Legal research
Perplexity with careful prompts saves a lot of research time and finds key cases quickly, though hallucinations remain possible so cites must still be checked and Shepardized.
The author received a near-final legal document from a lawyer containing poor-quality Perplexity-generated content and objects to lawyers relying on AI.
Describes a workflow using Perplexity for research, Claude for reviewing citations and quotes, and Lexis for pulling and Shepardizing cases, while stressing that human verification remains necessary.
Finds that the Claude model running inside Perplexity gives more concise and better-reasoned output, and uses Cowork for larger drafting and agentic tasks.
Recommends Perplexity Enterprise Pro for law firms because it offers zero data retention and audit trails at a lower price, protecting the lawyer's license.
Finds no legal research tool that beats Perplexity when it is given the right legal sources, but warns commercial LLM prompts may not be protected by privilege and client matters should use self-hosted models.
Comet/Perplexity retrieved a case from the agency site when Lexis blocked the download, which might one day reduce reliance on Lexis, though this is only one anecdote.
A transactional lawyer reviews contracts against a written playbook in Perplexity and Gemini projects, but must apply changes manually in Word and watch confidentiality.
ChatGPT is wrong for case citations, while Perplexity works better for cursory research like an enhanced search, but all AI tools need close supervision because they get things wrong.
Uses Perplexity to find authoritative citations faster than Lexis, but says it is a shortcut, not a substitute for research, and every source must be run down to primary authority.
A self-represented small claims litigant says asking Perplexity legal and procedural questions gave them the confidence to bring their own case and did much of the legwork.
The author used Perplexity Deep Research to compile a fifty-state table of local laws, tax rates and legal obstacles, found it as good as OpenAI's tool without the CSV download problems, and recommends it.
Perplexity helps lawyers dig out relevant source material and take shortcuts through large volumes of text, though its results still need to be cross-checked.
AI tools are decent for basic letters and discovery brainstorming but produce errors on nuance; Perplexity beat the costly Westlaw AI, which the author stopped using.
