On-premises OCR & AI for block & estate managers

Find any clause in any lease in seconds.
Even in the handwritten ones.

Lease Lens Pro reads your leases, deeds and ground-rent schedules — scanned, photographed or typewritten — and turns them into a searchable archive you can simply ask. "Who's liable for the roof repairs above flat 12B?" comes back with the answer and the exact clause. It runs entirely on your own hardware, so confidential documents never leave the building.

Why Lease Lens Pro

Answer leaseholder questions without leaving your desk — or your network.

Most OCR and "chat with your documents" tools quietly ship your files to someone else's servers. Lease Lens Pro does the opposite — all the intelligence, none of the exposure.

Ask your leases a question. Get the clause back.

Leases, signed contracts, deeds, ground-rent schedules, freehold archives — once Lease Lens Pro reads them, you can simply ask. Every answer is grounded in a citation back to the exact clause, not a confident guess.

  • "Who repairs the roof — freeholder or leaseholder?" — answered with the clause
  • "What's the service charge apportionment for this unit?"
  • "Is subletting permitted?" — every answer cites its source passage
Can the leaseholder of flat 12B sublet, and is landlord consent required?
Subletting is permitted with the landlord's prior written consent, not to be unreasonably withheld.
SOURCE · lease.pdf, clause 4.3 "…not to underlet the whole without the prior written consent of the Landlord, such consent not to be unreasonably withheld…"

Reads the documents others can't

Faded carbon copies, cramped handwriting, skewed phone photos, mixed scripts, stamps and marginalia. A vision-language model interprets the page like a person would — context and all — rather than matching glyphs.

  • Handwriting, cursive and signatures
  • Non-Latin scripts and multi-language pages
  • Low-contrast scans, photos and PDFs
Faded original
Clean text

One searchable archive for the whole portfolio

Every lease, deed and schedule becomes part of a single private corpus. Search across buildings, compare terms between units, and pull up every lease that mentions a particular covenant — in one query.

  • Search every building at once, not one PDF at a time
  • Compare repair obligations, apportionments and covenants across units
  • Every result links back to the page it came from
Flat 4, Marlborough House
clause 3.9 — "…not to keep any dog, cat or other animal without prior written consent…"
12B Eastcote Road
clause 5.1 — "…no animals or birds shall be kept upon the premises…"

Private by architecture, not by policy

Lease Lens Pro installs on your own hardware and runs fully offline. Files are read in memory and the extracted text stays in a database you own — there's no third-party service to log, retain or train on your documents.

  • Self-hosted — works even on air-gapped networks
  • Zero data retention by design — helps satisfy GDPR data-minimisation
  • No cloud account, no usage quotas, no surprise invoices

How it works

From shoebox of paper to answers — in three steps

01

Drop in your leasehold documents

Drag in scanned leases, photos, PDFs, Word or text files. Lease Lens Pro renders each page locally and queues it for reading.

02

The on-premises model reads them

A local vision-language model extracts clean, structured text — handwriting, faded print and all — without a single byte leaving your network.

03

Search it & ask it anything

Your paperwork becomes a private, searchable corpus you can question in plain English — with citations back to the page.

Built for sensitive leasehold paperwork

Where Lease Lens Pro earns its keep

Anywhere leasehold documents are confidential, physical, or simply hard to read.

Block & estate management

Answer service-charge, ground-rent, repair-obligation and consent questions across every building you manage — without digging through the filing drawer or waiting on the freeholder's solicitor. Each answer comes back with the clause behind it, citation included.

Leaseholder & freeholder enquiries

Turn the daily flood of "am I allowed to sublet?" into a 30-second cited answer instead of a 20-minute dig through the filing drawer.

Archives & historical records

That 1972 deed of variation nobody can find? Ask for it. Decades of paperwork become a private, queryable archive that lives entirely on your hardware.

Questions, answered

The practical stuff

What hardware do I need?
A single machine with a modern GPU — a capable workstation or a server in your rack. We'll confirm exact sizing with you during early access, before you commit to anything.
What does it cost?
A simple licence for your team — no per-page fees and no metered usage, however many documents you process. We'll agree early-access pricing with you directly when we get in touch.
Does anything ever leave our network?
No. Reading, indexing and question-answering all happen on your hardware, and it works with the network cable unplugged. The only thing that ever leaves your building is the interest form on this page.
Is this legal advice?
No — Lease Lens Pro finds and cites what your documents actually say, so you can answer enquiries quickly and check the source yourself. Decisions and advice stay with you and your professional advisers.
Who's behind Lease Lens Pro?
It's built by Jupiter & the Giraffe, a software studio — you'll be talking directly to the people building the product, not a sales team.
