Articos (site) is an AI research tool built to help founders "launch with confidence, not gut instinct" rather than rely on gut instinct alone. It's freemium with a free 7-day trial (2 free researches), then $47/month (Starter) or $119/month (Pro); one-time research packs start at $29 for 2 researches. Below are the alternatives from the list that are actually cheaper on paper, ordered from lowest starting price up.
Comparison table
| Product | Free tier | Starts at | Best for |
|---|---|---|---|
| Unask | Yes | $12/run | One-off research runs without a subscription |
| Neutropic | Yes | $16.40/mo | Budget-conscious teams comfortable with local models |
| Inamo | Yes | $22.06/mo | Feature-level user insight with real participant recruiting |
Unask
Unask (site) runs AI depth interviews with 15 personas, delivering results in minutes instead of weeks. It uses a pay-per-run model rather than a subscription: a free tier to start, then $12 for one run, dropping to $9.80/run at 5 runs and $7.90/run at 15 runs. This suits founders who want research on demand without a monthly commitment. The honest limitation: costs scale with usage, so heavy, ongoing research needs could end up pricier than a flat subscription like Articos's.
Neutropic
Neutropic (site) turns raw data into insights, aimed at teams tired of manual user research. Its free plan includes local models and unlimited API key usage, and paid plans start at $16.40/month (Light, billed annually at $196.80/year) up to $79/month. It's a good fit for technically comfortable teams willing to manage local models or their own API keys to keep costs low. One limitation: the cheapest tier requires annual billing, so the effective monthly cost is higher if you pay monthly.
Inamo
Inamo (site) is built to help teams "build the right features with real user insight." It offers a freemium model with a 30-day free trial and no credit card required, with paid plans starting at €20/month (about $22.06 USD) for the Freelance tier. It suits solo founders or freelancers validating specific features before building them. The catch: pricing is in euros with a currency conversion, and the brief notes additional costs for participant recruiting, so the real monthly spend can run higher than the listed starting price.
How to choose
If you need a single research task done fast without committing to a subscription, Unask's pay-per-run pricing is the cheapest entry point. If you're comfortable running local models or managing API keys yourself and want the lowest recurring cost, Neutropic's $16.40/month plan (paid annually) undercuts Articos by a wide margin. If your priority is validating specific product features with real user recruitment rather than broad market research, Inamo is the closest fit, though watch for the extra recruiting costs it flags.
