ChatGPT Cheat Sheet

You are a ChatGPT cheat sheet written at the level of capabilities instead of version numbers, covering custom GPTs, memory, canvas, file handling, images and voice. You have been activated to hand over 25 one-line prompts that change the output.

CHATGPT CHEAT SHEET ChatGPT gives most people average answers because most people ask average questions and never open the features that actually change output quality. This cheat sheet fixes both: what the tool is genuinely good and bad at, the features worth learning, and the phrasing that reliably changes what comes back - written at the level of capabilities, not version numbers, so it doesn't go stale the next time a model updates. WHAT EACH FEATURE ACTUALLY DOES Custom GPTs - A custom GPT is a version of ChatGPT with fixed instructions, and optionally its own files or connected tools, saved so you don't retype the setup every time. Worth building for any task you repeat with the same rules - a specific writing style, a specific analysis format - rather than pasting the same instructions into a fresh chat each time. Memory - ChatGPT can retain facts about you or your preferences across conversations if memory is enabled. Useful for standing preferences (your role, your writing style, recurring projects); not a substitute for pasting in the actual material a specific task needs - memory holds facts about you, not documents. Canvas - A side workspace for drafting and editing a document or piece of code with targeted, section-level revisions, separate from the back-and-forth chat. Ask for canvas explicitly when you're going to iterate on one piece of writing or code over several turns rather than reading a single answer once. File handling - Upload PDFs, spreadsheets, images, and text files and ask ChatGPT to work directly from their content. Be specific about the extraction you want - "list every date, party, and obligation in this contract" produces a checkable table; "summarize this" produces a paragraph you'll still need to verify against the source. Images - ChatGPT can generate and edit images from a text description, and can also read and describe an image you upload. For generation, describe the composition, style, and specific details you want rather than a single adjective - "a cluttered wooden desk lit by late afternoon window light" beats "a nice desk." Voice - Real-time spoken conversation, useful for brainstorming, practice conversations, or hands-free tasks. Treat it as a fast draft mode - review anything that matters in text before you rely on it. 25 ONE-LINE PROMPTS Writing 1. "Rewrite this in [X] words, keeping every number and name exact." 2. "Give me three headline options ranked by how much they promise versus how plain they're willing to sound." 3. "Cut this by a third without losing any concrete detail - only cut abstraction and hedging."
