Audit Excel workbooks before you trust, send, or deliver them. Detect formula, structure, data-quality, hidden-content, dependency, validation, and consistency risks with traceable evidence — without modifying the original file.
Prepare CSV, TSV, Excel and JSONL files before sharing with AI, clients or vendors. Preview candidate matches, redact, use consistent pseudonyms or remove fields, then export separate copies with an audit report. Local processing; no API required. English edition.
Stop API keys and private keys from reaching git, screenshots, or shared logs.
A security health check for small businesses that explains every problem in plain language and shows how to fix it. Audits your computers (firewall, antivirus, updates, encryption, admin accounts, remote desktop), your website (HTTPS, certificate, headers, exposed .git/.env files), email spoofing protection (SPF, DKIM, DMARC), your code (leaked keys, debug mode, vulnerable packages) and staff habits. Scored report plus fix scripts that ask before every change.
Enter your holdings and share counts to get a diagnostic table, graphs, and a shareable card: risk share vs. weight (who's moving your account), hidden overlap that adds ETF holdings to your direct positions, a correlation heatmap, sector and currency concentration, effective number of holdings, and worst 3-year drawdown at today's counts. Korean and US stocks and ETFs. A past-price diagnostic, not a recommendation of tickers or weights; you are responsible for your own decisions. No API key.
Build auditable Excel financial models with live formulas, sourced inputs, automated checks, and sensitivity analysis—all generated headlessly with openpyxl.
Local CSV, TSV, XLSX and JSONL redaction with Traditional Chinese instructions and reports. Preview first, then explicitly apply field removal, redaction or stable batch pseudonyms. No API required. Same engine as the English edition; choose one.
Find what your PDF leaks or breaks before you hit send - unapplied redactions, author names, comments, edit history, attachments, local links and missing fonts, each with evidence and a fix.
Runs five integrity checks on every slide before output — one message per slide, title-body alignment, number preservation, source citation for every data point, and design spec compliance — blocking any slide where data has been smoothed, sources are missing, or the title contradicts the body.
