Runtime inside the firm's network. Any LLM the firm chooses. ABA Model Rule 1.6 by deployment. ## Why Firms Look for a Co:Counsel Alternative Three drivers — overlapping with the Harvey-alternative discussion but with TR-specific factors: **1. Per-lawyer pricing at $200–500/month.** A 200-lawyer firm pays **$40–100K/month** — close to $1.2M/year — for a tool whose usage concentrates on a fraction of the lawyers. The bill scales with headcount; the value doesn't. **2. Westlaw-stack lock-in compounds the per-lawyer cost.** Co:Counsel ships as part of (or alongside) Westlaw subscriptions. Firms looking to renegotiate the Westlaw bill find the AI component bundled in ways that make the AI cost hard to isolate. **3. Privileged documents in TR's cloud creates the ABA Rule 1.6 question.** Same architecture problem as Harvey: privileged work product traverses the vendor cloud at request time. State-bar opinions are converging on the view that managed AI vendors for privileged work product require a level of attorney supervision that's hard to satisfy at scale. For the broader policy framework: **[AI Policies for Law Firms: A Practical 2026 Guide](/blog/ai-policies-for-law-firms)**. ## What ibl.ai Does Differently **Self-hosted runtime.** The agent runtime (OpenClaw / NemoClaw) executes inside the firm's network. Privileged documents never leave the firm's perimeter. **Model-agnostic.** Run Claude (any tier), GPT-5, Gemini, Llama 4, DeepSeek-R1, Qwen 3 — set the routing policy per practice group. M&A wants Opus for complex covenant negotiations; litigation wants long-context Gemini for discovery review; bulk diligence wants self-hosted Llama 4 for cost reasons. **No per-lawyer pricing.** Usage-based or flat-rate platform license + GPU. A 200-lawyer firm running 30K contract reviews/month pays ~$5–8K/month all-in. **Open source.** OpenClaw runtime is MIT-licensed. Perpetual platform license. The firm can audit, fork, customize. **Independent of Westlaw.** ibl.ai is a horizontal platform, not a research-database adjacency. The firm's existing Westlaw / Lexis / Bloomberg subscriptions are independent purchasing decisions. ## What ibl.ai Replaces from Co:Counsel's Surface Same workloads Co:Counsel handles, on the firm's infrastructure: - **Contract review** — first-pass redlines, clause classification, risk flags - **Due diligence** — bulk document review for deal rooms - **Legal research** — internal-knowledge-base Q&A, doctrinal analysis (your firm's brief bank + Westlaw-style citation as needed) - **Brief-writing assistance** — drafting outlines, precedent discovery, structural review - **Deposition preparation** — exhibit summarization, witness-specific question generation, timeline building - **Litigation eDiscovery** — privilege-log review, relevance classification For the per-contract token math + Harvey / Co:Counsel / Spellbook / Ironclad AI / LinkSquares vendor comparison: **[What AI Contract Review Actually Costs in 2026](/blog/what-ai-contract-review-actually-costs-2026)**. ## The Cost Math A 200-lawyer AmLaw firm running ~30,000 first-pass contract reviews/month + general legal AI work: | Approach | Monthly cost | Privilege posture | |---|---:|---| | **Co:Counsel** ($300/lawyer × 200) | **$60,000** | Vendor cloud (DPA) | | **Harvey AI** ($400/lawyer × 200) | **$80,000** | Vendor cloud (DPA) | | **Spellbook / Ironclad AI / LinkSquares** ($2/contract × 30K) | **~$60,000** | Vendor cloud (DPA) | | Direct Claude Sonnet API (token-priced) | ~$630 | Anthropic cloud (DPA) | | **ibl.ai self-hosted (Llama 4 / DeepSeek-R1)** | **~$5,000–8,000** | **Inside the firm's network** | Co:Counsel is ~10× more expensive than ibl.ai self-hosted at AmLaw scale, with privileged documents in TR's cloud rather than the firm's network. For the segment cost math: **[AI Cost Math for Law Firms: Per-Seat vs Usage-Based in 2026](/blog/ai-cost-math-for-law-firms-per-seat-vs-usage)**. ## ABA Rule 1.6 Posture Differences | | Co:Counsel (managed) | ibl.ai self-hosted | |---|---|---| | Privileged-document location | TR cloud | **Inside the firm's network** | | DPA refresh | Annually + on sub-processor changes | Runtime is part of firm's existing posture | | Discovery / conflicts production | Through TR | Firm produces from own systems | | Model swap | TR approval cycle | Config change inside firm | | Practice-group-specific model routing | Limited | Full control | | Air-gapped option for sensitive matters | Rarely | Fully supported | ## Run the Numbers - **[Harvey AI Alternative](/blog/harvey-ai-alternative)** — sister-vendor displacement (same core argument) - **[On-Premise Legal AI Platform](/blog/on-premise-legal-ai-platform)** — on-premise architecture deep-dive - **[AI Cost Math for Law Firms: Per-Seat vs Usage-Based in 2026](/blog/ai-cost-math-for-law-firms-per-seat-vs-usage)** — segment cost math - **[What AI Contract Review Actually Costs in 2026](/blog/what-ai-contract-review-actually-costs-2026)** — per-contract math + multi-vendor comparison - **[AI Policies for Law Firms: A Practical 2026 Guide](/blog/ai-policies-for-law-firms)** — policy framework - **[Self-Hosted AI vs ChatGPT Enterprise for Legal](/resources/comparisons/self-hosted-ai-vs-chatgpt-enterprise-for-legal)** — deployment comparison ## Why Family-Owned and New York Matters Here A law firm's AI vendor relationship for workloads as central as contract review + legal research is a multi-year commitment touching privileged client work product. ibl.ai is **family-owned and operated from New York, NY** — a long-term partner with a perpetual platform license and no investor exit pressure. The runtime is open source. Privileged work product stays inside the firm's network. The math works at a 5-lawyer boutique or a 2,000-lawyer global firm. The Co:Counsel alternative isn't a different research-database adjacency. It's the firm owning the legal AI platform.
