The toolkit

Everything you check before you hit publish

Each tool shows its price in diamonds up front, and returns the diamonds if it fails.

Keyword research

Type a keyword and see the top 20 videos ranking for it, how fast they gain views, how big their channels are, and related keywords they share.

5 per search

Tag lookup

Paste any video link to see its tags, title and stats. Copy every tag in one tap.

2 per video

AI titles, descriptions & tags

Five title options, a full description with timestamps, a tag list that fits YouTube’s 500-character limit, hashtags or fresh video ideas.

10 per generation

SEO score

Check a draft before you publish: keyword in the title, lengths, tag count and hashtags, with a fix for each problem. Works offline.

Free

Trending ideas

What’s popular in your country and category right now, with outliers flagged: videos doing far better than their channel usually does.

Diamonds

Pay for what you use

Buy diamonds through Google Play and spend them on tools and unlocks. Prices in your currency are shown by Google Play in the app.

Scores are estimates, and we say so

YouTube doesn’t publish how often a keyword is searched. Instead of inventing a number, Tube Gain scores competition and opportunity from the videos that actually rank: their views, age, speed and channel size.

Questions

Straight answers

Anything else: unte2003@gmail.com

Is Tube Gain made by YouTube?

No. Tube Gain is an independent app for YouTube creators. It reads public data through the official YouTube API and is not affiliated with YouTube or Google.

Does it need my YouTube password or account?

No. Nothing in the current version asks for access to your YouTube or Google account. It only looks at public videos and channels.

Why don’t you show search volume?

YouTube doesn’t publish search volumes, and apps that claim exact numbers are guessing. Tube Gain shows competition and opportunity scores worked out from the videos that actually rank, and labels them as estimates.

Is there a subscription?

No. You buy diamonds when you need them and spend them per use. Unlocks like tag packs, themes and the competitor tracker are yours for good.

What happens if a lookup fails?

Your diamonds come back automatically. If YouTube or the AI service is down, or a video turns out to be private, you are not charged.

I reinstalled the app. Where are my diamonds?

Balances are stored on our server under your account. Until account restore is available, write to unte2003@gmail.com with the account ID shown in Settings and we will help.

Your next video, better prepared.
