Live demos

Try it before you talk to anyone

Most software companies show you a video. Every product below is the real application, running on seeded sample data. Take the credentials, sign in, and open every screen.

These are sandboxes. They hold invented sample data, never real customer records, and they run in mock mode — no live calls, texts or posts leave the demo. Break whatever you like.

Appointment Reminders

Coming soon

Reminders that text and call your clients before every appointment, so they confirm, reschedule or cancel themselves — and your front desk stops chasing people.

  • Fastify
  • React 19
  • Prisma
  • PostgreSQL
  • BullMQ
  • Redis
Full application

Two seeded companies with realistic appointment history, in full mock mode. Deploying now — credentials appear here the moment it is up.

Worth trying

  • Upload the sample spreadsheet — 25 rows with a bad phone number, a missing time and a duplicate — and watch the mapping wizard catch each one
  • Open Settings → Reminder rules: a 48-hour call, a 24-hour text, a 2-hour call, each with allowed hours and retry counts
  • Send the text reminder, then reply CONFIRM — or write a real sentence like "I can't make it, can I come Friday afternoon?"
  • Reschedule from the text and watch it offer genuine open slots, move the booking and recalculate every remaining reminder
  • Find the seeded client Test Failure to see a carrier rejection retry, then fail permanently
  • Switch to the second company and confirm the first company's appointment URL returns Not found
About Appointment Reminders

AI Voice Agent

Coming soon

The reminder call, answered like a person. A natural ElevenLabs voice makes the call, the client simply says "I need to reschedule", and the agent offers real open times and moves the booking.

  • ElevenLabs
  • Twilio Voice
  • Answering-machine detection
  • Fastify
  • PostgreSQL
Full application

Lives inside the same platform as Appointment Reminders — one login opens both. Deploying now.

Worth trying

  • Open Settings → Voice, preview the available voices and pick the one that speaks to your clients
  • Use "Write it for me" for three AI-written call scripts, then edit the wording per rule
  • Press Reschedule on the 48-hour call and read the transcript: the script, the client asking to move, real availability, the confirmation
  • Watch answering-machine detection turn a voicemail into a spoken message and trigger the text fallback
  • Note that every speech failure falls back to the carrier voice — a synthesis outage can never stop a call going out

AI Receptionist

Coming soon

Inbound calls answered 24/7 on your existing number — booking, IVR menus, insurance capture, and escalation to a human when it matters.

  • NestJS
  • Next.js
  • PostgreSQL
  • Twilio
  • Streaming STT
  • Pluggable TTS
Full application

The full tenant dashboard needs a live phone number, so this one stays a chat demo plus a guided walkthrough for now.

Talk to the receptionist

Chat with the agent for a sample dental clinic. No login needed.

Worth trying

  • Book an appointment, then ask to move it
  • Ask about hours, pricing and directions
  • Ask something it should refuse, and watch it escalate to a human
  • Switch to Bangla mid-conversation

Simplex ERP

Coming soon

Accounting, inventory, sales, HR and payroll built around a conversational assistant instead of buried menus.

  • Next.js
  • Prisma
  • PostgreSQL
  • tRPC
Full application

Full ERP with seeded company data — ledger, stock, invoices, payroll runs — deploying shortly.

Ask the assistant

Query a sample company's live data and watch it take actions.

Worth trying

  • Ask "how is revenue this month?" and check the number against the ledger
  • Say "create an invoice for Acme Corp: 5x Widget A" and open the invoice it made
  • Ask which items are low on stock, then place a reorder
  • Run a payroll cycle and inspect the generated entries

A voice-first PWA tutor for Bengali speakers — real spoken conversation, corrections on the sentence you actually said.

  • Next.js
  • TypeScript
  • Streaming STT/TTS
  • PWA
Full application

Installable PWA with the full learning-intelligence layer and progress tracking — deploying shortly.

GrowthAgent

Coming soon

An AI marketing employee: one business goal in, and it produces the strategy, the assets and the imagery — then measures what worked.

  • Next.js
  • Prisma
  • PostgreSQL
  • Meta Graph API
Full application

Full dashboard with a seeded campaign, the approvals queue and attribution reporting — deploying shortly.

Worth trying

  • Set a business goal and let it generate a campaign end to end
  • Open the approvals queue — nothing publishes until you say yes
  • Try to publish a campaign that is not approved, and watch it be refused
  • Follow a booking back to the campaign that earned it
