SumizAI vs Ai Chat everywhere

What Ai Chat everywhere is

What Ai Chat everywhere is

Ai Chat everywhere is a free, open-source Firefox extension that makes an AI assistant accessible on every website, without needing to switch to a separate tab or page. The extension supports several providers at once — OpenAI's ChatGPT, Google Bard, You.com Chat, Perplexity AI, Bing image generation and Suno music generation, as well as Copilot — giving users a choice of model without leaving the page they're browsing.

Key features

Availability on every website means an AI assistant is always within reach — while reading an article, browsing documentation, or working in another web app, a user can bring up the extension without interrupting their current work by switching tabs. Support for multiple providers at once — text, image, and music — makes the extension a versatile access point for different types of generative AI, instead of being limited to one model. Open source code lets the community verify exactly how the extension communicates with each provider and submit fixes. Free access with no charge for the extension itself removes the barrier to entry — costs, if any, come only from paid plans of individual AI providers the user chooses to use.

Who it's for

Ai Chat everywhere appeals to Firefox users who want quick access to AI while browsing the web, without the ritual of opening a new tab and navigating to a specific provider's site. People using several different AI models interchangeably, depending on the task, appreciate being able to switch between providers without leaving the extension. Developers and open source enthusiasts, who value transparency in the tools they use daily, find in the open code an extra reason for trust.

Use cases

In practice, Ai Chat everywhere works well when reading a long technical article and hitting an unclear passage, wanting to quickly ask an assistant for clarification without leaving the article's page. Someone comparing different models' answers to the same question can switch between ChatGPT, Bard, or Perplexity directly from the extension, saving time compared to opening separate tabs. A content creator can generate an image via Bing Image or music via Suno directly from the extension while working on a project in another web app.

Pricing and business model

The Ai Chat everywhere extension itself is completely free and open source. Actual costs, if any, come from the terms of the individual AI providers the extension gives access to — some models offer free tiers with limits, others require their own subscription independent of the extension itself.

Limitations and what to watch for

The extension works only in the Firefox browser, so Chrome, Safari, or Edge users have no access to it without switching browsers. Because the extension is an intermediary to many external services, its functionality depends on the availability and API terms of each provider — a policy change on one provider's side can affect how that specific integration works within the extension.

AI notes from conversations in the extension

Ai Chat everywhere has no built-in mechanism for permanently saving conversations as organized notes — it's an extension that makes access to AI conversation easier, not a notebook. A user wanting to keep a valuable answer as an ai notes entry has to copy it manually into a separate tool, which is easy to overlook when using the extension frequently while browsing many pages.

The attention economics of everyday browsing

Every browser tab switch, even briefly, costs more than just seconds — productivity research shows that returning to full focus after an interruption takes real time, even when the interruption itself was short. Ai Chat everywhere addresses that directly, removing the need to leave the page you're currently on just to ask an assistant something related to the material you're reading.

One install, many AI engines

Instead of installing separate extensions for each AI provider — one for ChatGPT, another for Perplexity, a third for image generation — Ai Chat everywhere consolidates access to several engines into one install. That approach reduces clutter in the browser toolbar and simplifies the decision of which tool to use at a given moment, since all of them are available from the same place.

What's worth checking before choosing

Before relying on Ai Chat everywhere as your main way of accessing AI, check exactly which providers are currently supported and whether you need your own accounts or API keys for the individual services the extension gives access to.

Openness as a survival guarantee

Small, free browser extensions are sometimes abandoned by their creators once they run out of time or motivation to keep developing them. Ai Chat everywhere's open source code gives the community the option to take over development if the original author stops updating it — something a closed, commercial extension dependent solely on one company's decisions doesn't offer. AI notes manually saved from conversations conducted through this extension remain yours regardless of what happens to the extension itself, as long as you keep them in an open file format rather than a closed database belonging to another app.

Bottom line

Ai Chat everywhere is a convenient, free Firefox extension giving quick access to multiple AI providers from any website. Anyone who wants valuable answers from such conversations to automatically become ai notes saved as files should pair the extension with a separate tool built for that purpose.

The ritual of a few clicks

Instead of opening a new tab, typing an address, waiting for it to load, and logging into a service, an extension user clicks one button that's always visible on the toolbar. That difference — a few seconds instead of a dozen, one step instead of five — adds up over a day of heavy web browsing into a genuinely noticeable savings of time and attention, especially for people checking something with AI dozens of times a day. It's worth building a simple habit: if an assistant's answer turns out to be genuinely valuable, copy it right away as ai notes before moving to the next page and forgetting about it. That small habit costs seconds but saves the frustration of trying to remember which of dozens of visited pages a given answer came from — a small price for peace of mind when juggling dozens of tabs a day.

Comparison with SumizAI

Ai Chat everywhere and SumizAI solve different problems in everyday AI-assisted work. Ai Chat everywhere makes it easier to access conversation with multiple AI providers directly from any page being browsed. SumizAI turns valuable fragments of such conversations into ai notes saved as Markdown files in a vault the user owns, ready to search and reuse later. A user browsing the web with Ai Chat everywhere can separately use SumizAI to build a lasting archive of ai notes from the most valuable answers encountered while browsing.

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

• Ai Chat everywhere 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.
• Ai Chat everywhere is open source, and SumizAI is not. If reading the source is what decides it for you, that is a real argument for Ai Chat everywhere. The guarantee SumizAI offers instead is structural rather than legal: the notes are Markdown files in a folder you chose, so they open in any editor whether or not the application is running.
• AlternativeTo's description of Ai Chat everywhere 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 Ai Chat everywhere. SumizAI runs on macOS, Windows, iOS and Android.
