The first 5-15 seconds of your video — only the cold-open / hook segment, not the whole script. Pick one of 8 hook formats (provocative question, surprising stat, personal story, bold promise, contrarian take, curiosity gap, problem/pain, in-medias-res cold-open), set length (5/10/15 sec), tone, and channel niche. Output: 3 variants with optional delivery notes (camera direction, b-roll cue, music swell) so your editor knows how to cut each one.
YouTube's audience-retention graph drops most steeply between seconds 0-15. If you lose viewers there, the algorithm de-ranks the video. Studies (Mr Beast, Paddy Galloway, Veritasium teardowns) all converge on the same finding: the first sentence has to grab attention in under 3 seconds — no 'hey guys welcome back to the channel'. The Intro Generator is built around that specific 0-15s window.
Yes — Qwen 3 30B on our GPUs. Three 10-second variants with delivery notes cost ~250 tokens. Free accounts get 10,000 signup tokens, enough for 30+ runs. Premium Claude Sonnet / GPT-5 produce sharper hooks at 5-10x the cost — worth it for monetized channels where +5% CTR pays back instantly.
TubeBuddy ($7-49/month) and VidIQ ($7.50-79/month) focus on title + thumbnail SEO, not script-writing. Veed.io ($25/month) and Invideo ($30/month) make ANIMATED intro stings — short logo reveals, not the spoken hook. Free.ai writes the spoken script; pair with Veed/Invideo if you also need a visual sting. Different problem.
Eight hook formats, each with a dedicated system prompt: (1) Provocative question — opens with a question the video answers; (2) Surprising stat — leads with a number; (3) Personal story — drops viewer mid-anecdote; (4) Bold promise — names the outcome; (5) Contrarian take — calls out conventional wisdom; (6) Curiosity gap — teases without revealing; (7) Problem / pain — names the viewer's frustration; (8) In-medias-res — cold-opens like a movie.
No — the system prompt explicitly bans 'hey guys welcome back to the channel', 'smash that like button', 'without further ado', and 'in today's video we're going to talk about'. If a variant slips, regenerate; if it happens twice, file a report (we tighten the prompt). Modern retention requires hook-first writing, not housekeeping.
Per-variant production cues: camera direction (close-up / wide / cut), suggested b-roll, music swell timing. Toggleable. Useful if you (or your editor) wants the model to pre-think the visual cut alongside the script. Skip them if you cut your own videos and find the cues noisy.
Same format — that's the design. The 3 variants A/B/C let you A/B test execution within ONE format. To compare formats, run YouTube Intro Generator twice with different hook selections. YouTube Studio's Test & Compare feature lets you serve different intros to different viewers and pick the winner.
No — first run is free, no email, no credit card. Sign up for 10,000 tokens, generation history, premium model access, and 7-day share links.
Use the 5-second length and 'curiosity gap' or 'surprising stat' format — both work best for Shorts. For Shorts-specific scripts (with TikTok-style pacing), use /youtube/shorts-script/ instead — it generates the FULL 30-60s script, not just the hook.
Yes — all 99 Free.ai languages. Channel niche, topic, and tone all generate in your input language. Hook conventions translate well — questions, stats, and curiosity gaps are universal across languages, though the cliché list is English-specific (the system prompt loosens for other languages).
Yes — POST to /v1/chat/ with the intro-generator system prompt (inspect template source for the exact prompt). Useful for faceless-channel pipelines or agency tooling that batch-generates intros for a creator slate. Bearer auth, monthly limits. Docs at /api/.
