A Respond.io alternative when you want the agent, not the inbox
Respond.io is a strong omnichannel inbox for teams of human agents, with AI agents on its higher plans. ROSA starts from the other end: one AI agent does the selling, and a human steps in only when it matters.

Why MAC pricing surprises growing teams
Monthly Active Contacts count everyone who messaged or was messaged in the month. A busy month of enquiries, or a campaign that gets replies, pushes you into the next block of contacts whether those people bought or not. ROSA counts conversations, and six messages or sixty in the same day still count once.
When Respond.io is the better choice
If you run a contact centre with many human agents, need SMS and Messenger alongside WhatsApp, and want deep routing rules for people, Respond.io is built for exactly that.
When ROSA fits better
- You are a team of one to fifty and nobody has time to answer every message.
- You want leads qualified, quoted and booked before a human ever opens the chat.
- You sell in Arabic and English across the Gulf.
- You need the option to run everything on-prem later.
