§ 01
Built for reading

A reader, notanother tool to manage.

The markdown is the product. Everything else stays out of the way. A few decisions, then the page.

  1. i  

    GitHub native

    pg. 01

    Sign in with GitHub. Connect any public or private repo you have access to.

  2. ii 

    Sync once, read offline

    pg. 02

    Every page caches locally and opens instantly without signal.

  3. iii

    Smart incremental sync

    pg. 03

    SHA-based diffing. Only files whose contents changed are re-downloaded.

  4. iv 

    Obsidian-friendly

    pg. 04

    Wikilinks, YAML frontmatter, and TLDR callouts rendered natively.

  5. v  

    Tune your reading

    pg. 05

    Theme, font, size, spacing, and width all live-update as you change them.

  6. vi 

    Full-text search

    pg. 06

    Every cached file in your vault, instantly searchable.

§ 02
Pairs with Obsidian Git

Built for the wayObsidian users already work.

A calm reading surface for the vault you have already built.

Already keeping your vault in GitHub via the Obsidian Git plugin? Vault Reader picks up that same repository and renders [[wikilinks]], YAML frontmatter, and > TLDR: callouts the way you would expect.

How it fits with Obsidian
  • 01
    Wikilinks resolve locally
    Tap to navigate. Unresolved links stay visible but disabled, never silently broken.
  • 02
    YAML frontmatter is hidden
    Tags surface as small chips above the title.
  • 03
    TLDR callouts as cards
    Plus full markdown: code, tables, task lists, blockquotes, images.
  • 04
    Pull-to-refresh sync
    SHA-based diffing only re-downloads files that actually changed.
  • 05
    Offline by default
    Every page caches on your iPhone, so reading works without a signal.
§ 03
Page-level AI chat showing a seeded conversation about the current note
On-device AI

A thinking partnerthat never phones home.

Apple Foundation Models run entirely on your iPhone. No API keys. No subscriptions on top. Nothing leaves your device.

  • Summarize a page, or ask it to explain a passage in simpler terms.
  • Vault-wide chat surfaces answers linked back to their source pages.
  • Private by construction. No prompts or answers ever reach a server.
§ 04
Privacy by construction

A very shortprivacy policy.

We collect nothing, because the app was built that way. The whole policy fits on one screen.

Read the full privacy policy
  1. i

    Your token stays on device.

    GitHub OAuth tokens live in the iOS Keychain. Not in our servers, because we do not have any.

  2. ii

    AI runs on-device.

    Apple Foundation Models. Nothing leaves your iPhone, ever.

  3. iii

    No analytics. No tracking.

    No third-party SDKs. The app is read-only and cannot write back to your repo.
