Before any feature works, finish this one time setup.
Leva cerca de três minutos.
Watch my walkthrough of the platform first:
Agora vamos analisar cada etapa.
Passo 1: Crie sua conta
Go to the Synthflow website and click the Get Started button.
Insira seu e-mail profissional e crie uma senha.
✓ Ponto de verificação: a confirmation email lands in your caixa de entrada within a minute.
Passo 2: Conecte um número de telefone
Synthflow AI runs in the browser, so there is no app to download.

Eis como o painel de controle se parece:
✓ Ponto de verificação: your number shows a green connected status.
Step 3: Feed the Agent Your Business Data
Upload PDFs or documents so the agent knows your services, hours, and prices.
No coding skills are needed at any point here.
✅ Concluído: Você está pronto para usar qualquer um dos recursos abaixo.
How to Use Synthflow Smart Call Manager
Gerenciamento inteligente de chamadas lets you route every inbound and outbound call to the right ai agents automatically.
Veja aqui como usá-lo passo a passo.
Step 1: Open the Numbers Tab
Click Phone Numbers, then assign your number to an agent.
One number can hold separate inbound and outbound agents.
Step 2: Set Your Routing Rules
Choose what happens on busy lines and after hours.
Add a transfer number so callers reach a human when needed.
Eis como isso se parece:
✓ Ponto de verificação: the call log shows your test with a full recording.
Step 3: Run a Test Call
Use the dashboard to place a live test call and listen back.
✅ Resultado: no more missed calls, day or night.
💡 Dica profissional: Set a second transfer number for overflow. Sales teams lose deals when the first line rings out.
Como usar o agendador automático do Synthflow

Veja aqui como usá-lo passo a passo.
Passo 1: Conecte seu calendário
Open Integrations and connect Google Calendar or Cal.com.

Step 2: Define Your Availability
Pick your working hours, slot length, and buffer time.
Real time booking then happens mid conversation, not after it.

Step 3: Add a Confirmation Action
Trigger an SMS or email confirmation the moment a slot is taken.
✅ Resultado: your calendar fills while you sleep.
💡 Dica profissional: Block a 15 minute buffer between slots. Back to back bookings leave no room when a call runs long.

Veja aqui como usá-lo passo a passo.
Passo 1: Escolha um modelo
Start from a pre built template such as appointment scheduling.

Step 2: Write the Greeting
Keep the opening line short and name your business.
Tell the agent to acknowledge the reason for the call before answering.
Eis como isso se parece:
✓ Ponto de verificação: an after hours test call gets a full answer, not voicemail.
Step 3: Set an Escalation Path
Route anything the agent cannot answer to a human on request.
✅ Resultado: 24/7 availability without night shift staff.
💡 Dica profissional: Add your top ten questions to the knowledge base. Callers ask the same things far more often than you expect.

Agentes de voz de IA lets you build ai voice agents that hold real conversations with your customers.
Veja aqui como usá-lo passo a passo.
Step 1: Choose Your Build Mode
Pick Flow Designer for structured logic or Single Prompt for speed.
You can create multiple agents using both approaches.
Step 2: Add Conversation Nodes
Each node in Flow Designer is one action or decision point.
Place a Conversation node before any branch so the agent waits for the answer.
Deterministic logic means the agent follows set rules rather than making its own decisions.
Eis como isso se parece:
✓ Ponto de verificação: your agent greets you by name on a test call.
Step 3: Pick the Voice
Escolha um OnzeLabs voice, then tune tone, speed, and volume.
✅ Resultado: an ai voice that most callers cannot tell from a person.
💡 Dica profissional: Upload audio samples to clone your own voice. Regular customers respond better to a voice they already know.

Veja aqui como usá-lo passo a passo.
Step 1: Open Call History

Share the transcript with your team so any fact you added gets checked.
✅ Resultado: a clear view of where the agent loses people.
💡 Dica profissional: Review ten transcripts every Friday. Fifteen minutes of reading beats a month of guessing.
Como usar a integração do Synthflow com o WhatsApp
Integração com o WhatsApp lets you continue the conversation on a channel people actually read.
Veja aqui como usá-lo passo a passo.
Step 1: Link WhatsApp
Connect your business number in the integrations panel.

Step 3: Set the Trigger
Fire the message only on calls that end with a booking or a quote.
✅ Resultado: fewer dropped leads between the call and the sale.
💡 Dica profissional: Keep messages under two lines. Long follow ups get ignored, short ones get replies.
Como usar o Synthflow AI Receptionist
Recepcionista de IA lets you greet callers, qualify them, and escalate the hard ones.
Veja aqui como usá-lo passo a passo.
Step 1: Define the Intake Questions
Ask name, reason for calling, and preferred callback time.

Step 3: Turn On Warm Transfer
The agent passes call context to the human before handing over.
✅ Resultado: your team only picks up calls worth their time.
💡 Dica profissional: Score leads on budget and timeline, not politeness. Friendly callers are not always buyers.

Veja aqui como usá-lo passo a passo.
Step 1: Load Your Service Menu
Upload your list of services, hours, and prices.

💡 Dica profissional: Add an accessibility note to your greeting. Offering a slower pace helps callers who need it.
How to Use Synthflow IVR Optimizer
Otimização de IVR lets you replace press one menus with plain speech.
Veja aqui como usá-lo passo a passo.
Step 1: Map Your Current Menu
Write down every option callers hear today.
Most menus have three real paths and a lot of noise.

Ask callers what they need and let the agent understand the answer.
The Multi-Agent System keeps each path as its own small flow.
Eis como isso se parece:
✓ Ponto de verificação: every spoken request reaches the right agent.
Step 3: Test Every Path
Call in and try each path, including the one nobody uses.
✅ Resultado: shorter calls and fewer hang ups.
💡 Dica profissional: Kill any menu option under two percent of traffic. Fewer choices means faster calls.
Dicas e Atalhos Profissionais do Synthflow
After eight months on this platform, here are the shortcuts I actually use.
Every user gets the same construtor, so these work at any account level.
Atalhos de teclado
| Ação | Atalho |
|---|---|
| Save the current agent | Ctrl + S |
| Duplicate a selected node | Ctrl + D |
| Undo a flow change | Ctrl + Z |
| Fit the whole flow on screen | Shift + 1 |
Características ocultas que a maioria das pessoas não percebe
- Sistema Multiagente: break one huge flow into small reusable sub flows that are easier to work on.
- Personalizado clone de voz: upload audio samples and the tool builds a voice that sounds like your own team.
- Warm transfer context: the human who picks up hears what happened before they say hello.
- BELL framework: build, evaluate, launch, and learn is the loop Synthflow recommends for every agent.
Here is what my own account looks like after eight months of use:
Erros comuns a evitar no Synthflow
Mistake #1: Branching before the agent has an answer
❌ Errado: adding branch logic straight after the greeting node.
✅ Direita: place a Conversation node first so the system waits for and stores the reply.
Mistake #2: Launching with an empty knowledge base
❌ Errado: going live with only a prompt and hoping the agent guesses your prices.
✅ Direita: upload your service documents before the first real call.
Mistake #3: Ignoring accents and complex questions
❌ Errado: assuming the ai handles every caller without help.
✅ Direita: build an escalate path cedo, because heavy accents and complex questions still need a person.
Solução de problemas do Synthflow
Problem: The agent talks over the caller
Causa: the interruption threshold is set too low for your line quality.
Consertar: raise the silence timeout by half a second and test again on a mobile connection.
Problem: Bookings are not reaching the calendar
Causa: the calendar connection expired or the account lost booking permission.
Consertar: disconnect the integration, reconnect it, and place one test call to confirm.
Problem: Your bill jumped this month
Causa: usage based billing scales with call minutes, so volume spikes hit the invoice fast.
Consertar: cap concurrent calls and check the minutes report weekly instead of monthly.
📌 Observação: if none of these fix your issue, contact Synthflow support.
