Every AI app I have used assumes the same thing about me. I will discover what I need, I will install it, I will remember which mode I am in, and I will switch tools when the moment calls for it. That is a lot of assumptions for one human running a company.
The hidden tax is real. You scroll a marketplace. You compare. You install the wrong one. You install three by mistake. You forget which one solved last week's problem. You re-install. You uninstall. You switch back. Multiply by every domain you actually work in (pricing, growth, content, code, hiring, ops) and the discovery layer becomes the bottleneck. Not the model. Not the workflow. The discovery layer.
We decided to remove that layer.
Skill OS, the short version
Fino ships with 200+ skills already inside. They are not "available." They are loaded. The router decides which one applies to the message you just sent, runs it, and badges the reply with which skill shaped the answer. You see what fired. You can ask why. You can override.
The skills span every domain a solo founder actually touches in a week. Pricing analysis. Growth diagnostics. Editorial calendars. Document drafts. Code review patterns. Operator playbooks. Compliance checklists. Founder coaching prompts. They were not picked from a popularity chart. They were picked because each one closes a loop a real founder kept asking for.
The install button is a tax on attention
When the app store is the product, "install" is the friction. You pay a small psychic cost every time you stop, evaluate, decide. That cost compounds across a week. By Friday you have spent more time deciding which tool to use than using any of them.
We benchmarked this. Skipping the install step recovers roughly 15 to 30 minutes a day for someone running a one-person company. Not from speed of execution. From speed of intent.
Routing beats listing
A 200-skill catalog you have to scroll is worse than a 10-skill app. Routing is what makes a large catalog feel like a small one. When you ask Fino about your churn rate, it does not show you a list of "growth tools." It calls the growth skill, runs the analysis, and tells you what to do. When you paste a contract draft, it does not show you a list of "legal tools." It calls the contract review pattern.
The skill catalog is observable. You can open it. You can read each skill's description. You can see which ones are derivatives of open-source libraries (we name every upstream). But you do not need to open the catalog to use Fino. The router is the interface.
Trade-offs we accept
A pre-installed catalog has costs. We pay them so you do not have to.
First, we curate. Every skill that ships in the base catalog passes a license audit, a voice audit, an Apple 4.3(b) review for any advisor-shaped language, and a private-stack leak guard for content that should not appear on a public surface. The internal cost of curation is real. We trade it for your install time.
Second, we maintain. Skills go stale. Pricing changes. Pattern advice that was true in 2023 is wrong in 2026. Every skill in the catalog has a last_updated field and a refresh cadence. We will pull the ones that drift.
Third, we are honest about what each skill is for. A skill is not a magic wand. It is a structured prompt + a reasoning frame + a closed-set of outputs. Some skills cost more to run than others (latency, tokens, third-party API spend). We surface the cost class so you know what you are paying for.
The pitch in one line
The best app store is no app store. The best install button is no install button. Skill OS routes the right capability at the right moment, and the catalog grows in the background. You do not manage it. It manages itself.
Where this goes next
We are still adding skills. The current count is the floor, not the ceiling. New first-party skills ship monthly. Curated open-source skills (MIT, Apache-2.0) ship as we audit them. Community-contributed skills get a separate visible tier so derivatives stay attributed.
If you want to follow the catalog as it grows, the skills changelog has an RSS feed. If you want to see which skills are already inside, the catalog page lists every one with its source, license, and tier.
The install button was never the feature. The capability was.
