From this input to this video
A script based on NIST’s published guidance becomes a whiteboard training video with captions.
Prompt
Create a 45-second animated cybersecurity training video that teaches recognizing and reporting phishing using NIST’s small-business guidance at https://www.nist.gov/itl/smallbusinesscyber/guidance-topic/phishing to small-business employees. Use my script verbatim for the voiceover — do not rewrite it: An urgent message can make a risky click feel necessary. Phishing impersonates a trusted sender to steal information or deliver harmful software. Pause when a message asks for a password, a payment, a download or immediate action. Check the sender, and verify the request through a contact method you already trust. Do not use the message’s own link or phone number to verify it. Report suspicious messages using your organization’s process. If you already clicked, tell your security contact promptly. Pause, verify and report. Read NIST’s phishing guidance and learn your team’s reporting process. Explain the idea with the warning signs and verification steps in the NIST guidance and reinforce each key term with clear on-screen labels. Visual style: whiteboard. Tone: calm and practical. Open with a short real-world hook, walk through the concept step by step, then close on a one-line recap and this call to action: Read NIST’s phishing guidance and learn your team’s reporting process. Add captions for muted playback.
