Five Adjustment Styles Tailored to Your Needs and Preferences

To resolve common dilemmas—such as "the summary is too clean, losing the subtle nuances and discussion process of the meeting" or "verbatim text is too long and hard to read"—we have implemented a 5-style selection feature that allows you to adjust the balance of the output.

• Verbatim (0) / Summarized (100): Best when you want to capture only the action items and conclusions in the most compact format possible.
• Verbatim (25) / Summarized (75): Useful when you want a summary-based output but still want to retain a slight flow of the critical remarks.
• Verbatim (50) / Summarized (50): Perfectly balances readability with the visualization of the discussion process, split right down the middle.
• Verbatim (75) / Summarized (25) [Recommended]: Firmly preserves the realistic flow and nuances of the conversation while cleaning up redundant phrasing and filler words. This is the most optimal balance for internal sharing, ensuring it remains clear who said what and with what intent when reviewed later.
• Verbatim (100) / Summarized (0): Designed for audits or official records that require a detailed log, or when you want to preserve virtually the entire meeting as an exact record.
