For defense attorneys, paralegals, investigators & mitigation specialists
AI-assisted mitigation platform for criminal defense.
Aperio helps solo and small defense firms — attorneys, paralegals, investigators, and mitigation specialists — build a stronger mitigation strategy in less time per case.
You are the only defense attorney in the firm, with one paralegal beside you. Mitigation is the work that moves sentences, and it's the work that gets squeezed first when discovery, hearings, and client calls fill the day.
Every case you accept has a real time cost, so the calendar caps your practice before demand does.
Records, history, and context that could change a sentence stay buried because nobody has the hours to dig.
After sentencing you replay it: did I fight hard enough for this client's freedom?
A platform built around the mitigation work criminal defense teams already do, with AI handling the reading, sorting, and drafting. It works for the whole team: attorneys, paralegals, investigators, and mitigation specialists in the same case file.

Aperio never provides legal advice and never suggests legal action. It organizes, analyzes, and drafts mitigation material. Every legal judgment stays with you.
Client material lives in a dedicated case workspace and is never used to train public models — unlike pasting records into a consumer AI chatbot.
General LegalTech tools are built around discovery and research. Aperio is built around mitigation domains, life history, and sentencing materials.
Every narrative is a draft for your review, with gap flags and source records behind it, so nothing goes out that you haven't verified.
The reading and drafting that used to eat evenings gets done in a working session, so your hours go to strategy and clients.
When mitigation stops being the bottleneck, your firm can take on the cases you're currently turning away.
You walk in with the client's full history documented, not the version you had time to assemble.
You know what was found, what was argued, and that nothing was left on the table.
Aperio comes out of mitigation specialist and investigation work — sitting with families, pulling records, and building the history that judges and prosecutors never see otherwise. We watched good attorneys run out of hours before they ran out of facts, so we built the tool we wanted on those cases.
