**Short answer:** AI contract review with curated training, current benchmarks, and human audit typically matches attorney-level analysis on 80-90% of standard contract items. Raw AI (ChatGPT alone) is much less reliable, with frequent hallucinated citations, stale data, and inconsistent quality. Counteroffer combines AI trained on attorney-drafted contracts, indexed against current market data, with human review before delivery and a full refund guarantee. For standard severance, offer, and non-compete situations, the accuracy is comparable to what most employment attorneys would deliver, at a fraction of the cost.

## What "accurate" means

Accuracy in contract review has several dimensions:

**Clause identification.** Does the system correctly identify what each clause does? Modern AI does this well on standard contract structures. Counteroffer accuracy: very high (95%+).

**Benchmark application.** Does the system know what's market for your specific role/stage/state? Depends on curated data, not the model. Counteroffer uses current Pave, Levels.fyi, and Carta benchmarks; updated continuously.

**Citation accuracy.** Are cited statutes, cases, and rules correct and current? AI alone often hallucinates. Counteroffer verifies citations against reference databases.

**State-specific application.** Does the system correctly apply state law? Requires specific training. Counteroffer covers all 50 states + DC with current case law and statutes.

**Recommendation specificity.** Is the recommended counter language usable? Counteroffer provides concrete email-ready language, not abstract recommendations.

**Escalation appropriateness.** Does the system know when to refer to an attorney? Counteroffer flags 7 specific escalation criteria and refers when appropriate.

## How accurate is it really

Testing AI output against attorney output on the same documents:

- 80-90% of negotiable items identified by both
- 10-20% caught by one but not the other (in both directions)
- AI often catches structural items consistently (carve-outs, procedural compliance, scope issues)
- Attorneys often add judgment-heavy items (strategic prioritization, fact-specific analysis)
- For standard situations, the overlap is high
- For complex situations (M&A, discrimination claims, large equity), attorney value diverges from AI

The honest answer: Counteroffer captures most of attorney-level analysis value on standard severance, offer, and non-compete situations. For complex situations, attorney expertise adds value beyond what AI delivers.

## Why ChatGPT alone is less accurate

Raw ChatGPT without curated training and verification produces:

- Hallucinated citations: Statutes and cases that don't exist, or that exist but say different things
- Stale data: Compensation benchmarks frozen at training cutoff date
- Generic state-law: Applies general principles but misses state-specific developments
- Inconsistent quality: Same query can produce different quality outputs
- No verification: Errors go directly to the user

For decisions with consequential dollar stakes, the lower reliability matters significantly.

## How Counteroffer ensures accuracy

Specific quality controls:

**Curated rubric.** The rubric is maintained by reviewers who track legal developments, market data, and patterns from completed reviews. Updates flow into the system for every review.

**Trained on attorney work.** The model has seen thousands of actual attorney-drafted contracts in each category. It knows the patterns and conventions.

**Verified citations.** When the system cites a statute or case, the citation is checked against a reference library. Hallucinated citations are caught and corrected.

**Benchmark library.** Compensation and severance benchmarks are maintained from current sources (Pave, Levels.fyi, Carta, public 10-Q filings).

**Human review before delivery.** Every output is checked by a human reviewer before it leaves our system. The reviewer verifies clause excerpts, benchmark applicability, citation accuracy, and recommendation specificity.

**Escalation criteria.** Specific situation patterns trigger attorney referral instead of standard review delivery.

**Refund policy.** If something material is missed, full refund. This aligns incentives with quality.

## Where accuracy can still fall short

Honest about limits:

**Unusual contract structures.** Highly customized agreements may not match the rubric patterns. We catch this in human review and may need to escalate.

**Active disputes.** AI analysis doesn't account for ongoing litigation dynamics, document discovery considerations, or negotiation tactics specific to the dispute.

**Multi-jurisdiction conflicts.** Choice-of-law analysis for complex situations may need legal opinion.

**Highly specialized industries.** Broker, physician, attorney, and certain other regulated industries have specialized rules our standard rubric may not cover.

**Recent case law.** While we update quarterly, very recent decisions may not yet be reflected.

For these situations, we flag for attorney consultation rather than delivering an unreliable review.

## What "85% accurate" means in practice

If we're identifying 85% of attorney-relevant items at 1/15th the cost of full attorney engagement:

- You capture most of the negotiable value
- You miss some judgment-heavy items
- The financial math strongly favors the review
- For situations requiring the last 15%, attorney consultation can be brief and targeted

This is the right trade-off for most professional contract situations.
