What's inside

Everything you need. Nothing you don't.

A focused toolkit for getting your video published with strong SEO and a thumbnail that earns the click.

AI thumbnails

Three 1280×720 thumbnails per run, drawn by the top image models — Google Gemini (Nano Banana) and OpenAI GPT Image. No prompt to write: the AI takes the story from your video.

SEO title

An optimized YouTube title that keeps your hook intact but front-loads the keywords people in your niche actually search for.

SEO description

A full-length, keyword-rich description written around the topics in your video — copy-paste ready for YouTube Studio.

SEO tags

A relevant tag set built from your video's transcript and the queries that match the topic — ready to paste into the tags field.

Chapters

Clickable YouTube chapters with real timecodes, generated from the video's content — paste them into the description.

Any source

Drop a YouTube URL, upload a raw video or audio file, or send just a subtitle file (.srt or .vtt). BYSO works with all of them.

8 languages

SEO and thumbnail text in 8 languages: English, Spanish, Portuguese, Russian, French, Ukrainian, Polish and Hindi. The site interface is available in 6.

Vertical 9:16

Vertical thumbnails for Shorts, Reels and TikTok — not just 16:9. Detected automatically from the video.

Your face on the cover

Upload your photo — AI places you (or the right people) on the thumbnail, with your real, recognizable face.

FAQ

Questions, answered.

A full generation produces one optimized title, one full description, a tag set, and three distinct thumbnail variants (1280×720 PNG). An SEO-only generation produces the title, description, and tag set without the thumbnails — useful for videos where you already have a thumbnail.
Four sources: a YouTube URL, a video file upload, an audio file upload, or a subtitle file (.srt or .vtt). If you only have a transcript, the subtitle path is the fastest — no transcription needed on our end.
Results — titles, description, tags and thumbnail text — come in 8 languages: English, Spanish, Portuguese, Russian, French, Ukrainian, Polish and Hindi. You pick the output language in the generation form. The site interface is available in 6 languages (all but Polish and Hindi) and is switched in the top-right corner.
No. BYSO is pay-as-you-go. You top up a USD balance once and spend it whenever you generate. A full generation costs $0.50; SEO-only is $0.10. If you don't generate, you don't pay.
10 free credits on signup, no card required — enough for 2 generations with thumbnails or 10 SEO-only. After that it's pay-as-you-go: $0.50 per full, $0.10 per SEO. If you don't generate, you don't pay.
Yes. Each of the three thumbnail variants is downloadable as a 1280×720 PNG, sized exactly for YouTube. There's no watermark, no resizing step — you can upload the file directly in YouTube Studio.
With a YouTube link the price is the same at any length: 5 credits for a full generation, 1 for SEO-only. Uploaded files we transcribe ourselves, so files longer than 10 minutes add 1 credit for every further started 10 minutes — for example, 35 minutes is 8 credits with thumbnails or 4 for SEO-only, an hour is 10 or 6. You see the price on the button before you start. The cheapest way is to upload the video to YouTube (Unlisted is fine), wait until YouTube makes captions, and paste the link. If a generation fails, no credits are charged; with long files, up to 3 such failed attempts per 24 hours are allowed (no limit if you have ever topped up).

Your next video deserves the click.

Free to start. No card. 10 credits on the house — that's 2 generations with thumbnails.
