I got tired of spending an hour writing proposals -so I built a tool that does it in 30 seconds
Been freelancing for a while and proposals are always the part that take up a bunch of time.
So I built QuickProposal. It's a lightweight tool you open in your browser, fill in the project details, paste your OpenAI key, and it generates a complete professional proposal in about 15 seconds.
Covers: executive summary, scope of work, deliverables, timeline, pricing, terms, next steps. Tailored to the specific client, not a generic template.
Costs about $0.002 per proposal to run (OpenAI's API, you supply your own key).
Try it free (3 proposals): https://silly-gnome-d50ecc.netlify.app/

Would love feedback -what would make this useful for your specific workflow?
This feels useful especially for people like me who send proposals often but want consistency without rewriting everything.
This is super useful — proposals are such a hidden time drain. One tip: let users save a base style so outputs feel more personal, not generic.
Nice. Help me understand how this is better than using Claud/GPT that already does this for me?
Sharing my API key is not something many woudl be comfortable with. Im certainly not.
(playing devil's advocate here) if you can convince someone why your solution is better than claud/gpt, then perhaps a safer prop than the openAI key is using notebook lm so it can build a profile without ppl sharing access to their entire openai life.
Yes I would say that you need to help people have trust in their keys
This is very nice. You need to tell people that their keys are safe though.
Nice build — you removed a painful bottleneck.
One conversion tweak that usually moves paid upgrades: add a side-by-side “raw brief → final proposal excerpt” right above the upgrade CTA, with 3 callouts (tone match, clear scope, confident next step). People buy faster when output quality is obvious in under 20 seconds.
Also agree with the trust point above: a custom domain + one short privacy line near the API-key field should reduce hesitation.
If useful, I can run a compact teardown of the trial page’s conversion flow (headline/proof/friction/CTA hierarchy) here: https://roastmysite.io/go.php?src=ih_quickproposal_conversion_20260330_0746_hv
You solved the right friction: the part of freelancing that feels mandatory but adds zero value to the final work. If the tool reduces the gap between "project details" and "ready to send" without losing the tailoring, that's an hour back for every proposal, which compounds fast.
Smart move selling this on Gumroad instead of going the SaaS route. For something this focused, one-time purchase makes way more sense than monthly billing that nobody wants for a proposal tool. One thought on the pitch - "30 seconds" and "15 seconds" compete with each other in the copy. Pick one number and commit. Also the Netlify URL for the free trial doesn't build confidence. Even a simple custom domain would make it feel more legit - people are pasting client details in there so trust matters. The "bring your own API key" model is clever for keeping your costs at zero but it's also friction. Have you tested how many people drop off at that step vs a version where you just bake the cost in?
