A long comparison is not automatically a good decision. Deep Research becomes useful when you specify what the result must help you choose. This tutorial produces a shortlist for a tutorial creator, with evidence for the features that matter and a short hands-on test to settle the remaining questions.
Checked: 10 November 2026. Features and menu labels can vary by plan, workspace and rollout.
Before you start
A ChatGPT account offering Deep Research and a comparison you can scope clearly. Check your available allowance before starting. You can practise with public product pages; there is no need to connect email, private storage or client accounts for this example.
1. Write the requirements first
Create a short list of non-negotiables, preferences and exclusions. For a Mac tutorial creator, the essentials might be screen recording, readable exports and a face camera. Transcript editing may be a preference. State the operating system and whether a subscription is acceptable.
2. Open Deep Research
Use the plus menu and choose Deep research where offered. In ChatGPT Work, the tool can also be available through the relevant plugin or tool controls. Availability differs between accounts. If it is absent, use ordinary web search for a smaller comparison and follow the same evidence checks.
3. Set boundaries for the investigation
Name the products or limit the shortlist size. Ask for official feature documentation, current pricing pages and release notes. Request the date checked and the currency or billing assumptions for any price. Exclude affiliate rankings unless you deliberately want a separate view of reviewer opinions.
4. Review the proposed approach
If ChatGPT asks clarifying questions or offers a research plan, correct the criteria before the longer investigation runs. Remove interesting but irrelevant questions. A report about twenty features you do not need can obscure the one limitation that would rule a product out.
5. Audit the comparison table
Inspect the sources for every essential feature. Distinguish a genuinely missing feature from one the researcher could not verify. Check whether a limit applies to the free plan, a particular operating system or an older version. Keep unsupported cells labelled as unverified.
6. Turn the shortlist into a trial
Choose two finalists and write a repeatable ten-minute test. Use the same source material, export target and success criteria for both. Record what you observed rather than changing the comparison to fit the tool you liked first. A documented product claim and your own successful test answer different questions.
A prompt to adapt
Compare [three tools] for a Mac creator making short software tutorials. Essentials: [list]. Preferences: [list]. Use current official documentation and pricing pages, recording dates and billing assumptions. Return an evidence table, unresolved questions, a shortlist with reasons and a ten-minute trial for each finalist. Do not treat an unverified feature as definitely absent.
Check the result
Open the original pages behind the decisive rows. Recheck a current price before paying. If two sources disagree, record the discrepancy and look for a dated release note or contact the vendor yourself. Do not let the AI silently choose which version to believe.
Common questions
Is Deep Research always better than search?
No. A focused feature question may be answered faster with ordinary search. Use a longer investigation when there are several related requirements and sources to reconcile.
Should I connect my private apps for this?
Only when their information is necessary and you are authorised to use it. A comparison of public software features usually does not need access to a private inbox or drive.
