Search with AI requires an account and an AI budget. Katana turns your words into quantitative and qualitative conditions, then AI reads annual reports to judge the candidates. Check your remaining AI budget after signing in.
When your AI budget is used up, AI features pause until more budget is available.
Use Katana from your own AI.
Connect Katana to Claude, ChatGPT, or another AI assistant, and it uses Katana's financial data and annual reports to go from picking stocks to analysis. Free with registration.
Tool calls are limited to 50 per day (Japan time), or 500 on a paid plan. Qualitative judgment uses the same AI budget as Search with AI.
