Monster Letter #3: Write a Marketplace listing in two minutes (+ 5 more good things)
Wed, Oct 28, 2026
Hi, AI monsters! Meet an AI with seriously bad fishing luck, then learn how to write a Marketplace listing in two minutes flat. Down below, Gemini can describe the world to people who can't see it well. Scroll on down!
Why was the AI terrible at fishing?
It kept catching bugs! 😂
Selling something on Marketplace or at a garage sale and staring at a blank caption box? Describe the item to ChatGPT, Gemini, Claude or Grok and ask: “Write a friendly Facebook Marketplace listing from this item description. Include: clear title, 2–3 short benefit bullets, condition, size if relevant, a pickup note, and a fair price range. Keep it honest, no hype.” Tweak the price to what you'd actually take, add your photo, and post.
Feeling like you should do everything? Dump everything on your mind into a note for 3 minutes, then paste it into ChatGPT, Gemini, Claude or Grok and ask: “Turn this into: (1) 3 clear priorities for this week, (2) a short ‘nice if I get to it’ list, (3) anything I can delete or postpone without guilt. Be realistic for a normal busy week.” You walk away with a tiny plan instead of that cloudy “I should do everything” feeling.
Staring at a form or agreement and thinking “I should understand this, but I don't”? Black out names, account numbers and addresses first, then paste the confusing parts into ChatGPT, Gemini, Claude or Grok and ask: “Explain this form like I'm not a lawyer. Tell me: (1) what I'm agreeing to, (2) any fees or deadlines, (3) what I can refuse or negotiate, (4) anything weird I should double-check.” You're still the one who decides. AI just speaks human so you're not guessing.
Real news from real sources. Every news bit links to the original story at the outlet that reported it (for example TechCrunch, Google and USC Viterbi School of Engineering).
When you shop in ChatGPT, a “Try on” button shows up on product listings. Upload a selfie or full-body photo and it shows roughly how the item might look on you, and a new Favorites feature saves the things you like to your ChatGPT Library. It's an AI picture, not a tailor, so still check the size chart. You can change or delete your saved photo in Settings, then Personalization.
Read it at TechCrunch →Google built Guided Vision in Gemini Live on Android with the blind and low-vision community. Share your camera and Gemini describes what's around you, answers follow-up questions and even coaches you to a better angle, like “pan slowly to the right.” It's handy for tiny nutrition labels or washing machine dials, and for anyone squinting at fine print in bad light. It can make mistakes, and it's not a cane replacement or for navigation.
Read it at Google →USC engineers and Cal Fire are building an AI tool called GenFire. It works backward from how a wildfire spread, using weather, terrain, vegetation and hilltop camera footage, to figure out where it most likely started. These investigations can take a very long time (one big California fire's origin report took almost 20 months), so faster answers could help with prevention. It's a research project just getting started, not a tool that stops fires today.
