Contract mechanics,
proofread on your Mac.

Section 9 is cited, but there is no Section 9. A term is defined twice. The signature block names a different company than the preamble. OhmsCounsel finds slips like these with fixed rules and opens the exact passage of each one.

Checks document mechanics only. Not legal advice.

Available today

Open a PDF, DOCX, plain-text, or Markdown agreement and choose Verify Agreement from the Review menu (Command-R). OhmsCounsel checks defined terms, definition pointers, section numbering, cross-references, exhibits and schedules, party names, number words, and renewal notice periods, then lets you confirm, reject, annotate, and export the result as Markdown or PDF. The rules read English-language drafting.

AI summaries, clause playbooks, draft comparison, document chat, and the optional cloud key are no longer part of OhmsCounsel, and there is no model to download. Summaries, risk flags, playbook comparison, and clause-level redlines live in a Legal / Contracts vault in Silo Vault, alongside cited answers across your documents.

Why this exists

Drafts break at
the mechanics.

A renumbered clause leaves a reference pointing nowhere. A party's name changes between the first page and the last. Thirty days becomes (60). A tired read can miss slips like these, and they follow patterns a fixed rule can check, on the Mac where the agreement already lives.

No model · no internet

Fixed rules, run on your Mac.

Every check is a fixed rule that runs in a private helper on this Mac, with no AI model to download and no internet request. The same text always gives the same findings.

Available today · inspect

Every finding at its passage.

Selecting a finding opens the source text it came from, with the page when the PDF keeps page breaks. You judge each slip in context instead of trusting a summary of it.

Available today · decide

Your judgment stays yours.

Confirm or reject each finding and save a reviewer note. Your wording stays labeled apart from the automated text, and the imported file is never changed. OhmsCounsel checks mechanics; it is not legal advice.

Current tools.

Available today

Defined terms.

Quoted terms used but never defined, defined twice, defined and never used, or capitalized inconsistently. Parenthetical definitions such as (the “Agreement”) count as definitions.

Definitions
Available today

Definition pointers.

“As defined in Section 4.2” pointers that lead to a section which does not actually define the term.

Pointer check
Available today

Section numbering.

Section numbers that skip, repeat, run out of order, or lack a parent section. Exhibits and schedules keep their own numbering.

Structure
Available today

Cross-references.

References to sections, exhibits, schedules, or annexes that do not exist, and attachments nothing in the agreement refers to.

References & attachments
Available today

Party names.

A party whose name changes between the preamble, the body, and the signature block, including near-miss spellings.

Preamble to signature
Available today

Numbers & notice.

Amounts whose words and digits disagree, such as “thirty (60) days”, and renewal notice periods longer than the renewal term.

Arithmetic
Available today

Confirm, reject, note.

Decide each finding and save a reviewer note in your own words. Notes stay labeled separately from the automated finding.

Human decision
Available today

Reviewed report.

Save findings, decisions, and notes as Markdown or PDF to the folder you choose. The report carries a not-legal-advice notice.

Markdown & PDF
Available today

Sample NDA.

The bundled sample NDA carries one of each defect and opens straight into Verify, so every kind of finding appears before your own agreement.

One of each defect
Available today

Local purge.

Deleting an agreement removes its imported file, extracted text, page map, decisions, and notes after you confirm. A report you saved to your own folder is left alone.

Document-scoped

Pay once. Then keep reviewing.

Questions.

Not to Silo Systems, which runs no server. OhmsCounsel makes no internet requests: import, text extraction, every check, your decisions and notes, and report export all happen on your Mac, in a private helper that listens only on this Mac. There is no account, no analytics, and no telemetry. Earlier versions, including 1.8.1, also offered an optional Bring Your Own Key mode that sent document text, questions and playbook positions directly from your Mac to the provider you configured, plus an optional model download and model-catalog check that carried none of your documents.

A second read for the mechanics.

OhmsCounsel is on the Mac App Store for a one-time $19.99 purchase. It checks document mechanics; it is not legal advice and does not judge whether a contract is fair or complete.
