To use ChatGPT for writing PRDs (Product Requirement Documents), Tal outlines the following steps:

1. Dictate the Project Details: Tal starts by dictating the project details and features as if he were conducting a project kickoff meeting. This initial step involves speaking naturally and covering all aspects of the project. He mentions that this can be done using a transcription tool like OpenAI's Whisper, integrated into ChatGPT's app. 00:16:41 - 00:16:48

2. Transcribe the Kickoff: The dictated kickoff meeting is recorded and transcribed. Tal uses a tool like Whisper for this purpose, which is an open-source speech-to-text system provided by OpenAI. 00:21:00 - 00:21:07

3. Input Transcript into ChatGPT: After obtaining the transcription, Tal copies and pastes the transcript into ChatGPT. This step involves experimenting and tweaking the input to optimize the output. 00:21:07 - 00:21:13

4. Provide a Template: Tal's team leads provide a template for how they want the user stories written. This template is included in the transcript or provided separately to ChatGPT to ensure the output aligns with the desired format. 00:22:01 - 00:22:06

5. Prompt ChatGPT: Tal opens a new thread in ChatGPT and provides context by stating the role ChatGPT should assume (e.g., expert product manager) and includes the template for user stories. 00:22:22 - 00:22:29

6. Generate and Edit Output: ChatGPT generates detailed user stories and other components of the PRD based on the provided transcript and template. Tal then reviews and makes necessary edits to finalize the document. 00:16:48 - 00:16:59

These steps help streamline the process of creating comprehensive and detailed PRDs using ChatGPT.
