🇺🇦 Читати українською: TubeBuddy чи VidAI для перекладу YouTube
TubeBuddy is one of the best-known YouTube toolkits, and it has a translation feature. VidAI is a translation-first extension. If you're choosing between them for translating your videos into other languages, this is the comparison we'd want to read ourselves — including the parts where TubeBuddy is the better buy.
Short version: TubeBuddy's AutoTranslate exists only on its top plan, handles titles, descriptions and tags one video and one language at a time, and every extra channel needs another license. VidAI translates titles, descriptions, hashtags and subtitles into 90+ languages in one click, publishes them as official YouTube localizations, and includes 2–50 channels in its plans. For everything that isn't translation — keyword research, A/B thumbnails, bulk SEO tooling — TubeBuddy is the broader suite.
What each tool actually translates
| TubeBuddy AutoTranslate | VidAI | |
|---|---|---|
| Titles | ✅ | ✅ |
| Descriptions | ✅ | ✅ |
| Tags / hashtags | ✅ tags | ✅ hashtags (translated or preserved — your choice) |
| Subtitles | ❌ | ✅ (checks and publishes your original captions first if needed) |
| Languages | 40+ | 90+ incl. regional variants (Latin-American Spanish, Brazilian Portuguese, Traditional Chinese…) |
| Workflow | Inside YouTube Studio's Add language dialog, per video, per language | One click per video: pick languages (presets like Top 20 most spoken), done — runs in the background |
| Publishing | You confirm in Studio | Published to YouTube automatically (Fast API mode) or automated in your Studio tab (Browser mode) |
| Plan needed | Legend only | Every plan incl. Free |
Sources: TubeBuddy's AutoTranslate support article and tool page state Legend-only access, titles/descriptions/tags and 40+ languages (support.tubebuddy.com, tubebuddy.com/tools/auto-translator). VidAI's scope is documented in the one-click translation guide.
The workflow difference matters more than it sounds. TubeBuddy's tool lives inside YouTube's own Subtitles → Add language → Title and description flow — so for 20 languages you open that dialog 20 times per video. VidAI treats the 20 languages as one job: one click, a progress bar, and the Translations tab in Studio fills up with Published.
Pricing, side by side
TubeBuddy (per LensPOV's April 2026 plan breakdown): Pro $7.99/mo, Star $15.99/mo, Legend $39.99/mo — or $4.99 / $11.99 / $29.99 per month billed annually. AutoTranslate is Legend only. All plans cover one channel; additional channels need separate licenses, with a 25% discount available on Legend licenses only.
VidAI (per vidai.help/plans, EUR, yearly billing 20% off):
| Plan | Monthly | Credits / month | Channels included |
|---|---|---|---|
| Free | €0 | 250 | 1 |
| Entry | €2.99 | 1,000 | 2 |
| Basic | €5.99 | 2,500 | 5 |
| Pro | €11.99 | 5,000 | 10 |
| Max | €19.99 | 10,000 | 20 |
| Ultra | €49.99 | 25,000 | 50 |
VidAI charges in credits, so here is the arithmetic with nothing hidden: 1 credit translates 300 characters of description into one language, plus 1 credit per title. A 1,200-character description into one language costs 5 credits; into 20 languages, 100 credits. Three things reduce that further:
- Loyalty bonus: monthly subscribers get +20% credits for every month they stay, up to double their plan after 6 months (cancelling resets it; yearly plans are already discounted instead).
- Saver mode: choose Saver in the translate window and the job costs half the credits — translation leans mostly on AI instead of the premium machine-translation step, so it's a bit slower on big jobs and phrasing is a touch more AI-flavoured. Your call per job.
- Extra credits never expire and get cheaper with your plan: €9.99 per 1,000 on Free, €2.99 on Entry, €2.40 on Basic/Pro, €2.00 on Max/Ultra.
The scenario that decides it: more than one channel
Take a realistic creator: 3 channels, 20 videos a month in total, 1,200-character descriptions, translated into 20 languages.
TubeBuddy: AutoTranslate needs Legend, and each channel needs its own license. Month-to-month that's $39.99 + 2 × $29.99 (the 25% multi-channel discount) ≈ $100/month; billed annually ≈ $75/month. Then 20 videos × 20 languages = 400 trips through Studio's Add language dialog. No subtitles.
VidAI: 20 videos × 100 credits = 2,000 credits/month. Basic at €5.99 covers it — 2,500 credits and 5 channels included, two to spare. After six months of loyalty the same plan gives 5,000 credits; with Saver mode the job needs 1,000. Subtitles included in the same click.
That's not a rounding difference. It's the difference between a tool priced per channel and one priced per work done.
Where TubeBuddy is the better choice
Honesty cuts both ways. TubeBuddy is a full channel toolkit: keyword explorer, competitor tracking, A/B testing for thumbnails and titles, bulk edits of cards and end screens, comment filters, and years of polish. If translation is a side task and you want one subscription for SEO research and channel management, Legend earns its price on those features — AutoTranslate is a bonus on top.
VidAI does have AI titles, descriptions, tags, chapters and a free thumbnail competitor tester, but it doesn't try to be a keyword-research or analytics suite. It tries to make your existing videos findable in 90 languages with the least possible effort — and to make that affordable for creators who run several channels.
Three questions to ask yourself
- Is translation the main reason you're paying? If yes, paying $30–40/month per channel for a Legend tier to unlock it is hard to justify against €2.99–€11.99 for 2–10 channels.
- How many channels? One channel narrows the gap; two or more widens it fast, because TubeBuddy multiplies and VidAI doesn't.
- Do you need subtitles translated too? Only one of the two does it.
FAQ
Does TubeBuddy translate subtitles? Its AutoTranslate tool covers titles, descriptions and tags, per TubeBuddy's documentation. VidAI translates and publishes subtitle tracks as well.
Can I use both? Yes — they don't conflict. Many creators keep TubeBuddy for research and use VidAI for the translation job itself.
Do I need a paid VidAI plan to try it? No. The Free plan includes 250 credits a month — enough to translate a few videos into a handful of languages and see the Published column fill up in Studio.
Is VidAI's Fast API mode safe? It publishes through the official YouTube Data API with your explicit OAuth consent, the same mechanism TubeBuddy and vidIQ use. You can revoke it any time in your Google account.
Will translations change my original title or description? No. YouTube localizations are additions shown to viewers in their language; the original never moves.
