Free.ai YouTube Description Generator writes a structured description up to 5,000 chars with hook paragraph, "What you'll learn" bullets, cleaned timestamp chapters, resource links, subscribe CTA, social links template, disclaimer block (affiliate / sponsor / advice / AI-generated), and ranked hashtags. Live char counter against YouTube's 5,000-char cap. Output pre-fills an editable textarea — tweak and paste into YouTube Studio.
Yes — Qwen 3 30B on our GPUs, about 400-1,000 tokens per description. Free accounts get 10,000 signup tokens. Premium models produce tighter, more keyword-dense descriptions at higher per-video cost but better search ranking.
TubeBuddy's description template tool ($7+/month) requires manual filling. VidIQ description generator ($7.50+/month) focuses on keyword stuffing. Free.ai structures the full 9-section description for free with platform-specific conventions (00:00-first timestamp, hashtag placement, first-150-char SEO zone) baked in.
Yes. Paste timestamps in any format ("1:24 Setup", "01:24 - Setup", "01:24 | Setup") and YouTube Description normalizes them. The first timestamp is auto-set to 00:00 (YouTube's requirement for auto-chapters). 3+ timestamps starting at 00:00 unlock YouTube's mobile chapter UI.
YouTube's search results page and the Description panel show only the first ~150 chars before the "Show more" cutoff. Check "Pack keyword-rich first 150 chars" and YouTube Description weights the opening hook with your primary keywords — improving click-through on Google/YouTube SERPs.
Four: Affiliate disclosure (required by FTC if you monetize links), Sponsored content (YouTube TOS), Not professional advice (legal/medical/financial), and AI-generated content (YouTube 2024 synthetic-content policy). Each uses FTC-friendly wording — customize the [bracketed] placeholders for your situation.
No — first description runs free, no email. Sign up for 10,000 signup tokens and generation history.
Yes — paste them in the Links and Socials fields and YouTube Description threads them into dedicated "🔗 LINKS & RESOURCES" and "🌐 FOLLOW ME" sections. Links are placed beneath timestamps (above-fold-after-scroll), socials at the end above hashtags.
YouTube displays only the first 3 hashtags above the video title, and caps at 15 total. Our default is 3 (maximum SEO impact per tag). Use 10-15 if you want the extra long-tail surface area, 0 if the description is already keyword-dense.
YouTube does not render markdown — **bold** shows up as literal asterisks in the description. Our prompt explicitly strips markdown and uses section headings with emoji icons (🎯 / ⏱️ / 🔗 / ⚠️) which YouTube DOES render for readability.
Yes — all 99 Free.ai languages. Generate descriptions in Spanish, Portuguese, Japanese, etc. Hashtags use Latin-script for international discoverability (YouTube search works language-agnostically on hashtags).
Yes. POST to /v1/chat/ with the YouTube description system prompt. Useful for content-planning apps that pre-generate descriptions for a batch of videos. Bearer auth, monthly limits. Snippets at /api/.
