3 useful ways to start.
Choose a reviewed task here, then use its canonical page for the complete workflow, reusable prompt and checks.
01Canonical task guide
You have scattered bullets, half-finished thoughts and a deadline. You know what happened, but the person reading the update was not there and should not have to decode your notes.
Turn rough notes into a clear update
A concise update that tells the reader what changed, what is blocked and what happens next, while keeping uncertain details visibly marked for you to confirm.
Why ChatGPT may fit
A strong starting point when you want to sort scattered notes into a structured draft and refine the wording through a few quick conversational passes.
You still check
Which detail matters most to this reader, not simply which detail appeared most often · Every name, date, number, commitment and owner · Whether the language sounds like you and every line is appropriate to share
You need more than a quick answer, and you want to see which claim came from which source rather than take a tidy summary on trust.
Research a topic with reliable sources
A focused briefing that keeps its links, its disagreements, its gaps and your next questions all in view.
Why ChatGPT may fit
Its reviewed guide includes Deep Research, which works for several minutes across many sources and returns a report with citations you can click through.
You still check
Whether the sources are primary and still current · Whether each citation actually says what the claim says · What is missing, and whether it applies to your case
Models change how much thinking you get. Features let ChatGPT search, research, work with files or make things. Start with the simplest choice that fits the job.

What the buttons actually do
ChatGPT’s main features.
You do not need all of them. Learn the two or three that solve work you already have, then add more when a real need appears.
Chat
The everyday conversational workspace for asking, drafting, explaining and thinking something through.
Use it when
You can describe the task in words and want to work back and forth.
Try this
Give it a real audience, desired outcome, source material and constraints.
You still do
Supply context and decide whether the answer fits reality.
Search
Finds current information on the web and gives you links to inspect.
Use it when
You need a recent fact, a current recommendation or a quick source-backed answer.
Try this
Ask for the latest answer in your location and request primary sources.
You still do
Open the sources and check that they support the answer.
Deep Research
Takes longer to investigate a question across many sources and produces a cited report.
Use it when
The question affects a real decision and a quick search is not enough.
Try this
Describe the decision, scope, preferred sources and what would change your mind.
You still do
Judge source quality, missing perspectives and whether the conclusion applies to you.
Usage and access depend on your ChatGPT plan.
Files & data analysis
Reads uploaded documents and can use code to analyse tables, spreadsheets and CSV files.
Use it when
The answer should come from material you already have.
Try this
Ask for a data-quality check before asking for conclusions or charts.
You still do
Protect sensitive information and validate important calculations.
Projects
Keeps related chats, files and instructions together around an ongoing goal.
Use it when
You return to the same body of work and are tired of repeating the context.
Try this
Create one Project for one clear outcome, then add a short working brief.
You still do
Keep the context current and separate work that should not share information.
Voice
Lets you speak with ChatGPT instead of typing.
Use it when
Talking is easier: for brainstorming, language practice, accessibility or hands-busy work.
Try this
Ask it to interview you one question at a time, then summarise your thinking.
You still do
Review any details that may have been misheard or oversimplified.
Images
Understands images you share and can generate or edit images from instructions.
Use it when
A visual example will communicate faster than more words.
Try this
Describe the purpose, subject, composition, mood, colours and what must not appear.
You still do
Provide taste, check accuracy and confirm you have the right to use the result.
Scheduled Tasks
Runs supported prompts later or on a recurring schedule and notifies you when they are complete.
Use it when
A reminder, briefing or check needs to happen repeatedly.
Try this
Schedule a narrow weekly briefing with a clear location, topic and output format.
You still do
Review the result and stop tasks that no longer help.
Available plans and task limits vary.
Apps
Connects ChatGPT to supported external tools and data so it can find context or take approved actions.
Use it when
The useful information lives outside the chat and a supported connection exists.
Try this
Start read-only with a low-risk information-finding task.
You still do
Understand permissions and approve consequential actions carefully.
App access and controls depend on plan, region and workspace settings.
ChatGPT Work
A longer-running workspace for producing editable documents, spreadsheets, presentations, reports and other finished work.
Use it when
The task spans multiple sources and needs a deliverable, not just an answer.
Try this
Give it a brief, files, quality bar and checkpoints where it should wait for you.
You still do
Direct the work, approve key choices and review the final deliverable.
Availability and limits depend on plan and rollout.
Codex
A software-development agent for understanding code, making changes and running checks in a real repository.
Use it when
The outcome is working software rather than an explanation about code.
Try this
Give it the repository, desired behaviour, constraints and acceptance checks.
You still do
Own the product decision, review changes and approve deployment.
Current standard Chat choices
More effort is not automatically better.
Use the fastest mode that gives you a good enough answer. Move up when the problem is harder, or when the first answer falls short.
ChooseUnder the hoodUse it forEffort
InstantGPT-5.5 Instant
Quick questions, first drafts, rewrites and everyday back-and-forth.
Fastest
MediumGPT-5.6 Sol
A solid default when the answer needs real thought but not a long investigation.
More thought
HighGPT-5.6 Sol
Complex comparisons, planning, technical work or a problem where mistakes are costly.
Extended
Extra HighGPT-5.6 Sol
The hardest work when waiting longer is justified. Available on selected plans.
Longest
ProGPT-5.6 Sol Pro
Difficult or long-running tasks where capability matters more than speed. Available on selected plans.
Specialist
Keep it simple:
Start with Instant. If the answer is shallow, the problem is complex or you want a more careful comparison, try Medium. Move to High only when the extra wait is worth it.
Which choices you see depends on your ChatGPT plan and rollout. ChatGPT may also switch an eligible request from Instant to Medium automatically.
