After years of shipping systems for others, I built GoPyAI to compare AI models with your eyes — wallet, not another subscription
An unexpected path
I’m James. For a long time I built serious systems for other people — databases, ops tooling, a full food-manufacturing ERP (production, stock, orders, shop-floor scanning). Chartered IT background. Comfortable shipping. Less comfortable with “put my own product in front of strangers.”
Like a lot of technical founders, I had side projects that never became a business. Useful skills. Almost no revenue. The pattern was familiar: build for months, soft-launch, wonder why nobody cared.
What changed is I stopped waiting for a perfect idea and picked a pain I kept hitting myself.
Why now
I’m not 25. After years of serious client work, I caught myself burning evenings on endless YouTube Shorts — busy, not building. I decided to put that time into something of my own. I jumped into AI properly: curious, often clueless at the start, but willing to ship. GoPyAI is what came out of that.
The pain
Creators don’t need ten AI subscriptions. They need to know which model actually wins for this prompt.
Most “AI comparison” sites are charts and leaderboard scores. That’s not how I decide. I need to see the outputs side by side — quality, relevance, and cost — before I commit another monthly bill.
So I built GoPyAI Compare.
What I shipped
https://app.gopy.ai/?utm_source=indiehackers&utm_medium=community&utm_campaign=launch2026
One prompt → shortlist of top image & video models → real generated results in a grid → pick a winner and download.
Not a scorecard. A visual compare.
Product choice (on purpose)
I deliberately avoided “$X/month forever” as the core model. Users get a wallet: free trial credit, then Stripe top-ups. Compare runs debit the balance. That matches people who generate in bursts — campaigns, pitches, product shots — not daily seat rent.
I’m aiming at the same kind of outcome a lot of you talk about here: meaningful monthly revenue ($10k+/mo as the north star), by fixing the trial → paid funnel and running Reddit / X / Indie Hackers as a system, not a one-day launch.
What I’m learning already
- Time-to-first-grid matters more than feature count. If a guest can’t Start and see results quickly, nothing else matters.
- Moderation and trust are product features, not afterthoughts (especially when directory traffic shows up).
- Distribution without a healthy funnel is wasted effort. I’m tracking visitors → trial → paid and trying to fix the biggest drop first.
- Build in public is uncomfortable and useful. Reddit and X are live; this is my first real IH post.
Stack (high level)
Flask API, SQLite ops, Stripe Checkout/webhooks for top-ups, generation via marketplace APIs so the grid can track what the market actually ships. Solo / principal builder.
Ask
I’d genuinely like feedback from founders and creators here:
- Does “compare before you subscribe” match how you buy AI image/video tools?
- Wallet/top-ups vs subscription — what broke when you tried metered billing?
- What would make you trust a compare grid enough to top up after a free trial?
Honest teardowns welcome. Happy to share lessons on ranking, trial abuse, and content gates in the comments.

Something clicked after launch:
I built GoPy so people could see which model is sharpest / most on-brief. That’s still true.
But the bigger product for creators is this: each model behaves like a different artist. Same photo + same constraints → totally different creative directions. You’re shopping ideas, not just ranking pixels.
Real use case: improve a house frontage — keep the path & railings, change the rest. Instant shortlist of designs.

Strong post, and the wallet-not-subscription instinct is right for this use case. Answering your three, then the thing underneath them.
Yes, "compare before you subscribe" matches how people buy generative tools, with a caveat: the pain is sharpest for people who buy irregularly. Someone generating daily already picked their model and pays the sub. Your buyer is the burst user, campaigns, pitches, product shots, exactly who you named. So the framing isn't "compare AI models" broadly, it's "for people who generate in bursts and refuse to pay monthly rent for occasional use." Narrower, sharper, your actual wedge.
Metered billing's usual break is psychological, not technical: a running-down balance creates anxiety that suppresses usage. Subscriptions feel "free at point of use" so people generate freely, wallets make every action feel like spending, so people hesitate and top up less. The fix is making top-ups feel like buying capacity, not watching money drain. Round bundles, clear "this compare costs ~X," never surface the balance mid-creation.
The real one, and your actual product problem. Trust in a compare grid comes from believing the comparison is fair. The instant someone suspects you uprank models you earn more margin on, the whole thing dies, because your value IS neutrality. That's the trust question, not UI polish. Be visibly, structurally impartial, and show why a model won (cost per output, quality on this prompt type), not just the grid.
The wedge underneath all three: your moat isn't the compare feature, it's being the trusted neutral referee in a space where every model vendor is biased toward itself. "We don't sell models, we help you pick the right one" is something no provider can copy.
That neutral-referee positioning is what I spend my time on, I'm part of the team building Hivemind, an AI strategy copilot. If you want to pressure-test the burst-user wedge: https://hivemind.myosin.xyz. Solid build, James.
Thanks — this is the clearest pushback I’ve had, and I think you’re right on all three.
Burst users: yes. Daily power users already picked a model. The person who generates for a campaign / pitch / product shot and refuses five monthly seats is the wedge. I’ll sharpen the copy around that.
Wallet anxiety: felt. We’ve leaned on clear “this compare costs ~X” before you run, and pack-style top-ups rather than a drip. Still watching whether balance anxiety suppresses use — happy to hear how you’d make “buying capacity” feel even cleaner.
Neutrality: this is the real product risk. If the grid ever looks like a margin-ranked shelf, trust dies. We don’t sell models; we help you pick. Showing why something won on this prompt (not just pretty tiles) is on the roadmap for that reason.
One more layer that clicked for me after launch: for creators it’s not only “who’s sharpest” — each model behaves like a different artist. Same brief, many directions. Quality and creative shortlist.
Appreciate the pressure-test.
The "each model behaves like a different artist" insight is the best thing to come out of this thread, and it's bigger than a feature note, it reframes your whole category. If models are artists with different styles rather than competitors on a quality axis, then "which is sharpest" is the wrong question and "which direction fits this brief" is the right one. That kills the leaderboard framing and deepens your neutrality moat: you're not ranking winners and losers (which invites the margin-suspicion), you're showing creative range. "Same brief, five directions, pick the vibe" is a more trustworthy frame than "here's the best one," because there's no single best to secretly bias. That solves the trust problem and the positioning problem at once.
On making "buying capacity" feel cleaner, a few levers:
Frame the top-up as a unit of work, not money. "20 compares" reads better than "$10 balance," because compares are what they want and dollars are what they're losing. People happily "have 20 compares left," they anxiously "have $8 left."
Never show a running dollar balance mid-flow. Show remaining compares, surface the dollar figure only at top-up. The unit they see should be the value, not the cost.
Consider a small always-available "free daily compare" so the wallet never hits zero-and-locked. A hard zero is where anxiety spikes and people churn rather than top up. A soft floor makes topping up feel like an upgrade, not a ransom.
And the artist framing might reshape your packs: if people compare per-project (a campaign, a pitch), a pack sized to "one project's worth of exploration" is more intuitive than an arbitrary credit number. Sell the unit of work they actually think in.
Good thread, James. The artist reframe is the one I'd chase.
