Rune is a browser-based platform for builders that bundles 145+ free in-browser tools, programming tutorials, AI learning, and an AI career suite in one account.
What is Rune?
Rune is an all-in-one web platform that combines utility tools, technical education, and job-search software. You give it files, questions, or resume data; it returns processed files, step-by-step explanations, and ATS-scored documents. Everything runs in a standard web browser, and the tools process data locally on your device rather than on a server. The platform is built and maintained by a solo developer, with tutorials written by the Rune Hub Team.
Key Features
- 145+ browser tools — PDF Toolkit for merging, splitting, compressing, and converting PDFs; an Image Editing Suite with background removal, compression, resizing, and format conversion; Developer Utilities including JSON formatter, regex tester, base64 encoder/decoder, JWT debugger, and 30+ more; plus text, video conversion, and security scanner tools.
- Private local processing — Every tool runs directly in your browser tab. The site states that files are never uploaded to a server and there is no tracking, so you can handle sensitive documents without privacy trade-offs.
- Rune Hub tutorials — An ever-growing library of programming guides, including a JavaScript Fundamentals track with 18 beginner, intermediate, and advanced topics, plus dedicated tracks for Python, Data Structures & Algorithms, React, Next.js, and AI.
- Rune Learn AI study buddy — Generates personalized explanations, custom quizzes, adaptive learning roadmaps, and 24/7 AI chat support. It also includes flashcards with spaced repetition and a doubt solver that provides step-by-step reasoning.
- Rune Career suite — A resume builder powered by GPT-4.1, a real-time ATS checker that scores your resume and gives actionable tips, an AI cover letter generator that works from a job link, a one-click portfolio builder, and recruiter matching.
- Free tier with no email wall — You can start using the core tools immediately without creating an account. The site promises no email walls and no upsells in front of basic features; paid tiers (Plus, Pro, Ultimate) exist for higher limits and premium functionality.
Who is it for?
