I built Nano2Image, a free-to-try AI image generator + text-based photo editor, because I wanted a product people can use immediately—no account wall before they get value.
You can try it here: https://nano2image.com/
What it does:
- Text-to-Image: type a prompt → generate images
- Edit with text: upload a photo → transform it with a text instruction
- Use-case templates so users don’t start from scratch (virtual try-on, vintage portrait, 3D figurine, product cutout, Japandi interior, etc.)
Free trial rules (honest version):
- No sign-up required: 1 generation per browser
- Enforced via an anon_id cookie (~30 days)
- It’s a soft limit (clearing cookies can reset)
- Protected with Cloudflare Turnstile to reduce abuse
- Sign up to get +3 credits
Monetization:
Free trial → credits model
Upgrade via subscription (monthly credits) or credit packs (one-time)
Credit packs never expire
Tech stack:
- Next.js + TypeScript + Tailwind
- Postgres + Drizzle
- Google Auth
- Gemini-2.5-Flash for image generation/transformation
- GA4 for funnel analytics
- Object storage for generated images (e.g., R2-style)
Biggest lessons:
- Speed is a feature
- Abuse protection is mandatory for free trials
- The pipeline/reliability matters more than the UI
If you’re building something similar, I’d love to hear how you handle free trials and pricing.
- better examples and galleries
- improved latency consistency at peak times
- deeper GA4 funnel instrumentation (landing → generate → download → paywall → purchase)
