Paralegals cost $62,890 a year on average. The job market isn't growing to meet demand. Case managers at PI firms are already stretched across intake, status calls, and case files.
AI paralegal platforms exist to absorb that overflow. They pull records into timelines, draft discovery, and summarize depositions — work that used to take days. None of them do everything, and picking the wrong one wastes a budget cycle.
This guide covers five platforms doing real work inside PI firms right now. Each one owns a different slice of the caseload: calls, case-wide AI, depositions and records, discovery, and research. We'll walk through what each does, what it costs, and who it fits.
AI adoption in legal isn't a future bet anymore. More than half of legal consumers now turn to AI first, per Clio's 2026 Legal Trends Report.
Firms that build an AI paralegal stack early aren't just saving hours. They're keeping pace with how clients already expect to be served.
What are the best AI paralegal platforms for PI firms in 2026?
Every firm's bottleneck looks different, so the right platform depends on where your team is actually losing time. HelloCounsel resolves the operational calls that eat case manager hours before anything reaches a paralegal's desk. Supio runs agentic AI across the full case lifecycle, from intake through case economics.
CaseMark AI turns depositions and medical records into structured summaries a paralegal would otherwise build by hand. Briefpoint.ai drafts discovery requests and responses at a flat monthly rate, with no per-case billing. Trellis.law pulls judge analytics and verdict data from state trial court filings for case valuation.
That range in scope means a range in cost, too. A single-workflow tool like Briefpoint runs a predictable flat fee. A full-lifecycle platform like Supio needs a custom quote built around your caseload.

1. HelloCounsel: The AI that clears calls before they ever reach a paralegal
Quick note: We're the team behind HelloCounsel. We think it belongs on this list, but we'd say that either way — weigh it against your own call volume.
A PI case generates roughly 150 calls before it closes. Most of those calls — status checks, lien balances, records confirmations — never needed a paralegal. They just needed someone, or something, to resolve them and log the outcome.
HelloCounsel is an AI voice agent built specifically for PI, comp, and mass-tort call volume. It's not a paralegal tool in the traditional sense. It's the layer that keeps routine calls from becoming paralegal work at all.
Missed calls carry a real cost too — a potential client walking to the next firm in search results.
What it handles
HelloCounsel answers every inbound call 24/7 — existing clients, vendors, insurers, medical providers, and lien holders. It resolves routine requests without escalating them to a human. Call transcripts and summaries write into the case file in Filevine, Litify, and Clio.
The platform also surfaces operational data most firms have never had: unanswered clients, time-leak diagnostics, and case-cycle metrics.
Pricing snapshot
Pricing is custom, based on call and case volume, and requires a demo to get real numbers. A 2-week free pilot comes with a custom ROI estimate built from your firm's own call data.
Strengths and gaps
The core strength is resolution, not routing — HelloCounsel closes out routine calls instead of sending them back to a human. That matters most for the post-intake volume that consumes case manager workload: vendor pings and provider follow-ups. The trade-off is scope — it's built for RingCentral phone stacks and isn't designed for solo practitioners.
Firms on a different phone stack should confirm compatibility before signing anything.
Who's actually using it
Mid-market PI firms with 10 to 200 employees, dedicated case managers, and an active CMS like Filevine or Litify. Firms where case managers log 50+ hours a week on status calls see the clearest fit.
2. Supio: Agentic AI across intake, chronologies, and case economics
Supio was built for the moment PI firms stopped wanting a single-purpose tool. Instead of one product for chronologies and another for demands, Supio runs agentic AI across the case. It spans intake, records, drafting, and case-level financial analysis in one system.
The company has raised $85 million from Sapphire Ventures, Mayfield, Bonfire Ventures, and Thomson Reuters Ventures. It's used by hundreds of PI and mass tort firms, including TorHoerman Law. The firm cited Supio in building a $495 million Abbott Labs verdict.
What it handles
Supio's platform spans intake conversion, AI-generated medical chronologies, demand letter prep, and litigation drafting. A case economics layer tracks case value and financials as a running ledger. A firm-level intelligence tool analyzes patterns across the whole caseload, not just one file.
Pricing snapshot
Supio offers two models: a case subscription, and unlimited firm access covering every case under one fee. Both include unlimited users and pages. The company says it avoids lock-in contracts, but exact figures require a demo.
Strengths and gaps
The breadth is the differentiator — few platforms touch intake, records, drafting, and case economics in one system. Supio integrates with Litify, SmartAdvocate, MyCase, CASEpeer, and Smokeball. Filevine and Clio aren't listed among its published integrations, so firms on either system should confirm compatibility first.
That breadth is also the risk — switching vendors later means a heavier lift.
Who's actually using it
Mass tort and multi-attorney PI firms managing high case volume across several workflows at once. Firms already comfortable handing case-level financial analysis to an AI system will get the most from it. Firms wanting a single vendor across the entire case lifecycle are the clearest fit.
3. CaseMark AI: Deposition summaries and medical chronologies built for litigation
Reviewing a deposition or a stack of medical records eats entire days of paralegal time. CaseMark is built to compress that timeline. The company says it can go from raw discovery to a draft motion in under an hour.
Over 7,000 attorneys use the platform, including firms like Nelson Mullins and Ogletree Deakins. CaseMark is backed by Gradient, Lerer Hippeau, and Cambrian.
What it handles
The core product is a workspace for researching and drafting against case files, layered with structured summaries. Those summaries include deposition recaps and medical chronologies with cited timelines.
A companion tool called Source handles branded file delivery for litigation support teams. A separate API platform, case.dev, exposes 18 of these services for firms building custom tools.
Pricing snapshot
The Pro plan runs $100 per user per month. It includes $80 in monthly AI credits and access to 880+ legal agent skills. Team and Enterprise tiers require contacting sales, and Enterprise adds a signed BAA.
Strengths and gaps
Medical chronologies and deposition summaries make this a strong fit for record-heavy PI litigation. The per-user pricing is unusually transparent for the category. The gap: the homepage doesn't document Filevine or Litify integrations, so verify that directly before buying.
The 880+ agent skills library also means a learning curve for firms new to configurable AI tools.
Who's actually using it
Litigation-heavy PI and mass tort teams that process large volumes of depositions and medical records. Firms that want transparent, seat-based pricing over a custom quote will appreciate the published Pro tier. Solo practitioners handling occasional PI cases may find the per-seat cost hard to justify.
4. Briefpoint.ai: AI discovery drafting at a flat monthly rate
Discovery is one of the most repetitive tasks in PI litigation — interrogatories, requests for production, and the responses to both. Briefpoint drafts them from the complaint and a client questionnaire, then formats a Bates-cited production package ready to serve.
More than 1,000 users across all 50 states rely on the platform. That includes plaintiff firms, defense counsel, and in-house teams.
What it handles
Briefpoint generates 70+ targeted discovery requests directly from complaint allegations. It collects client responses through a secure portal, available in English and Spanish. It matches responsive documents to requests, applies Bates numbering, and manages supplemental responses when facts change.
Discovery playbooks enforce consistent objection strategy across every case in the firm.
Pricing snapshot
The Rainmaker Plan is a single flat rate: $150 per attorney per month, billed annually at $1,800 a year. There are no per-case fees and no tiers. Every firm pays the same rate regardless of case volume.
Strengths and gaps
Flat pricing is the standout feature in a category usually priced per document or per case. The trade-off is scope: Briefpoint drafts and manages discovery specifically. Firms still need a separate tool for chronologies, demand letters, or intake.
That makes it a strong add-on to a broader platform rather than a full replacement for one.
Who's actually using it
High-volume plaintiff and defense litigation teams drowning in repetitive discovery paperwork. One user described finishing full RFP and RFA drafts in under an hour. That's a job that usually eats a full day.
5. Trellis.law: AI litigation research for case valuation and strategy
Valuing a PI case well means knowing how a judge rules. It also means knowing what similar cases settled for, and how opposing counsel litigates. Trellis makes that data searchable, pulling from state trial court filings nationwide.
The platform isn't built exclusively for personal injury. Litigators in any practice area can use its judge and case analytics for strategy.
What it handles
Trellis indexes state trial court documents and layers judge analytics on top. Case strategy reports support early assessment for newly filed matters, and attorney analysis surfaces patterns in how opposing counsel litigates. Alerts and trackers flag new filings automatically.
That judge-by-judge view — how a specific judge tends to rule on similar motions — is difficult to reconstruct manually.
Pricing snapshot
Trellis doesn't publish pricing. The platform targets firms, insurers, and in-house teams that need ongoing access to trial court data. That usually means a custom quote after a demo.
Strengths and gaps
The judge-level analytics are hard to replicate by hand, taking a paralegal days per judge. The gap is specificity. Trellis serves every practice area, so PI firms won't find case-type filters built exclusively for them.
Firms already paying for Westlaw or Lexis research tools should weigh the overlap before adding a third subscription.
Who's actually using it
PI firms and insurers that need data-backed strategy before deciding whether to settle or litigate. Firms building a demand or valuing a case get the most use from the judge and verdict analytics. Firms without a litigation research budget may find the general-practice pricing steep for occasional use.
Frequently asked questions
What exactly counts as an "AI paralegal platform"?
It's software that automates paralegal work: chronologies, discovery drafting, deposition summaries, and legal research. None of the platforms above replace legal judgment. They compress the hours spent preparing material an attorney reviews before it goes out.
Will these tools replace human paralegals at PI firms?
Unlikely, at least not entirely. Paralegal openings aren't disappearing — the BLS still projects roughly 40,800 a year, mostly from people leaving the field. What's changing is the ratio — one paralegal supervising AI can cover work that used to take two or three people.
How does the cost compare to hiring another paralegal?
A paralegal costs roughly $62,890 a year in salary alone, before benefits and overhead. Every platform on this list costs less than that per year on its own. Most firms adopt one or two, not all five, based on where they're losing the most hours.
Can these platforms write into Filevine, Litify, or other PI systems?
It varies by platform and changes often, so confirm directly before buying. Supio lists Litify, SmartAdvocate, MyCase, CASEpeer, and Smokeball, but not Filevine or Clio. CaseMark and Briefpoint don't publish a CMS integration list, so ask before signing.
Is AI-drafted discovery or a chronology safe to send without review?
No. Every platform here produces a draft, not a final work product. Attorney review before anything reaches opposing counsel or the court is non-negotiable, no matter how good the draft looks.
Do PI firms need to run all five platforms at once?
No. Most firms run one or two tools tied to their biggest bottleneck. They add a second tool once the first is paying off. Stacking every category at once usually means half of it goes unused.
How fast can a PI firm get one of these platforms running?
Discovery and call-handling tools tend to move fastest — Briefpoint and HelloCounsel can both be live within days. Full-lifecycle platforms like Supio take longer, since onboarding means connecting your CMS and training the system on firm templates.
Where should a PI firm start building an AI paralegal stack?
Start with whichever workflow is costing the most hours right now, not the one that feels most exciting. A firm buried in discovery gets more from Briefpoint than from a research tool it barely opens. Firms with case managers fielding 50+ hours of status calls a week should see what's driving that volume first.
Conclusion: matching the platform to where your firm actually loses time
Solo and small PI firms without dedicated case managers get the most relief from a flat-rate tool like Briefpoint. One clear workflow, one predictable bill. Mid-market firms with busy case managers should start with the call volume itself — usually the largest hidden cost.
Mass tort and high-volume litigation shops lean toward broader platforms like Supio or CaseMark AI. These span records, drafting, and case-wide intelligence in one system. Firms building a demand or deciding whether to settle need the judge and verdict data Trellis surfaces.
A paralegal can't reasonably compile that by hand, at least not on a Friday afternoon deadline.
Most platforms here require a demo before you see real pricing, and HelloCounsel adds a free pilot on top. Use that window to run one real case through the tool before rolling it out firm-wide. A platform that looks great in a demo can still stumble on your firm's actual intake volume.
No single platform replaces a paralegal's judgment, and none of them are betting that it should. Each one is built to clear repetitive work off a paralegal's desk so judgment calls get the attention they deserve.
If operational call volume is where your firm loses the most hours, that's the workflow to fix first. Book a 2-week free pilot and see what resolves in your first two weeks. No commitment, no long onboarding — just real numbers from real calls.
