AI Chat

Kabuken provides two AI features: document summaries on company pages and a persistent chat interface for deeper analysis.

AI document summaries

On the AI Analysis tab of any Company Detail page, Kabuken shows an AI-generated summary of the selected filing. The summary covers key financial highlights and notable disclosures in plain language.

Summaries are available in both English and Japanese based on your language preference.

AI question box

Below the summary on the AI Analysis tab, there is a question input box. Type a question about the company or its filing and press Enter. The AI answers based on the content of the selected document.

Example questions:

• “What was the main driver of revenue growth this year?”
• “How did operating costs change compared to last year?”
• “What risks does the company highlight in this report?”

Tip

Be specific about the metric or topic you want to know about for more precise answers.

Chat page

The Chat page provides a full conversation interface with persistent sessions.

Creating a session

1. Go to Chat in the main navigation
2. Click New Chat
3. Add one or more documents to provide context (optional but recommended)
4. Type your first message and press Enter

Each session is saved automatically. You can return to any previous session and continue the conversation.

Sending messages

Type in the message box at the bottom and press Enter or click Send. The AI responds based on the documents linked to the session and the conversation history.

Rating responses

Each AI response has thumbs-up and thumbs-down buttons. Use these to indicate whether the answer was helpful. Ratings help improve future responses.

Session limits by tier

	Basic (Free)	Investor
Chat sessions per month	3	10
Messages per session	5	30

Once you reach the session or message limit, you will see an upgrade prompt. Previous sessions remain accessible but cannot receive new messages until the next month or until you upgrade.

Caution

Chat session counts reset at the start of each calendar month.

Tips for good answers

• Add the relevant document to the session before asking questions about a specific filing
• Ask one question at a time rather than combining multiple questions into one message
• Reference specific items when possible (e.g., “segment revenue” rather than just “revenue”)
• Ask follow-up questions to dig deeper into a topic — the AI retains context within the session
• For cross-company comparisons, start a new session per company to keep context focused
