About this app

AI money
Discover the power of Artificial Intelligence to enhance your results.

Search and analyze market data in seconds. Your AI virtual assistant can monitor important information for your strategy and diagnose risk factors in your portfolio.

Money IR
Never worry about IR from your operations on the Stock Exchange again.

For determining, calculating and paying monthly income tax

1. Grana integrates your data directly from B3 and calculates whether you have income tax to pay in the month.
2. If you have one, you pay the IR through the app itself, using a bank slip, Pix or credit card.
3. Done! You receive proof of payment by email.

The application calculates loss compensation and legal exemptions. There is no need to issue DARF, import brokerage notes or enter any transaction for the month.

IR Optimizer

Save thousands of reais and never pay taxes unnecessarily again.

The Optimizer actively monitors and notifies the investor throughout the month about their exemption limit. If the investor has IR to pay, the Optimizer informs how much IR can be saved through Loss Compensation and which positions best fit this strategy.

App yem potencial, mas peca ao nao dar suporte a alguns tipos de operacao ( opção flexível no meu caso) e isso bagunça todo o calculo se imposto a pagar porque o prejuizo acumulado simplesmente nao pode ser cadastrado. Solução dada pelo suporte: controlar na mão. Entao pra que preciso do app? Fiz versao paga anual e me arrependo amargamente. Se a diretoria da empresa quiser me contactar para saber mais, fico a disposicao, pois o suporte do chat nao me deu a mínima. Lamentável.
