Nox changelog — product milestones

Nox ships continuously; this changelog groups the notable user-facing milestones by month rather than listing every deploy. Dates reflect when a capability became broadly available in the app.

July 2026 — Expanded safety layer, region-aware emergencies & trust hub

• Named Nox's medical-safety system "Leo" — the same deterministic red-flag screening and AI backstop, now with a name you'll see across the app and an intro card the first time you use it.
• Expanded the deterministic red-flag detector to over 100 rules across 70+ acute categories — from cardiac, stroke, and severe breathing difficulty to trauma, pregnancy, pediatric, environmental, toxicology, and mental-health crises — re-measured on a maintained labeled test set (numbers published on the Accuracy page).
• Added an AI safety backstop: when the pattern rules find nothing, a lightweight AI classifier re-reads recent messages to catch dangerous descriptions worded in slang, another language, or indirectly, and surfaces the same seek-care guidance. It only ever adds a safety note, and is evaluated on its own separate test set (kept out of the published detector metrics).
• Made Leo's strictness your choice: a free control right in the chat box lets you pick how far screening goes — Relaxed, Standard, or Strict — while emergency screening always runs at every level (no level turns it off), and Agent and voice conversations always use the strictest setting.
• Region-aware emergency guidance: set your region in Settings and red-flag banners show the correct local emergency number, falling back to universal numbers (911 / 999 / 112) when the region is unknown.
• New public pages: how Nox works, ring-data demo (labeled sample data), illustrative scenarios, consolidated FAQ, accuracy & testing report, privacy whitepaper, reliability report, support & refunds, changelog, and roadmap.
• Accuracy page now renders the committed, machine-generated red-flag detector metrics — the same numbers as the Trust & Transparency page.
• Search-engine and AI-crawler visibility: every new page is prerendered with structured data, mirrored as markdown, and listed in sitemap.xml and llms.txt.

June 2026 — Transparency, connected apps & search visibility

• Trust & Transparency page with published red-flag detector recall and false-positive metrics, governance record, and data-source licensing.
• Nox's App: confirm-first integrations with Google Calendar, Google Docs, Google Drive, and Todoist — Nox only creates new items and always asks before acting.
• Site-wide SEO/GEO work: prerendered public pages, sitemap, llms.txt, markdown mirrors for AI crawlers, and IndexNow submission on every publish.

May 2026 — Voice calls, memory & incognito

• Live voice calls with Nox (real-time speech in many languages), with the same safety layer applied to voice conversations.
• Memory: Nox remembers durable facts you share (allergies, conditions) with full review-and-delete control in Settings.
• Incognito mode: conversations that are never saved.

April 2026 — Deep research & usage allowances

• Nox Agent: deep research with live web sources and cited, openable resource cards.
• Usage allowances across all plans — automatic refresh on every plan, and extra-usage purchases that never expire.
• Enterprise tier for teams — custom usage, shared workspaces, and custom modes.

March 2026 — The safety foundation

• Deterministic red-flag safety layer that screens every message before the AI answers, with an evaluated, committed metrics report.
• Health library and medicine lookup across 100,000+ FDA-listed medicines.
• Photo & label analysis, inline charts, image generation, Analyze My Day, and Daily Check-in.
