Live demos. Real systems.
Try them now.
These aren’t mockups. Each demo is wired to the same stack we deploy for clients — FreeSWITCH for voice, Supabase + pgvector for retrieval, Claude for reasoning. Pick one and try it.
Call a real AI receptionist and talk to it yourself.
Tell us who you are and we’ll reveal our live demo line. Call it from any phone and you’re talking to an OpenAI Realtime agent running on our FreeSWITCH stack — prompted as a small-business receptionist. Ask it anything. Hang up when you’ve heard enough.

For your business: same agent answers your inbound line 24/7, qualifies callers, books appointments on your calendar, and emails the transcript. See the AI Receptionist service →
Submit a lead — or click a sample tag — and the agent’s reasoning, extracted fields, and downstream notifications will appear here in real time.
Submit a fake lead. Watch the agent route it.
The most boring AI use case is also the highest ROI: a form gets filled, an agent reads it, summarizes it, pulls out the qualifying signal, and notifies the owner. This live demo posts to Discord and email — production deployments swap in Slack, GoHighLevel, or your CRM.

For your business: stop reading every contact-form submission. Get only the ones that matter, with the answer already drafted.
Ask questions of a real document. Get cited answers.
We pre-loaded a sample knowledge base. Ask anything from it. The agent retrieves the relevant chunks, cites them, and refuses to answer when the source doesn’t support it — the part most consumer chatbots skip.

For your business: point the same pipeline at your SOPs, contracts, or product docs. Your team asks; it answers — with receipts.
Ask anything about Stack Consulting’s services. Answers cite the chunk they came from. If the corpus doesn’t cover it, the agent says so.
Hear the receptionist built for your trade.
These call the same FreeSWITCH + OpenAI Realtime stack as the demo above — but each one is scripted for a specific industry: emergency triage, the right intake questions, and a calendar that books around existing jobs. Pick your trade, verify your number, and call it.
