What's new

A dated log of what's actually been added or changed — kept honestly, so you can see at a glance whether it's worth a return visit. New content ships regularly.

Licensing, privacy and editorial transparency review

  • Added downloadable dependency notices and an installed-version inventory. Compiler, runtime and font license texts now accompany their distributions, with source-provenance limits stated explicitly.
  • Narrowed blanket originality, ownership and human-review claims to match the evidence. The editorial policy explains AI assistance and the difference between original teaching material, common programming patterns and third-party software.
  • Analytics preferences now handle blocked browser storage, synchronize changes between tabs and disable an already-loaded Google tag on withdrawal. Advertising stays inactive until a separate consent and disclosure implementation is ready.
  • Corrected unsupported NotebookLM and ChatGPT guarantees using official documentation, and aligned contact, accessibility and privacy disclosures with the implemented features.
  • This review does not certify universal originality or legal compliance. Exact corresponding-source coverage for prebuilt Java and R toolchains still needs independent verification.

Clearer learning paths, practical AI and safer developer tools

  • Existing lessons, concept guides, interview topics and visualizers now offer curated next steps into practice, projects and related teaching. JavaScript and TypeScript exercises link to the lessons they actually practise.
  • Selected tutorials now open with a direct answer, a small executable example and output. Language guides focus on learning, while their existing playground URLs remain dedicated compiler pages.
  • The AI hub connects existing developer guides in order and adds an original handbook question-answering project brief with retrieval and evaluation checks. Its model catalog keeps its separate October 1 source date.
  • The glossary now exposes the 19 original programming definitions and examples already in the content library, fixing coding pages' broken section links. The single sitemap.xml and existing page URLs remain in place.
  • AI lesson tables of contents now link to the actual rendered heading IDs. Editorial notes distinguish AI-assisted checks from independent human or expert review.
  • Homepage pathways include AI learners and interview preparation. Compiler assets warm on deliberate practice intent rather than downloading whole toolchains while you read. Regex checks run in a disposable worker with a timeout, and browser-storage and accessibility disclosures match the implemented behavior.

Modern AI learning hub and seven practical lessons

  • A new /learn-ai hub connects a learning roadmap, official model catalogs, SI / ASI explanations and practical lessons. Catalog facts are a dated snapshot, with links to the sources and no invented benchmark rankings.
  • Modern AI Literacy covers model selection, reasoning and multimodal AI, RAG, MCP, evaluation, privacy and licensing. The seven original exercises use self-written or fictional material.
  • New glossary definitions, visible content dates on learning cards, and improved discovery through navigation, site search, structured data and the sitemap. Dates reflect actual edits, not automatic freshness stamps.
  • Corrected the DALL-E tool entry and image comparison to identify retired API models, and removed unsupported assumptions about chatbot rankings and free-plan model generations.

Every language now has a full exercise path, a new cheat sheets hub, and a wider SEO and licensing pass

  • Bash, Go and C# now have full 10-exercise paths and practice hubs, joining the ten languages that already had one — every one of the 13 languages that run in your browser now takes you from a first program to a small complete one. Exercises include starter programs, reference solutions and output checks; runtime verification is separate from testing every exercise solution.
  • A new cheat sheets hub at /code/cheat-sheets collects every published syntax reference on one page, with the same honesty as everything else here: it says plainly which languages do not have one yet instead of hiding the gap.
  • The /licenses page now lists the main open-source components behind the six newest runtimes — Ruby, PHP, R, Bash, Go and C# — including an explicit note that the R runtime's binary distribution is GPLv3.
  • A pass through page titles and descriptions across the coding section, including the homepage's own, to keep them within what search engines actually show rather than truncating mid-sentence.

New playgrounds, references and career prep

  • C and SQL now run in your browser. C is compiled by the same real clang toolchain as C++; SQL runs on real SQLite with a fresh, empty database for every run. Both passed the sandbox's checks before being listed.
  • An HTML, CSS and JavaScript playground with a live preview, rendered by your own browser in a locked-down frame that cannot reach the network or this site's storage.
  • Interview prep with 100 original questions across nine topics and a mock interview mode you mark yourself, plus 58 concept guides covering fundamentals, data structures, web and APIs, databases, DevOps, security, AI for developers and SAP.
  • Six step-by-step DSA visualizers, ten in-browser developer tools, and searchable Git and Linux command references with warnings wherever a command can lose work.
  • JavaScript and TypeScript lessons and cheat sheets, ten more graded practice problems, and new guides to Dart, R and Bash.
  • A coding-first homepage and a grouped navigation menu, so it is easier to see where everything on the site is.

New section: Learn to Code

  • A coding section at /code where real Python, JavaScript, TypeScript, Java and C++ run inside your browser — real runtimes in a sandbox, nothing sent to a server, no account.
  • Free exercise paths of ten steps each in Python, JavaScript and TypeScript: every exercise hands you a working program, asks you to change one thing, checks your output and explains what went wrong in plain language.
  • Nine in-depth Python lessons with examples that were executed before publishing, a Python cheat sheet, and six practice problems graded against hidden test cases.
  • Playgrounds for all five languages, and written guides to fifteen languages — including C, C#, Go, Rust, PHP, Ruby, Kotlin, Swift, SQL and HTML/CSS — each with a first program, how to run it locally, a learning order and honest trade-offs. Guides say plainly which languages do not run here yet.
  • A single progress page covering coding exercises, practice problems, your daily streak and the AI course lessons, with export, import and reset. Nineteen programming terms joined the glossary.
  • New pages explaining how the code sandbox works (/security) and the open-source software it is built on (/licenses); the privacy, terms, cookie and copyright pages now cover the coding section. The Code link joined the main navigation and the glossary moved to the footer.

Tool comparisons and a hub for students

  • Five head-to-head comparisons: Cursor vs GitHub Copilot, Perplexity vs ChatGPT, NotebookLM vs ChatGPT, Zapier vs n8n, and Midjourney vs DALL-E. Each covers where both tools fall short and ends without declaring a winner, because two serious tools usually differ by suiting different work.
  • A comparisons index at /compare explaining how they are written: nobody pays to appear, no link earns a commission, and no benchmarks are published because a number we could not defend would be worse than none.
  • A new AI for Students hub gathering the courses, guides, prompts, tools and terms that suit studying — built around one idea: AI helps when it creates difficulty and hurts when it removes it.

Audit follow-through: dates, links, and a Prompt Engineering hub

  • A new Prompt Engineering hub collecting the course, the guides, the prompt library by category, and the key terms.
  • Every course lesson now links onward to the glossary entries, articles, prompts, and tools that go deeper.
  • Tool pages show the date their facts were last checked against the official site, and articles show when they were last updated. The sitemap now carries a real last-modified date for every page, taken from the site's edit history.
  • Course pages open with a clear Start the first lesson button, show reading time computed from the lessons' actual length, and link to what comes next.
  • Glossary terms link to the lesson or article that explains them; tools link to the prompts and lessons that suit them, and prompts list the tools they work well in.
  • Course lessons appear in site search. Listing pages are fully static again, with filters that work in the browser.
  • Accessibility: search boxes keep their focus ring, control borders and the progress-complete colour now clear WCAG contrast, copy-to-clipboard is announced to screen readers, and tap targets are at least 44px.
  • Removed a claim that the site offers hands-on projects (it does not yet), and an unsourced accuracy figure in one lesson.

New section: Agentic AI

  • New course: Agentic AI — six lessons on what an agent is, how tools and function calling work, the plan-act-check loop, where agents fail, and the guardrails worth having.
  • Three new guides: what agentic AI is, agents compared with chatbots, and how to decide what to delegate to an agent.
  • Seven new glossary terms covering agentic AI, tool use, function calling, the agent loop, multi-agent systems, human-in-the-loop review, and the Model Context Protocol.
  • Three new prompts for working with agents: plan before acting, delegate safely, and review an agent run against its log.
  • Two new tool listings: n8n and Claude Code, both covering agent-style features.
  • A new Agentic AI hub page collecting all of it, linked from the main navigation. To make room for it, the Pricing link moved out of the top navigation — the page itself is unchanged and is still linked from the footer.

Content expansion and a depth pass across every page

  • New course: Using AI in Everyday Work — six lessons on emails, summaries, research, meetings, and what never to paste into an AI tool.
  • Six new tools in the directory: Cursor, NotebookLM, Suno, Canva Magic Studio, Otter.ai, and Zapier.
  • Eight new prompt templates, including interview practice, code review, and flashcards from notes.
  • Twelve new glossary terms — GPU, API, chain-of-thought, deepfake, guardrails, and more (35 total).
  • Three in-depth guides: free AI tools for students, AI tools for developers, and using AI for your job search.
  • New Start Here page with a recommended learning path, plus this page.
  • Contact email moved to contact@skillaivibe.com.
  • Every AI tool listing now includes what the free tier actually covers, an honest section on where the tool falls short, who should skip it, and three concrete first steps.
  • Every prompt template now explains why its wording works, what good output looks like, the mistakes that produce poor results, and variations worth trying.
  • Course pages now state who the course is for, what you will learn, what you need beforehand, and where to go next.
  • Twelve articles were substantially expanded with worked examples, failure modes, and practical detail.
  • The pricing page was rewritten as a plain answer to whether the site is free, including how it is funded and what would change if advertising is ever added.
  • The About page now sets out what the site will not do — no invented statistics, no paid placement, no claimed credentials.
  • Legal pages moved from a red draft warning to a neutral note, with a visible last-updated date.

  • New Editorial Policy explaining how content is written, reviewed, and corrected.
  • New Accessibility Statement and Copyright Policy.
  • Site-wide search across courses, tools, prompts, glossary, and articles.
