Feature-by-feature
Luminix excels at multi-agent research: it decomposes questions into sub-threads, uses parallel agents with different models (Gemini, Grok, Claude Opus) for grounding, research, and synthesis. It includes a cynic agent for counterpoints, supports document upload, and lets you customize synthesis prompts. Outputs are PDF or Markdown reports—ideal for strategists and investors. Alexi is purpose-built for law firms: it generates legal research memos, provides a hearing-readiness checklist, compares contracts, drafts documents, and automates workflows. It learns from a firm's prior work via playbooks and templates. Alexi also integrates deeply with legal tools like LexisNexis, Westlaw, Clio, and iManage, while Luminix lists no integrations. Both offer advanced analysis but in completely different domains: general business intelligence vs. specialized legal practice.
Pricing compared
Luminix uses a freemium model, making it accessible for occasional use and testing; pricing beyond free tier is not detailed but suggests suitability for moderate-volume users. Alexi requires contacting sales, indicating enterprise-level pricing typical for secure, private-deployment legal software. This aligns with its SOC 2 certification and single-tenant deployment. For budget-conscious individual researchers, Luminix wins on price. For law firms with compliance needs and budget, Alexi's tailored plan is expected.
