Tools that do
one thing well
Free calculators and generators for SEO, GEO, and AI agents. No signup, no upsell wall — everything runs in your browser.
AI / LLM Cost Calculator
Estimate the monthly API cost of an AI agent across Claude, GPT, and Gemini — with prompt-caching savings and a side-by-side model comparison.
Open tool →llms.txt Generator
Build a spec-compliant llms.txt — the Markdown index that tells ChatGPT, Claude, and Perplexity what your site is and which pages matter.
Open tool →Schema Markup Generator
Generate valid JSON-LD for FAQ, Article, Organization, HowTo, and Breadcrumb — the structured-data types Google and AI engines actually use.
Open tool →AI Crawler robots.txt Generator
Allow or block GPTBot, ClaudeBot, PerplexityBot, Google-Extended and more — with a preset that blocks training but keeps you in AI answers.
Open tool →Google SERP Snippet Preview
See how your title and meta description render in Google on desktop and mobile, with real pixel-width truncation warnings — not a character count.
Open tool →GEO Citation Checker Tools
Honest comparison of free and paid tools to check whether ChatGPT, Perplexity, Claude, and Gemini cite your domain — plus the manual method that costs nothing.
Open tool →Reverse Image Search
Search any image across Google Lens, Bing, Yandex, and TinEye in one click — different engines find different matches. Nothing is uploaded; it all runs in your browser.
Open tool →AI Crawler Access Checker
Paste your robots.txt (or enter a domain) and see exactly which AI crawlers — GPTBot, ClaudeBot, PerplexityBot, Google-Extended — can reach your site, with a plain-English verdict.
Open tool →AI Agent ROI Calculator
Enter what a task costs you in people-hours and what an agent would cost to build and run — get monthly savings, 12-month ROI, and the payback period.
Open tool →Reverse Video Search
No engine searches video frame-by-frame — the method that works is to pull one sharp still and search that. Drop a clip, get six frames plus a scrubber, then search on Lens, Bing, Yandex, or TinEye. The video never leaves your browser.
Open tool →Email Without Phone Verification
Which email providers let you sign up with no phone number — 13 of 20 need none at all. Filter by free, privacy-first, alias, or disposable, with the real catch for each.
Open tool →EXIF Viewer & Remover
See the GPS coordinates, camera serial number and timestamp hiding in a photo — then strip them out without re-compressing the image. Nothing is uploaded.
Open tool →llms.txt Validator
Lint your llms.txt against the spec — single H1, blockquote summary, valid link lists — with errors, warnings, and an A–F grade. The validator twin of the generator.
Open tool →Want the whole stack done for you?
These tools cover the pieces. The audit ties them together — technical SEO, schema, and the AI-search layer that gets you cited.
