ZTool - Create data tools & scripts with just a few words

ZTool.co is the personal developer for entrepreneurs, analysts, and marketers


Describe the tool you need in one sentence and ZTool will create the code, run it, and present the output. We particularly focus on all things CSV files: anything from exporting csvs, to merging files and enriching data is possible. Over time, users can edit, build out and share their library of tools with each other.


Python scripts for tools like scrapers or workflow automations have been written thousands of times before. Reusing that code — and saving time — should be easy but it’s not: finding the relevant scripts is hard, and adapting it to your specific case requires a certain level of skill at which one can just write the code from scratch. ZTool solves both the search problem and the skill problem; it will give you the exact script you need, specific to your use case, and regardless of your technical ability.


All the user has to do is describe the script they want, for example: merge two CSV files. ZTool, powered by LLMs, will ask specifying questions, ask for the input files, and then create an output file. That’s it!

How we came up with this

While working as an analyst at a VC firm many years ago, Jonas hacked together a script to process csv data for a deal analysis. It was a simple script but it saved him days worth of manual work. Over time the initial script proved useful for more and more deals and grew into an entire library of Python scripts for automating different tasks, from data analysis to web scraping. It took Jonas a week to create that initial script and he had to learn Python, regex, SQL, Docker, cloud, and more—with ZTool anyone could have done it in 5 minutes.

Concrete ask

ZTool has a blessing and a curse, and they turn out to be the same thing: it is super powerful and can be used to generate all sorts of scripts. Help us figure out what we should focus on by trying it out and showing us what tools are most useful to you!
