Product How Parsepad Builds a Working Tool From a Single Sentence Most tool sites give you a fixed catalog. Parsepad adds a second option: describe the tool you need, and the AI builds, tests, and repairs it until it works. Here's what happens between your sentence and a working tool. Read article 
Documents PDF, DOCX, and Markdown: How Document Conversion Actually Works Converting between PDF, DOCX, and Markdown isn't lossless magic — each format stores a document differently. Understanding those differences tells you what survives a conversion and what won't. Read article Three moves from problem to output

Ready when you are
Still missing the right tool?
Describe it in a sentence and ParsePad builds it — writing the tool, testing it in a sandbox, and fixing its own mistakes until it passes. Building a tool takes a free account.
Build a toolFrequently asked questions
Are ParsePad tools free to use?
Yes. Every tool on ParsePad is free with no account required. Open the URL and start working. Any paid, trial, or limited tool says so on its card before you open it.
Can ParsePad build a tool that doesn't exist yet?
Yes. Describe the tool you need in plain language and ParsePad's AI generates a working one — it writes the tool, tests it in a sandbox, and fixes its own mistakes until it passes. You can then use it, pin it, or share it.
Where does ParsePad run my data?
It depends on the tool, and each tool's card tells you before you open it. Formatters, converters, and validators run entirely in your browser — your data never leaves your machine. Tools that compile code, call live data, or are built by AI run on secure, isolated infrastructure.
What kinds of tools does ParsePad cover?
Tools across code and compilers, data, documents, finance, business, network, and SEO — from JSON formatting and conversion to invoice generation, QR codes, and live data dashboards. And if the tool you need isn't there yet, describe it and ParsePad's AI builds it. The directory at /tools has the full list with filters by category and task.
How do I find the right tool?
Search by task or format rather than tool name. Typing 'json' shows everything that works with JSON. Typing 'validate' shows validators across all formats. The category links on the home page group tools by data family if you would rather browse.
Can I request a tool that does not exist yet?
Yes. The /feedback page has a tool request form. Requests that include the payload shape, expected output, and a concrete failing example are easier to evaluate and tend to move faster.
