Recovery of past CAM overcharges depends on your specific lease terms, including any audit rights deadlines or ‘binding and conclusive’ provisions, and on applicable state law.

State statute of limitations periods apply to written contracts and range from 3 to 10 years. Your actual lookback window may be shorter based on your lease.

CAMAudit vs Google Gemini

Last updated: April 2026

Google's AI assistant, strong at document analysis but not forensic CAM auditing. See how CAMAudit stacks up for commercial CAM reconciliation auditing.

By Angel Campa, Founder

TL;DR

  • +CAMAudit: $79 flat fee, results in under 15 minutes, 14 forensic detection rules.
  • -Google Gemini: Free to $79-200/mo subscription, minutes (manual prompt iteration), general text analysis and document summarization, no cam forensics.
  • iGoogle Gemini uses floating-point approximations. CAMAudit uses Python Decimal arithmetic: every overcharge amount is exact to the penny with an auditable math proof. CAM cap calculations require tracking running balances across multiple years; Google Gemini has no persistent state between sessions. And when two detection rules flag the same line item, CAMAudit's reconciliation engine prevents double-counting. Google Gemini has no concept of inter-rule conflicts.

Bottom line

CAMAudit wins for CAM auditing

CAMAudit is the better fit for any tenant who needs accurate, defensible overcharge numbers. Google Gemini can summarize lease language, but no general-purpose AI tool can replace a forensic audit engine with deterministic math, multi-year state tracking, and double-counting reconciliation.

Not applicable: no structured findings or overcharge quantification

Choose CAMAudit if

  • ✓You need to find CAM overcharges, not just organize lease data.
  • ✓You want quantified findings and the best recovery economics from a flat-fee audit.

Choose Google Gemini if

  • •You only need a general summary of your lease language or want to understand CAM terminology before running a real audit.
  • •You are doing initial research and not yet ready to review a formal findings report.

Overcharge detection

Google Gemini uses floating-point approximations. CAMAudit uses Python Decimal arithmetic: every overcharge amount is exact to the penny with an auditable math proof. CAM cap calculations require tracking running balances across multiple years; Google Gemini has no persistent state between sessions. And when two detection rules flag the same line item, CAMAudit's reconciliation engine prevents double-counting. Google Gemini has no concept of inter-rule conflicts.

ROI and fee drag

Google Gemini is free or low-cost, but it produces nothing a landlord will negotiate against: no structured findings report findings report

Implementation burden

Google Gemini requires manually pasting text, writing the right prompts, verifying every calculation, and formatting your own dispute letter. CAMAudit handles OCR, extraction, 14-rule detection, and dispute letter generation in one upload, in under 15 minutes.

Why tenants choose CAMAudit

  • ✓Deterministic Decimal arithmetic: every dollar amount is exact to the penny with an auditable math proof
  • ✓14 hard-coded detection rules that run the same way every time
  • ✓Multi-year state tracking for cumulative and compounding CAM cap calculations
  • ✓Dispute letter draft with 50-state legal citations, not AI-generated statutory summaries
  • ✓Results in under 15 minutes with OCR and dispute letter included from $79

Google Gemini strengths

  • •Integrates with Google Workspace (Docs, Drive, Sheets)
  • •Can process uploaded PDFs in paid tier
  • •Strong at long-document summarization
  • •Free tier available

Google Gemini limitations

  • •Floating-point math cannot produce penny-accurate financial calculations
  • •No persistent state. Cannot track cumulative CAM cap balances across multiple years
  • •No double-counting reconciliation. Will count the same overcharge under multiple categories
  • •No structured extraction schema for CAM-specific fields. Results are not reproducible
  • •No 50-state legal citation database for dispute letters
  • •No confidence scoring or sanity gates on generated findings

Google Gemini key features

  • •Document summarization and Q&A
  • •Google Workspace integration
  • •Ad-hoc math on pasted data
  • •Long-context document analysis

Notable absences in Google Gemini

  • ✗No purpose-built CAM overcharge detection rules
  • ✗No deterministic math engine

  • ✗No dispute letter with verified state-specific legal citations
  • ✗No double-counting reconciliation
