The short version

Pick SleekFlow if you're a brand selling and supporting across WhatsApp, Instagram and your website, with AI agents tied to Shopify. Pick ActivityTracker if you sell one-to-one from your own number and want each chat, follow-up and meeting on the client's record.

Who should pick which

Stay with SleekFlow if

  • your customers reach you on WhatsApp, Instagram and website chat, and you want one inbox for all three
  • you sell through Shopify and want AI agents to recommend products
  • you want the official WhatsApp Business API from a Business Solution Provider

Pick ActivityTracker if

  • you sell one-to-one, and clients message your own WhatsApp number
  • you'd rather pay per person than by monthly active contacts
  • you want an agent that answers as you and books the meeting on your calendar

Where SleekFlow is strong

SleekFlow is an official WhatsApp Business Solution Provider built for brands with a lot of conversations. It puts WhatsApp, Instagram and website chat in one inbox, runs AI agents that recommend products through Shopify, and adds HubSpot, Zoho and Salesforce sync on the higher plans. A one-way broadcast nobody replies to doesn't count toward your bill. It prints its prices, has an office in Singapore, and says 7,000+ businesses in 70 countries use it. If you're a retail or service brand selling across channels, SleekFlow fits.

The three differences that matter

Nothing to set up with Meta first

You scan one code on your phone and the WhatsApp you already use is connected, the way WhatsApp Web works. No API number to host. No templates to get approved. Your phone carries on as before.

Priced per person, not per contact you talk to

SleekFlow's bill starts from the number of contacts you chat with each month, and adds 100 at a time when you go over. ActivityTracker is priced per person, so a busy month with your client list costs the same as a quiet one.

Built for the one-to-one sale

A new enquiry becomes a contact with the chat attached, today's follow-ups sit at the top, and clients you haven't spoken to in 30 days come up before they go cold. Your AI agent writes in the first person, as you, and hands you the chat when a person should take it.

Switching in three steps

  1. Scan the code under Linked devices to connect your number. Months of past chats come across with it.
  2. Upload your client spreadsheet, and one tap undoes it if anything looks wrong.
  3. Give your AI agent your website, your brochures and a few lines about you, then try it on yourself before a client sees it.
