Frequently Asked Questions

No API key required. Sign in with Google and AI features are powered automatically by our server. No setup needed.
All processing happens at 127.0.0.1 (local). Only your query text is sent to Groq/OpenAI for AI responses — your files, emails, and system data never leave your PC.
Personal-use price comparison and information retrieval is generally permitted. Commercial bulk scraping or login bypassing should comply with each site's Terms of Service.
Windows 10 or later is recommended. PC control features (PowerShell, WMI, Outlook COM) are Windows-exclusive. Mac supports basic AI chat only.
Updates are delivered via GitHub Releases using go-selfupdate. On launch, NEXUS checks for a new version and prompts you — one click updates to the latest.
Full automation (send, reply, calendar sync) requires Outlook installed. Naver, Daum, and Kakao Mail support read & summary only via IMAP — auto-send is Outlook-only.
Yes. In the Small Business persona, enter any Korean business number and NEXUS queries the National Tax Service API in real time — confirming active/suspended/closed status and surfacing relevant support programs. International business numbers are not yet supported; we recommend checking your local tax authority's official portal.
The Corporate persona tracks monthly VAT, corporate tax, and payroll insurance deadlines, detects electronic invoice discrepancies automatically, and helps draft or review contracts. It uses sonar-pro deep search to pull the latest tax authority notices and compliance updates.
