Lesson 3 · Rendering, step by step
So far we have talked about state.
Now, what does rendering mean?
React calls your component.
It gets back a description of the UI.
Nothing is painted at this point.
Then React compares the two trees.
Only the differences are committed.
Keys help it match list items.
Without them, items can lose state.
Effects run after the commit.
That is why you see the new value there.
Let us look at an example.
Summary
Rendering calls components; it does not paint.
The commit phase writes only what changed.
Keys keep list items stable between renders.
Effects run after the commit.
“AI Summary”: Free and PRO, with daily allowances (lower on Free). Needs subtitles, internet and a Udemie Cloud sign-in. The lecture’s transcript is sent to Udemie’s servers and an AI provider.

It needs readable text (scanned PDFs may not work), internet and a Udemie Cloud sign-in, and it sends text from the document to Udemie and an AI provider. You check each quiz answer or flashcard before it joins your Daily review.

Questions and answers
How do I start?
Download Udemie for Windows or Linux and open it. Sign in to Udemy, Coursera or LinkedIn Learning on the platform’s own page, choose a course, choose the lectures and download. The Free plan needs no payment card.
Is it legal to download my courses with Udemie?
Udemie only reaches the courses your own account can open, and it does not bypass payment, enrolment or DRM protection. Whether keeping an offline copy is allowed is set by each course platform’s terms, which you accepted with your account; Udemie’s terms ask you to respect them. Udemie is not affiliated with Udemy, Coursera or LinkedIn Learning.
Can Udemie download courses I have not bought?
No. You sign in with your own account and Udemie shows the courses that account can open. It does not enrol you, pay for you or unlock anything.
What happens with DRM-protected lectures?
Udemie does not try to break DRM. Protected lectures are skipped, and the rest of the course downloads normally. On Udemy, they are marked in the course outline before you download. A protected lecture still plays on the platform’s website.
Which course platforms are supported?
Udemy (personal accounts and Udemy Business, including single sign-on), Coursera and LinkedIn Learning. Coursera courses are listed from your account and downloaded course by course. LinkedIn Learning courses are added from their links.
Does Udemie work on Mac, iPhone or Android?
No. Udemie is a desktop app for Windows (Microsoft Store or direct installer) and Linux (Snap Store or .deb package).
Does it work without internet?
Yes, for everything already downloaded: the player, subtitles, files, notes, highlights, Daily review, Smart Recap and the Learning Path work offline. Search works offline after a one-time model download of about 135 MB. Signing in, new downloads and AI features need internet.
What stays on my computer, and what is sent to a server?
Your courses, notes, highlights, cards, saved words and the search index stay on your computer. AI features (summaries, chat, Answer from my lessons, translation, online word meanings, the PDF Study assistant and AI ordering of the Learning Path) send the text they need to Udemie’s servers and an AI provider; the table on this page lists what each one sends. Learning checkpoints, audio recaps and Knowledge Map creation send the text of the lessons you select. Automatic summaries are on by default once you sign in to Udemie Cloud; you can turn them off in Settings.
Does Udemie see my platform password?
No. You sign in on the platform’s own page inside Udemie. Udemie keeps only the session, on your computer.
Do I need an account?
You need your own account on Udemy, Coursera or LinkedIn Learning, with the courses you want to download. Udemie itself needs no payment card and no Udemie account to download on the Free plan. A free Udemie Cloud account (your email address and a code) is needed only for features that use Udemie’s servers, such as the AI features.
What is free?
Each calendar month you can start 3 new courses and download the first chapters of each, at full speed and up to 720p. The course page shows what is free before you start. Notes, highlights, Daily review and the other local study tools have no limit. Search covers 3 courses you choose, Chat with the course works in 2 courses, and AI features have lower allowances. Current numbers are on the Pricing page.
What does PRO add?
Every video of every course you have access to (DRM-protected lectures are always skipped), the best quality the course offers, search across every course and everything you saved, Answer from my lessons, and higher AI allowances. PRO is monthly, yearly, Lifetime (one payment) or a 7-day pass sold in the app.
On how many computers can I use my licence?
A PRO subscription (monthly or yearly) covers 2 devices. Lifetime covers 1 device. Once a month you can move the licence to the computer you are using, in Settings under “Plan & license” (“Use this device only”).
What happens when my subscription ends?
The courses you downloaded are files on your computer, and your notes, highlights and cards stay on your computer. The PRO features stop and the Free plan applies.
Can I cancel? Is there a refund?
You can cancel a monthly or yearly plan at any time in the app; it stops at the end of the period already paid. Cancelling does not by itself refund a completed payment; for a payment question, contact support@udemie.study.
Does my PRO licence work offline?
Yes. A PRO licence keeps working offline for 30 days between renewals; Lifetime has no deadline.
In which languages is Udemie available?
The app is in English, French, Spanish and Turkish. Subtitles can be saved in 16 languages, and AI translation of subtitles offers English, French, Spanish, Portuguese, German, Italian, Japanese and Korean.
Can I export my notes and cards?
Yes. Notes export as Markdown or CSV. Cards, highlights, notes and saved words export to Anki as an .apkg file or directly with AnkiConnect, each with a link back to the lesson and time.
Does Udemie sync between my computers?
No. Your library and study data are stored on the computer where you use them. You can export cards and review history to a study file and import it on another computer.
Is the AI unlimited?
No. Each AI feature has a daily or monthly allowance, lower on Free and higher on PRO, and the app shows what is left in “Cloud usage”. Local tools such as notes, highlights, Daily review and search have no allowance.
