Built for UK immigration practice

The compliance copilot for UK immigration lawyers

Marcus is a compliance-first AI copilot built specifically for UK immigration lawyers — not a generic legal AI, but a system that encodes the actual Home Office document requirements and deadline logic that make immigration cases so easy to get wrong.

What Marcus does

The work that fills an associate's week

01
Document requirement checks
Bundles read against the specified evidence for the route — missing months, expired certificates, mismatched names. The failure modes that cost a refusal are mechanical, and they get caught before submission.
PAYSLIPSTB CERTIFICATECoSENGLISH LANGUAGE
02
Deadline calculation
CoS validity, 28-day windows, appeal and administrative review limits, worked from the date of application.
03
First-draft representations
Cover letters and reps drafted in your firm's voice, with the Rule and guidance paragraph cited inline.
04
Client document chasing
Plain-English requests for what is actually outstanding, so files stop stalling on a single missing payslip.
05
Refusal and CoC review
Refusal notices read against the file to surface the ground actually taken and what the response needs.
06
Firm memory
Your precedents, your wording, your standing instructions — reused instead of re-explained on every matter. The second application on a route should never cost what the first one did.
Building the case

A copilot for the case, not a chatbot on the side

Marcus works from the matter itself. It builds the evidence position, holds the chronology, and shows what still has to be proved for the route you are applying under — so the case is assembled as you go rather than reconstructed the week before submission.

Requirement-by-requirement evidence map
Each requirement of the route is listed with the documents on file that satisfy it, what is partially met, and what is still outstanding. You can see the shape of the application at a glance.
Immigration history and chronology
Leave granted, gaps, absences, previous refusals and dependants, drawn out of the documents into one timeline you can rely on when drafting.
Weak points, before the caseworker finds them
Where a file invites a question — a shortfall against the salary threshold, an absence that touches continuous residence — Marcus flags it and sets out what evidence or explanation would answer it.
Reps that argue from the file
Representations drafted against the documents actually in the bundle, citing the Rule or Appendix relied on, ready for a fee earner to shape and sign.
Who maintains the rules

Controlled and managed by UK-regulated immigration lawyers

All UK Immigration Rules and Home Office requirements inside Marcus are written, reviewed and version-controlled by regulated UK immigration lawyers. The model does not infer the law from the open internet — it applies a rules bank that practitioners own.

01
Drafted by practitioners

Requirements for each route are encoded by IAA-regulated immigration advisers, not by engineers reading guidance.

02
Versioned by date in force

Statements of Changes are reviewed on publication and applied with effect from the date they take force, so historic matters stay correct.

03
Traceable to source

Every requirement links to the Rule, Appendix or caseworker guidance paragraph it came from, with the date it was last reviewed.

04
Nothing released without review

Changes to the rules bank go through legal sign-off before they reach a single matter.

How it works

Four steps, and a human at the end of all of them

STEP 01
Open the matter

Pick the route. Marcus loads the requirements and dates in force for it.

STEP 02
Drop in the file

Documents, correspondence, notes. Nothing needs renaming or reformatting first.

STEP 03
Read the findings

Gaps, dates and drafts, each one citing the Rule or guidance it came from.

STEP 04
Sign it off

A fee earner reviews and approves before anything reaches a client or the Home Office.

Security & compliance

Speed without the regulatory exposure

Every draft, document check, and deadline calculation is reviewed by a human before it goes anywhere. Marcus is built to sit inside your existing supervision arrangements, not around them.

UK data residency
Matter data stored and processed in the UK. No training on your files, ever.
IAA-aligned supervision
Human sign-off is a required step, logged against the matter with who approved what.
UK GDPR & Data Protection Act 2018
A data processing agreement is available on request, with a full record of processing and retention controls per matter.
Citations, not assertions
Each output points to the Rule, Appendix or guidance paragraph behind it, so it can be checked in seconds.
The document check caught a salary evidence gap on a Skilled Worker file two of us had already read. That is the whole subscription paid for in one afternoon.

Questions firms ask first

Something not here? Ask us directly.

Does using Marcus create a supervision problem?+

No. Marcus produces work product for review, in the same way a paralegal would. A fee earner has to approve every output before it can be sent, and the approval is recorded against the matter.

How does it keep up with Rule changes?+

Requirements and deadline logic are versioned by date, so a matter is always assessed against the Rules in force on its date of application rather than today's.

What happens to client data?+

It stays in the UK, it is never used to train models, and you can delete a matter and its documents at any point. A data processing agreement is available before you upload anything.

Which routes are covered?+

Skilled Worker, Global Talent, student and dependant routes, spouse and partner applications, ILR, naturalisation, and first-tier appeals. Others can be added for Chambers plans.

Do we need to change case management systems?+

No. Most firms start by dragging files in directly. Integrations exist for the common UK systems if you want matters to sync automatically.

Eugene Pavlov, founder of Marcus
Why we built it

Immigration work is unforgiving about detail

A refusal rarely turns on a point of law. It turns on a payslip covering five months instead of six, or a certificate that expired a fortnight before submission. That's a mechanical failure — and mechanical failures are exactly what software should catch, not what a qualified lawyer's time should go on.

I built Marcus with immigration practitioners, not just for them. It's deliberately narrow: it knows one area of law well, checks the details that decide refusals, and always hands the judgement back to a Immigration lawyer.
