Our Methodology

How Our Tools Work

AI Free SEO Tools is a browser-first toolkit. Everyday tools open instantly with no signup. Processing may run in your browser, on secure servers, or via AI APIs depending on the job—always with a free path for ordinary use.

• AI tools (Grammar Fixer, AI Detector, AI Humanizer, writers): route through configured providers such as Groq, Google AI (Gemini), OpenAI (GPT), or Anthropic (Claude) when keys are available, with graceful fallbacks so tools stay usable.
• PDF tools: parse and transform documents in secure workflows; uploads are not kept as permanent storage and are auto-deleted within about 5 minutes of processing.
• Image tools: background removal, compress, resize, and convert using client-side and/or model-assisted pipelines designed for product photos and web assets.
• SEO tools: keyword, domain, and on-page helpers that use public web signals and deterministic algorithms. Figures are estimates for free research—not a substitute for enterprise crawl platforms.
• Converters & utilities: format transforms (JSON, CSV, media) that prioritize predictable, local-friendly results when possible.

Data Sources

Where inputs and signals come from:

• Keyword & SEO signals: public APIs, search engine–visible patterns, and heuristic models—not private proprietary crawls sold as guaranteed rankings.
• Domain / authority-style metrics: model-based estimates inspired by common industry approaches (not a paid Moz API seat unless explicitly configured).
• Backlink-style views: public web data and free-tier signals when available; coverage varies by domain.
• AI models: Groq, Google AI (Gemini), OpenAI (GPT), and Anthropic (Claude) when configured for the platform.
• User uploads: processed for the request only; not used to train public models on this free product path.

Accuracy and Limitations

• AI tools: typically about 90–95% accurate for everyday grammar, rewrites, and detection tasks depending on input quality—always review facts, names, and brand voice.
• SEO tools: provide directional estimates for free research—not exact AdWords volumes or live crawl of every URL.
• Image tools: work best on clear, well-lit subjects; complex hair, motion blur, or heavy compression can reduce quality.
• PDF tools: aim to preserve layout, but scanned or highly designed PDFs can vary after conversion or OCR.

Free tools are for everyday workflows. They are not legal, medical, financial, or professional compliance advice.

Privacy and Security

• No account required for standard free tools; we do not store your tool inputs as a permanent product database.
• Uploaded files are processed securely and automatically deleted from our servers within 5 minutes of processing.
• All API calls use encrypted connections (HTTPS/TLS).
• No personal uploads are sold or shared with third parties for advertising on the free product path.
