Summary of "You're Using 10% of ChatGPT | 92% Never Open This Menu"

Key premise

92% of ChatGPT users never open the settings menu, so many built‑in features go unused. The video walks through 17 must‑use features that convert ChatGPT from a basic chatbot into a productivity system.

Foundational settings you should change first

Data controls
- Turn off “Improve the model for everyone” to prevent OpenAI from using your chats for training (important for confidential/work data).
- Path: Settings → Data Controls.
Memory controls (Personalization → Memory)
- Turn memory off or selectively delete stored memories; review what ChatGPT already remembers about you.
Custom Instructions
- Save role, audience, tone, and preferred output format once so every conversation applies that context.
- Path: Settings → Custom Instructions (two fields: what to know about you; how to respond).
Temporary chat (ephemeral mode)
- Use for sensitive queries; chats aren’t saved/used for training.
- Access via the sidebar icon or the keyboard shortcut Ctrl/Cmd + Shift + ;.

Prompting skill (not a toggle)

Good prompting is specific and structured: include audience, length, tone, and format.
Example prompt: “Write a 500‑word blog post for busy entrepreneurs…”
Recommended resources:
- Creator’s “Seven Layers of AI Prompting” framework (free video / linked in description).
- Coursera’s Prompt Engineering specialization by Dr. Jules White (Vanderbilt). A Coursera Plus promo is mentioned.

Everyday efficiency features

Projects
- Smart folders for clients/topics: upload files, set project‑specific custom instructions, and keep related chats together.
Search past conversations
- The sidebar search bar surfaces prior chats by keyword/date/project — turning history into a searchable knowledge base.
Voice mode (mobile)
- Natural back‑and‑forth voice conversations; tap the headset/headphone icon in the app.
Shared link expiration
- When sharing conversations, set link expiration (7 / 30 / 90 days) to avoid leaving shared chats publicly accessible indefinitely.
File upload
- Upload PDFs, images, CSVs, spreadsheets, code files for summaries, debugging, or trend analysis.
- Tips: use the paperclip icon in the chat input; typical file limit ~512 MB (PDFs/images recommended <25 MB).

Hidden / multimodal capabilities

Multimodal prompts - Combine text + images + files in one prompt (e.g., product photo + brand guidelines → tailored captions). Richer inputs produce better outputs.
Canvas mode - Split‑screen collaborative document (left: conversation; right: live document). AI can edit, suggest, and comment — useful for long‑form writing and code. - Access via “Open Canvas” or the canvas button.
Web browsing - Enables real‑time internet search and citations (useful for news/recency). Enabled by default for Plus users and can be toggled in settings.
GPT Store / Custom GPTs - Browse prebuilt specialist GPTs (writing coach, data analyst, resume builder, etc.). You can review and use them from the sidebar (“Explore GPTs”).

Advanced customization & automation

Build your own custom GPT - Create specialized assistants by adding instructions, knowledge base files, and conversation starters. The guided builder is quick (minutes).
Shopping assistant (shopping bag icon) - Product research comparator: analyzes specs, compares prices/reviews across retailers, outlines trade‑offs, and gives recommendations with links to purchase.
Agent mode (automation / app integrations) - Connect ChatGPT to apps (Google Calendar, Gmail, Slack, Notion, etc.) so the model can take actions: schedule events, send invites, read/summarize emails, write into Notion, and more. - This moves ChatGPT from a passive chatbot to an actionable assistant that can delegate cross‑app work.

Overall claim

You don’t need every feature, but using several (especially settings, custom instructions, projects, file upload, and agent mode) can dramatically improve productivity. The creator guarantees at least five features will be impactful.
