GistReader

Accepts article URLs and generates AI-powered summaries by fetching content, extracting text, and processing through an undisclosed LLM backend with per-tier quota enforcement (100-unlimited summaries/month depending on subscription). The system manages concurrent summarization requests and enforces rate limits, returning cleaned text summaries alongside the original article content for user comparison.

Maintains a centralized backend state store that syncs user's saved articles, feeds, reading progress, and preferences across web browsers, mobile devices, and desktop clients. When a user saves an article on one device, the cleaned content and summary become immediately available on all other authenticated devices without manual re-fetching or re-processing.

Supports summarization in three languages (English, Dutch, Mandarin Chinese) with automatic language detection or user-specified language selection. The summarization pipeline processes content in the detected language and returns summaries in the same language, enabling non-English readers to consume content in their preferred language.

Supports importing feed subscriptions from OPML files (standard format for RSS feed lists) and exporting user's feed subscriptions back to OPML format. This enables users to migrate their feed list to/from other RSS readers without manual re-entry, reducing vendor lock-in.

Accepts OPML feed subscriptions and automatically fetches, parses, and cleans articles from RSS feeds by removing ads, tracking pixels, and non-content elements. Each feed item is processed through a content extraction pipeline that isolates article text, preserves formatting, and renders in a distraction-free format. Cleaned content is then available for summarization or full-text reading.

Accepts YouTube video URLs and converts video content into readable text format (mechanism unknown — likely transcript extraction or video analysis), then applies the same summarization and cleaning pipeline as article content. Users can read a summary or full transcript of a YouTube video without watching the entire video.

Converts article summaries into audio podcast format using text-to-speech or AI narration (provider unknown), generating playable audio files that users can listen to while commuting, exercising, or multitasking. Quota-limited per tier (5-30 podcasts/month), suggesting backend resource constraints or licensing costs for audio generation.

Integrates with Pocket (Mozilla's read-it-later service) to import saved articles and reading list metadata into GistReader. Users can authenticate with their Pocket account and bulk-import their existing saved articles, which are then processed through GistReader's cleaning and summarization pipeline.

Applies content extraction and DOM cleaning to render articles in a distraction-free format by removing ads, tracking pixels, sidebars, and non-essential UI elements. The cleaned content is displayed in a minimal, typography-focused interface with configurable dark mode, font sizes, and reading width to optimize readability.

Implements a freemium pricing model with four tiers (Free, Bronze, Silver, Gold) that enforce quotas on core features: feed count (100-unlimited), summaries per month (100-unlimited), and AI podcasts per month (5-30). Quota limits are enforced server-side, preventing users from exceeding their tier's allowance and triggering upgrade prompts when limits are approached.

Provides keyboard shortcuts for common actions (navigation, marking as read, saving, etc.) to enable power users to manage their reading list without mouse interaction. Shortcuts are documented and customizable (mechanism unknown), allowing users to optimize their workflow for speed.

Provides a dark mode UI theme that reduces eye strain during low-light reading and syncs the user's dark mode preference across all devices. When enabled on one device, dark mode is automatically applied on all other authenticated devices without manual re-configuration.
