SumizAI and CoreProse side by side: price, licence, platforms and what each one actually does. ## What CoreProse is CoreProse is a French platform generating long-form B2B content using advanced RAG (Retrieval-Augmented Generation) — an approach where the AI model grounds its output in specific, verified sources rather than general internal knowledge. The platform's operating principle is strict: every claim in the generated text must be tied to a verified source — if no source exists, that claim simply doesn't appear in the final output. This approach addresses one of the biggest problems with marketing and expert content generated by general-purpose AI models: a tendency to produce convincing-sounding but unverified facts. For B2B companies publishing expert content — industry reports, white papers, thought-leadership articles — the credibility of every claim directly affects brand reputation, so CoreProse's rigor answers a real market need. The "no source means no claim" approach matters especially in technical and financial content, where one unverified statistic, cited with no reference to a study or report, can be caught by an expert reader and undermine trust in the rest of the material, even if the other ninety percent of the content was fully accurate. A freemium model lets content teams test output quality at a smaller scale before fully rolling the platform out for ongoing company content production. The platform runs as an online service, accessible with no extra software to install, which makes it easier to integrate with a marketing team's existing editorial process. The rigor of tying every claim to a source also means generation tends to be slower than with tools lacking that constraint — CoreProse deliberately trades speed for credibility, which for B2B content aimed at business decision-makers is usually the right tradeoff, given the reputational cost of a single false claim in a company's public report. A content team using CoreProse to produce regular industry reports builds up a large library of texts over time, each grounded in a specific set of verified sources. Without a system for organizing those sources separately from the text itself, it becomes hard later to check exactly which sources a given paragraph was based on, especially when a report needs updating with new data months later. Keeping a standalone ai notes per report solves that problem once and for all. SumizAI complements CoreProse exactly at that point: the list of sources used for a specific piece of text, along with a note on which claims came from which source, can be saved as ai notes in a local Markdown file independent of the CoreProse platform itself. An editor responsible for updating recurring reports ends up with a library of ai notes holding sources for every topic, ready for a quick refresh at the next edit cycle. These tools complement each other: CoreProse handles rigorous content generation grounded exclusively in verified sources, while SumizAI ensures the documentation of those sources survives as these notes available to the whole team, independent of any single generated document's lifecycle. A new content team member joining a project mid-way ends up with ready-made these notes holding the full source history, instead of having to manually reconstruct it from just the final report text. **Key facts** - Price: Freemium - License: Proprietary - Origin: France, EU - Category: AI Writing ## 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 - AlternativeTo's description of CoreProse does not mention an AI model. That is the whole starting point in SumizAI: you have a conversation with a model on your own API key, and the answers worth keeping become notes without you filing them. - CoreProse 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 CoreProse 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. - CoreProse 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. - Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.
