Markdown
Full GFM support: headings, lists, tables, quotes, task lists, code-block syntax highlighting, Mermaid diagrams, LaTeX math.
Local-first, lightweight, opens in under a second. Markdown, HTML, JSON, YAML, TXT, CSV — files never leave your device. Open source, fully transparent.
From ChatGPT-shared READMEs to Claude-exported research reports to JSON output from Codex — share directly, no conversion needed. More formats on the way.
Full GFM support: headings, lists, tables, quotes, task lists, code-block syntax highlighting, Mermaid diagrams, LaTeX math.
AI-generated single-file HTML, reports, dashboards, infographics — rendered in a sandboxed WebView with CSS / SVG / Canvas / local JS support.
Tree view, collapse/expand, key search, one-click formatting — complex API responses at a glance.
Config files, CI/CD workflows, Kubernetes manifests — collapsible groups with type hints.
Pure long-form reading experience with auto section detection, adjustable font size, and fullscreen mode.
Lightweight table view with horizontal scroll, column sort, and first-row field detection.
All rendering, parsing and caching happens locally on the device. Offline by default. Zero uploads, zero accounts, zero tracking. We never see your document content, and we don't ask you to sign up.
Parsing runs inside the system WebView on your device — never touches any external server.
Dangerous network access is blocked by default. JS execution is opt-in per document — you control every HTML file.
The local database stores only filename, path, type, and last-opened time. Document text is never persisted.
No analytics SDKs, no ad networks, no mandatory accounts. Just open and read.
Built for long-form reading — no notifications, no interruptions, no injected ads. You stay in control.
Follows system, or lock independently. Tuned contrast and color temperature for long reads.
Stepless font scaling, adjustable line height and width — remembered per document.
Hide status and nav bars with one tap and enter true reading mode.
Long Markdown documents get an auto-extracted H1/H2 tree, slide in from the side.
Keyword highlight in the current doc, cross-section jumps in milliseconds.
100+ language grammars; horizontal scroll for long blocks; optional line numbers.
Flow / sequence / class diagrams render inline — no need to switch to a browser.
Inline and block-level math rendering — papers and notes read as-is.
We don't replace ChatGPT, Claude, or Codex — we handle the last mile: making sure the files they produce actually read well on a phone.
Not an editor. Not a knowledge base. Not a social network. Just open → render → read.
Have your AI produce a survey in Markdown and read it on the subway. Mermaid diagrams, code blocks, and link references all render correctly.
""No more bouncing between browsers just to read a report.""
Open dashboard.html and infographic.html directly in the app — CSS, SVG, and Canvas render locally, with full offline support.
""The sandboxed WebView lets me open HTML from anywhere.""
Use NovaView as the default opener for every AI-generated file. Structured JSON views, scrollable CSVs, full-text search across docs.
""Preview.app for the AI era, on your phone.""
