SumizAI vs DockyAI

What DockyAI is

DockyAI (Docky) is a browser extension (Chrome, Edge) in the form of a sidebar that brings access to ChatGPT-3.5 and GPT-4o into one place, removing the need to switch between browser tabs while researching, reading, and writing. It answers a very specific productivity problem: attention scattered across dozens of open tabs, some of them AI tools, some of them the content that actually needs processing.

The sidebar handles several functions at once: answering questions, reading and summarizing documents, extended search, writing assistance, image generation. Having that set of features in one always-available sidebar sets DockyAI apart from a plain ChatGPT browser tab — the user doesn't lose the context of the page they're currently browsing, because the assistant sits "next to" it rather than in a separate window.

The pricing model is paid, with a limited free daily allowance — a typical approach for tools using costly language models as a backend, where the provider has to balance API request costs against the price for the end user. Anyone looking for a purely free alternative (directly via the ChatGPT interface, or competing extensions with a more generous free tier) has plenty to choose from on the market.

Compared to the native ChatGPT interface, DockyAI's advantage is availability from any web page without switching tabs — the cost is dependency on a browser extension, which can stop working after a major browser update or be discontinued by its creator, unlike an official app from the model provider itself.

For research and quickly summarizing long pages or documents, DockyAI works as a practical substitute for manually copying content into a separate chat window — which saves time on its own, though it doesn't replace an organized ai notes archive with the ability to later search through gathered material.

It's worth remembering that DockyAI is an access layer to existing models (ChatGPT), not its own proprietary language model — so answer quality depends on what the underlying model provider offers, and the tool's added value lies in the interface and browser integration, not in the intelligence of the answers themselves. Anyone keeping an ai notes archive elsewhere can treat DockyAI as a bridge between reading a page and a quick model consultation, manually moving the result into that destination ai notes archive afterward.

Competitors in this niche (extensions like Sider, Monica) offer a similar sidebar feature set with access to multiple models at once — DockyAI stands out for simplicity and focusing on two specific OpenAI models instead of offering a wide choice of providers, which can be an advantage for people who don't want to decide which model to use.

For users already keeping their own these notes in a separate system, DockyAI works well as a helper tool for quick answers while browsing the web, rather than as a place to permanently store the results of that work.

In short, DockyAI is a convenient, paid AI assistant in browser-sidebar form that shortens the distance between browsing content and talking to a language model — a practical add-on for everyday web work, though not a direct competitor to full-fledged these notes systems.

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

• DockyAI 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.
• DockyAI 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 DockyAI 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 DockyAI. SumizAI runs on macOS, Windows, iOS and Android.
