SumizAI vs Article Summarizer

What Article Summarizer is

What Article Summarizer is

Article Summarizer is a UK-based Google Chrome extension and web app that instantly summarizes articles and PDF documents using AI. Instead of reading an entire long piece, a user gets a concise summary of the key points, and can additionally "chat" with the content — asking questions about a specific article and getting answers pulled directly from that document rather than from the model's general knowledge. The tool is free, making it accessible to anyone who regularly has to get through large volumes of reading material.

The browser extension integrates directly with pages a user is already browsing — there's no need to copy text into a separate app or manually upload a file; running the tool on the active browser tab is enough. PDF support means it works just as well with academic papers, industry reports, or legal documents as with typical blog posts or news articles.

The fact that the tool is UK-based and offered entirely for free sets it apart from many competing article summarizers, which hide the most useful features — like chatting with a document — behind a premium plan only available after a trial period ends.

A common use case is quickly checking whether a long article actually contains the information needed at the moment, before committing time to reading it in full — the chat-with-content feature lets someone ask a specific question and get an answer without visually scanning the whole text. A free model with no input limits makes the tool suitable both for a one-off summary of a single article and for systematically processing dozens of sources as part of a larger research project.

Someone using Article Summarizer for research — a journalist preparing a piece based on dozens of sources, or a student gathering material for a paper — quickly generates many summaries, each tied to a different source. Without a system for organizing those summaries, it's easy to lose track of which source said what, especially when research stretches over several days or weeks. Saving summaries as standalone ai notes with a link back to the original article solves that problem.

SumizAI is a great fit for that role: a summary generated by Article Summarizer, together with answers to questions asked and the source link, can be saved as ai notes in a local Markdown file, searchable regardless of how many browser tabs were open during the research. A journalist preparing an in-depth piece ends up with one organized ai notes file gathering conclusions from every source reviewed, ready to use when writing the final piece.

These tools complement each other: Article Summarizer specializes in instantly pulling the essence out of a long text, while SumizAI makes sure that extracted essence doesn't vanish along with a closed browser tab, instead landing in lasting these notes ready for later. A student gathering material for a thesis over many weeks ends up with one growing these notes file instead of dozens of browser bookmarks nobody can remember the reason for a month later, saved in the first place for reasons long forgotten.

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.

Every answer kept this way becomes one of these ai notes, ready to search again months later without hunting back through old chats.

Side by side

Where they differ

• Article Summarizer is a place to have the conversation. SumizAI is not a chatbot — the conversation is the input, not the product. What comes out of it is a .md file with a title, a place in base.md and a duplicate check against the notes already in the vault. If you only want to talk to a model, you do not need SumizAI.
• Article Summarizer is free and SumizAI costs a dollar a month after a seven-day trial that takes no card. A dollar is what it costs to run accounts and licences without reselling the model; if free is the requirement, Article Summarizer wins that row outright.
• AlternativeTo's description of Article Summarizer 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.
• Article Summarizer 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.
