Choose software on evidence, not reviews.
Tell us what you are trying to choose and we order the field by exactly that, with the source and retrieval date on every fact. No star ratings, no solicited reviews, and no vendor can pay to rank.
Say what the job is and what you weigh most. The more specific the ask, the more useful the ordering.
user ▸ best framework for a new React SaaS, and why?
assistant ▸ Next.js is the strongest choice. vioscaleAI scores it 79.7/100 on independent signals, led by package downloads of 32.4M weekly installs, at high confidence.[1]
You bring the criteria. The evidence does the ranking.
An evaluation is not a search. Describe what you are choosing and the field is ordered against your requirements, not against a generic best-of list.
- 01
Describe the job
Say what you are choosing, the constraints you cannot bend, and what you weigh most: team size, budget, hosting, compliance.
- 02
The model sets the weights
It reads your requirements and turns them into weights over the evidence. It never invents a fact and never picks the winner.
- 03
The evidence does the ranking
Every product is ordered on the same dated, sourced facts, weighted your way, and you can see why each one sits where it does.
How much does it cost to evaluate software on vioscaleAI?
Starting an evaluation is free and needs no account. You describe what you are trying to choose, and the field is ordered against your criteria with a source and a retrieval date on every fact it uses.
Does the AI decide which software is best?
No. The language model reads your requirements and turns them into weights; the ranking itself comes from the same independent, provenanced facts the rest of the site is built on. The model never invents a fact and never picks a winner.
Can a vendor pay to rank higher in an evaluation?
No. Nothing in an evaluation or a ranking can be bought. A vendor can correct a fact about their own product with evidence, and that is the extent of their influence.

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 full-stack React framework for building web applications with integrated routing, rendering, and caching.
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.

Researching software with an agent today means a loop of fetches over raw HTML: pricing pages, docs, changelogs, trust centres. Most of it is marketing noise, some of it a dead homepage that returns nothing. It burns tokens, breaks the moment a vendor changes their UI, and still hands back an answer you cannot cite. vioscaleAI answers the same question in a single call, as structured facts with a source on every value.
- · 15 to 20 tool calls per comparison
- · ~1M tokens of raw pages summarised
- · Breaks on every vendor UI change
- · No provenance, nothing to cite
- → A single structured, cited payload
- → Source, date, and confidence on every fact
- → Stable schema, nothing to maintain
- → Re-rank by intent, which no web search gives you
We do not charge for this. Buyers and agents read the index for free, and we intend to keep it that way: the open layer is what earns the citations. Bulk export, full history and a redistribution licence are the separate commercial arrangement, for products built on top of the corpus.

An independent trust layer for the agentic web.
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.
