ENGINEERED FOR SPEED

Everything Notion struggles with,running natively on your local machine

Native Low-Latency Engine

Built with a lightweight desktop architecture. No heavy browser overhead, no multi-second loading spinners, and zero sync lag while typing. It opens instantly and stays responsive under heavy docs.

Anti-PDF Web Publishing

Turn proposals into clean, interactive web links on tarfio.com/p/... or your custom domain. Fix typos on the fly after sending without emailing updated attachments.

Developer Formats: MD, HTML, PDF

Zero proprietary lock-in. Your docs are clean files on your SSD. Import and export cleanly to raw Markdown (.md), standalone HTML bundles, or print-ready PDFs.

Live Read Telemetry

Know when clients actually read your proposal. Track scroll depth, time spent per section, and see if they engaged with your budget or skipped straight to the end.

Excalidraw + TipTap Canvas

Stop context-switching between tools. Embed interactive architecture diagrams, flowcharts, and whiteboards directly into your rich-text technical documentation.

BUILT FOR BUILDERS

Built for developers, technical founders, and agencies who close deals.

DevelopersClean local workflowsKeep your notes, specs, and proposals on your machine. Fast search, instant file access, and no forced cloud dependency while you draft.See how

Technical foundersCinematic web proposalsStop sending 10-page static attachments that get opened on a phone and instantly ignored. Tarfio generates sleek, responsive web documents: smooth transitions, reactive pricing calculators, high-res zoomable Excalidraw whiteboards, and pristine typography. Your proposal should look as cutting-edge as the product you build.See how

AgenciesActionable telemetryStop guessing if a deal went cold. Get alerted the moment they revisit your proposal so you can follow up at the exact right time.See how

See what clients read
before they reply

A sent link is not a read proposal. See who opened it, how far they scrolled and whether they came back — in one clear view of the document you shared.
