#Tools By AI

#Tool Overview

#🌍 Translation Tools

Three format-specific translators (subtitle, Markdown, JSON i18n) sharing 8 translation APIs and 21 LLMs across 120+ languages.

• Subtitle Translator — SRT / ASS / VTT / LRC with timecode alignment and bilingual output
• MD Translator — Markdown that preserves code blocks, LaTeX, and Front Matter
• JSON Translate — i18n JSON with selective key translation and key mapping

→ Enter Translation Tools

#📝 Text Tools

Four complementary text utilities covering format conversion → content cleanup → chunking → general-purpose ops.

• Chinese Conversion — Simplified ↔ Traditional, regional variants
• Novel Processor — web-novel TXT formatting, ad removal, chapter fixes
• Text Splitter — split by chars / paragraphs / delimiter
• Text Toolbox — regex match, dedupe, batch prefix/suffix, line ops

→ Enter Text Tools

#🔧 JSON Tools

Seven complementary JSON tools covering read → edit → add → cross-dataset sync, all JSONPath-based.

• JSON Value Extractor — read: pull fields via JSONPath
• JSON Node Edit — edit: batch prefix/suffix, replace, overwrite
• JSON Node Inserter — add: insert fields after a target node
• JSON Match & Update — sync: merge values across datasets by ID

→ Enter JSON Tools (all 7)

#Three Steps to Start

1. No signup: every tool is free and runs purely client-side — just open and use
2. No API key needed (for translation): the default free GTX engine works out of the box; switch to DeepSeek / Claude / GPT in the top-right settings when you want higher quality
3. Data stays on your machine: API keys and translation cache live only in your browser's localStorage / IndexedDB

#Philosophy

The age of AI has arrived, and everyone can now customize their own exclusive tools.

I truly enjoy using AI to write tools or scripts, but to be honest, I still remain cautious about the current capabilities of AI. While it can certainly help us with basic, repetitive tasks, it often falls short of ideal outcomes.

Therefore, I prefer to use AI as an assistant in tool creation rather than handing over complete tasks to it. The popular concept of "AI agents" today essentially involves organizing multiple AI tools into a workflow—the core of which still relies on human-defined processes.

My preferred approach is to "toolify" specific tasks. By leveraging AI's abilities, I develop individual, controllable, and practical standalone tools to ensure that every step of the process meets expectations.

Tools By AI is built on this very concept. It uses AI-assisted programming to turn ideas into practical tools. This document, in turn, provides a detailed explanation of the methods and logic behind using these tools.
