Penlify: see which sentences read as AI, then fix just those (launching Sept 1)

Penlify · 2026-08-28T08:33:35.277-07:00

Hey Product Hunt,I built Penlify because most AI detectors give you one flat percentage and leave you stuck there. You get flagged, but you don't know which part of your writing actually triggered it. Penlify scores each sentence separately, so you can see exactly which lines read as formulaic, then rewrite just those in one of six tones without leaving the workspace.Free tier is 5 rewrites and 3 detections a month, no card required. Launching on Product Hunt September 1st.Would genuinely love feedback before then, especially on whether the sentence-level view is actually more useful than a single score, or if I'm overcomplicating it. penlify.app if you want to poke around.

My Best Work Yet

FetchrLy is the best thing I've built yet solo-founded, AI-powered, solving real job search pain. It finds recruiter emails on its own, sends tailored cold emails straight from the job description, and tracks opens all without manual work. This one means the most to me.

SaaS + Chrome extension. Finds recruiter emails from any job post, sends tailored cold emails, tracks opens, and keeps your full mail search history in one dashboard.

I vibe coded a SaaS that turns messy feedback into product specs — here's what I built

I vibe-coded SpecWise AI from scratch a tool that turns messy client feedback into clean, structured product specs instantly.

Here's the full stack I vibed with:

React + TypeScript + Vite frontend Supabase auth, database, RLS policies Vercel serverless deployment GitHub Models gpt-4o AI engine Paddle payments and subscriptions

The hardest part wasn't the code it was figuring out what to build next without a clear plan. Ironically, that's exactly the problem SpecWise solves.

Soft-launching VeilScan: proof-based security reports

Hey everyone, I m soft-launching VeilScan today.

It s a proof-based external vulnerability scanner for startups, SaaS teams, fintech products, and lean technical teams.

The problem I m trying to solve is simple:

Most small teams ship fast, but they don t always know what their external attack surface looks like. Traditional scanners often return long noisy lists, but not enough clear proof, context, or business impact.

I built InteliAds because KDP Amazon Ads are too easy to waste money on.

Hey Product Hunt, I m building InteliAds, a tool for KDP authors and self-publishers who run Amazon Ads for their books. Here s the thing. Amazon Ads can work, but managing them every day is painful. You have keywords spending money. You have search terms getting clicks but no sales. You have ACOS going too high. You have good keywords that should be scaled, but they get forgotten. And then you still need to check CPC, CTR, ROAS, bids, spend, orders, and campaign performance. So the real problem is not only running ads. The real problem is knowing what to do next. Should this keyword get a lower bid? Should this search term be negated? Should this target be paused? Should this winner be scaled? That s why I built InteliAds. It helps monitor Amazon Ads 24/7 using simple IF/THEN rules, so authors can reduce wasted clicks, control bids, pause weak targets, find winning search terms, and protect their book margins. Right now, it is rule-based, not full AI yet. I wanted the first version to be simple, controlled, and safe, because authors should not feel like a black box is spending their money. I d really love feedback from KDP authors, self-publishers, Amazon Ads users, or anyone who has managed PPC campaigns for books. What would you need to see before trusting a tool like this with your campaigns?

Perfect Ear EQ

Hi Hunters!

I built Perfect Ear because I was tired of standard browser-based audio boosters that make video and music sound like a crunchy, distorted mess at higher volumes.

Most sound boosters just amplify the signal blindly, leading to digital clipping. Perfect Ear uses a zero-clipping limiter alongside a studio-inspired 7-band EQ to give you absolute control over your audio while keeping the signal pristine.

I built an AI that reads 80-page gov solicitations for SMBs (live today)

Hey PH I'm Med, founder of WinBidIQ we're live on Product Hunt today.

The problem: winning U.S. federal contracts is a huge opportunity for small businesses, but most give up before they start. Finding the right opportunity on SAM.gov is a full-time job, and the average solicitation is 80+ pages of bureaucracy.
