Persistent memory
Workers get more effective over time. Memory is a pluggable interface — areev by default, or bring your own.
Voice-native AI workers
Build AI workers that get work done.
VAAIS is the platform for building persistent voice-native workers — they talk to your customers, operate your systems, and work toward outcomes. Not just another call bot.

Agent vs. Worker The agent handles the call.
The agent handles the call.
The worker owns the result.
Traditional voice agent A conversation that ends
- Receives the call
- Processes the request
- Ends the call
- Forgets everything
Voice-native worker A system that continues
- Remembers every past interaction
- Operates your business systems
- Tracks goals and follows up
- Owns the outcome over time
Why VAAIS
Five things that make a worker, a worker.
Voice native
Answer, make and transfer calls over telephony and the browser. Voice is a first-class capability, not an add-on.
A builder you don't outgrow
Design playbooks visually, then extend with code. The visual builder is the beginning, not the ceiling.
One worker, every channel
The worker stays the same — only the channel changes. One worker, one memory, one set of objectives.
Open and self-owned
Your workers belong to you, not to a vendor. Run VAAIS on your own infrastructure with your own keys.
Worker templates
Start with a worker. Make it yours.
Each template is a worker, not a script — ready to staff your front line and grow with you.
Reception
Answers, routes, books appointments and handles FAQs — with context.
Sales
Qualifies leads, makes outbound calls and books meetings.
Recruiting
Screens candidates, schedules interviews and tracks history.
Collections
Calls overdue accounts, negotiates plans and records commitments.
Customer Success
Runs check-ins, handles renewals and flags risk early.
How it works
Build visually. Extend with code. Deploy anywhere.
01
Design the playbook
Drag nodes into a flow — greet, ask, branch, call a tool, transfer, end. The procedure your worker runs, built visually.
02
Wire in your systems
Workers operate your systems via HTTP and MCP tools. Add knowledge, pick models and voices, bring your own keys.
03
Deploy on your infra
Run the worker over telephony or the browser, on your own infrastructure. Scheduled outbound calling included.
