Auto Review, Accelerated: Tag Tuner Transforms GenAI Document Review

First-pass document review has traditionally been massively time-intensive, with a human contract reviewer reviewing, (per Gartner) on average, 50-60 documents per hour – or 1,660 hours for a 100k doc review. In 2024, DISCO Auto Review turned the tide – delivering first-pass reviews at unprecedented speeds with accuracy metrics that score 10%–20% higher than standard benchmarks for traditional human review.

Now, it’s gotten even better.

When GenAI doc review debuted, building and perfecting the right prompts meant a week or two of manual trial-and-error. If your team faced tight production deadlines, that calibration window could make you think twice about using AI-powered review.

Arriving as a fully integrated capability in August 2026, Tag Tuner for Auto Review changes everything. Our new capability simplifies the process, introducing a guided workflow that makes iterating prompts easier than ever – empowering you to confidently perform your own AI-led reviews.

Shifting From Prompt Engineering to Simple Feedback

Manual prompt engineering used to feel like a specialized chore. Legal teams and highly trained specialists frequently spent days adjusting language in tag descriptions just to fix minor coding disagreements.

Tag Tuner takes down the difficulty and makes the process accessible to everyone, acting as your built-in AI prompt engineer. Instead of requiring you to rewrite complex instructions for tags from scratch, Tag Tuner allows you to review conflict documents in simple batches and provide plain-English feedback. The platform then analyzes your feedback and automatically rewrites the tag definitions for you.

The Outcome: You get optimal review instructions, without needing a degree in data science.

How Auto Review with Tag Tuner Works: Calibration in Four Steps

The underlying setup process replaces manual engineering loops with a fast, circular workflow:

• 1. Run a statistical sample: You start by running Auto Review on a sample data set that your team has already coded manually.
• 2. Identify low performing tags: Tag Tuner batches by tag any conflict documents where the AI disagreed with the human reviewer, and provides precision, recall, and F-1 metrics so you can choose which tags to tune. 
• 3. Provide quick feedback: You review the conflicts and type in a minimum of 5 brief explanations clarifying why the human application is correct.
• 4. Tag-tune your rules: Tag Tuner takes those explanations, automatically re-engineers your tag descriptions, and tests the updated rules against your documents.

Direct Advantages Across Your Legal Teams

By minimizing the manual labor behind AI setup, Tag Tuner delivers immediate operational advantages tailored directly to your practice group.

For Law Firms: Keep Control and Revenue In-House

• Take back control — without burnout: Auto Review provides the results, oversight, and control of DIY review, without the burnout of having associates review every single document.
• Deliver better value for your clients: Free up your brightest minds to focus on matter strategy, counseling clients, and complex legal challenges — and show your clients you’re using the best tools to deliver the best results.
• Keep the review and the revenue in-house: The ease and speed of Auto Review allows firms to keep more reviews in-house, creating a profit center instead of routing revenue to a vendor.

For Corporate Legal: Reduce Costs and Increase Control

• Move at the speed of business: Internal investigations, regulatory inquiries, and data breach response deadlines don't wait. With Tag Tuner’s ability to auto-update prompts based on reviewer feedback, your team can use GenAI to review themselves — no vendor bottlenecks, critical when the clock is running.
• Maximize every dollar of outside spend: Auto Review delivers ~90% precision and recall at tens of thousands of docs an hour. With Tag Tuner simplifying the process and removing the technical barrier, more review work that used to get contracted out can move in-house — reducing legal spend on matters that don't require outside expertise.
• Build a defensible, consistent playbook: Auto-updated protocols standardize how tagging decisions are made across matters and reviewers, giving legal ops and the GC’s team a more consistent, explainable methodology to stand behind — whether the review runs today or six months from now..

Setting Up for Success: Key Guardrails

To maximize your results with Tag Tuner, keep these foundational design rules in mind:

• Optimized for issue tagging: Interactive loop optimization is built strictly for responsiveness and issue tags. Privilege determinations or PII are not handled by the feature and should remain routed to specialized review teams.
• Dependent on text data: The AI requires text to learn. Images, CAD files, and media files must be segregated for human quality control.
• Operational flexibility: While Tag Tuner makes independent self-service a realistic option, it doesn't replace professional services. For managed reviews, we remain with you in every case. Learn about our Review team.
