Two callers never show up in a PI firm's marketing reports: the insurance adjuster and the lien holder. Neither one is a prospect. Both decide how fast a case moves and how much the client keeps.
Those calls are also some of the most repetitive work in the building. A typical PI case generates about 150 calls over its lifetime. A case manager carrying 100 to 150 cases fields 15,000+ calls a year, and most are status updates.
This guide compares five AI phone agents on that specific work. We looked at outbound calling, phone-tree navigation, case file write-back, compliance, and price.
Some tools are built for plaintiff firms. Others are platforms your team has to configure.
The short version: five agents compared
HelloCounsel resolves adjuster and lien holder calls and writes each one into the case file. Lexafide focuses on claim opening and adjuster follow-up for plaintiff firms. Retell AI, Bland AI, and Synthflow are configurable voice platforms, so your firm builds the adjuster workflow itself.
The right pick depends on who owns the build. A firm with no developer should favor a product that arrives pre-configured for PI. A firm with an engineering partner can start lower on price and own more of the stack.

How we compared these agents
Adjuster and lien holder calls are not intake calls. The agent usually makes them, and the other side is a business with its own phone tree. We scored each tool on four things.
First, can it place outbound calls and keep trying until it gets an answer? Second, can it get through menus, holds, and voicemail?
Third, does the outcome land in the case file without retyping? Fourth, what does it cost once volume reaches a real PI caseload?
Ratings come from public G2 pages, and pricing comes from vendor pages checked in November 2026. Where a vendor publishes nothing, we say so. Please confirm current terms before you sign.
1. HelloCounsel: Resolves the call, then writes it into the case file
Heads up: HelloCounsel is our product, so we have a stake in this ranking. We placed it first because of its PI focus. Still, test every option against your own call mix.
HelloCounsel builds AI agents for plaintiff firms. They answer calls, open cases, chase medical records, and keep clients updated. They work by phone, text, email, fax, and provider portals.
That scope matters for adjuster and lien holder work. A carrier calls for a status, or a provider's billing office confirms a balance. HelloCounsel resolves those calls from the case file instead of taking a message.
Compared with the platforms below, it arrives pre-configured for PI. Your team does not write scripts or build lien logic from scratch.
How it handles adjuster and lien holder calls
The Receptionist agent answers in under two rings, including after hours and on holidays. It matches the caller ID to the case file and routes the call to the right person. It also answers status questions straight from the file.
Outbound work is where adjusters come in. Once the fee agreement lands, the Case Opening agent collects insurance cards and driver's IDs and pulls the police report.
It then calls the carrier until it has the claim number. It checks what the file is missing and follows up until the file is complete.
Lien holders are mostly medical providers, and those calls follow predictable patterns. Records status, balance confirmations, and authorizations all repeat.
The Medical Records agent works provider phone systems through menus, hold music, and redials until it reaches the records custodian. Our guide to medical provider calls covers that workflow in more depth.
Every attempt gets logged to the case file with no copy-paste. That is what native CMS write-back means in practice. A dashboard then tracks every call, task, and agent across the firm.
Pricing and setup
Pricing is custom and based on the firm's call and case volume. It is not per seat or per agent. The site says firms "only pay for the tasks agents complete."
Most firms go live in under two weeks from the first call. Integrations include Filevine, Litify, SmartAdvocate, MyCase, CASEpeer, LeadDocket, and Lawmatics. The sales process starts with a demo call with the founders.
Strengths and trade-offs
Pros: It handles both inbound and outbound adjuster and lien holder calls. It writes every attempt into the case file. Customer data is never used to train agents, and that promise is written into the MSA.
Cons: There is no public price list, so you need a demo to get a number. It is built for plaintiff-side practices, so general practice firms will find it too narrow.
Who's using it
Named customers include Cerchione Hurowitz Law Group, Pendergast Law, Martin Jones & Piemonte, and Farris, Riley & Pitt. The site reports 30,000+ calls handled. Anthony Ramos, COO at Pendergast Law, calls the experience "outstanding."
2. Lexafide: Claim opening and adjuster follow-up for plaintiff firms
Lexafide Inc. was founded in 2025. The LawNext Directory describes it as "AI agents built for law firm operations" for plaintiff-focused firms. Listed capabilities include intake, call reception, claims opening, case management, and adjuster communications.
It is the closest match to HelloCounsel on carrier-facing work. It is also much younger, and its public documentation is thinner. Treat it as a promising specialist you need to vet closely.
What it does on the call
A September 2026 LawNext report covers a vendor press release. It says Lexafide opens new motor vehicle accident claims and follows up on PIP and IME requests. The agents work through each carrier's own intake process and act as "chasers" on existing claims.
The directory also lists outbound calling, bilingual services, and text messaging. It does not mention lien holders, medical providers, or records work. Ask the vendor directly whether those calls are in scope.
Pricing and setup
Lexafide does not publish pricing. The directory listing names no case management integrations either. Before you buy, confirm which systems it writes into and whether notes land in the case file automatically.
Strengths and trade-offs
Pros: The workflow is aimed squarely at carrier claim opening. Reported results include a claim number secured on every claim in the month the report covers. The product is built for plaintiff firms rather than adapted from a generic receptionist.
Cons: No published pricing, no listed integrations, and no described lien workflow. Every performance figure comes from the vendor.
Proof and track record
The LawNext report names Richmond Vona, a PI firm in Buffalo, New York. In one month, the firm reports 11 new motor vehicle accident claims opened. Those claims spanned 8 carriers, including State Farm, Progressive, and GEICO.
It also reports 23 follow-up requests for PIP ledgers and IME reports, each tracked to resolution.
The directory adds vendor claims of a 60% cut in reception call volume and 95%+ routing accuracy. None of these figures has been independently verified.
3. Retell AI: A configurable platform with phone-tree navigation
Retell AI is a developer-friendly voice platform used across many industries. It is not legal-specific. You or a build partner design the adjuster and lien holder workflow on top of it.
That trade has real upsides. You control the scripts, the logic, and the data flow. You also carry the build and the maintenance.
Core features
Retell's batch calling runs high-volume campaigns. You upload an audience, schedule the campaign, and control pacing and retries. For adjuster work, that could mean a daily sweep of open claims.
Its Navigate IVR feature detects phone menus and presses digits during live calls. Carrier and provider lines are full of menus, so this matters. Call transfer lets the AI brief a human and confirm readiness before connecting the call.
Branded call ID and verified phone numbers help avoid spam flags. Webhooks and an API are included. Listed integrations include Make, Twilio, Vonage, Go High Level, and n8n.
What you'll pay
Voice agents run $0.07 to $0.31 per minute. Telephony adds $0.015 per minute, and batch calling adds $0.005 per dial.
Pay-as-you-go includes 20 concurrent calls. Signup comes with $10 in free credits.
Billing runs to the second, and you are charged during silence or hold time. That detail matters for carrier calls, where holds are common. Enterprise plans add a custom MSA, DPA, and BAA.
Pros and cons
Pros: Published pricing makes cost modeling easy. Retell says it is compliant with HIPAA, SOC 2 Type II, GDPR, and ISO 27001. Phone-tree navigation fits adjuster and provider calls well.
Cons: There is no PI workflow out of the box. There is no native write-back into Filevine or Litify, so someone must build it. Hold time is billable, and your team owns script quality.
Customer base and ratings
Retell holds a 4.8 out of 5 rating on G2 from 2,644 reviews. The reviews cover many industries. Its site names no PI firm case study, so ask for legal references before you commit.
4. Bland AI: Enterprise controls for firms with an in-house builder
Bland AI is another general-purpose platform for building phone agents. It leans toward enterprise buyers with strict security needs. A PI firm would use it like Retell: build the adjuster workflow, then connect your systems.
What it offers
Bland's per-minute rate covers the language model, speech-to-text, and text-to-speech. Telephony is billed separately. Higher tiers raise concurrency and daily call caps.
Custom dialing appears only on the Enterprise plan. The pricing page does not describe batch calling, so confirm how outbound sweeps would work. On-premise and VPC deployment are available on Enterprise.
Pricing breakdown
The Start plan costs $0.14 per minute of talk time and $0.05 per transfer minute, with no platform fee. It allows 10 concurrent calls and 100 calls a day.
The Build plan costs $0.12 per minute plus $299 a month. It allows 50 concurrent calls and 2,000 calls a day. Enterprise is custom.
Where it shines (and where it doesn't)
Pros: Bland lists SOC 2 Type I and Type II, plus HIPAA with a BAA. It also lists GDPR, ISO 27001, and FedRAMP 20x Class A. On-premise deployment suits firms with strict data rules.
Cons: The BAA, custom dialing, and data residency all sit on Enterprise. There is no PI workflow and no native write-back. The pricing page does not mention legal or insurance use cases.
Notable users and ratings
Bland holds a 5.0 rating on G2, but that rests on just 11 reviews. Treat the rating as thin evidence. The pricing page names no law firm customers.
5. Synthflow: Enterprise contracts with security paperwork ready
Synthflow sells voice agents through annual enterprise contracts. Each contract is scoped to call volume, phone system, integrations, and security needs. It fits larger firms that want procurement-ready documentation more than a quick pilot.
Key features
Synthflow offers native telephony, SIP trunking, or approved enterprise telephony. CRM, calendar, and contact-center connections are scoped into the contract. Its site names Five9 and Zoom among its integrations, and it supports webhooks and an API.
The pricing page does not mention outbound campaigns. Confirm that capability before you plan an adjuster sweep. Also ask how it would write into your case management system.
What the contract looks like
There is no free plan, trial, or published per-minute rate. New deployments start on an enterprise contract. Pricing comes from a sales conversation.
The package includes MSA and DPA support, data handling review, and enterprise security review. A Trust Center holds further compliance details.
Pros and cons
Pros: Synthflow lists SOC 2 Type 2, ISO/IEC 27001, HIPAA, and GDPR. Custom concurrency planning suits larger call volumes. The contract process is built for security-conscious buyers.
Cons: No public pricing and no trial make early testing harder. It has no PI workflow and no native case file write-back. Firms must scope outbound capability themselves.
Customer base and ratings
Synthflow holds a 4.5 out of 5 rating on G2 from 1,016 reviews. The page names no law firm customers. Ask for plaintiff-side references during evaluation.
Frequently asked questions
Can an AI phone agent really call an insurance adjuster?
Yes, though the depth varies by product. HelloCounsel's Case Opening agent calls carriers until it has the claim number. Lexafide reports opening claims through carrier intake processes.
Retell can navigate phone menus, but your team builds the claim workflow.
Is it legal for AI to make these outbound calls?
The FCC has ruled that AI-generated voices count as "artificial" under the Telephone Consumer Protection Act. That matters most when an agent calls clients or claimants on mobile phones.
Adjuster and provider lines are business numbers, but the rules vary. Ask your counsel to review the call flow, since this is not legal advice.
How are lien holder calls different from adjuster calls?
Adjuster calls usually chase a claim number, a coverage answer, or a status update. Lien holder calls confirm balances, payoff figures, and records.
Many lien holders are medical providers, but government payers matter too. Medicare's recovery program pursues mistaken primary payments in liability, no-fault, and workers' compensation claims.
An AI agent can read a balance from the case file and confirm it. Negotiating a reduction should stay with your team.
Do these tools write notes into Filevine or Litify?
HelloCounsel writes every call and attempt into the case file natively, with integrations for Filevine, Litify, and others. Retell, Bland, and Synthflow connect through webhooks, APIs, or contract-scoped integrations, so you build the write-back.
Lexafide's listing names no integrations. Ask each vendor to show a call landing in your own system.
Should we build on a platform or buy a PI-specific agent?
Build only if you have engineering capacity and a reason to own the stack. You will write scripts, handle edge cases, and maintain the integration. A PI-specific agent trades some control for speed.
The pressure to move is real. An Insurance Journal research paper says plaintiff firms use AI to reach claimants faster than carriers respond. A vendor authored it, so read it with that in mind.
What does a platform build really cost at PI volume?
Run an illustrative example. Say an agent makes 500 outbound calls a month and each averages six minutes, including holds. That is 3,000 billable minutes.
On Retell's published rates, voice plus telephony lands between roughly $255 and $975 a month. On Bland's Build plan, 3,000 minutes at $0.12 plus the $299 platform fee comes to about $659, before telephony. Neither figure includes developer time, script upkeep, or the write-back integration.
What should the AI hand back to a human?
Keep judgment calls with your team. That includes coverage disputes, lien reductions, settlement discussions, and anything an adjuster frames as a dispute. The AI should confirm facts, collect claim numbers, and log outcomes.
A good agent escalates with context already loaded. The case manager should never have to ask the adjuster to repeat themselves. Test that handoff during your demo, because it shows how well the tool carries context.
How fast can each one go live?
HelloCounsel says most firms go live in under two weeks. Retell gives $10 in free credits at signup, so a developer can start prototyping the same day. Bland's Start plan needs no card.
Synthflow begins with an enterprise contract and a sales process. Lexafide publishes no timeline. A fast prototype is not the same as a production agent that logs into your case file.
What should we ask in a demo?
Ask the vendor to run a real adjuster call, not a scripted one. Ask what happens when the AI hits a phone tree, a hold, or a voicemail.
Then ask where the call outcome is logged. Finally, ask what it costs when volume doubles.
So which agent should handle your adjuster and lien holder calls?
A PI firm with 100+ cases per case manager on Filevine, Litify, or SmartAdvocate should start with HelloCounsel. It covers both adjuster and lien holder calls and logs every one. About 70% of calls don't require a human, so the question is who handles the rest.
A firm focused mainly on opening motor vehicle claims should evaluate Lexafide. Ask for integration details, pricing, and references first.
Firms with a developer or build partner can prototype on Retell AI at low cost. Its phone-tree navigation is a real advantage.
Bland AI suits firms that need on-premise deployment and enterprise controls. Synthflow fits larger firms that want a contract and a security review.
Want to see adjuster and lien holder calls resolved on your own caseload? Book a demo with the HelloCounsel founders. Bring one recurring workflow, and they will map it with you.
