About Omna

Omna — Stop the Token Tax. Build a Privacy Wall. You're overpaying for AI. Every time you paste a file, a spreadsheet, or a long document into Claude or ChatGPT, you're sending thousands of tokens the AI doesn't need — and paying for every one of them. Omna fixes that before the data leaves your browser. THE TOKEN TAX IS REAL A $50 query becomes $0.05 when you send 100 rows instead of 100,000. Omna's local Rust engine finds the exact context your AI needs — the right rows, the right fields, the right data — and strips everything else. Your AI gets a surgical input. You get a precise answer at a fraction of the cost. YOUR PRIVATE DATA STAYS PRIVATE Names, emails, phone numbers, government IDs, financial data — all masked locally before anything touches an AI server. The AI answers with placeholders like [PERSON_1]. Your real data never leaves your device. Shield mode decodes the reply so you read natural language, not tokens. HOW IT WORKS • Type or paste into Claude, ChatGPT, Gemini, Perplexity, or DeepSeek • Omna detects sensitive data instantly using a local WebAssembly engine • PII (sensitive data) is masked before sending — the AI never sees the real values • Attach a Word doc or PDF — Omna scans it, masks it or alerts you before you send • Token counter shows exactly how much you're saving in real time • Shield mode decodes the AI's reply so you read natural language, not [PERSON_1] WHAT THE METRICS MEAN Fields Masked — how many pieces of sensitive data Omna has hidden Uploads Protected — how many file attachments have been scanned before sending Tokens Saved — estimated tokens removed by sending only what the AI needs WORKS ON Claude.ai · ChatGPT · Gemini · Perplexity · DeepSeek FULLY LOCAL. ZERO CLOUD. Omna runs entirely in your browser using a Rust-powered WebAssembly engine. No data is sent to Omna servers. No account required. Everything happens on your device, in milliseconds.
