Translation

This is the single highest-leverage thing most creators never do. One click translates your title, description and subtitles into language after language — fast, reliable, running in the background while you do something else. The video doesn't change. Who can find it does.

Why this matters more than it sounds

Here's the thing creators miss: your video is often already universal — only the words around it aren't. YouTube decides who to show a video to largely from its title and description. If those are only in English, YouTube mostly shows it to English speakers — even when the video itself would delight someone in Brazil, Japan or Germany exactly as much.

Translate the title and description and that same upload suddenly competes in search and recommendations across every language you added. You didn't re-record anything. You didn't make a new video. You turned one audience into many — with one click.

Best of all on videos that already cross borders

Some videos barely need language to be enjoyed — the language is only the doorway to finding them. Those are where translation is almost pure upside:

Titles & descriptions — this is the core

If you do only one thing from this whole guide, do this. Translating your title and description is the part that actually grows the channel. Subtitles help people watch; the title and description are what make YouTube show them the video at all — search and recommendations are language-aware, so an English-only title is invisible to a Spanish viewer no matter how good the video is.

VidAI translates the title and description for every language you pick and publishes them as YouTube's official localized metadata — the same field YouTube uses to decide who sees the video. One video, suddenly competing for views in a dozen languages. That's the whole game, and it's one button.

Two ways VidAI runs it — Server (fast) vs Browser

VidAI can translate your title & description in two different ways. They reach the same result; the difference is speed and reliability. Use Server mode whenever you can.

Reach for Browser mode only when Server mode isn't available for what you're doing. For titles and descriptions, Server mode is the default and the right choice almost always.

Subtitles: VidAI automates YouTube's own translation

Subtitle translation works differently, and it's important to understand why. The subtitle translation itself is done by YouTube, not by VidAI. YouTube already auto-translates subtitles — but only one language at a time, click by click, which nobody has the patience to do for 50 languages.

So for subtitles VidAI doesn't translate — it automates: it drives YouTube's subtitle screen and clicks through every language for you, turning a 50-click chore into one action. Two consequences worth knowing:

Why Browser mode can be finicky: YouTube has two different pages

YouTube doesn't show everyone the same translation screen. There's an older page (labelled "Video subtitles") and a newer one (labelled "Languages", with Audio / Subtitles / Title & description / Thumbnail columns). Which one you get depends on your channel's dubbing settings — and YouTube can show different versions for different channels you manage. It's entirely on YouTube's side; you didn't do anything.

VidAI supports both. You may notice a small V2 / V3 badge on the VidAI toolbar — that's just VidAI telling you which version of YouTube's page it detected and adapted to. Here's what actually matters to you:

Settings — tune how it translates

Click ⚙ Settings on the VidAI toolbar. There are two parts: which languages to target, and how the translation behaves.

Which languages

Use a quick preset — Top 10 or Top 20 most-spoken, or Select all — or flip individual languages on and off. Each one shows an estimated audience size so you can prioritise. This set becomes your default for every video; you can also manage it at vidai.help/selected_languages.

How it behaves

Title translation engine lets you trade speed for polish: Standard (fast and reliable), AI Translation (smarter, more natural phrasing), or Pro Machine (the most accurate — available on higher plans).

How to use it — step by step

1. Generate strong metadata first

   On the video, create a great title and description before translating. This is the single biggest lever — translate the good version.

2. Open the video's Subtitles / Languages page in YouTube Studio

   Left sidebar → Subtitles (older layout) or Languages (newer layout). Either way, VidAI's purple toolbar appears across the top with the buttons below.

3. Choose languages in ⚙ Settings

   Click Settings on the VidAI toolbar to pick which languages to target. Start with the big ones for your niche (Spanish, Portuguese, Hindi, Arabic, Japanese reach enormous audiences), widen later. You can also manage this on vidai.help/settings.

4. Click 🌐 Auto Titles & Descriptions

   This is the important one — the Server-mode, fast, reliable path. One click translates and publishes your title & description across every chosen language, in the background. Close the tab; it finishes on its own.

5. Optionally click 🔀 Subtitles

   Want translated subtitles too? Click Subtitles to have VidAI automate YouTube's per-language subtitle translation for you. Browser-mode, so leave it running and re-run if it stalls.

6. Manage with 🗑 Remove all

   Changed your mind, or want to redo from scratch? Remove all clears the translated languages so you can start clean.

7. Track it

   Server-mode jobs are listed at My translation jobs with status, languages and exact credits used. For Browser mode, make sure the channel is in My connected channels first.

Your translation job page — review, fix & re-publish

Every Server-mode translation gets its own page — open one from My translation jobs. It's a real working surface, not just a status screen, and the link is shareable: anyone you send it to can see the video, the original and translated titles & descriptions and the status, while the editing tools, AI tools and technical details stay private to you when you're signed in.

Review

Live status and a progress bar while it runs (the page refreshes itself), total credits used, and a clear error message with a Retry button if anything fails. Every language is a collapsible card — sort them A–Z or by audience size, and expand or collapse them all at once.

Edit the results

Publish your changes back

Edited something? Republish pushes your updated titles & descriptions back onto the video on YouTube. Retry re-runs a job that failed, and if you used regional sub-languages those can be retried on their own. There's no delete here by design — re-run or republish instead.
