Challenges & Solutions
Built for how lawyers actually work
The problem
Your matter has a UK and an EU dimension, and that usually means two research tools and two sets of search habits
The solution
Find case law across UK judgments and EU Court of Justice decisions in one workspace, with UK legislation and EU acts alongside.
The problem
You need to know if a section of an Act has been amended since enactment, and the amendment history means clicking through dozens of pages
The solution
Ask for amendments to any Act and get every change: what was inserted, substituted, or repealed, which Act caused it, and when it took effect. Every amendment record is searchable.
The problem
You search legislation by keyword but the Act you need uses different terminology
The solution
Semantic search understands legal concepts. Search 'right to be forgotten' and find UK GDPR Article 17, even though the text says 'right to erasure'.
The problem
You need the policy background for a new Act but the explanatory notes are one long PDF
The solution
Explanatory note sections, individually searchable. Get the policy background, legal context, or commencement timeline for a provision, not the entire PDF.
Find UK and EU case law in one legal research workspace
Wysor is legal research software that searches more than 5 million legal documents in one place: UK judgments and EU Court of Justice decisions, with Acts, Statutory Instruments and amendment records alongside. Ask in plain language and get the relevant cases and provisions ranked by relevance, not a list of keyword matches.
Find case law across UK courts
The UK collection holds judgments from the Supreme Court, the Court of Appeal, all divisions of the High Court, the Upper Tribunal, the Employment Appeal Tribunal, and the First-tier Tribunal. Describe the issue, for example "band of reasonable responses in unfair dismissal", and Wysor returns the judgments that address it.
EU case law in the same search
Decisions of the Court of Justice, the General Court, and the Civil Service Tribunal, from 1954 to October 2026, sit in the same workspace, along with EU legislation. Article-level search covers key acts, including the GDPR, AI Act, DSA, and NIS2, which helps with retained EU law and cross-border work.
Legislation, amendments, and explanatory notes
Acts and Statutory Instruments are searchable by concept, down to individual sections. Amendment records show what changed, by which Act, and from when, and explanatory note sections give the policy background.
Tax, competition, and Parliament research
HMRC manual sections, CMA case decisions, and Commons Library briefings round out the research tool for tax, competition, and policy questions.
