User Guide

A friendly, step-by-step walkthrough of UltraVoice — written for everyone, no technical background needed. We'll go one screen at a time: creating an account, building your first AI voice agent, giving it knowledge, testing it live, and watching it work.

New here? A great first goal: create an agent, write a clear system prompt, open Voice Test, and have a real conversation with it. You can be there in about 20 minutes — and new accounts start with $10 of free credit.

What is UltraVoice?

UltraVoice lets you create AI agents that talk to people over the phone or web — answering calls, qualifying leads, booking appointments, and answering questions in a natural, human-sounding voice. You describe what the agent should do; UltraVoice handles the listening, thinking, and speaking.

• Agents — your AI callers. Each has a personality, a voice, and a job.
• Live calls — talk to your agent in the browser or over a real phone number.
• Knowledge — feed it documents and rules so it answers accurately.
• Analytics — review every call, transcript, and quality score.

Heads up: Throughout the app you'll see a yellow banner reading "This platform is for internal testing purpose." That's expected during the beta — it doesn't affect anything you do.

1 · Create your account

Everything starts with a free account. New accounts get $10 of free credit, enough for plenty of test calls.

1. Click Get started free on the home page.
2. Enter your first and last name, a work email, and a password (at least 8 characters).
3. Press Create account. We'll email you a short verification code.
4. Type the code on the next screen to confirm your email — and you're in.

Already have an account? Use the Sign in link at the bottom of the form instead.

2 · Sign in

Returning users land here. Enter your email and password to open your workspace.

1. Enter the email and password you signed up with.
2. Forgot your password? Click Forgot password? to reset it by email.
3. Press Sign in — you'll arrive at your dashboard.

3 · The dashboard

Your home base. At a glance you can see how many agents you have, how many conversations have happened, and jump straight into common tasks.

What you're looking at

• Top cards — total agents, total conversations, platform status, and your plan.
• Agents list — every agent in this workspace with its status and call count. Click one to open it.
• Quick Actions (right) — shortcuts to create an agent, open the voice tester, manage knowledge, or connect integrations.
• Recent Calls — the latest conversations, so you can review what just happened.

The left sidebar is your main menu and stays with you everywhere. It's grouped into Build, Test, and Monitor. Click the UltraVoice logo any time to return to the public home page.

4 · Your agents

The Agents page lists every voice agent you've built. Think of each agent as one "employee" with a specific role — a support rep, a scheduler, a salesperson.

• Click any agent card to open and edit it.
• Use + New (or the Create button) to build a new one.
• The Active badge means the agent is ready to take calls.

5 · Create an agent

This is where the magic starts. You give your agent a name, tell it who it is and how to behave, and choose how it greets people.

1. Agent Name — something memorable, e.g. "Front-desk Booking Bot".
2. Description — a short note for your own reference.
3. System Prompt — the most important field. Describe who the agent is and how it should act, in plain English. For example: "You are Aria, a friendly dental receptionist. Help callers book, reschedule, or cancel appointments. Always confirm the date and time before finishing."
4. Welcome Message — the first thing the agent says when a call connects.
5. Pick a Language and Connection Type (leave the defaults if unsure), then Create.

Tip: Write the system prompt the way you'd brief a new hire — who they are, what they should do, what to avoid, and the tone to use. The clearer you are, the better the agent behaves.

6 · Configure your agent

After creating an agent you land on its configuration page. The tabs across the top let you fine-tune everything about it.

The tabs

• Configuration — name, system prompt, welcome message, language, and other basics.
• Providers — choose the voice (text-to-speech), the listening engine (speech-to-text), and the AI brain (LLM). Sensible defaults are pre-selected.
• Tools — actions the agent can take (see section 8).
• Knowledge Base — attach documents the agent can reference (see section 9).
• Handbook — house rules that always apply (see section 10).
• Telephony — connect a phone number for real calls.
• Flow Builder — design a step-by-step conversation (see section 7).

The green "Live · Up to date" banner means your changes are published and calls are using the latest version. UltraVoice keeps a version history, so you can always roll back.

7 · Flow Builder (optional, more control)

Most agents work great with just a system prompt. But when you need a call to follow exact steps — like collecting specific information in order — the Flow Builder lets you draw the conversation as a diagram.

How it works

• Drag blocks from the left palette onto the canvas and connect them in order.
• Welcome — the opening line. Conversation — free-form chat. Question / Decision — branch based on the answer. Tool Call — do something (look up data, book a slot). Transfer / End — hand off to a human or hang up.
• Your work saves automatically (see the "Saved" indicator).

Important: A flow only goes live when you turn it on. Use the Mode toggle (or "Activate Flow Mode") to switch the agent from its single prompt to the flow. Building or saving a flow never activates it on its own — so you can design freely and flip the switch only when you're ready.

8 · Tools & actions

Tools let your agent do things during a call — look up an order, check a calendar, send a confirmation — instead of only talking. Every agent also gets a built-in End Call tool so it can hang up gracefully.

• Add a tool, give it a clear name and description, and the agent will use it when it makes sense in conversation.
• Tools can connect to your own systems through the Integrations area (section 11).

9 · Knowledge Base

Give your agent the facts it needs. Upload documents — price lists, FAQs, policies — and the agent can pull accurate answers from them during a call instead of guessing.

1. Create a knowledge base and add your content (documents or text).
2. Open an agent → Knowledge Base tab → attach it.
3. The agent now answers from your material — and stays accurate.

10 · Handbook

The Handbook holds house rules that apply to every interaction — things like compliance lines, tone of voice, or "never quote a price without checking." These rules take priority, so your agents always stay on-brand and on-policy.

Tip: Use the Knowledge Base for facts ("our hours are 9–5") and the Handbook for behaviour ("always greet by name, never argue with a customer").

11 · Integrations

Connect UltraVoice to the tools you already use — your calendar, CRM, or other systems — so agents can read and update real data during a call.

• Browse the available connectors and follow the prompts to link an account.
• Once connected, those actions become available to your agents as tools.

12 · Voice Test — talk to your agent

The fastest way to hear your agent in action. Pick an agent and start a real, live voice conversation right in your browser — no phone needed.

1. Find your agent and click Start Call.
2. Allow microphone access when your browser asks.
3. Speak naturally — the agent listens, thinks, and replies out loud. Watch the live transcript as you talk.
4. Click to end the call when you're done.

Note: Use a headset for the cleanest experience. Each test call uses a small amount of your wallet credit (billed by the second) — see section 17.

13 · Telephony Test — over a real phone

Once you've connected a phone number, you can test your agent on an actual phone call, exactly as your customers will experience it.

• Choose the agent and phone number, then place the test call.
• Great for checking how the agent sounds and behaves over a real line.

14 · Simulation Tests

Want to check your agent against many scenarios without making dozens of calls yourself? Simulation Tests run automated, text-based conversations against your agent and report how it did.

Good to know: Simulations are text-only (no voice), so they're fast and don't use call credit — a cheap way to sanity-check changes before a live test.

15 · Call History

Every conversation across all your agents, in one place. Review what happened, how long it took, and how fast the agent responded.

• Filter by agent, status, or channel (web / telephony), or search for a specific session.
• Click any row to open the full transcript and details of that call.
• The top cards summarise totals: calls, turns, average latency, and total talk time.

16 · Analytics

See trends over time — call volume, durations, and performance — so you can understand how your agents are doing and where to improve.

17 · Billing & wallet

UltraVoice uses a simple prepaid wallet. Calls cost $0.03 per minute, billed by the second. New accounts start with $10 free, and you can top up any time with a card.

What's on this page

• Wallet Balance — how much credit you have left.
• Add Funds — pick an amount (or enter your own) and pay securely with Stripe. A receipt/invoice is generated for every top-up.
• Transactions — a clear line for every charge: which call, how long, and how much it cost — plus your top-ups and free credit.
• Invoices — downloadable invoices for your records.

1. Click an amount under Add Funds (e.g. $25).
2. Press Pay with Stripe and complete the secure checkout.
3. Your balance updates automatically when you return.

Note: Only live voice and telephony calls draw from your wallet. Building agents, editing prompts, and running text simulations are free.

🎉 That's the whole tour. Create an agent, write a clear system prompt, open Voice Test, and have a real conversation with it. From there, add knowledge, connect a phone number, and watch the results in Call History.
