ChatGPT
“Rebounding with Astra” — the veteran that fell behind, then turned the game around
What is ChatGPT?
ChatGPT is a conversational AI from OpenAI and the best-known tool for handling writing, images, data analysis, and voice in a single window. Since GPT-6 Astra, released in September 2026, it can also operate your computer and browser directly.

- 2Strong at working directly with your computer and browser
- 3Four plan tiers still make choosing a hassle
What sets it apart
These are the differences we found by running the same material through several tools in our training sessions.
It controls the screen directly
Starting with GPT-6 Astra, released in September 2026, OpenAI puts direct control of the computer and web browser front and center. You can hand it tasks like filling in forms or work that spans multiple steps. Security-related requests, however, shipped in a restricted version, so decide up front how much to delegate before using it at work.
You can try quite a lot for free
Even the free plan gives you generous text chat, and you can try image generation, deep research, and voice within usage limits. If you want to try AI for the first time without entering a card, it still has the lowest barrier to entry.
Features that work beyond the chat window
The official feature table lists Excel, Word, PowerPoint, and Google Sheets extensions, plus scheduled tasks and a built-in browser. It means ChatGPT keeps moving beyond Q&A toward actually carrying out work.
⚖️ The weaknesses are clear, too
Now that pricing is split into Free, Go, Plus, and Pro, it has become hard to explain what each tier covers. The Go plan on the official pricing page carries the notice this plan may include ads, and for personal plans, the 'use of user content for model training' row is marked 'can opt out'. That means you have to turn the default off yourself.
💡 In plain EnglishIt is like an old department store. It carries everything, but the floor layout changes often, so you have to relearn where things are each time you visit.
In training rooms, “AI means ChatGPT” is still the strongest perception. So for training managers, it helps more to explain what each plan can do today and what has changed than to introduce yet more features.
Same job, different approach
You have been asked to choose a single AI tool for the whole company
The old way
- Choosing it just because it’s the best-known name
- Buying the same paid plan for every employee
- Only a few people use it, and the other accounts sit unused
- Next year, you start over with the same problem
Using ChatGPT
- Have people try the free plan for a month
- Ask everyone to list the three tasks they actually used it for
- Pay only for the plan each task needs
- Explains training-use settings and the items banned from company use
Common uses
Drafting and editing
Get first drafts of emails, announcements, and proposals quickly, then refine them. Specify a tone and ask for three versions to make choosing easier.
Reviewing tables and numbers
Paste in a table and ask about unusual values or trends. Always verify calculated results against the original file.
Scheduled research
Scheduled tasks and the built-in browser collect recurring research results for you. Have it list source URLs too, so you can verify them.
Who it’s for
Best for
- ✓You want one tool that covers most of your needs
- ✓Anyone starting out with AI for free
- ✓Anyone who wants images and voice in a single account
Better served by other tools
- –Best if your work centers on reading long documents and polishing text
- –Best if integration with Google Docs and Gmail matters most
- –Anyone who can’t tolerate frequent changes to pricing and settings
Can we use it at work?
The questions that adoption leads and security teams ask first.
Please verify: Default training-use settings and retention periods vary by plan and change often. Before you adopt a plan, check them against the official terms and data controls documentation.
10-minute quick start
- 1
Create a free account, paste in an email or announcement you wrote today, and ask it to polish it.
- 2
In Settings, find the option that controls whether your conversations are used to train models, and set it the way you want.
- 3
Write down the tasks you actually used it for over one week, then pick only the features those tasks need.
- 4
Only then decide which plan you need. There is no reason to start with a top-tier plan.
Copy-and-paste prompts
Replace only the [bracketed] parts, then paste it in.
Turn the content below into an email to a client. Give me three versions: ① polite and formal ② short and practical ③ relationship-focused. [Content to convey]
Find anything in the table below where the totals don't add up or the figures don't match. For items you aren't sure about, don't state a conclusion; mark them as 'needs verification'. [Paste table]
Find recent sources on [topic] and summarize them into three key issues. After each paragraph, list the source URLs you used, and flag anything that could not be verified.
Turn the material below into a 2-hour in-house training session. Split it into an intro, three main parts, a hands-on exercise, and a wrap-up, and add one discussion question for participants in each part. [Paste material]
From the meeting notes below, pull out only the action items where who, what, and by when are clear, and put them in a table. List items with no clear owner separately and label them “Needs confirmation.” [Paste meeting notes]
Using it with other tools
Linking two or three tools changes your work more than any single tool does.

Before you start
- Always check numbers and quotations against the original source. Values that look plausible but are wrong are the biggest risk.
- Check the training-use setting first. Many people never change the default.
- Plan names and model names change often. If you hard-code a version into training materials, the guidance quickly goes out of date.
- Never enter customer personal data, contract amounts, or unreleased results, on any plan.

Agentic AI — the version that does the work itself
ChatGPT can do more than answer in chat. Depending on your plan, it can run tasks on its own at set times, or open the web and work through multi-step tasks.
Scheduled tasks
Runs the same task repeatedly at set times and sends the results to your chat. Use it for regular research or a morning briefing.
- Log in to ChatGPT on the web or in the app and turn the feature on. No separate installation is needed.
Built-in browser
A feature where ChatGPT browses the web on its own and finds the sources you need. It removes the step where a person searched and copied results over.
- Turn it on inside ChatGPT — no separate installation needed.
Codex
An agent you can hand coding tasks to. It started in software development but is also used for file conversion and automation scripts.
- Sign in with your ChatGPT account — also available on desktop.
Setup steps and requirements follow the official documentation. ChatGPT official pricing ↗
ChatGPT’s drawbacks
We don’t just list the positives. Here is what fell short when we used it.
- The answers run long
It often returns background you never asked for, so you end up cutting about half before pasting it into a report. You have to ask for brevity separately to get the length you want.
- Korean output can read like a translation
The meaning is right, but the endings and connectors read like a translated English sentence, so a person should polish it once more if it is going to customers.
- Past conversations are hard to find
As conversations pile up, it takes time to find what you worked on last week. Titles are generated automatically, so you end up with several similar names that are easy to confuse.
