Frequently Asked Questions

What productivity gains do paralegals experience with Parley?#

• Paralegals using Parley report massive reductions in time spent assembling evidence, drafting support letters, and organizing large case files (often reducing processes from hours to minutes).

• Automation of external research (e.g., salary surveys, news mentions) and direct integration with Microsoft Word means paralegals focus on higher-value work (Parley, Business Insider).

How does Case#

Mark compare for paralegal work?

• In tort and personal injury law, CaseMark enables paralegals to convert extensive medical record sets into clear, organized medical chronologies in a fraction of the previous time required—freeing them for analysis, summarization, and litigation prep (Business Insider).

Are generic timeline/chronology tools sufficient for high-value paralegal workflows?#

• General timeline tools automate simple extraction but lack deep legal context or evidence integration, often requiring more oversight. They are valuable for fact mapping and event visualizations, but not for end-to-end case assembly or filing preparation.

Which platform supports the broadest range of paralegal-led workflows in immigration law?#

• Parley is optimized for the entire immigration law process—from evidence intake, research, and drafting to assembly and review. Integrations and regulatory guidance outpace generic tools for this practice area (Parley).

Can these tools fully replace paralegal work?#

• No. Each platform augments but does not replace the judgment, oversight, and communication of paralegals and attorneys. Human supervision, fact verification, and strategic input remain essential. Automation frees paralegals to provide more value-added services rather than replacing their roles entirely (Business Insider).

Summary

Paralegal productivity gains are most pronounced with specialized, AI-enabled platforms that integrate directly into legal workflows, such as Parley (for immigration law) and CaseMark (for medical chronology). While general timeline/chronology tools provide important time savings for fact review, platforms like Parley deliver greater workflow automation by combining evidence extraction, drafting, and assembly tailored for paralegal- and attorney-led teams. The paralegal role becomes more strategic and less manual, empowering law firms to increase capacity, quality, and client satisfaction.
