AI-generated titles, descriptions, tags and hashtags for YouTube, Shorts and Instagram — built for today's ranking algorithms.
Enter a topic or draft title. The more specific you are, the better the AI can pick keywords for the YouTube algorithm. You can also dictate by voice.
Choose your audience: RU or EN. Add a niche — “gaming”, “finance”, “travel” — for more targeted tags.
Gemini AI generates titles, a description, tags and hashtags tailored separately to YouTube long-form, Shorts and Instagram Reels.

YouTube is the world's second-largest search engine after Google. Over 500 hours of video are uploaded every day, and without proper SEO your video simply gets lost among millions of others. The right title, description, tags and hashtags can boost CTR 2-3x and help the algorithm understand what your video is about. Our tool generates the complete SEO pack with Gemini AI, tuned to YouTube's latest ranking algorithms for 2026.
The title is the first thing viewers see. Put your main keyword in the first 30 characters, keep it under 60-70 characters, and make people feel something: intrigue, fear, curiosity. Use numbers (“Top 10”, “5 mistakes”), questions (“Why?”, “How?”), conflict and surprising facts. The golden rule: your title should make viewers wonder, “What happens next?”
YouTube cuts off titles longer than 60 characters in search and recommendations. The sweet spot is 50-60 characters. Put your main keyword first — the algorithm gives more weight to the opening words. Our tool automatically writes keyword-rich titles at the right length.
A trigger title sparks an emotional reaction — shock, fear, curiosity or the promise of a payoff. That directly affects CTR (click-through rate), the percentage of people who click your thumbnail. The higher your CTR, the more the algorithm pushes your video. The average CTR on YouTube is 2-10%, while titles with numbers, questions and intrigue hit 8-15%.
The first 150-300 characters of your description show before the “more” link, so they matter most. Put your main keyword in the first sentence. For long videos, write up to 3000 characters with keywords, a CTA (subscribe, like), social links and hashtags. YouTube indexes the description and uses it for ranking.
At least 250 characters; 1000-3000 is ideal for long videos. For Shorts, aim for 300-500 characters; for Instagram, up to 500. Short descriptions (under 100 characters) don't give the algorithm enough to understand the topic.
An empty description or one that just repeats the title, keyword stuffing (the algorithm treats it as manipulation), no CTA, or a description that doesn't match the video. Your description should read naturally and be written for people — not as a list of keywords.
Tags help the algorithm understand what your video is about and show it to the right audience. You get up to 500 characters, comma-separated. Start with exact-match keywords (the topic), then broader ones (the niche), then LSI keywords (synonyms and related terms). Stick to short, high-volume keywords (1-2 words) rather than long phrases.
YouTube caps tags at 500 characters (not words!). 15-25 tags is the sweet spot. Our generator picks tags automatically and shows a character counter, so you always know how much of the 500 you have left.
Tags aren't a major ranking factor, but they help the algorithm understand context and surface your video in “Recommended”. What matters most is audience retention, thumbnail CTR and engagement (likes, comments, subscribers). Still, without tags your video may end up in the wrong category.
YouTube recommends no more than 15 hashtags in the description, and 10 is ideal. The first 3 hashtags show above the video title and are clickable. Use short, high-volume keywords (1-2 words) that are relevant to your video.
Always add #Shorts plus 2-3 topical hashtags to your Shorts title, and up to 10 in the description. Without #Shorts in the title, your video may not make it into the Shorts feed and will lose reach.
Technically up to 30, but 10-15 relevant hashtags work best. Our tool generates 15 hashtags for Instagram — a mix of popular ones (big reach) and niche ones (less competition, higher conversion).
YouTube runs two algorithms: search (ranks by keywords in the title, description and tags) and recommendations (based on retention, CTR and engagement). Key factors: relevance to the query, average view duration, likes/comments/subscriptions after watching, and a consistent upload schedule.
The usual culprits: no keywords in the title/description, missing tags, low thumbnail CTR, poor retention (viewers drop off in the first 30 seconds), a weak thumbnail, and no subtitles. Our tool fixes some of these automatically.
The recommendation algorithm looks at how many viewers watch to the end, how many subscribe afterward, and how many likes and comments the video gets. High CTR + strong retention = recommendations. SEO-optimized metadata gives your video its first push; viewer behavior decides whether YouTube keeps promoting it.
Keep it under 500 characters — punchy and emotional. Add a CTA (“Save this”, “Share”, “Drop a comment”), work keywords in naturally, and use emoji if they fit your style. Our tool writes a ready-to-post caption with hashtags. Want to study the format and captions of top-performing competitor Reels? Download them with Instagram Downloader.
A mix of popular hashtags (100k+ posts, wide reach) and niche ones (1k-50k, less competition). 10-15 is the sweet spot. Every hashtag should be relevant — Instagram cuts reach for irrelevant ones.
