DocuPilot
An AI co-pilot for lawyers, consultants, and financial analysts who work with 50–500 page documents and can't trust vanilla LLMs to remember what they read 100 pages ago.
Legal and consulting analysts running multi-document reviews and due diligence
- Upload multi-document matter files (PDFs, contracts, exhibits); the app auto-builds a structured knowledge graph and section-by-section summary backbone
- Question mode that always re-anchors answers to specific pages and clauses, with side-by-side citations and a 'confidence per finding' flag
- Long-running 'deal thread' where you ask follow-ups over days — key facts are re-injected automatically so the model never loses track of counterparties, dates, or figures
- Audit log showing exactly which document sections informed each answer, exportable as a memo
The paper confirms what professionals already feel: long-context LLMs degrade and current attention hacks don't fix it. As law firms and consultancies push AI into M&A and contract review, reliability gaps are now a board-level risk, not a research curiosity.
Legal AI adoption is real and accelerating: ABA 2024 TechReport tracks widespread firm adoption, Thomson Reuters built CoCounsel around long-doc workflows, and Harvey raised $100M (2024, $1.5B) then $150M (2025, $8B) on legal copilot demand.OpenAI-backed legal tech startup Harvey raises $100M ↗Which Legal AI Tools Are Law Firms Actually Using? ↗
Crowded field: Harvey, Spellbook, Thomson Reuters CoCounsel, Kira (Litera), Luminance, Hebbia, Glean all compete for long-doc legal/consulting workflows; the 'attention-degradation' niche is a feature wedge rather than a wide-open category.Spellbook vs. Harvey: Legal AI Comparisons ↗Which Legal AI Tools Are Law Firms Actually Using? ↗

Long-document work is permanent in law, finance, and consulting; attention limits in transformers will persist for the foreseeable future
Buildable but hard: requires combining retrieval/anchoring layer on top of frontier models, domain-specific eval harnesses, and enterprise security; the source paper itself shows current attention interventions don't fix the problem, so the core IP is non-trivial R&D.LLM Document Corruption: 25% Degradation Rate Exposed ↗
