Linkup vs Valyu: AI search beyond the web

Valyu is a Linkup alternative for teams building AI that needs the web, specialist datasets and their own internal knowledge. It combines search across those sources with DeepResearch: an API for turning research instructions into cited reports and structured outputs. Linkup offers web search, research and private indexing too. Choose Valyu when research needs specialist and licensed data alongside the web, then turn that evidence into repeatable research jobs.

Linkup vs Valyu at a glance

Better research starts with better sources

Knowledge workers do not rely on Google alone. Their AI should not either.

A company announcement is useful. So are the filing behind it, the financial data that puts it in context and the research that challenges it. In science, an abstract may omit the methods or results table that determines whether a finding applies.

Valyu makes these sources searchable through one API: SEC filings, market data, academic literature, clinical trials, patents and licensed content. Some are public but difficult to retrieve reliably through general web search; others require licensed access. For example, Wiley Health & Life Sciences provides full-text passages from subscription and open-access journals, with access enabled per organisation.

For enterprise knowledge work, this means an agent can investigate the underlying evidence instead of relying on whatever is easiest to find on the web.

Turn a research process into repeatable jobs

Valyu DeepResearch lets teams specify what to investigate, which sources to use and how to structure the result. It runs the searches, analyses the evidence and returns a cited report or structured data.

Consider a private equity team screening acquisition targets. A reusable research brief could be:

For each target, map its products, customers and competitors. Check company claims against filings and current reporting. Apply our investment criteria, flag conflicting evidence and return a cited screening memo with open diligence questions.

The team can submit the same brief for each company, attach relevant documents and feed completed results into its own tools using webhooks. Analysts review the findings rather than rebuilding the research process for every target.

That is how a firm's research playbook becomes software: codify the questions and evidence requirements once, then run them across a pipeline or portfolio.

Keep the live web in the research loop

Valyu combines real-time web search with page extraction, so research can incorporate current announcements and reporting alongside specialist datasets. For a diligence job, that could mean checking a company's latest product page against an older filing.

Freshness depends on the source. Live web retrieval and periodically refreshed specialist indexes serve different purposes. Valyu brings both into the same research workflow.

Bring the firm's knowledge too

Valyu's enterprise offering includes private indexes for internal documents, custom vertical indexes and Forward Deployed Engineers who build around a team's workflow. An investment agent can use past memos and portfolio reporting; a scientific agent can use lab notebooks and internal research.

Enterprise options include Zero Data Retention, SSO, regional deployments and dedicated VPC deployments. The objective is to combine a firm's own knowledge with external evidence in the tools its people already use.

Trusted by AI startups and enterprises

From AI startups building research products to enterprises scaling knowledge work, teams use Valyu to give their AI access to the evidence it needs.

Which should you choose?

Linkup is worth evaluating for web search, cited research and private indexing. Choose Valyu when the job calls for specialist and licensed data alongside the web, your firm's own knowledge, and repeatable DeepResearch workflows.

Test it on a real assignment: check whether it finds the required sources, supports its claims and returns something the team can use.
