Short answer

How can I automate CNAE classification?

Your AI uses the get_cnae_classe tool to pull official IBGE data based on your descriptions. This turns raw text into structured economic codes. You'll see the specific outcomes below.

The results you get

Where your data lands

The AI converts messy text into standardized economic identifiers.

DATA

Standardized CNAE codes

The AI finds the exact code from IBGE. You get a clean identifier for every company you process.

LISTS

Categorized datasets

Your AI maps descriptions to specific sectors. This makes your lists easy to filter and segment.

REPORTS

Sector analysis

Once codes are assigned, your AI can group companies by industry. This shows you market concentration immediately.

HUMAN

Manual review

If a description is too vague, the AI flags it. You decide how to handle ambiguous cases that don't match a clear class.

The workflow

What your AI does when a description arrives.

The AI acts as the bridge between your text and the official IBGE database.

  1. Parse activity

    Your AI reads the company name or activity description to understand the core business function.

    get_cnae_classe

  2. Retrieve code

    The AI calls the official IBGE database to find the matching economic class.

    get_cnae_classe

  3. Verify match

    The AI compares the retrieved code against the original text to ensure the classification is accurate.

    get_cnae_classe

  4. Structure output

    The AI formats the code and sector name into a clean structure for your use.

FAQ

How this task behaves

  • 01

    Can the AI change the official IBGE codes?

    No. The AI only retrieves existing codes from the official database. It cannot create or modify the CNAE structure.

  • 02

    What happens if the business description is too short?

    If the description doesn't provide enough context to find a match, the AI will tell you it can't find a specific class.

  • 03

    Does the AI handle multiple companies at once?

    Yes, if you provide a list or a file, your AI can iterate through them one by one using the tool.

  • 04

    Can the AI update my database directly?

    No. The AI provides the classification data to you. You are responsible for moving that data into your own systems.

  • 05

    Will the AI decide the sector if there are two options?

    The AI will suggest the most likely match, but it is up to you to confirm the classification if the business activity is ambiguous.
