Most people use ChatGPT one way: type a question, get an answer. It has a dozen other ways to behave sitting behind a plus button, a slider and a settings page. Here's every one, where it lives, and the exact words to build your own.

Before you start
15 modes
Every one checked against OpenAI's own help center this week.
11 free
Eleven of the fifteen work on the free plan.
1 sentence
That's all it takes to build your own mode.
A mode is any switch that changes how ChatGPT behaves before you type a word. Some are real buttons OpenAI built (Study, Temporary chat, the thinking picker, Health). Some are settings pages most people have never opened. And some you make yourself with one sentence and a saved memory.

The Five From The Video
Study mode: it teaches instead of answering
Click the + in the message box and choose Study (or just type @study, or go to chatgpt.com/studymode). A Study chip appears in your message box. From then on ChatGPT asks you questions, explains one step at a time, checks you understood, and builds practice questions from whatever you upload: notes, PDFs, photos of a textbook. To turn it off, delete the Study chip. Works on every plan and every model.
Incognito mode: nothing gets saved
OpenAI calls it Temporary chat. Open a new chat and click the pill-shaped Temporary button in the top right (a toggle on mobile). Nothing in that chat goes into your history, no new memories get created, and it isn't used for training. One honest detail: OpenAI keeps unsaved temporary chats for up to 30 days for safety review, then they're gone. Off the record from your account's point of view, not a vanishing act.
Genius mode: turn the thinking up
The picker sits in the message box on web and at the top of the chat on mobile. It runs from Instant up through Medium and High, with Extra High and the Pro levels on the Pro plan. On Free and Go, click + and choose Think. The higher you go, the longer it reasons before answering and the better it is at hard, multi-step problems. It's also slower and eats more of your limit, so save it for the questions that matter.
Health mode: it can see your real body data
In the sidebar, click More and then Health (it sits between Images and GPTs). Inside, open the menu and choose Apple Health, then pick which categories to share: sleep, steps, heart rate, workouts. Apple Health connects from the iPhone app only. You can also link supported US medical portals. Health is available to Free, Go, Plus and Pro users in the US, 18 and over, on web and iOS. Health chats are never used for training, and everything deletes within 30 days if you disconnect.
Maverick's tip
Health is built to support your care, not replace it. It will build a sleep plan around your actual numbers; it will not diagnose you. Treat it like a smart friend reading your Apple Watch, not a doctor.
Build your own modes
Start a new chat and type one sentence: "Whenever I type BRUTAL MODE, ..." then "Save this to memory." ChatGPT confirms, and the trigger word works in future chats. The next chapter has ten tested modes and the one thing the video leaves out: where the rule should really live.
Ten More Modes Hiding In The App
Work mode: it builds instead of chats
The Chat / Work switch at the top of ChatGPT. Work is the mode for multi-step jobs: it researches, writes files, uses a browser, connects to Gmail and Slack, and publishes sites. If you've ever asked for a spreadsheet and gotten a paragraph, you were in Chat. Plus and up.
Deep Research mode: a report, not an answer
In Work, type @Deep Research in front of your question. It goes away for several minutes, reads dozens of sources, and comes back with a cited report. Use it for anything you'd otherwise spend an afternoon Googling. Plus and up.
Voice mode: talk, interrupt, keep going
The voice button in the message box. The current voice model listens and speaks at the same time, so you can cut it off mid-sentence like a person. In Settings, then Voice, turn on Background conversations and it keeps listening while you use other apps. Free gets the mini voice model, paid plans get the full one.
Private project mode: memory that stays in one box
Create a Project from the sidebar, open its settings (the three dots) and switch Memory to Project-only. Now everything ChatGPT learns in that project stays there and never leaks into your other chats. Perfect for health, money, a client, or anything you don't want colouring every future answer. All plans.
Autopilot mode: scheduled tasks
Sidebar, Scheduled. Tell ChatGPT to do something every morning, every Friday, or when an email arrives, and it runs without you: a news brief, a weekly report, a reminder with research attached. You can pause, edit or delete each one from the Scheduled page. Plus and up.
Personality mode: pick a default voice
Settings, then Personalization, then Base style and tone. Seven options: Default, Professional, Friendly, Candid, Quirky, Efficient and Cynical. Candid is the closest built-in thing to brutal mode. Efficient strips the fluff. This applies to every chat, so it's the mode you set once and forget.
Lockdown mode: pull the plug on the internet
Settings, then Security, then Lockdown Mode. It switches off every network-enabled capability: web browsing, Deep Research, agent actions. What's left is a model that only knows what it was trained on and what you paste. Use it when you're working with something sensitive and want zero chance of an outside call. All plans.
Quiz mode: test yourself on anything
Just say "Quiz me on [topic]" or "quiz me on this" with a file attached. ChatGPT builds an interactive quiz, scores you, and explains what you missed. It's built into Study mode too, but works on its own in any chat. All plans.
Publisher mode: ChatGPT Sites
In Work, ask ChatGPT to build something and publish it, and it hosts the result at a live URL: a landing page, a portfolio, a tool, a game. You can change the URL from the site's settings. Plus and Pro.
Shopping mode: it compares for you
Ask "compare the best [thing] under $[price]" and ChatGPT returns products side by side with prices, specs and where to buy. Say what you care about (battery life, weight, no subscriptions) and it re-ranks. All plans.
Maverick's tip
Finances (sidebar, Pro plan, US): a dashboard of spending, bills, subscriptions and net worth. Codex (the third option on the desktop switch): the mode for building real software. Images, then Templates: start an image from a layout instead of a blank prompt. Library (sidebar): everything you've uploaded, searchable, with Google Drive and Dropbox connected.
Maverick's tip
Three of these stack. Work mode plus Deep Research plus a scheduled task is a research assistant that hands you a cited report every Monday morning without being asked.
Build Your Own Modes
The video's brutal mode is real and it works. I tested ten custom modes in fresh chats and tightened the wording until each triggered every time. Two rules came out of it.
Rule one: put the trigger word first, in caps, with a colon. "BRUTAL MODE: here's my idea" triggers reliably. Burying the word mid-sentence doesn't. Rule two: numbers survive, adjectives don't. "Under 150 words" and "exactly five bullets" get followed. "Keep it short" gets ignored by week two.
Mode 1: BRUTAL MODE
Whenever I type BRUTAL MODE: critique the work directly. Lead with the biggest flaw. No compliments, no reassurance, no closing encouragement. Name what I'm avoiding. Respectful about me, blunt about the work. Save this to memory.
Mode 2: EXPLAIN LIKE I'M 12
Whenever I type EXPLAIN LIKE I'M 12: plain words, exactly one analogy, no technical terms, under 150 words, and end with one question to check I got it. Save this to memory.
Mode 3: DECISION MODE
Whenever I type DECISION MODE: do not list options. Ask me up to three clarifying questions in one message and stop. After I answer, pick one answer and defend it in exactly five sentences. Save this to memory.
Mode 4: RECAP
Whenever I type RECAP: summarize this conversation only, as exactly five bullets, then one line starting with "Next action:". No preamble. Save this to memory.
Mode 5: DEVIL'S ADVOCATE
Whenever I type DEVIL'S ADVOCATE: argue the strongest case against my last statement in 3 to 5 numbered points, then a section titled "Actually worry about:" naming which points matter most. Save this to memory.
Mode 6: COACH MODE
Whenever I type COACH MODE: do not give advice or solutions. Ask exactly one question per message and wait. Maximum five questions. After the fifth answer, reflect back what I said in one paragraph, no recommendations. Save this to memory.
Mode 7: STEELMAN
Whenever I type STEELMAN: restate the position I'm arguing against in its strongest, most charitable form, as its best advocate would, under 150 words, then stop. Save this to memory.
Mode 8: SHRINK IT
Whenever I type SHRINK IT: rewrite whatever I paste at half the length, keeping every fact and the original tone. Output only the rewrite, no commentary. Save this to memory.
Mode 9: FIVE WHYS
Whenever I type FIVE WHYS: take the problem I just described and ask "why" five times in sequence, one per line, then name the likely root cause in one sentence. Save this to memory.
Mode 10: PLAIN ENGLISH
Whenever I type PLAIN ENGLISH: translate the jargon or contract clause I paste into everyday language in one short paragraph, then one line: "What this means for you:". Save this to memory.
Maverick's tip
Saved memories are short paraphrased facts, so the numbers get dropped. Put the modes in Settings, then Personalization, then Custom instructions, one line each (5,000 characters fits all ten). They're injected word for word into every chat. To check one, type the trigger alone and ask "what rule are you applying?"
Mistakes That Make Modes Stop Working
| Mistake | Fix |
|---|---|
| Custom modes stored only in memory | Put the rules in custom instructions. Memory compresses; instructions don't. |
| Trigger word buried mid-sentence | Trigger first, caps, colon. "BRUTAL MODE: ..." |
| Vague rules | Numbers: "under 150 words," "exactly five bullets," "one question per message." |
| Two jobs in one turn | "Ask three questions, then decide" can't happen in one reply. Say "and stop." |
| Expecting Study mode to persist | It's a chip in the message box. New chat, add it again, or use @study. |
| Thinking it's private because of Temporary chat | Nothing saved to your account, but OpenAI keeps it 30 days for safety. Use Lockdown for no-internet work. |
| Running genius mode on everything | Slower and burns your limit. Instant for quick stuff, high levels for the hard question. |
| Trying Apple Health on the web | The connection is iPhone-app only. Connect there once, then use it anywhere. |
| Want to... | Use | Path |
|---|---|---|
| Learn something properly | Study, Quiz | Plus button, Study; or "quiz me on..." |
| Ask something off the record | Temporary chat, Lockdown | Temporary (top right); Settings, Security |
| Get the best possible answer | Thinking picker | Message box picker, slide up |
| Plan around your body | Health | Sidebar, More, Health; Apple Health from iPhone |
| Get things built, not described | Work, Sites, Scheduled | Chat/Work switch; ask to publish; Sidebar, Scheduled |
| Change how it talks to you | Personality, Custom modes | Settings, Personalization |
| Keep a topic sealed off | Project-only memory | Project settings, Memory |
Maverick's tip
Open Settings, Personalization. Set your Base style. Paste three of the custom modes into Custom instructions. Then start a new chat, type BRUTAL MODE and your current project. You'll know in thirty seconds whether it's worth the other twelve.
