Coming in 2.0

One Home. A new Watch workspace. The same privacy line.

The current candidate aligns iPhone, iPad, and Mac around Library, Notebook, and Watch. Every capability below is preview language, with compatibility and release gates kept visible.

Shared workspace

Start from Home, then choose the work.

The 2.0 candidate introduces a shared Home surface for Library, Notebook, and Watch, with Aurora, Paper, or Signal themes and separate Auto, Light, or Dark appearance.

Incoming TheOneConvert 2.0 Watch workspace on iPhone, starting with a blank address, Standard and Incognito modes, local Favorites and History, and separate data-clearing controls

Neutral start and local saved sites

Standard remembers. Incognito ends cleanly.

The Watch candidate starts blank and keeps saved-site choices separate from WebKit website data. Its Incognito boundary is a real non-persistent session, with one explicit exception for a Favorite you choose to save.

  • Watch starts without a bundled or remembered website
  • Standard uses persistent WebKit data plus local Favorites and normalized History capped at 500 completed visits
  • Favorites and History support opening entries and category-scoped single, selected, and delete-all actions; Favorites can also be renamed
  • Clear Website Data is separate from both saved-site categories
  • Incognito uses a non-persistent WebKit store, adds no History, and destroys its session on exit
  • A Favorite explicitly saved in Incognito persists locally; the visit and Incognito website data do not

Watch Favorites and History are local to the device and are not part of optional article-library iCloud sync.

Conditional native playback

WebKit discovers. AVPlayer handles only an eligible direct stream.

Physical-device AirPlay, Picture in Picture, background, lock-screen, quality, ad-to-main, and teardown validation remains a 2.0 release gate.

The website remains responsible for browsing, accounts, cookies, playback discovery, and provider controls. Native playback is a temporary in-memory handoff, not a downloader or compatibility promise.

  • Website discovery, sessions, sign-in, and provider controls stay in WebKit
  • Only eligible direct HTTP(S) HLS or MP4 can move temporarily to AVPlayer
  • AirPlay, Picture in Picture, background and lock-screen playback, Automatic/1080p/720p limits, live resolution, and exact time jumps are native-only capabilities
  • Unsupported, DRM, cookie-bound, or hidden sources remain website-only
  • Skip Ads is optional, defaults off, and is limited to short finite segments with a safety cap
  • Every player and workspace exit explicitly tears down website and native playback
  • Video is not downloaded, proxied, converted, saved, imported, or added to the article library

Also in the candidate

Intelligence with an availability check.

On-device summaries

Apple Intelligence reader summaries are available only when the system Foundation Models capability is supported, enabled, and ready. A summary is saved only after an explicit user action.

Simpler URL entry

Article and Watch fields add https:// when a scheme is omitted, while still accepting only HTTP or HTTPS addresses with a host.

The shipped 1.0 story

Everything here is available today.

The 2.0 preview adds a new workspace story without replacing the core private reading experience that shipped in 1.0.

Native app

Private by design.

Article conversion and incoming Apple Intelligence processing stay on-device. Library data can use optional iCloud under your Apple ID; incoming Watch Favorites and History stay local.

  • No account required
  • No native analytics or ad SDK
  • No external conversion or AI service
  • Optional iCloud under your Apple ID
  • Incoming Watch Favorites and History stay local
Online demo

A separate web service.

The public converter sends the URL you submit to the site server for one-off processing. The site can use Vercel Analytics. That behavior does not describe the native app.

  • Server-side public URL processing
  • Vercel Analytics on the website
  • No saved conversion history for you
  • Separate from the native app
Read the full privacy policyOpen support
Try online

The converter demo remains online.

Paste a public HTTPS article URL to generate Markdown, HTML, PDF, or EPUB. The result is transient; the native app remains the place for on-device conversion, the offline library, and notebook.

Paste a public article URL

Use content you are authorized to retrieve and convert. Some paywalled or JavaScript-heavy pages may remain unavailable to the hosted demo.

Demo privacy

  • Vercel Analytics can measure website-level traffic.
  • The page does not keep a saved conversion history for you.
  • The native app has no analytics or tracking SDKs.
  • See the privacy policy for the full separation.

Convert a public article and download the result.

The demo is intentionally separate from the native release and does not provide its local library or notebook.
