What you can do here
Explore game ideas and game jam prompts, format and validate JSON, encode or decode Base64 text, count words, and clean up pasted lists. Collections bring related tasks together so you can find the right tool without opening an account.
Simple tools with visible limits
The current tools run in your browser. The generators combine curated themes and constraints; they do not call an AI model or create a playable game. Each tool page explains its inputs, outputs, examples, and limitations.
A JSON syntax check is not schema validation. Reading time is an estimate. Base64 is not encryption. We explain these differences so you can decide whether a tool fits your task.
Your work stays yours
You do not need to register to use the current tools. Tool input is not uploaded to a processing service by this website. Copy a result when you want to keep it; the website does not provide cloud storage or an account history.
About this website
ToolVelio is operated by ToolVelio (toolvelio.com).
The collection currently focuses on game brainstorming, developer text data, and writing utilities. We describe available features on each page rather than promising tools that have not been released.
