About SEO Check Tools

SEO Check Tools is a free YouTube analytics and SEO platform for content creators. 21 tools across the full creator workflow — Research, Optimize, Publish, Analyze. The flagship surfaces are measurement-first: a composite Visibility Score across CTR, metadata, niche headroom, and growth trajectory; a whole-channel Channel Audit with AI-extracted recurring issues; a single-video Video Audit with one-click AI-Fix orchestration that rewrites every weak metadata field at once; an Outlier Finder that surfaces breakthrough videos against the channel median; and weekly historical Visibility Score tracking on any channel you mark to follow. On top of that, 14 single-purpose AI generators and browser utilities for titles, tags, hashtags, thumbnails, chapters, descriptions, and earnings.

We built it because the alternatives don't fit how most creators actually work. The big paid suites (TubeBuddy, VidIQ, TubeRanker) charge $19-49/month for tools you only need before each upload, and gate the most valuable analytical features behind paywalls. The free alternatives are 10-year-old ad-stuffed sites with broken interfaces. We built the measurement-instrument layer (Visibility Score, Channel Audit, Outlier Finder, historical tracking) free, alongside a well-designed generator collection that doesn't feel like 2010.

The principles

100% free, no signup: Every tool is free. There is no account creation, no email capture, no "free trial" that turns into a subscription. The AI-powered tools have a daily fair-use limit (15 generations per tool per IP) to keep compute costs affordable — that's it.
AI where it counts: We use Anthropic's Claude Haiku for tasks where AI genuinely produces better results: title and description brainstorming, tag and idea generation, the orchestrated Fix-with-AI button that rewrites every weak metadata field after the audit in one call, the differential pattern analysis in Competitor and Outlier Finder, the recurring-issue extraction in Channel Audit, and the one-sentence positioning summary on the Visibility Score. Browser-side utilities (thumb download, embed code, chapter format, Title Score Checker, Thumbnail Preview) stay browser-side — no LLM cost, no API delay.
Privacy by default: No analytics scripts that follow you across the web. No cookies beyond what bot protection strictly requires. IPs are held in memory only and discarded each UTC day. Prompts and outputs are not stored.
No tool-gating: Features paid suites charge for — like extracting tags from a competitor's video — are simply free here. The only reason they can charge is that nobody bothered to make a free version that doesn't suck.

How we keep it free

Hosting costs are small (Vercel + Cloudflare + Upstash all on free tiers). The biggest expense is the AI compute — about $0.003 per generation, capped at $5/day platform-wide. In the future the site may host lightweight contextual ads via Google AdSense and a small number of affiliate links to genuinely useful paid tools (Ahrefs, TubeBuddy, Canva). If and when that happens, it will be clearly disclosed and easy to spot.

The tech stack

Next.js 14 on Vercel. Anthropic Claude Haiku for AI generations. Upstash Redis for rate limiting and caching. Cloudflare Turnstile for bot protection. Vercel Analytics for cookieless page-view measurement. That's the whole list of services involved when you use the site.
