Questions

Everything you wanted to ask

Quick answers about the tools in this category — what they cost, what they need and how they work.

Still have a question? We usually reply within one working day.

What can these tools build for me
Queries, patterns, whole files and the boring scaffolding around them. The AI SQL Generator writes the statement, the AI Boilerplate Code Generator sets up the skeleton and the AI CRUD Generator covers create, read, update and delete in one pass.

Do I have to write a perfect prompt
No. Describe the result you want the way you would describe it to a colleague. Mention the language, the table names or the fields involved and that is usually enough. If the first answer misses, add one more line and run it again.

Is the AI Regex Generator good with tricky patterns
It handles the patterns people normally get stuck on, such as emails, dates, log lines and validation rules. Describe what should match and what should not, and you get the expression back with a short reading of each part.

Will the tool explain the code it wrote
Most answers come with a short walkthrough under the code so you can see the reasoning before you paste anything into your project. Ask for more detail in the prompt and the explanation grows to match what you asked for.

Can I generate a full API layer
The AI API Generator drafts endpoints, request shapes and response bodies from a description of your resource. Pair it with the AI Function Generator or the AI Class Generator and you have a working starting point in a few minutes.

How do I get the file out of the browser
One click exports your result as TXT, DOC or HTML. Copy and paste works too. Since nothing is installed and no account is needed, you can open the tool on any machine, generate what you need and take the file away.

Does code generation cost anything
Not a cent. Every generator here is free with no cost and no trial, and there is no limit hiding behind a payment wall. Run the same tool as many times as a task needs while you tune the wording of your request.
