Why we started
Most software in any category follows the same playbook: add features until the product is unrecognizable, monetize through attention rather than value, and make the free tier just painful enough to force an upgrade. We found this pattern exhausting as users, and we decided to build differently.
Solune AI started with a single question: what would a tool look like if it was built purely around the task it was supposed to solve? No onboarding flows. No engagement metrics optimized against your attention. No upsell modals blocking the thing you came to do. Just the tool, working, the moment you open it.
Our first answer was Flesh — an AI image enhancement model focused specifically on recovering skin micro-texture that gets destroyed by JPEG compression and conventional upscaling. It does one thing. It does it well. That philosophy carried forward into everything we've built since.
How we approach AI image enhancement
Generic upscalers are trained to maximize perceptual sharpness across a broad range of content. The result looks crisp in a demo but falls apart on portraits — the fine detail that makes skin look real (pores, vellus hair, subtle surface variation) gets smoothed into plastic. Our models are trained differently.
We work from high-resolution reference datasets captured specifically to preserve high-frequency texture. Our loss functions reward texture fidelity, not just edge sharpness. Every model is evaluated against human expert judgment before it ships — not just against benchmark scores. The result is enhancement that holds up under close inspection, at print resolution.
We currently support output up to 4K resolution, with input formats including JPG, PNG, and WebP. Enhancement processing runs on cloud infrastructure and is designed to handle professional-grade files without the file size limitations that constrain most browser-based tools.
Engineering and productivity tools
Beyond image AI, we've built a growing library of engineering calculators and productivity utilities. These tools fill a specific gap: professional-grade reference tools that work instantly in a browser, with no installation, no account wall, and no requirement to navigate a desktop application with a 1990s UI to do a single calculation.
Our RF engineering tools cover VSWR, impedance matching, transmission line analysis, and frequency planning. Our mechanical and electrical engineering calculators handle stress, power, voltage, and fluid flow — with clearly labeled units and formula references that make them useful for both on-site checks and exam preparation.
We validate every calculation against reference standards before shipping. If a tool gets a number wrong, it's worse than useless. That bar — correctness before anything else — shapes how we test and release.
Our commitment to privacy
We don't store uploaded images beyond the processing window. We don't train our models on user-submitted content. Tools that don't require an account collect no personal information. For tools that do require authentication, we use Google OAuth and store only what's necessary to operate the service.
