The catalog ranges from beginner material such as AI Python for Beginners to advanced courses on transformers, LLM inference, and building agentic applications, with a strong emphasis on hands-on practice rather than theory alone. The platform is model-agnostic: courses teach concepts and workflows you can apply with whatever tool or framework you prefer, from classical machine learning to modern generative AI and agent frameworks. Short courses make it easy to learn a single topic in an afternoon, while full specializations and professional certificates support longer career development paths. Beyond video lessons, DeepLearning.AI publishes "The Batch," a widely read weekly newsletter written by technical experts, and maintains an active community forum. A Pro membership unlocks all course videos, coding labs, quizzes, and industry-recognized certificates, with a Team Plan available for organizations that want to train groups of employees. **Pricing & Plans:** Freemium. Many course videos can be watched for free, and The Batch newsletter is free to subscribe to. A paid Pro membership adds hands-on coding labs, practice quizzes, exclusive courses, and professional certificates, with a separate Team Plan for larger organizations. Check the official pricing page for current rates. - **130+ courses and specializations:** A broad catalog covering machine learning, deep learning, transformers, generative AI, prompting, and agentic AI, with tracks for data/ML practitioners, software developers, and complete beginners. - **Professional certificates:** Industry-recognized certificates and specializations designed to signal job-ready skills, supported by coding labs and portfolio projects you can show in interviews. - **The Batch newsletter:** A free weekly newsletter written by technical experts that summarizes the most important AI news, research, and analysis for developers and practitioners. - **Hands-on coding labs:** Pro members get interactive labs and practice quizzes so they can apply each concept immediately rather than only watching lectures. - **Learning paths and community:** Goal-based learning paths plus an active forum let learners plan a route from their current level to their target role and get help along the way. **Strengths:** Founded and taught with input from Andrew Ng, a widely trusted figure in AI education; Very broad catalog spanning beginner basics through advanced generative AI and agent systems; Free videos and a free newsletter make it easy to evaluate before paying; Hands-on labs, certificates, and portfolio projects add practical credibility **Limitations:** The most valuable features such as coding labs and certificates sit behind the Pro membership; Advanced specializations require a real time commitment to finish; Some brand-new topics are covered as short courses rather than full-depth curricula [Profile (Markdown)](https://openaitools.app/tool/deeplearning-ai.md) ## Zeli Zeli solves the oldest problem with Hacker News: the front page is a list of headlines, and deciding which of the thirty stories deserves your attention means opening all of them. Zeli mirrors that front page, attaches an AI-written summary and a representative key quote to each story, and translates everything into seven languages. The ranking tracks news.ycombinator.com and refreshes every fifteen minutes, so the feed stays current without you checking the orange site directly. The structure is built around permanent, citable pages. Every story gets a URL keyed to its Hacker News item id — zeli.app/story/{id} in English, or zeli.app/{lang}/story/{id} for the other languages — carrying the translated title, the original title, a summary, a key quote and translated highlights from the discussion. Every day also gets a permanent archive of the complete front page, so a digest can be retrieved after that day has scrolled away. Alongside the news feed, Zeli digests HuggingFace's daily AI papers with translated titles and summaries, which makes it useful for keeping up with research as well as with developer chatter. Content languages are English, Chinese, Japanese, Korean, German, Spanish and Russian, with English served at the root and no language prefix. There is no account, no API key and no cost; an RSS feed bundles one item per day instead of flooding your reader, and the site can be installed as a PWA. For programmatic use, Zeli also publishes plain-markdown daily digests, JSON endpoints and an RSS feed aimed at feeds and AI agents. It requires no JavaScript and is served from an edge cache, so it is unusually light to read. **Pricing & Plans:** Free. No account, no API key and no payment; the full site, the RSS feed and the machine-readable digests are all available at no cost. - **AI summaries on every Hacker News story:** Each story carries a short summary generated from the linked article plus a standout key quote, so you can judge relevance before clicking through. - **Seven-language translation:** The whole feed — titles, summaries and top comment highlights — is available in English, Chinese, Japanese, Korean, German, Spanish and Russian. - **Daily front-page archive:** Every day gets a permanent page containing every story that hit the front page, retrievable long after the feed has moved on. - **HuggingFace AI paper digests:** Daily AI papers are surfaced with translated titles and AI summaries, making Zeli a research reader as well as a news reader. - **Machine-readable outputs:** One-item-per-day RSS feeds, plain-markdown digests, JSON endpoints and a sitemap make Zeli easy to pipe into readers or AI agents. **Strengths:** Turns the Hacker News front page into a fast, scannable daily brief; Seven languages with genuinely translated titles, summaries and comment highlights; Permanent, citable story and daily archive pages that never expire; Free, no signup, no API key, installable as a PWA **Limitations:** Summaries are machine-generated and are not fact-checked by a human; Real summaries exist only in seven languages — other locales fall back to English; It covers Hacker News and HuggingFace papers only, not your own reading list or arbitrary URLs; Keys off Hacker News ranking, so niche topics that never hit the front page are not included [Profile (Markdown)](https://openaitools.app/tool/zeli.md) ## Frequently Asked Questions ### How do DeepLearning.AI and Zeli compare in monthly traffic?
