Hey PH! I'm Shrikrishna — maker of PromptQuill. AMA 👋

Hey Product Hunt!

I'm Shrikrishna from Error404 Studio (as a Founder) and I built

PromptQuill over the last 4 months — mostly

nights and weekends.

The story behind it:

I kept getting disappointing outputs from

ChatGPT. Not because the AI was bad — but

because my prompts were vague. I'd spend

more time rewriting the prompt than actually

using the output.

So I built a tool that does it for you.

Describe your idea in plain language →

PromptQuill generates a perfectly structured

prompt → paste into any AI model → get

dramatically better output.

What makes it different:

→ 6 modes each with its own AI pipeline

(General, Startup Pro, Coding, Content,

Creative, Research)

→ 2 personalities: Bot (structured/technical)

or Human (conversational/natural)

→ Pay-as-you-go credits — no forced subscription

→ Community forums for prompt engineers

Free plan available — 10 generations/day.

No credit card needed.

I'd love to know:

1. Which mode would you use most?

2. What's your biggest frustration with AI outputs?

3. What feature should we build next?

Ask me anything — I'm here all day 🙏
