Show IH: I turned a paid feature into a free tool as a lead magnet
Hey IH!
I'm building ChampSignal, a tool that tracks what your competitors are doing. One of the paid features watches news about companies you care about. It runs every day and sends alerts when a competitor gets press coverage.
A few weeks ago I was stuck on how to get more people to try it... then I thought: what if I took one feature and just gave it away?
So I built the Company News Finder.
What it does
You paste any company URL (like stripe.com). It searches thousands of news sources and pulls up to 10 recent articles from the last 30 days.
Each result gives you the headline, source, date, and an AI summary. So you can skim the news about any company in seconds instead of digging through Google.
No signup. No credit card. No account. Paste a URL, hit search, done.
I ran it on about 30 companies while building it and it found news for almost all of them, even smaller startups that barely show up on Google News.
Why I made it free (the honest version)
Two reasons:
1. Lead magnet. My hope is that people who like this will want the full version. The free tool gives you a one-time look. The paid version runs every day, scores each article by how important it is, filters out noise, and sends you alerts.
2. SEO. "Google Alerts alternative" gets about 150 searches/month. Not huge, but a free tool page could rank for it over time. For a solo founder, every visitor counts.
I know some people dress up their free tools like they're doing charity work. We're all founders here so I'll be real: this is a growth play. If it also helps people, even better.
The tech
For anyone who likes looking under the hood:
- SvelteKit for the frontend and server
- Exa AI for news search. It does a deep crawl across thousands of sources and catches stuff Google Alerts misses (niche blogs, smaller news sites). I tested it against Google News and Exa found way more results for smaller companies.
- Cloudflare Turnstile for bot protection without annoying CAPTCHAs
- One server action. Form submit hits the server, server calls Exa, results come back. No queues, no background jobs.
The paid version uses the same Exa engine but adds a GPT layer on top. Each article gets scored by how important it is and checked to see if it actually talks about the company. Then it filters out copies so 5 versions of the same press release become 1 signal. Only the stuff that matters sends you an alert.
What I learned
- Keep it stupid simple. I almost added date filters, source filters, sorting. Killed all of it. One input, one button. That's what makes people actually use it.
- Free tools cost more work than you'd think for something you charge $0 for. But zero friction means people actually try it.
- The words around the tool matter more than the tool. "Company News Finder" is fine. "Free Google Alerts alternative" gets way more interest. Same tool, different words.
What's next
I want to build 3-4 more free tools like this. Each one gives away a small piece of ChampSignal's tracking stack (website changes, SEO ranks, ad watching) as a tool on its own. A set of useful free tools that all point back to the full product.
Would love to hear from founders who've tried the "free tool as lead magnet" approach. Did it actually move the needle for you?
Happy to answer questions about the tech or the thinking behind it.
Smart move if the free tool solves one sharp problem and the paid product picks up right where it leaves off. Biggest gotcha from doing this is support load and accidental cannibalization, so it helps to set hard limits early and track whether signups actually convert, not just spike.
Total power move. I’m taking a similar approach with my SaaS, RankyPulse. I’ve made my reports for 30 major domains (Shopify, GitHub, etc.) public and indexable to drive SEO traffic, but I'm gating the 'Branded PDF' export as the revenue generator. It's a fine line between giving away value and keeping the 'Pro' incentive. How has your conversion been since making the switch?
The free tool as lead magnet move is underrated — it solves the trust problem upfront. Users get real value, you get qualified leads who already understand what you build. The key insight: the free tool has to genuinely solve a real problem, not feel like a crippled demo.
One thing that pairs well with this: using AI to help users get the most out of the free tool immediately. But the quality of AI assistance depends on how structured the prompt behind it is. I built flompt for exactly this — a visual prompt builder that breaks down AI inputs into semantic blocks (role, audience, objective, constraints, output format) so every user gets consistent, high-quality AI output, not a lottery. Free tools with great AI assistance = way lower churn on the upsell.
A ⭐ on github.com/Nyrok/flompt would mean a lot — solo open-source founder here 🙏
Love this approach and the honesty about it being a growth play. The one-input, one-button UX point is spot on — we saw the same effect when stripping options down to a single action. Curious which channel converts best for you so far: organic search, direct shares, or people coming from founder communities?
Great project! I'm also launching LinksWatcher today to help affiliates track 'Zombie Pages' via AI. It's a tough day at #139 but we're hanging in there! Good luck with your growth.
The honesty is refreshing, most people pretend it's purely altruistic.
Your point about words mattering more than the tool is the real insight here. "Company News Finder" is a feature name. "Free Google Alerts alternative" is a search query with intent behind it. Huge difference.
I've been thinking about doing something similar with Cleed — giving away a free "buying signal checker" for a single domain as the top of funnel. The free tool gives you a one-time snapshot, the paid version monitors it continuously. Your post just pushed me closer to actually building it.
How long before the SEO started showing any movement?
This mirrors exactly what I'm doing with QuoteSmith — built 7 free tools (quote calculator, invoice generator, profit margin calculator, etc.) for UK tradespeople, all pointing back to the paid AI proposal generator.
Your point about "the words around the tool matter more than the tool" really resonates. I renamed our "pricing estimator" to "free quote calculator for tradespeople" and the click-through rate from search doubled overnight. People search for solutions to problems, not product categories.
One thing I'd add: the free tools also give you incredible insight into what your target market actually cares about. Our day rate calculator gets 3x the traffic of any other tool — which told us that pricing confidence is the #1 pain point, not document formatting like we assumed. That shaped how we position the paid product.
The "3-4 more free tools" plan is smart. We found that each new tool compounds the SEO effect because they cross-link and build topical authority. Google seems to reward sites that go deep on a niche rather than wide across many topics.
The honesty about this being a growth play is refreshing. I'm doing something very similar in the accounting/bookkeeping space — built a free browser-based tool that categorizes bank transaction CSVs, and it's been my best acquisition channel by far.
Two things I've learned from the free-tool approach:
The "one input, one button" instinct is spot on. I had filters and options in my first version and usage doubled when I stripped them out. People want the result, not the configuration.
The SEO play takes longer than you think but compounds nicely. My tool pages started ranking after about 3 months, but now they bring in steady traffic without any effort. The key was targeting very specific long-tail queries rather than competing on broad terms.
Curious how you're measuring the conversion from free tool → paid. Are you tracking it through UTM params or something more sophisticated?
If you try it, drop the company you searched for here. Always fun to see what people look up first and what comes back.
