47 actions, nobody awake
What an AI assistant handled on its own overnight, with nobody working.
Do any of these sound familiar?
- Customer messages arrive overnight and only get answered the next day.
- Your team answers the same question dozens of times a day.
- Customers book and never show up — and you only find out at the time.
- You type the same information into two different systems.
- Closing the weekly report eats a whole afternoon.
- Good people on your team are doing work a system could do.
What Etter builds
Six services. The rule is the same for all of them: only automate what repeats and follows clear logic. Everything else stays with people.
AI agents for customer service
An assistant that answers on WhatsApp instantly, any day and any hour. It handles questions, books appointments and calls you in when the customer needs a person.
- Instant answers with the context of the whole conversation
- Official integration with WhatsApp Business API, Instagram and your site
- Automatic booking in the calendar you already use
- Lead qualification before it reaches your sales team
Custom applications
An application built around the way you work, for when no ready-made system fits.
Sales automation
Answers new enquiries immediately, sends the quote and keeps following up — without anyone having to remember.
Training and nutrition AI
Builds workouts and meal plans following your method, tracks the client and alerts you when something looks off.
Automated reporting
Pulls the numbers scattered across your systems and sends the finished summary every week, by WhatsApp or email.
Systems integration
Makes the programs you already use talk to each other, so nobody types the same thing twice.

What does Etter do?
Etter builds AI automation for Brazilian companies: AI agents for WhatsApp customer service, custom applications and platforms, automated dashboards and reports, systems integration and sales automation. Work is remote, across Brazil.
How much does Etter charge?
An AI customer service agent costs on average R$1,000 per month. The customer service platform with CRM is R$600 per month. Custom development — applications, dashboards and platforms — is quoted per project, with scope and timeline fixed before work starts.
What kind of company does Etter work with?
Small and medium companies and independent professionals with a running operation: clinics, nutritionists, personal trainers, barbershops and salons, online stores and consultancies. The criterion is not size, it is having a repetitive process with enough volume to automate.
How long until the solution is live?
A customer service agent takes two to four weeks. Custom applications take six to twelve weeks to a first production version, with navigable partial deliveries from the early weeks.
Is my company data safe?
Yes. Source code and database belong to the client, with no platform lock-in. When a project requires it, the system runs on dedicated infrastructure without passing through third-party clouds.
