Zhihu-Hyperion

Project Overview

Zhihu-Hyperion is a third-party Zhihu client that keeps ads, promoted posts, product placement and paid Yanxuan columns out, with a Lite build under 5 MB that still delivers the full reading, interaction and creation experience.

Built on Kotlin Multiplatform and Compose, Android, iOS, Windows, Linux and macOS share one interface; one tap summarizes answers with AI, the Full build runs an on-device semantic model offline for meaning-based blocking, and a local recommendation algorithm puts feed weights in your hands.

Item	Value
Platform	Android, iOS, Windows, Linux, macOS
Stack	Kotlin Multiplatform + Compose Multiplatform
Size	Lite under 5 MB (official Android app exceeds 110 MB)
License	AGPL-3.0

A Zhihu client under 5 MB, ads and paywalls gone, your feed your rules.

Key Features

• Deep blocking: removes ads, promotions, product placement and Yanxuan paid content, with regex blocklists, user and topic mutes plus quality filters by likes
• Local feed: recommendations computed entirely on device with tunable weights, or switch to web, Android or hybrid modes
• AI summaries: one-tap answer and article summaries via Zhihu Direct Answer
• Semantic blocking: the Full build embeds ONNX Runtime for offline meaning-based blocking and named AIGC suspicion marks
• Multi-account: phone code, QR scan and cookie logins with free switching
• Complete browsing: answers, articles, pins, hot lists, dailies, search and favorites all covered
• Anti-bubble: toggle logged-in and logged-out feeds to escape filter bubbles
• No telemetry: the app reports nothing

Target Audience

• Users plagued by Zhihu ads and paid inserts
• Power users who want control of their feed
• Multi-device users reading on iPhone, iPad or desktop
• Users who care about install size and memory

Quick Start

1. Download your platform's package from Releases; most Android users want the Lite build
2. Sign in with a phone code or QR scan
3. The home feed arrives ad-free; tune recommendation modes and blocking rules in settings
4. While reading, tap AI Summary for quick key points
5. For semantic blocking, switch to the Full build, the model runs fully offline

Core Advantages

• Ultra lightweight: Lite under 5 MB with far lower install and runtime footprint than the official app
• Clean reading: ads, promotions, placement and paywalls all removed
• Two AI forms: cloud one-tap summaries or an on-device semantic model, as you prefer
• Five platforms, one codebase: consistent experience and synchronized updates

System Requirements

Item	Requirement
Android	Mainstream versions, Lite and Full builds
iOS	iOS 16+, self-signed install
Desktop	Windows MSI, Linux AppImage, macOS Apple Silicon

Notes

• iOS self-signing: the IPA is unsigned, sign it with AltStore, SideStore or your own developer certificate first
• Lite vs Full: the on-device semantic model and a few extras are Full-only, choose by need
• Third-party risk: relies on unofficial APIs, Zhihu changes may affect features
