The results you get

What your AI delivers

The AI handles the data retrieval so you can focus on your logistics.

QUOTES

Instant price comparisons

The AI pulls current rates for different service levels. You get a clear breakdown of what each shipping method costs.

TIMELINES

The tool calculates how long a package will take to arrive. You'll see the expected window for both PAC and SEDEX.

The workflow

What your AI does when you ask for a quote.

The AI acts as a bridge between your chat window and the Correios database.

  1. Gather package details

    Your AI identifies if you've provided the weight, dimensions, and zip codes. If something is missing, it asks you for those specific numbers.

FAQ

Common questions

  • 01

    Can the AI buy the shipping label for me?

    No. The AI only retrieves pricing and delivery estimates. You must complete the actual purchase on the Correios website.

  • 02

    Does the AI track my existing packages?

    No. This specific tool is designed for calculating new shipping costs and deadlines, not for tracking active shipments.

  • 03

    Do I need to provide the weight in grams or kilograms?

    The AI will handle the conversion, but it's best to be clear in your prompt to ensure the calculation is accurate.

  • 04

    Can I get quotes for international shipping?

    No. This tool is limited to domestic Correios services within Brazil.

  • 05

    Will the AI remember my frequent shipping routes?

    The AI can remember them within a single conversation session, but it doesn't store a permanent database of your routes unless you provide them again.
