LLM GPU Benchmark
Speed test your GPU for AI — measure real memory bandwidth and compute with WebGPU, run an actual LLM in your browser to measure true tokens/sec, and see predicted speeds for every popular model on your hardware.
Phishing Email Analyzer
Paste a suspicious email and get an instant phishing risk score — checks for spoofed senders, deceptive links, lookalike domains, urgency tactics, and dangerous attachments. 100% private: nothing is uploaded, with an optional in-browser AI explanation.
PII Redactor
Detect and redact personal and sensitive data — emails, SSNs, credit cards, phone numbers, IPs, API keys — from any text or logs before you share them. Runs 100% in your browser; nothing is uploaded.
Private AI Summarizer
Summarize any text with AI that runs entirely in your browser — paste an article, contract, or report and get bullet points or a TL;DR. Unlike cloud summarizers, your text is never uploaded.
Tokenizer Visualizer — See How LLMs Split Text Into Tokens
Paste any text and watch GPT-4 (cl100k_base) or GPT-4o/o1 (o200k_base) split it into colored token chips, with live token/char/word stats, per-model API cost, and a side-by-side tokenizer comparison. Runs entirely in your browser using the real gpt-tokenizer library — nothing is uploaded.
