How Lease Clause Plain English Summarizer works

Press Load model once: your browser downloads Gemma 4 E2B instruction-tuned (web build) (2.0 GB) from this site and keeps it in its cache. Then add your text and press Summarize locally. The model runs on this device using your graphics card, so nothing you enter is sent to a server. Until the model is loaded, or if your device cannot run it, the tool falls back to a simple keyword check and labels the result as the fallback.

Gemma 4 E2B instruction-tuned (web build) is a small open language model from Google. The tool sends it the instruction below plus your text, asks for a JSON answer with fixed fields, and shows each field as a card. It runs at temperature 0, so the same input gives the same answer on the same device, though different graphics cards can word it slightly differently.

Inputs longer than 6,000 characters are cut to that length before they reach the model, and the result says so. The model only sees what you paste: it does not look anything up.

The instruction the model gets

You explain one lease clause in plain English for a tenant who is not a lawyer. Be concrete about who pays or who must act. Read exceptions carefully: words like 'except', 'unless' and 'provided that' carve cases out of the main rule, so say plainly who is responsible in the excepted case. Do not give legal advice and do not say whether the clause is enforceable.

What it returns

  • Plain English: One or two short sentences restating what the clause makes the tenant or landlord do.
  • Clause family: One of: indemnity, holdover, operating expenses, escalation, assignment or sublet, repair and maintenance, personal guaranty, default and cure, security deposit, use, insurance, other.
  • Who carries the risk: Tenant, landlord or shared, with a few words on why.
  • What it leaves unsaid: Gaps a tenant should notice: missing caps, notice periods, carve-outs or time limits.
  • Questions to ask: Two or three questions the tenant could take back to the landlord or a lawyer.

Worked example

The model's output for the built-in sample, recorded on a desktop browser. Your run may word things slightly differently.

Lease clause: Tenant shall indemnify landlord for damages arising from use of common areas except where caused by landlord gross negligence.
Plain English
If you cause damage to the common areas, you must pay to fix it for the landlord. However, this protection does not apply if the damage was caused by the landlord's serious carelessness.
Clause family
indemnity
Who carries the risk
Tenant
What it leaves unsaid
What level of damage is covered? What is the process for the tenant to claim indemnity? What is the definition of 'gross negligence'?
Questions to ask
What specific damages are covered by this indemnity? How should I notify the landlord if I need to claim indemnity? Can you provide an example of what constitutes landlord gross negligence?

Limitations

  • Small language models make mistakes: they can miss an item, merge two, or state something more confidently than the text supports. Check the result against your input before you rely on it.
  • It needs WebGPU and about 8 GB of memory, so it is offered on desktops and laptops, not on phones and tablets. Devices that cannot run it get the keyword fallback, clearly labelled.
  • Results describe the input you gave, not the real-world situation behind it. Review them yourself before acting.
  • This is not financial, tax or legal advice. Confirm anything important against your own records and with a qualified professional.

Good uses

  • Decode one clause your landlord or broker glossed over
  • Compare the same clause across two competing lease offers
  • Build a punch list of questions before paying for legal review
  • Spot uncapped, open-ended, or one-directional obligations
  • Re-read a renewal you signed years ago and forgot
  • Keep an unsigned draft in your browser instead of uploading it

Frequently Asked Questions

Common questions about the Lease Clause Plain English Summarizer

No. The model files download from this site once, and then everything runs in your browser tab. The text you enter is never sent to a server, and closing the tab discards it.
