SumizAI and Lucius AI side by side: price, licence, platforms and what each one actually does. ## What Lucius AI is Lucius AI is a compliance-first tender intelligence platform — a forensic auditor for RFPs, tenders, and contracts. Unlike general AI tools that summarize text, Lucius runs clause-level compliance audits on 500+ page procurement documents: it extracts every requirement, flags discrepancies, and builds a full, searchable map of the obligations arising from a given document. A freemium model lets people try core functionality for free, while a full subscription unlocks deeper document analysis and handling more tenders at once. An origin listed as "International" suggests a geographically distributed team serving clients across multiple jurisdictions at once, which makes sense for a tool addressing the public procurement market, where regulations vary significantly between countries but the need for rigorous compliance analysis remains universal. Clause-level precision, rather than just a summary of a document's general meaning, matters fundamentally in the context of public tenders, where missing one small-print formal requirement can disqualify an otherwise carefully prepared bid, regardless of its substantive merit. A legal department at a company regularly responding to dozens of public tenders a year, using Lucius AI to audit compliance for every tender document, gradually builds knowledge of which types of formal requirements most often disqualify competitors' bids and which are easy to overlook on a cursory read. Without systematically documenting those observations, that valuable institutional knowledge gets lost through legal department staff turnover. SumizAI complements Lucius AI exactly at that point: key observations from compliance audits — recurring requirement types, common formal traps, proven strategies for responding to tricky clauses — can be saved as ai notes in a local Markdown file, building institutional memory independent of specific staff turnover. A legal department responding to tenders across multiple countries at once ends up with ai notes per jurisdiction, making it easier to quickly get oriented in local regulatory specifics. These tools complement each other: Lucius AI runs a rigorous clause-level compliance audit for a specific tender document, while SumizAI ensures the conclusions from many such audits survive as ai notes building the company's long-term institutional knowledge of the public procurement market. A company bidding on tenders across a dozen or more countries at once especially benefits from keeping a separate these notes per jurisdiction, since the specifics of formal requirements, official documentation language, and typical procedural traps can differ dramatically between markets, and mixing those observations in one place leads to costly mistakes on the next tender in a different country. These notes saved right after each audit run by Lucius AI, capturing both the discrepancies found and the resolution the contracting authority accepted, over time become a kind of internal precedent base for the legal department, far cheaper to maintain than a formal legal knowledge base and easier to search than an archive of old tender bids in PDF format. A new lawyer joining the team responsible for foreign tenders, given access to these notes gathered by their predecessors, needs far less time to confidently handle the next complex request for proposal on their own. **Key facts** - Price: Freemium - License: Proprietary - Origin: International ## What SumizAI is A note-taking application built around a conversation with an AI model. You ask a question, the answer streams back, and the answers worth keeping become Markdown notes — filed into a vault that is a folder on your own disk. A vault is a directory holding `base.md`, a generated table of contents up to six levels deep, and a `notes/` folder with one `.md` file per note. Before a note is written it is checked against the ones already there, so the fourth note about the same idea gets merged instead of added. Links between notes are ordinary Markdown links to files that exist. The model is never ours: you bring your own API key to one of seven providers — Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — and pay that provider directly. A question sends the table of contents plus at most five relevant notes within a 24,000-character budget, and the app shows you which five it used. ## Where they differ - Both mention AI. The difference is whose key it runs on: SumizAI never resells inference — you connect one of seven providers (Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server) with your own API key and pay that provider directly. Check what Lucius AI does with the model bill before comparing prices. - Lucius AI is freemium: there is a free tier and a paid one, and the line between them is the thing to read before committing. SumizAI has one plan at a dollar a month, so there is no feature held back for a higher tier — and an unpaid account still opens and exports every vault it already has. - AlternativeTo's description of Lucius AI does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard `.md` files to a folder you picked, and an unpaid account can still export all of them. - Lucius AI runs in the browser. SumizAI is a desktop and mobile application, and on the desktop the vault is a folder on your own disk rather than a document in someone's cloud.
