Rebuild flows and your AI agent
Recreate your automation flows in MonoChat’s workflow builder, upload your knowledge base documents, connect your AI provider key, and test everything before going live.
