Hekko vs ChatGPT for Students (2026): Which One for Your Lectures?

Hekko and ChatGPT don't do the same job. Hekko records your lecture and gives you back notes, a cheat sheet, quizzes and flashcards without you writing a single prompt. ChatGPT is a general assistant: brilliant for explaining a concept or answering a question, but you have to bring it the material and ask for what you need. If most of your course is spoken in class, Hekko saves you the work. If you need a tutor to talk things through, ChatGPT is better.

Full disclosure: Hekko is our product. That's why every ChatGPT detail below comes from OpenAI's own pricing page and help center, and why we say plainly where ChatGPT wins.

TL;DR

The honest answer: use Hekko to capture and revise from your lectures, and ChatGPT to understand what's still unclear. Many students use both.

• Pick Hekko if you want every lecture turned into revision material automatically, on your phone, in any language.
• Pick ChatGPT if you mostly need explanations, feedback and back-and-forth on material you already have.

Hekko vs ChatGPT at a glance

What's the difference between Hekko and ChatGPT?

Hekko is a study tool with one workflow, from lecture to revision; ChatGPT is a general-purpose assistant that can help you study if you steer it. With Hekko you press record at the start of class and get a finished study kit at the end. With ChatGPT you get a blank chat: the quality of what comes out depends on what you upload and on how well you prompt it.

That difference matters most on busy weeks. Five lectures a week means five transcripts to get into ChatGPT, five prompts to write, and five sets of answers to reorganize into something you can revise from. Hekko does that part for every course, the same way each time.

Can ChatGPT record a lecture?

Yes, but with limits that matter for students. ChatGPT's record mode is only available on paid plans (Plus, Pro and business or education workspaces) and only in the macOS desktop app: not on Windows, not on the web, and not on your phone. OpenAI caps sessions at 4 hours and says record mode "works best in English today". What you get is a meeting-style summary saved as a canvas.

Hekko records on the web and in its iOS and Android apps, so you can record from your phone in a lecture hall. It handles recordings of three hours or more, writes notes in the language of the class, and you can add the professor's slides, PDFs or photos of the board so the notes match what was shown. The audio is transcribed and then deleted; only the text is kept.

Which one is better for revising for exams?

For revision, Hekko is ready to use; ChatGPT is ready to build with. Every Hekko course comes with a cheat sheet, quizzes and flashcards generated from that lecture, so you can start testing yourself right away, and Hekko then brings each course back as a short quiz review at growing intervals (spaced repetition). Research on retrieval practice consistently shows that answering questions beats rereading (how to revise effectively).

ChatGPT can also quiz you, and it has a dedicated study mode that guides you step by step instead of just giving the answer. It's genuinely good at that. But you have to start the session, give it the material, and keep track yourself of what to review and when.

Hekko has a chat too, Ask Hekko, but it only answers about your own courses: ask it to explain a passage of your notes, or to build a mock exam from one course or a whole folder. For questions that go beyond your lectures, ChatGPT is broader.

Is ChatGPT's free plan enough to study from lectures?

For short questions, yes; for full lectures, rarely. OpenAI's pricing page lists a maximum input of about 12 pages of text on the Free plan for its Instant model, and about 40 pages on Go and Plus. A full lecture transcript can easily go beyond that, and file uploads are limited on Free. Record mode isn't included at all.

Hekko's free plan gives you 2 complete courses a month, each with notes, cheat sheet, quizzes and flashcards, with no card. It's enough to test it on a real week of classes, not to cover a whole semester.

When is ChatGPT the better choice?

ChatGPT is the better choice when you need a conversation rather than a document:

• Understanding a hard concept: ask it to explain the same idea three different ways until one clicks.
• Working through exercises: study mode walks you through a problem instead of solving it for you.
• Material that isn't a lecture: an article, a dataset, a practice exam from a previous year.
• One subscription for everything: if you already pay for Plus for other reasons, you won't want another tool for occasional use.

And Hekko's limits, honestly: the free plan stops at 2 courses a month, and Hekko isn't a general assistant for everything else you do.

Can you use Hekko and ChatGPT together?

Yes, and it's a good combination. Record the lecture with Hekko to get complete notes and a cheat sheet, then export the notes to PDF or Word and bring the part you don't understand to ChatGPT. You capture everything without typing, and you use ChatGPT for what it does best: explaining.

Verdict

• Most of your course is spoken in class → Hekko. You get revision material after every lecture without writing a prompt.
• You mostly need explanations and help with exercises → ChatGPT.
• You want both → Hekko to capture, ChatGPT to dig deeper.

The simplest test: record one real lecture with Hekko, and try to get the same result with ChatGPT from the same class. Keep the one you actually revised from. For more tools, see our comparison of the 9 best AI note-taking apps for students.
