Generates full YouTube metadata for 9 content types (long-form 8-30min, Shorts under 60s, tutorial / how-to, review / unboxing, podcast / interview, vlog / lifestyle, channel About / banner, community post, playlist description). Outputs 5 title variants under 60 chars, 2,000-3,000-char SEO description with hook in first 2 lines (before 'Show More' cut at ~150 chars), 30 mixed-volume tags, 3-5 hashtags, 3 thumbnail-text options, pinned-comment suggestion, and an 8-second hook script for the video opening.
TubeBuddy is $4.50-49/mo, vidIQ $7.50-79/mo, Morningfame $12-39/mo. All three give keyword research + score + competitive analysis but DON'T write the description copy. ChatGPT (free + $20/mo) writes generic descriptions without YouTube-specific structure (chapters, time-stamps, the first-2-line hook rule, banned-clickbait list). Free.ai is purpose-built — content-type-aware system prompts, 9 distinct prompts (Shorts ≠ long-form ≠ podcast). Free.
Yes — Qwen 3 30B on our GPUs. A long-form metadata package (titles + description + tags + thumbnail + hook + pinned) costs about 1,200 tokens. Free signup gets 10,000 tokens — ~8 sessions. Premium models (Claude Sonnet, GPT-5, DeepSeek R1) write punchier hooks and tighter chapter summaries — worth the swap when you're competing in a crowded niche.
(1) Long-form (8-30 min) — full metadata pack, AVD-driven. (2) Shorts (under 60s) — short title + tiny description + #Shorts + 3-sec hook only. (3) Tutorial — problem-first SEO + chapters + tools/links. (4) Review / unboxing — product name in title + verdict cue + affiliate disclosure placeholder. (5) Podcast / interview — guest name first (their audience subscribes). (6) Vlog — vibe-driven, lighter SEO, music credits. (7) Channel About / banner. (8) Community post — under 600 chars, poll-friendly. (9) Playlist description — what unifies the videos.
Yes — system prompt enforces the 60-char cap with [XX/60 chars] badges next to each variant. Sweet spot per VidIQ + TubeBuddy data is 45-55 chars (longer = truncated in mobile search; shorter = looks sparse). The model front-loads the primary keyword for left-of-screen visibility.
YouTube cuts your description at ~150 chars before the 'Show More' button on mobile. Lines 1-2 must hook the viewer + signal what they will get — they're the only thing 80% of mobile users see. The system prompt enforces this hook structure. Below the cut: full description with chapters, links, about / subscribe.
The first 8 seconds of any YouTube video decide retention — 30% of viewers leave by second 8 if the hook is weak (per YouTube Studio data). The hook script is a word-for-word opening: pattern interrupt + state the value + tease what they'll miss if they leave. NEVER 'Hey guys, welcome back to my channel' — that's the #1 viewer-loss line.
No — banned phrases include 'You WON'T BELIEVE', 'GONE WRONG (POLICE CALLED)', '*EMOTIONAL*', 'MUST WATCH', all-caps spam, excessive emoji. YouTube's algorithm deboosts overpromise clickbait per the 2024 trust update — using these tanks your CTR and watch-time long-term.
Yes but less than they were. Per YouTube's official 2023 statement, tags are mostly used to correct misspellings of your title keyword. The system prompt generates 30 mixed-volume tags (broad / medium / long-tail) anyway because they take 5 seconds to add and have small upside. For Shorts, only 15 tags — Shorts uses fewer signals.
No — first session free. Sign up for 10K tokens, generation history, premium models. ~8 metadata packages per signup grant.
Yes — 9 explicit language presets (English, Spanish, Portuguese, French, German, Japanese, Hindi, Indonesian, Arabic) with regionally appropriate keyword formatting. The 6 biggest YouTube markets outside English are Spanish, Hindi, Portuguese, Indonesian, Japanese, Arabic — picking your real language drastically outperforms English-everywhere.
Yes — POST to /v1/chat/ with the YouTube metadata system prompt (in template source). Useful for video-management SaaS, agency client deliverables, or video-editor plugins auto-generating metadata. Bearer auth, monthly limits. Docs at /api/.
