Comparison

Sidenote vs Dust

Both cite the documents they answer from. The difference is scale and setup: Dust is a platform your company uses to build custom AI assistants and agents on top of your connected apps, while Sidenote is a per-person reader that rides along on whatever page or PDF you already have open — no admin rollout, no assistant to configure, and a free tier to start on your own.

Sidenote

A reader that rides along in your browser, answering from the document you already have open.

Dust

A platform for building custom AI assistants and agents on your connected company data.

The short answer

Should you use Sidenote or Dust?

Choose Sidenote if…

You want to read and question the specific document in front of you — a page, a private wiki, a PDF — with citations that scroll to the exact passage, starting free on your own with no assistant to build or IT project to run.

Choose Dust if…

You are a team that wants to build and configure custom AI assistants and agents wired into your connected apps — Notion, Slack, GitHub, Drive and more — deployed company-wide by an admin.

One is a platform for building assistants across your company's connected data; the other reads the one document in front of you and shows you exactly where each answer came from.

Several rows go to Dust, and we are not pretending otherwise — see Where Dust is the better tool below. Dust's assistants do link back to the documents they drew an answer from, but that is a link to the source, not a scroll-and-highlight of the exact passage on the live page, so that row is marked no rather than partial. The cross-document row is powered by Sidenote Collections.

The core difference

Build an assistant on your company data, or read the document in front of you.

Dust is a platform for building AI assistants and agents. An admin connects your company's apps — Notion, Slack, GitHub, Google Drive, Confluence and others — and a team configures assistants that answer and act on that connected data, deployed to everyone at the company.

Sidenote is not an assistant platform. It sits in the browser side panel and answers from the single document you already have open, then scrolls the live page to the exact passage each claim came from and highlights it. There is nothing to configure and a free tier to start on your own.

The difference in one example

Ask "what did we decide about the Q3 roadmap?" A Dust assistant, configured to search your connected Notion and Slack, returns an answer with links back to the documents it drew from. Sidenote reads the exact Notion page you already have open, answers, and highlights the sentence that proves it — no assistant to configure, right where you are reading.

Giving credit

Where Dust is the better tool.

Dust is a serious, well-built platform for company AI assistants, and there are things it does that a per-person browser reader simply does not. If these are what you need, Dust is the stronger choice.

Custom assistants & agents on company data

Dust lets a team build and configure its own AI assistants and multi-step agents, wired into connected apps like Notion, Slack, GitHub and Drive. Sidenote reads the documents you personally open — it has no assistant builder or agent framework.

Company-wide deployment

An admin connects your organisation's apps once, and every teammate gets assistants grounded in that shared, permission-aware data. Sidenote is a per-person reader you install yourself, with nothing to roll out to a team.

Developer API & workflow automation

A developer API and automation hooks let teams wire Dust's assistants into their own tools and workflows. Sidenote stays a focused reader rather than a platform to build on.

FAQ

Sidenote vs Dust — common questions

For an individual who mainly wants to read and question the document in front of them, yes. Dust is a platform your company uses to build custom AI assistants and agents on top of your connected apps — Notion, Slack, GitHub and similar; Sidenote is a per-person browser reader that answers from the page or PDF you already have open, with citations that scroll to the exact passage. If you need a platform for building company-wide assistants, Dust fits; if you want to read a specific document and verify every claim, Sidenote does.
Dust is built around connecting your company's own apps and data sources — Notion, Slack, GitHub, Google Drive, Confluence and similar — so its assistants answer from what your team has connected, not from open web search. Sidenote is not a web search engine either, but it will read and answer questions about any web page or article you have open in your browser.
Both link back to their sources. Dust's assistants cite the documents they drew an answer from, with a link back to the source. Sidenote cites the exact passage inside the document you are reading — click a citation and it scrolls the live page to that sentence and highlights it — and it drops any cited quote it cannot verify against the document before you see it.
No. Dust is typically deployed by an admin who connects your company's apps, configures the assistants and rolls them out to a team. Sidenote installs as a browser extension in seconds, signs in with a magic link, and has a free tier — you can start on your own without involving IT.
No. Dust's core strength is letting teams build and configure their own AI assistants and agents on top of connected company data. Sidenote stays a focused reader — it doesn't have an assistant builder, workflow automation or an agent framework.
Dust uses quote-based enterprise pricing set per company, with no public free tier that we could confirm — check Dust's site for current plans and figures. Sidenote is freemium: a free tier forever, a 7-day Pro trial with no card, and paid plans from 10 pounds a month.
