Five Useful AI Prompts for Virtual Assistants

Email response

Write a professional reply to the email below. Keep the tone friendly and confident. Confirm that I received the request, list the next steps, and avoid making promises that are not included in the original message.

Meeting summary

Turn this transcript into a meeting summary containing the main discussion points, decisions, action items, task owners, deadlines, and unanswered questions.

Standard operating procedure

Convert these notes into a step-by-step standard operating procedure. Include the purpose, required tools, detailed instructions, quality-control checklist, and common mistakes.

Research assignment

Research this topic using recent and trustworthy sources. Separate confirmed facts from opinions, include publication dates, and provide a link supporting every major claim.

Weekly client report

Create a concise weekly client report from these task notes. Organize it into completed work, current work, results, problems, and priorities for next week.

Important AI Safety Practices

AI tools can increase productivity, but virtual assistants remain responsible for the final result.

Protect confidential information

Do not upload passwords, financial records, medical details, customer databases, private contracts, or other sensitive information unless the client has approved the tool and its data policies.

Verify important information

AI can generate inaccurate names, dates, statistics, links, or explanations. Check important claims against reliable original sources.

Obtain meeting consent

Before recording or transcribing a conversation, tell the participants and follow the recording laws that apply to their locations.

Review messages before sending

Use AI to create drafts, but review customer emails, financial communication, legal messages, and public content before publishing or sending them.

Add approval steps to automations

An automation that creates a draft is usually safer than one that automatically sends or deletes information. Add human approval before sensitive actions.

Maintain the client’s voice

Give the AI examples of the client’s preferred tone, terminology, and formatting. Edit the result so it sounds consistent with the client’s brand.
