Changelog

Recent updates and improvements to WizChat.

March 2026​

2026-03-03​

New Features

  • In-chat data analysis — End users can upload Excel and CSV files directly in the chat for instant analysis. Ask questions in natural language and get answers with interactive charts and tables.
  • Knowledge Scopes — Partition your knowledge base into named scopes with independent access control, behavior overrides, MCP server filtering, and budget caps (Business & Enterprise).
  • Per-plan data retention — Chat history, Q&A logs, and in-chat file uploads are now retained based on your subscription plan, from 30 days (Free) to unlimited (Enterprise).
  • Per-scope cost limits — Set monthly or weekly budget caps on individual knowledge scopes to control spending.

Improvements

  • Smarter sheet selection for multi-sheet Excel workbooks — the AI automatically picks the most relevant sheet based on your question.
  • Follow-up questions remember context (selected sheet, metrics) across the conversation, so you don't need to repeat details.
  • Automatic chart type selection based on question intent — trend questions get line charts, comparisons get bar charts.
  • Web search is automatically disabled when querying internal data (spreadsheets, databases) to avoid irrelevant external results.
