How to Turn Rambling Voice Memos Into Clear To-Do Lists with ChatGPT

Small but significant tasks tend to hit me not when I’m focused on my daily list, but during other moments—such as when I’m out walking, commuting, or engaged in activities that leave my mind free to wander.

One habit that highly organized individuals often adopt (though I haven’t perfected it myself) is to open a voice memo app and just speak their thoughts. This is often when some of their best ideas emerge, especially concerning daily errands. The problem is, sifting through a stream of incoherent chatter can be tedious.

Enter ChatGPT, or similar AI options like Claude or Gemini. These AI chatbots excel at processing large amounts of data—be it extensive error reports or random thoughts from a stroll—and discerning patterns or extracting useful information from the chaos.

While you could use voice features directly within ChatGPT, Claude, or Gemini to speak about your tasks, these modes often become overly conversational—interrupting your flow with unnecessary praise (“That’s insightful, Ben!”) or redundant questions (“Want me to find reviews for that plumber?”).

A more effective way is to record your thoughts using a standard voice memos app—such as Apple Notes or Google Recorder for Android—and then provide a transcription to your favorite AI chatbot. You’ll need a tailored prompt that guides the AI to: a) organize your spoken thoughts into a clear to-do list, and b) extract only the relevant tasks or ideas without any extraneous input.

This approach is versatile, compatible with any AI—even free-tier accounts—and doesn’t require voice-enabled features from the AI itself.

Here’s a sample prompt, adapted from various online sources:

Take my voice note as a raw, unedited stream of consciousness. Do not clean, rewrite, or improve the content. Instead, please:

1. Identify all specific tasks or next steps I mentioned.

2. Highlight any decisions I need to make.

3. List any ideas I said I wanted to revisit later or think about.

Only analyze what I explicitly said. Do not add suggestions or invent new details.

Using this prompt with a simple transcription—such as from Apple Notes—I just spoke freely about possible tasks, from immediate priorities (“I need to write the weekly prompt”) to later considerations (“Make sure to refill the pepper because it’s running low”).

After recording, I fed the transcription into ChatGPT (using the GPT-5.5 Instant model), and within seconds, I received an organized to-do list:

Here’s a categorized summary of what I mentioned:

1. Immediate Tasks / Next Steps

• Write the weekly prompt.
• Choose a topic for the newsletter.
• Call the dermatologist about a bill payment.
• Quickly review your bank accounts.
• Decide on dinner based on the weekly meal list.
• Charge your Sonicare toothbrush.
• Start packing for your trip to New Jersey this weekend.
• Refill the pepper supply—it’s running out.
• Clean the robot vacuum tanks.
• Finish laundry.
• Review the BenBot issue for follow-up.

2. Decisions to Make

• Choose what to cook for dinner tonight.
• Determine if the BenBot issue needs further action.

Overall, not too shabby. A suggestion: place the newsletter topic decision in the “decisions” section (a minor tweak in the prompt can achieve this). Feel free to experiment with the prompt, especially during brainstorming sessions. For added efficiency, consider linking your to-dos directly to project management tools like Notion or other online workspaces.
