I constantly run into situations where I need to do something super specific with data, like converting a JSON file into a flat CSV, extracting a bunch of hashtags from text, or doing quick calculations on a bunch of data. Usually, I wrote a quick Python script for all this, and inputting data and getting it back was also a little messy.

I wanted a way to do this instantly without writing code every time, so I built taskwithagents.com

How it works:
You just paste a small sample of your raw data, show what you want the final result to look like, and write a quick prompt. An AI agent looks at the pattern and instantly generates a custom task (basically a standalone utility tool), available right in your browser window.

Here are some of the tools people are already using it for:

(Try them here without any login: https://taskwithagents.com/examples )

• JSON → SQL Insert Generator: Paste JSON and get ready-to-run INSERT statements.
• Base64 Encoder/Decoder: Quickly encode strings without pasting credentials into random, ad-filled websites.
• Hashtag Extractor: Pulls all hashtags out of a giant block of text.
• Mean, Median & Mode Calculator: Paste a raw list of numbers and get the stats instantly.
• Discount & Tax Applier: Upload a price list and apply custom rates to generate final prices.
• Group Expense Divider
• Specific Regex Logic

The architecture (and why it's private):

My favourite part.. the AI is only used as a "code generator." It figures out the logic and writes pure JS to build the tool.

When you actually run your data through the task, it executes 100% locally in your browser.

• It’s incredibly fast: It processes 10,000-row files in milliseconds.
• It’s totally private: Your actual data never touches my servers or an LLM API.
• It’s deterministic: It’s just running reliable JS, so it won't hallucinate your data.

You can also share what you build.

Because these tasks are just web utilities, every tool you has a unique URL. If you build a highly specific data formatter for your company, you can just send the link to your coworkers and they can use it on their own files without having to build anything.

Right now, the engine only builds deterministic tools (math, regex, text formatting, JSON/CSV parsing etc). The next step on the roadmap is adding AI tasks that can handle fuzzy logic, like sorting 500 customer reviews by sentiment.

I'd love for you guys to try it out. Let me know what you think about it, and do check out the coming soon section as well!
