The incumbent
What Prophia does, in its own words
Prophia describes itself as an AI-powered lease abstraction and lease management platform for commercial real estate owners and operators, serving investment sales, leasing, asset management, and property management teams. Its published workflow pairs AI extraction with review by CRE experts: documents go in, AI abstracts them, and a quality-check step by human specialists follows before final review. Its site reports 720 million square feet and more than 230,000 documents on the platform.
The published feature set is genuinely strong for that market: lease data linked to its source documents, self-updating stacking plans, encumbrance and tenant-rights tracking, rent roll tooling, and portfolio dashboards. Prophia's pricing page lists 215 extracted fields and reports 99% accuracy on its human-reviewed Essentials tier, with unlimited users and per-tenant annual subscription pricing available on request. All of the above is per Prophia's own website as of August 2026.
If your portfolio is office, retail, or mixed-use commercial real estate, and you want a managed service with expert review built in, Prophia belongs on your shortlist. What follows is not an argument against that; it is a different set of trade-offs.
The alternative
Where MYX Analyzer differs
The differences are structural: a different kind of portfolio, and a different verification model.
Built for infrastructure documents
MYX Analyzer is specialized for telecom tower and infrastructure portfolios: ground leases, tenant leases, amendments, and the technical files that arrive in the same folders. It has processed approximately 250,000 documents in a single engagement, as reported in Inside Towers. The cell tower lease abstraction page covers this in depth.
Verification stays in-house
Instead of a vendor review service, every extracted value carries a HIGH, MEDIUM, or LOW confidence rating and a document reference to the page and section it came from. Measured extraction quality is 94.7 % on internal evaluation sets; your team verifies the values that need it and can defend every number to an auditor.
A schema you define
MYX Analyzer extracts 500+ data fields, and every column is a plain-language prompt you write. A field specific to your portfolio is a column you add and rerun, not a change request. The same schema runs across 40+ languages, which matters when an infrastructure portfolio crosses borders.
Self-serve, with published pricing
You can try the free demo without a sales call, then run your own documents in a 30-day free trial. Plans are published on the pricing page: Pro at €99/month with 5,000 credits, Business at €999/month with 50,000, overage at €0.05 per credit. Batch runs show an upfront cost estimate before submission.
Scale is the fifth difference, and it is operational: process hundreds of documents overnight with enterprise batch processing, review results in a spreadsheet-style grid, and rerun a single cell, a row, or a column when a prompt needs tightening. Results export to Excel with custom templates, which is how extracted data reaches rent rolls, asset registers, and Salesforce-based site-management systems.

The Prophia column states only what its public materials say; where its materials do not state something, the cell says so rather than guessing.

Prophia column compiled from prophia.com (homepage and pricing page), August 2026. Accuracy figures are not directly comparable: Prophia's published 99% includes expert human review; MYX Analyzer's 94.7 % is measured on internal evaluation sets before customer review.
Decision guide
Decide by portfolio, not by feature list
Office, retail, or mixed-use REIT
Your unit of management is the tenant: stacking plans, encumbrances, CAM language, renewal pipelines, investor reporting. Prophia's published product is aimed squarely at this work, with expert review built into the service. Evaluate it and its CRE-focused peers first; generic tooling underserves this workflow.
Tower, energy, or infrastructure portfolio
Your unit of management is the site: ground lease versus tenant lease, escalation clauses tied to national indices, drawings and regulatory documents mixed into the same folders, portfolios that cross languages, and M&A moments when thousands of documents need reading at once. This is what MYX Analyzer is built for — see due diligence and rent calculation for the two workflows that usually decide the purchase.
If you hold both kinds of assets, run both evaluations. Abstraction quality is a testable claim: the same 20 documents, the same field list, two tools, one afternoon of checking values against sources. The lease abstraction page shows what the MYX Analyzer side of that test looks like.
Evaluation
A vendor-neutral evaluation checklist
Whichever way you lean, the same seven checks keep the decision honest:
- Test on your worst documents, not your best. Pick 20 real files: aged scans, a handwritten amendment, at least one non-English lease if your portfolio has them.
- Define the fields your systems actually consume. Start from the columns in your rent roll and asset register, and include the escalation clause verbatim, not just the percentage. The free escalation calculator shows why the clause text matters.
- Trace every value to its source. For each extracted field, ask: can a reviewer jump to the exact page and clause? A number nobody can trace is a number nobody can defend.
- Time the correction loop. Find a wrong value, fix the cause, and re-extract. In MYX Analyzer that is editing a prompt and rerunning the cell; whatever the tool, measure it in minutes, not tickets.
- Get scale pricing in writing. Ask what a 10,000-document pass costs before you commit, not after. Published plans and an upfront cost estimate on every batch run make that arithmetic checkable.
- Check the export path. The deliverable is usually a workbook. Confirm results land in the Excel format your team already maintains rather than starting a reformatting project.
- Ask the security questions early. Certifications (MYX is ISO 27001 certified), encryption, and a contractual commitment that customer documents are never used to train AI models. Details are on the security page.
On migration: you do not migrate old abstracts, you re-run the source documents and use the old abstract as a check set. Where the two disagree, the document reference settles it.
FAQ
Is MYX Analyzer a direct Prophia alternative?
The two overlap on AI lease abstraction and differ in focus. Prophia's published materials describe a lease management platform for commercial real estate owners and operators, with expert review as part of the service. MYX Analyzer is built around telecom tower and infrastructure portfolios: a self-serve grid where your team defines the fields, and every value carries a confidence rating and a reference to the source page. Teams with office or retail portfolios and per-tenant lease management needs should evaluate Prophia seriously; teams reading tower, energy, and infrastructure documents at scale are the portfolios MYX Analyzer is built for.
How do the accuracy claims compare?
They measure different things, so read both carefully rather than comparing the numbers directly. Prophia reports 99% accuracy for its human-reviewed tier, per its published materials as of August 2026 — a figure for AI extraction plus expert review. MYX Analyzer's measured extraction quality is 94.7 % on internal evaluation sets, before your own review; the product then gives each value a HIGH, MEDIUM, or LOW confidence rating and a document reference so your team verifies in-house. The reliable comparison is a trial on 20 of your own documents.
Do I have to migrate existing lease abstracts to switch tools?
No. The practical path is to re-extract from the source documents rather than import old abstracts. Upload the leases, define your fields as columns, run the extraction, and use your existing abstract as the check set: where the two disagree, the document reference on each MYX Analyzer value takes you to the clause that settles it. Your documents and your field schema are the durable assets, not the old spreadsheet.
Run the comparison on your own leases
The fastest way to decide is evidence: upload 20 of your documents, define the fields your systems need, and check every extracted value against its cited source.
