Octo vs ChatGPT
A study chat, or a course built for you.
ChatGPT's study mode is a good way to work through a problem step by step. Octo does something different: it interviews you, designs a course around your goal, and writes every lesson for you. Here is how they compare.
What ChatGPT offers for learning
OpenAI describes study mode as a learning experience that helps you work through problems step by step instead of just getting an answer. You choose it in a chat and ask questions; it guides you with questions of its own, can quiz you, and accepts notes or a photo of a problem as context. It is available on ChatGPT's free plan.
Separately, OpenAI runs OpenAI Certifications, courses inside ChatGPT that certify AI skills.
What Octo does differently
Octo is built around one course for one person. You tell it what you want to learn in a sentence, and:
- It interviews you about your goal, what you already know and your deadline.
- It designs a curriculum of modules and lessons, which you can reshape in chat before anything is written.
- It writes every lesson for you, with an Ask AI tutor beside each one.
- When you finish, you get a certificate anyone can verify.
Side by side
| ChatGPT study mode | Octo | |
|---|---|---|
| Starts from | A question in a chat | One sentence about what you want to learn |
| Structure | A conversation | A course of modules and lessons, planned before it is written |
| Built around | The problem in front of you | Your goal, your level and your deadline |
| Your own material | Attach notes, a syllabus or a photo | Attach documents when you start a course |
| Tutor while you learn | The chat itself | Ask AI beside every lesson |
| Certificate | Not from study mode; OpenAI Certifications cover AI skills | A verifiable certificate for every course you finish |
When to use which
Use ChatGPT when you have a specific problem and want to reason through it now. Use Octo when you want to learn a subject end to end, in order, with a plan made for your situation and something to show for it at the end.
Many people use both: a chat for the question in front of them, a course for the skill behind it.
