Technical Details

The app is built with a hybrid AI and system-aware architecture, prioritizing performance, privacy, and user control—without locking users into a single provider or workflow.

AI Models & Inference Options

Gemini 3 Flash (Cloud – Default)

Uses Gemini 3 Flash via Google AI Studio.

Optimized for speed and large-context summarization, with generous free usage limits—ideal for Batch Summaries and subreddit-wide analysis.

Apple On-Device Model

Suitable for short, individual post summaries.

Due to limited context size, Batch Summaries automatically fall back to an MLX model when needed.

Apple Private Cloud Compute Model

Accessed indirectly through the Shortcuts app, as Apple has not yet exposed this model to third-party apps.

  • Shortcuts briefly opens for each request, then automatically returns to the app
  • Slightly disruptive, but currently the only way to use this high-quality, privacy-preserving model from Apple

MLX Local Models (Hugging Face Compatible)

Supports any MLX model available on Hugging Face.

  • Enter a model identifier to download and run it locally
  • Already-downloaded MLX models on your device can also be reused

Text-to-Speech (TTS)

iOS Built-In TTS (Free)

Offline, no-cost audio summaries using the system speech engine.

OpenAI TTS (Optional, Paid)

Users may provide their own API key to access higher-quality voices from OpenAI.

Reddit Integration & Authentication

OAuth with Reddit

Authenticates via OAuth using the free API tied to each user's Reddit account.

  • No shared credentials
  • No proxy accounts
  • Fully compliant with Reddit API policies

Reddit API Credentials Setup (Client ID + Secret)

To connect your Reddit account, you'll create a personal Reddit "app" (this is how Reddit issues your API credentials):

  1. Log in to Reddit on a web browser.
  2. Go to User Settings → Safety & Privacy → Authorized Applications, or open Reddit's app prefs page directly.
  3. Scroll to the bottom and click "create another app…"
  4. Fill in the form:
    • Name: anything (e.g., MySummarizer)
    • App type: Choose Installed app (recommended for iOS/native apps)
    • Description: optional
    • About URL: optional (you can leave it blank)
    • Redirect URI: enter exactly the redirect URI shown in the app (Settings → Reddit / API Setup)
  5. Complete the CAPTCHA (if shown) and click Create app.
  6. After it's created, you'll see your new app listed:
    • Client ID = the short string under the app name
    • Client Secret = the value labeled "secret"
  7. Copy Client ID and Client Secret into the app's Reddit credentials fields.

That's it—OAuth will handle the login/permission prompt after you enter these.

System & UX Capabilities

Light & Dark Mode Support

Fully supports system-wide light and dark modes for a native iOS experience.

App Cache Management

Users can manually clear the app's cache to reclaim storage, reset local models, or resolve performance issues—without reinstalling the app.
