Help

Usually the file loads images, fonts or scripts from the internet and Annopane blocks network access by default. Tap ⋯ top right → Settings → “Allow network”. If the file needs several files (CSS, images in subfolders), upload it as a ZIP – Annopane detects the start file automatically.

HTML (also as ZIP with subfolders, MHTML, web archives), Claude artifacts and exports from ChatGPT or Lovable, PDF, Excel/CSV, Word, PowerPoint, Markdown, images (incl. HEIC), code and Jupyter notebooks, Mermaid diagrams, audio and video. Office files are shown in simplified form; code is displayed, not executed.

Guest links without an account: 10 MB. With an account: 100 MB per file. During the beta there are no other limits – neither on the number of files nor on folders or versions.

In Claude, tap “Download” (or “Copy as HTML”) on the artifact, then upload the file to Annopane – on iPhone also via Share → Annopane. Even faster with the Claude connector (Settings → Connector): Claude places the file directly in your library and fetches the comments later.

Rendering happens entirely on your device – on first open Annopane fetches the matching viewer module (PDF about 0.5 MB) once. After that it is cached, also offline.

Tap the share icon top right in the viewer. Annopane instantly creates a link (with account: valid 30 days, commenting allowed; without account: guest link 7 days) and copies it. Under “More options” you set password, expiry and role.

Guest links are valid for 7 days, other links as long as the creator set. Ask the sender for a new link – the file itself is not gone on their side. As creator you find links and expiry dates in the share dialog.

No. The link opens in the browser; a name is enough to comment. Anyone who wants the page as an app on the home screen: share icon in Safari → “Add to Home Screen”.

Share → More options → set password and create link. The password is stored as a hash; recipients enter it once per device. We cannot recover forgotten passwords – simply create a new link.

Share dialog → list of links → trash icon. The link stops working immediately. Expiry dates can't be changed afterwards either – delete the link and create a new one.

Turn on comment mode (speech-bubble icon) in the viewer, then tap an element – heading, number, button, PDF region, spreadsheet cell. The comment is pinned right there with a number.

Comment list → “Export for Claude” copies all open comments as a ready-made instruction with the exact location (CSS selector, page, cell). Paste it, Claude applies the changes, upload the new version – the link stays the same and resolved comments are ticked off.

A connection through which Claude itself can publish files to Annopane and fetch comments. Settings → Connector → create token, enter the address shown in Claude under “Connectors”. The token can be revoked at any time.

Settings → Accounts → “Switch”. Files on the device are visible in both accounts, cloud files only in the respective account.

iPhone: in Safari tap Share → “Add to Home Screen”. Android/Chrome: menu → “Install app”. Annopane then starts full-screen, also offline for files on the device.

Files in device mode stay on the device you uploaded them on. For sync: open file → ⋯ → Settings → storage “Cloud”. This requires an account.

Settings → Account → “Delete account”, type the confirmation word. All cloud files, links and comments are deleted immediately and permanently; files on the device are kept. Super admins of a workspace hand over the role first.

Yes, for everything on your device: open, read, comment. Sharing, cloud sync and fetching other people's links need a connection.
