Give ChatGPT context so it works for you

Every time you start a new chat, ChatGPT starts from scratch. It does not know your role, your team, your preferred writing style, or what you are working on. Without that background, it gives you a generic response that needs rounds of editing. Context is the information you give ChatGPT so it can respond in a way that fits your situation. The more relevant detail you provide, the less time you spend going back and forth. We will show you how to use specific ChatGPT features to build in context automatically, so you can do less setup and more of the work that matters. This page will show you how to:

Understand context

Learn what context means and why it changes your output

Add context to chats

Use files, instructions, and memory to enrich conversations

Use built-in tools

What counts as “context”?

Think of context like briefing a new colleague before they start a task. You would not hand someone a vague request and expect a perfect result. You would tell them who you are, what you need, and how you like things done. In ChatGPT, context comes from several places:

What you type or paste

The text in your message, including any background, examples, or reference material you include directly in the chat.

Files you attach

Documents, spreadsheets, images, and PDFs you upload using the ”+” button. ChatGPT reads these and uses them to shape its response.

Custom Instructions

Persistent preferences you set once in Settings. These apply to every new conversation automatically.

Memory

Details ChatGPT saves from your past conversations, like your role, team size, or preferred format.

Company Knowledge

Connected platforms like Google Drive, SharePoint, and Slack that ChatGPT can search to find your organisation’s files and information.

Deep Research

A research mode that reads through hundreds of web pages and documents to build a comprehensive answer for complex questions.
You do not need all of these at once. Start with one or two and build from there. Even a single sentence of context, like “I’m a project manager writing for my leadership team”, changes the output significantly.

The what, when, how of giving context

When you brief a colleague, you naturally explain what you need, when it applies, and how you want it done. The same framework works for ChatGPT.

What

Tell ChatGPT the task and include background. Paste in meeting notes, a brief, or a document for it to reference.

When

Set the situation. Is this for an executive summary due Friday? A client email response? A brainstorm with no wrong answers?

How

Describe the format and tone. Should it be a bullet list, a two-paragraph summary, or a formal report? Friendly or direct?
This is the same “what, when, how” structure used to brief any team member, human or AI. If you can explain the task to a colleague, you can explain it to ChatGPT.

How to add context in your conversation

There are several ways to give ChatGPT more to work with during a chat. Here is what each one does.

Paste text or add files

Chatgpt Guide Plus IconClick the ”+” icon in the chat bar to access options for adding context:
  • Add photos and files
  • Deep research
  • Agent mode
  • Create image
  • Web search
  • Canvas
  • Study and learn
These options let you bring in documents, images, or specialised modes depending on what your task requires.

Custom Instructions

Chatgpt Guide Custom InstructionsCustom Instructions act as a permanent briefing that ChatGPT reads before every response. Go to Settings, then Personalization, and make sure “Enable Customization” is turned on.In the Custom Instructions box, describe the behaviour, style, and tone you want. For example:
  • “Use concise, action-oriented responses”
  • “Be brutally honest and critical when responding”
  • “Be a supportive brainstorming and thinking partner”

Voice Mode

Chatgpt Guide Voice ModeSpeak directly to ChatGPT in a natural, conversational way.Voice Mode listens to your words, pauses, and tone, making interactions feel more natural than text alone.The button changes to a “breathing” animation when actively listening, and the AI responds out loud while transcribing your conversation.
Talk as you would with a colleague. No need for perfect prompts.

Direct ChatGPT with roles

Give ChatGPT a clear role to focus its response. Pick one of these three starting points based on your task.
Role + format + word limit = you are 80% of the way to a useful output.

Enable and manage Memory

Memory lets ChatGPT remember details across conversations. Once “Reference saved memories” is enabled in Settings, ChatGPT builds a knowledge base from information you share over time. Chatgpt Guide Memory There are two types of memory, and two ways to add them:

Automatic Memory

Adding Memory 1Share a detail or preference during a chat. If ChatGPT thinks this will be useful later, it saves it automatically and shows the “Updated saved memory” notification.

Manual Memory

Adding Memory 2Tell ChatGPT directly: “Save this to memory.” It stores the detail and confirms with the same notification. Use this when you want to be specific about what it remembers.
Saved Memories are details you explicitly ask ChatGPT to remember, or that it saves automatically during a conversation. These persist across all future chats.Chat History lets ChatGPT reference your recent past conversations to give more relevant responses. Think of it as short-term awareness of what you have been working on recently.You can turn either one on or off independently in Settings, then Personalization, then Memory.
Ask “What do you remember about me?” in any chat. You can also go to Settings, then Personalization, then Manage Memories to see, edit, or delete individual saved memories.
No. Saved memories are stored separately from your chat history. Deleting a chat does not remove any memories created during that conversation. To fully remove a memory, delete it from Manage Memories in Settings.

Canvas tool

Canvas provides a dedicated side-by-side workspace for creating and editing written documents within ChatGPT. Unlike standard chat responses, Canvas opens a full editing environment where you can view, select, and revise specific sections of your document.

Where to access

Start a chat and ask ChatGPT to generate a document, draft a report, or modify existing written material. Canvas launches automatically when suitable. You can also open it manually by selecting the ”+” button, then “More”, then “Canvas.”
Canvas Tool Access Pn

Editing in Canvas

Select specific sections of your document and request changes to just those areas. For example, highlight a paragraph and ask for more detail without affecting the rest of the document.
Editing In Canvas Pn

Built-in editing tools

Canvas includes one-click tools that appear in the bottom right-hand corner when you hover over the edit button. You can polish grammar and sentence structure, adjust the document’s complexity, change its length, and view suggested edits.
Built In Editing Tools Pn

Sharing and exporting

Once your document is complete, you can share a link to the entire conversation or create a link specifically to the Canvas document. If you make updates after sharing, anyone with the Canvas link can see the new edits. Canvas documents can be downloaded as PDF, Word, or Markdown formats.
Sharing And Exporting Pn
Canvas works best for generating first drafts and implementing major structural revisions. It is particularly effective for transforming rough notes into refined documents or reformatting existing content with an improved writing style.
For ongoing minor adjustments and final polish, you might currently find it quicker to make changes manually. This function continues to develop and may not yet offer the seamless experience available from other professional writing tools.

Deep Research

Deep Research is ChatGPT’s most comprehensive approach to answering complex questions. It conducts multi-step web investigations, reading through hundreds of documents and web pages, cross-checking sources, and building a complete picture of your topic.
Chatgpt Deep Research Pn

Where to access

Click the ”+” button in your chat and select Deep Research. You can then choose the sources it draws from. Web search enables internet access, while Company Knowledge lets it draw from your organisation’s connected platforms.
Where To Access Pn

When to use Deep Research

Questions that take hours

Use it for research that would normally take two or more hours of manual searching and reading.

Multiple viewpoints

Use it when your topic requires cross-domain insights or comparing several perspectives.

High-stakes decisions

Use it for strategic decisions where depth and accuracy are worth the time.
Most paid plans include 25 queries per month. Save Deep Research for the complex, high-stakes questions where comprehensive analysis creates real value.

Company Knowledge

Company Knowledge lets ChatGPT search and reference information from across your organisation’s connected platforms, including Google Drive, SharePoint, Slack, GitHub, Gmail, Outlook, HubSpot, Salesforce, and more. Ask ChatGPT to find documents, summarise strategies, or reference past decisions. It searches your connected platforms automatically. Company Knowledge is read-only, so your files remain secure and unchanged.

File upload from cloud storage

You can upload files directly from Google Drive or SharePoint by clicking the ”+” icon in the chat. After initial setup via the “More” menu, these options appear in your main menu. This lets you import specific documents from your cloud storage without downloading them first.
File Upload Pn

Use Company Knowledge in chat and Deep Research

Activating “Use Company Knowledge” allows ChatGPT to search your files even if you do not specify exact documents. This is useful for finding or summarising information across multiple files. You can also access Company Knowledge when using Deep Research, letting you specify which information sources it draws from.
Company Knowledge In Chat Pn

Syncing Company Knowledge

Turning on Sync means ChatGPT automatically references your connected platforms in every chat. You do not need to click “Use Company Knowledge” each time. ChatGPT remembers information from sources like Google Drive or SharePoint, which helps it find relevant information faster.
Company Knowledge is unavailable when using the Pro model, custom GPTs, Projects, or Voice Mode.
