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
-
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.
-
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.
-
Import your contacts
Export your contacts from SleekFlow as a CSV with labels, custom fields and opt-in status, then import them into MonoChat.
-
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.
FAQ
MonoChat vs SleekFlow: FAQ
Common questions from teams comparing the two platforms
Is MonoChat a good SleekFlow alternative?
It can be, especially if you want pricing based on agents and channels instead of active contacts, or AI agents that run on your own LLM keys. MonoChat brings WhatsApp, Instagram, Facebook, TikTok, Telegram, web chat, SMS and voice into one team inbox. If you rely on WeChat, LINE or email inboxes, SleekFlow may fit better.
Can I keep my WhatsApp number when switching from SleekFlow?
Yes. The number belongs to your business and is registered with Meta. You disconnect it from SleekFlow and connect it to MonoChat through Meta’s onboarding. Export any chat history you want to keep before you switch.
How is MonoChat pricing different from SleekFlow’s MAC model?
SleekFlow prices its plans by Monthly Active Contacts (MAC), with WhatsApp conversation fees and a number hosting fee charged separately. MonoChat prices by plan, agents and channels: a free plan, a Growth plan at $120/month with 2 agents, 1 channel and 100,000 outgoing messages included ($30 per extra agent or channel), and custom Enterprise pricing. Contacts are not counted, and Meta’s WhatsApp fees apply separately.
Does MonoChat have a free plan?
Yes. The Basic plan is free forever with 1 user, 1 channel and 1,000 outgoing messages per month. Incoming messages are always free, and the plan includes custom flows, custom views and AI-powered conversations.
Which AI models can I use in MonoChat?
You can bring your own key for OpenAI, Anthropic, Gemini, OpenRouter, DeepSeek, Ollama and other providers, with no markup from MonoChat — or use MonoChat’s AI APIs, billed by token usage.
Does MonoChat support WeChat, LINE or Viber?
MonoChat’s channels are WhatsApp, Instagram, Facebook, TikTok, Telegram, web chat, SMS via Twilio and voice over SIP. If WeChat, LINE or Viber are core to your business, SleekFlow may be the better fit today.
