Laurel wins for enterprise firms. Billables AI wins for mid-market. But the real question is whether you're passively capturing time or actively logging it — that determines which tool actually fixes your revenue leak.
Attorneys capture only 60-70% of billable time with manual timekeeping. That's 30-40% of revenue left on the table every day. AI billing tools promise to close that gap through passive time capture, automated narrative generation, and intelligent categorization. Here's which ones deliver and which ones are just dressed-up timers.
#1 Laurel — Best for Enterprise Firms
Why it wins: Laurel runs silently in the background, captures every activity across every application, and generates detailed time entries with matter codes and billing narratives — all without the attorney touching a timer.
What Laurel does: - Passive time capture across all desktop and web applications - Automatic matter assignment using AI that learns your work patterns - Billing narrative generation — descriptions that meet billing guidelines - LEDES/UTBMS compliance — auto-categorizes entries by task and activity codes - Integration with major billing platforms — Aderant, Elite 3E, Clio, others
Pricing: Enterprise only. Estimated $50-100/user/month with firm-wide licensing. No self-serve sign-up — requires a sales conversation and implementation.
The ROI case: At a 200-attorney firm billing $400/hour, recovering just 30 minutes per attorney per day = $1.2 million in additional annual revenue. Laurel's annual cost for that firm (~$120,000-240,000) pays back 5-10x.
Limitations: Enterprise-focused pricing puts it out of reach for solos and small firms. Requires IT involvement for deployment. Some attorneys report privacy concerns about passive monitoring.
Best for: Am Law 200 firms, firms with 50+ attorneys, firms losing significant revenue to under-recording.
#2 Billables AI — Best for Mid-Market Firms
Why it's #2: Billables AI offers Laurel-like passive time capture at a price point accessible to mid-size firms. It's not as sophisticated as Laurel's enterprise features, but it captures the core value — automatic time recording without attorney effort.
What Billables AI does: - Background time tracking across desktop applications - AI-generated time entries with editable narratives - Matter suggestion — learns which activities belong to which matters - Integration with popular practice management and billing tools - Mobile capture for out-of-office work
Pricing: $25-50/user/month with team plans. Free trial available. Self-serve signup — no enterprise sales process.
Where it falls short vs Laurel: - Less accurate matter auto-assignment - Fewer billing platform integrations - Narratives need more editing before submission - No LEDES/UTBMS auto-categorization
Best for: Firms with 5-50 attorneys, budget-conscious practices that want passive capture without enterprise pricing. The value proposition is simple: if it captures even 2-3 extra billable entries per day, it pays for itself immediately.
#3 Clio Time Tracking (with Clio Duo AI) — Best Integrated Solution
Why it's #3: If you're already on Clio for practice management, their time tracking with Duo AI is the path of least resistance. It's not passive capture, but the AI suggestions and narrative generation reduce the friction of active timekeeping.
What Clio's AI time tracking does: - Smart time suggestions — reminds you to log time based on detected activities - AI-generated narratives — draft billing descriptions from brief notes - One-click timers tied to matters - Mobile time tracking with voice-to-entry - Billing analysis — identifies patterns in under-billing
Pricing: Included in Clio Advanced ($99/user/month) and Complete ($129/user/month) plans. Duo AI features require Advanced tier or higher.
The trade-off: Clio's approach is semi-passive — it suggests entries but still requires attorney confirmation and initiation. You're not getting Laurel-level automatic capture. But if you're already paying for Clio, the marginal cost of AI time tracking is $0.
Limitations: Not true passive capture. Requires attorney engagement with timers and suggestions. AI narratives are basic compared to dedicated billing AI. Better as a time tracking enhancement than a revenue recovery solution.
Best for: Firms already on Clio who want incremental improvement in time capture without adding another tool.
#4 TimeSolv — Best for Budget-Conscious Firms
Why it's #4: TimeSolv is a standalone legal billing and time tracking platform with AI features at a competitive price. It doesn't do passive capture, but its AI narrative generation and billing automation save significant admin time.
What TimeSolv does: - AI-powered narrative suggestions from brief time entry notes - Automatic billing compliance checks against client billing guidelines - LEDES billing with automated task/activity coding - Invoice generation with customizable templates - Payment processing through integrated payment links
Pricing: Starts at $24.95/user/month for time tracking. Full billing platform at $49.95/user/month. No AI add-on fees.
Where it shines: TimeSolv is the best value for firms that need a billing platform with AI, not just a time capture tool. If you're currently using Excel or a basic timer app for billing, TimeSolv is a massive upgrade at a reasonable price.
Limitations: No passive time capture. AI features are narrative and compliance focused, not capture focused. Less sophisticated than Laurel or Billables AI for revenue recovery.
Best for: Solo and small firms (1-15 attorneys) that need better billing automation and are currently using manual or outdated billing processes.
Passive Capture vs Active Logging: Which Approach Wins
This is the fundamental decision, and it matters more than which specific tool you choose.
Passive capture (Laurel, Billables AI, Smokeball): - Runs in the background, records everything automatically - Captures time you'd forget to log — the 30-40% revenue leak - Requires trust from attorneys (monitoring concerns) - Higher accuracy for total time but sometimes assigns wrong matters - Best ROI for hourly-billing firms with revenue recovery as the goal
Active logging with AI assistance (Clio, TimeSolv): - Requires attorney to initiate entries, AI helps with narratives - Lower privacy concerns — no background monitoring - Captures less total time but entries are more accurate - Better for firms where attorneys are disciplined about timekeeping - Best for firms that need better billing narratives and compliance, not more captured hours
The honest answer: If your firm's biggest problem is attorneys not recording enough time, you need passive capture (Laurel or Billables AI). If your firm's biggest problem is poor narratives, billing guideline violations, and invoice rejections, you need active logging with AI (Clio Duo or TimeSolv).
Both problems? Laurel or Smokeball for capture, plus billing platform AI for narrative quality. The tools are complementary.
The Bottom Line: Laurel for enterprise passive capture, Billables AI for mid-market, Clio Duo if you're already on Clio — the right tool depends on whether you're fixing time capture or billing quality.
