hYYa ai: Local LLM & Cloud AI

Two engines. One app. Offline or online — you're in control. A local LLM runs offline on your device; hYYa Cloud adds the frontier models when you want them. Most AI apps make you choose between privacy and power. hYYa ai gives you both, and you pick which engine answers every message. BUILT FOR WORK Drawings, contracts and project files are read on your device in hYYa Vault — switch to hYYa Cloud when the job is bigger. • Quantity surveyors: take off a drawing to Excel — lengths, areas and counts from the drawing's own geometry, at the scale you set. • Contracts administrators: review a contract or notice — each finding quotes the clause, with the notice periods worked out for you to check. • Document controllers: ask across a project's documents — specifications, RFIs, transmittals, scans — and every answer cites its page. • Data entry: turn invoices, purchase orders and receipts into Excel rows, each value matched to the page it came from. • Engineers: chat with specifications, reports and DXF drawings on your own machine. hYYa VAULT — THE OFFLINE ENGINE The AI runs on your device. No account needed, and it works fully offline. Your documents and conversations never leave it. • Chat — a local model at full speed, completely offline. Download a model once and it stays on your device; nothing downloads until you choose. • Apple Intelligence — on iPhone, iPad and Mac that support it, chat with Apple's on-device model, with nothing to download. • Daily Brief — every morning, your local AI briefs you on today's meetings, reminders and emails. Written on your device, for your eyes only. • Web Search and Connections — optional, with a free hYYa Cloud sign-in. Only your question goes online; your Local LLM writes the answer. • DataLens — add PDFs, Word files, spreadsheets, presentations or scans and ask questions about them. Answers cite the passage they came from, and scanned pages are read on-device (OCR). • Studio — turn those documents, or any answer, into real deliverables: Excel workbooks with live formulas, Word reports with a cover page and contents, PowerPoint decks with editable charts, and self-contained interactive dashboards. • Quantity Surveyor — a layered CAD file (AutoCAD DXF) gives a take-off per service, each on its own layer; a PDF drawing gives whole-drawing totals, measured from the drawing's real geometry at the scale you set. Multi-sheet sets are measured sheet by sheet, and anything that can't be measured is named rather than dropped. • Memory, a searchable history, and your own tools connected — you approve every use. hYYa CLOUD — THE ONLINE ENGINE Switch engines when you want the frontier. Requires a paid hYYa Cloud account — pay per use with On-Demand credits, or subscribe monthly to Cloud Ultra. • The world's best AI models, from several leading labs — never tied to just one • Web search built in, with sources you can open and check • Connections — bring Gmail, Calendar, Outlook, Notion and Asana into the conversation • Agents — a daily brief from your connected apps, put together for you • Read your whole document set at once, and share a set with your team • Word, Excel and PowerPoint exports with your own branding • Bring your own AI provider key (Cloud Ultra) PRIVATE BY DEFAULT No tracking. No analytics. In Vault mode nothing you type, store or open leaves your device. The online extras — web search, connections, your own API keys — each stay off until you turn them on, and each tells you what it sends before it sends anything. Requires iPhone or iPad with iOS 26 or later. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://hyya.ai/privacy
