SumizAI and Clearbrief side by side: price, licence, platforms and what each one actually does. ## What Clearbrief is Clearbrief is an AI tool that lives directly inside Microsoft Word, purpose-built for litigators drafting briefs, pleadings, and motions. Its core feature is real-time fact-checking of legal writing: every assertion in a brief gets a hyperlink pointing straight to the source-document passage that supports it, and a LexisNexis integration catches AI-hallucinated case citations before they ever reach a judge. A lawyer using Clearbrief can scan an opposing counsel's brief for factual weaknesses, uncover hearsay, or spot other inadmissible evidence. An AI scoring system rates every sentence on how well it's supported by the cited evidence, and additional tools — a Table Builder, timelines, one-click automated table-of-authorities generation, and a real-time cross-examination prep mode — speed up work that traditionally consumed hours of paralegal time. For firms billing by the hour, reducing the hours spent manually checking citations translates directly into margin on a matter, and for the client it means a lower bill for the same quality of finished brief, with no compromise on the reliability of any cited source, which matters especially in cases where one misquoted ruling can undermine an entire brief's credibility in a judge's eyes. Clearbrief can also automatically determine which pages and documents have been cited in a brief and instantly generate a ready-to-file PDF of exhibits. The tool has earned industry recognition, including 2025 Innovator of the Year at Legalweek and a 2025 award for best legal compliance solution. Embedding the tool directly inside Word, rather than in a separate web app, matters for firms whose entire brief-drafting process has relied for decades on that specific text editor and its court-compliant formatting. Working on a lengthy brief in Clearbrief produces plenty of small but crucial findings: exactly which passage of testimony backs a given argument, which of opposing counsel's claims turned out to lack evidentiary support, which version of the table of authorities was final. Those findings live inside a specific Word document and are easy to lose track of when moving on to the next case. Keeping standalone ai notes per case preserves those findings independent of any single document's lifecycle. SumizAI complements Clearbrief exactly at that point: key fact-checking conclusions — a confirmed fact along with its source-document reference, a weakness spotted in an opposing brief, the decision behind a final argument's wording — can be saved as ai notes in a local Markdown file, searchable independent of any specific Word document version. A legal team juggling several cases at once ends up with one consistent ai notes file per case, easy to hand off to a new team member joining mid-litigation. These tools complement each other: Clearbrief handles rigorous fact verification inside the document itself, while SumizAI ensures the conclusions from that verification survive beyond a single Word file, gathered into a lasting these notes ready to use at every later stage of the case. A partner overseeing several matters at once can review these notes from each of them without opening the specific Word document, speeding up weekly status reviews across active litigation and making client reporting easier without digging through a document's version history. **Key facts** - Price: Paid - License: Proprietary ## 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 Clearbrief does with the model bill before comparing prices. - Clearbrief is paid software. Compare the two numbers directly: SumizAI is one dollar a month, one plan, and your AI provider bills you separately for the model you chose. - AlternativeTo's description of Clearbrief 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. - AlternativeTo lists no mobile version of Clearbrief. SumizAI runs on macOS, Windows, iOS and Android.
