Credit where it's due
Dust is a clean, well-built internal AI assistant and agent builder for teams — a tidy way to put company knowledge and custom agents in front of your people, priced per seat.
Side by side
An internal assistant, or an operator.
An operator with a unified inbox, voice, and approvals — running across the work, not beside it.
An internal assistant and agent builder your team opens to ask and build.
Proposes writes across your connected accounts; a person approves, and every action is logged.
Centered on assistants and agents over your knowledge and tools.
Answers your phone line and website chat; inbound calls land in your thread.
Focused on text-based assistants for internal teams.
Unifies email, chat, and tickets into one thread and acts where the work happens.
Connects to your data sources to answer; not a customer-facing inbox.
Priced on usage — you pay for work done, with daily spend caps. Start free, from $39/mo.
Priced per seat — you pay by headcount.
The verdict
Dust is an internal assistant billed by headcount. Kantum adds a unified multi-channel inbox, voice, and approval-gated actions — and is priced on usage, so you pay for work done, not seats.

When Dust is the right choice
An internal team assistant.
A defined team that each logs in to ask questions and build assistants over company knowledge, where per-seat pricing is predictable and easy to reason about.
When Kantum is the right choice
High autonomous volume, few logins.
Operations with a lot of work and few seats — or customer-facing voice and chat. Usage pricing fits when the value is work done, not the number of people logged in.
