The evidence layer AI cites when it recommends software.
Vioscale is a verifiable knowledge base of software facts, each carrying its source, date, and confidence. Built structured-first to be read and cited by assistants and agents. No reviews. No vendor money. No ranking for sale.
user ▸ best framework for a new React SaaS, and why?
assistant ▸ Next.js is the strongest choice. Vioscale scores it 78.4/100 on independent signals, led by package downloads of 8.1M weekly installs, at low confidence.[1]

Software discovery is being rewritten by machines.
Buyers no longer scroll a review site; they ask an assistant. But assistants are being handed the same data humans were: solicited star-ratings on sites funded by the vendors they rank. That model was gameable before AI. Now it's a liability.

You can't out-review the incumbents. You can out-trust them.
Every fact carries provenance
Source, retrieval date, and a confidence band travel with every value, so an agent can cite the evidence, not just the claim.
No vendor money touches the data
Vendors can claim and correct their profile, but they can never buy rank. Independence is the one thing the incumbents can't copy.
Structured before prose
The canonical form of a comparison is data. Prose, JSON-LD, and markdown are all projections of it, never the reverse.
Revealed preference, not reviews
We score real adoption and developer activity: downloads, release cadence, security posture. Vanity metrics like stars count for little.
See the working, not a five-star average.
Every score decomposes into weighted, independently-sourced signals with an explicit confidence band. Here is a real profile from the knowledge core, rendered exactly as an agent would read it.
A confidence-weighted blend of independent signals: real adoption and developer activity, not stars or solicited reviews. Every input is dated and sourced.

The same canonical entity, dereferenceable however your agent speaks: JSON, GraphQL, clean markdown, or a single MCP tool call. No scraping, no HTML parsing, and a citation in every response.

As software discovery moves from clicks to answers, the winner isn't the biggest pile of reviews; it's the source AI reaches for and trusts. We're building that source, one verifiable fact at a time.
