Stay ahead of AI trends with automated Reddit insights! 🚀 This tool scans AI-related Reddit communities in English & Chinese, using Reddit Official API, DeepSeek V4.1 by OpenRouter to analyze posts, summarize key discussions, and track trends. Daily rankings hot topics—catch emerging trends before they go mainstream! (Updated every 6 AM CDT)

What it solves

This project automates the process of monitoring and synthesizing the vast amount of information shared in AI-focused Reddit communities. It solves the problem of information overload by aggregating posts, extracting content from linked videos and websites, and using LLMs to generate daily, structured trend reports in both English and Chinese.

How it works

The system uses a modular architecture to fetch data from specified subreddits. It includes "enrichers" that process different types of content: it uses vision models to describe images, extracts transcripts from YouTube videos, and scrapes web pages via Firecrawl. All collected data is passed through LLMs (via Groq or OpenRouter) to summarize discussions and identify trends. The project uses MongoDB for caching to minimize API costs and stores historical reports in an organized directory structure.

Who it’s for

It is designed for researchers, developers, and AI enthusiasts who want to stay updated on the rapidly evolving AI landscape without manually browsing multiple subreddits daily.

Highlights

  • Multimodal Analysis: Automatically processes images, YouTube transcripts, and web articles to provide context beyond just text posts.
  • Bilingual Reporting: Generates comprehensive summaries in both English and Chinese.
  • Cost-Efficient Design: Implements database-backed caching to reduce redundant API calls to LLM providers.
  • Flexible Configuration: Supports multiple LLM providers (Groq, OpenRouter) and allows fine-tuning of data collection strategies, such as smart comment fetching.

    lignertys/reddit-research-skills

    A set of Claude‑compatible skills that let AI agents query the third‑party reddapi.dev service for Reddit‑wide semantic search, trend analysis, subreddit discovery, and B2B lead scoring. Install via `npx skills add …` and then ask the agent natural‑language questions like “What are people saying about AI agent limitations?” The skill returns relevant Reddit posts and optional AI‑generated summaries. Requires a reddapi.dev API key and a paid plan for the lead‑scoring feature.

    dw-dengwei/daily-arXiv-ai-enhanced

    A GitHub‑only tool that daily crawls selected arXiv categories, uses a Large Language Model (default DeepSeek) to generate Chinese summaries, and publishes the results as a static site on GitHub Pages. It requires only a fork, a few secrets/variables, and runs via GitHub Actions—no servers needed.

  • Project
    Tomsawyerhu/Chinese-WebNovel-Skill

    A modular, retrieval‑augmented prompt framework for AI‑assisted Chinese web‑novel writing. It splits the workflow into a short router (`SKILL.md`) and many self‑contained sub‑skills (concept planning, opening, plot logic, dialogue, consistency review, etc.). Each sub‑skill ships tutorials, runtime rules, good/bad examples, and may use local novel corpora via a provided search script. The system routes a user’s brief idea to the appropriate module, pulls relevant example excerpts, composes a concise prompt, generates text, and finally runs a consistency review. Designed for Chinese novel authors, prompt engineers, and researchers interested in modular LLM writing pipelines.

    Jesseovo/last30days-skill-cn

    last30days‑skill‑cn is a Python‑based command‑line tool that aggregates the most discussed topics from eight major Chinese internet platforms (and optionally Hacker News, GitHub, Reddit) over the past 30 days. Designed for AI agents with CLI access, it can be installed and run via a single prompt, producing concise, source‑linked results in Markdown, JSON or offline HTML.
