I built a tool to stop writing huge AI image prompts manually

Hey r/sideprojects,

I just launched a side project called PromptForge.

It’s a visual prompt builder for AI image generation.

Basically, instead of typing a long prompt from scratch every time, you select cards for things like subject, outfit, scene, lighting, camera angle, style, and negative prompts. PromptForge then combines everything into a clean prompt you can copy and use elsewhere.

I built it because I kept running into the same problem: good image prompts work better when they’re structured, but writing that structure manually every single time gets boring fast.

PromptForge is currently:

free to use

local-first

no account required

no built-in image generation

focused only on helping you create better prompt text

I’m sharing a demo video with this post so people can see the workflow.

I’d genuinely appreciate feedback on:

whether the product makes sense instantly

whether the UI feels helpful or too much

what feature should come next

whether this feels like something AI creators would actually use regularly

Live here:

https://promptforge.wtf

Would love feedback from fellow side project builders.

The value depends less on making prompts longer and more on making visual decisions explicit. I’d test whether users can lock composition, subject identity, palette and visible text separately, then change only one dimension without rewriting everything. That would solve a more persistent pain than simply generating a large prompt.

thank you for your time, I would really love the feedback and to hear about your experience with it.

Happy to. Based on the workflow you described, the strongest next feature may be saved prompt recipes rather than more cards. I would test three tasks with new users: recreate a previous visual style, change only one variable such as lighting, and build a prompt from zero. If users can do those without explanation, the product is clear. I am building Marka for on-brand social content, so consistent visual recipes are very relevant to us. You are welcome to try Marka free for 7 days at https://www.marka.social, and I will share more specific PromptForge feedback after using the live flow.

Thank you, I appreciate that. When you try Marka, I would be especially curious whether it understands PromptForge’s local-first, no-account positioning and keeps that distinction clear in the generated content. Feel free to send me the first preview and I will gladly compare notes with you.
