About
Game asset tools, file tools and AI commentary
Nerulio is a set of browser tools: a 2D game asset studio and Lab tools for sprites, pixel art and tilesets, plus image, PDF and media file tools. It also covers AI commentary for creators, and keeps source-backed reference pages and community channels as supporting material. Start with a task on the home page or browse the full tool directory.
How to read the information
Reference pages distinguish official sources, automated observations, community reports and estimates. Check the source, date, version and scope before using a value. An estimate or an individual report is not a measured result or a guarantee that a combination will work.
A browser studio for 2D game assets
Nerulio helps you prepare sprites, animations, texture atlases and autotile tilesets for a game. Open assets in the browser, inspect the result and export files for your engine.
Choose a workflow
Start with Sprite to split sheets and arrange animation frames, Pack to build an atlas, or Tile to inspect terrain rules. Pixel, texture and UI tools cover other asset tasks. Image, PDF and media editors remain available as supporting tools.
Projects and backups
Studio projects autosave in this browser and can be saved as .nerulio files. Local autosave is not cloud backup: clearing site data or changing device can remove access to it. Keep an exported project and original assets.
Compatibility and project support
Each tool page describes its output formats and limitations. Browser codecs, memory and the target engine affect results, so check exported files in your project. Explore the public source repository, issue tracker and component licenses below.
Corrections and maintenance
Use the information proposal form on a reference page for a correction with a source. Report inappropriate community posts through their report menu; the community rules describe moderation and the transparency page records aggregate handling. Reproducible tool problems and suggestions can be reported through the public GitHub Issues link on the Contact page. Never include private documents or passwords.
