One subscription · every tool

Every source Sidenote reads.
One assistant, every answer cited.

One browser extension reads Confluence, Notion, SharePoint, Google Docs, PDFs, Word docs and the open web, on a single subscription instead of an AI fee per platform. Every answer cites the exact passage it came from, so you can check it in a click.

The problem

One AI bill per platform doesn't scale.

Atlassian sells Rovo for Confluence. Notion sells Notion AI. Microsoft sells 365 Copilot for SharePoint. Google sells Gemini for Workspace. Each is a per-seat add-on locked to its own silo, and none of them can answer a question that spans your wiki and your spec and the PDF a vendor just emailed you.

Sidenote takes the opposite approach: one lightweight extension that reads whatever document is in front of you, connected account or open tab, and grounds every answer in a citation you can verify.

One extension, every source

Read the tools you already use.

Connect an account once, or just open a tab. Each source has a dedicated guide:

Private by design

Read-only, per-document, never crawled.

01

Read-only, always

Every connection uses read-only scopes or your own browser session. Sidenote never writes, posts, or changes anything in your accounts.

02

Only what you open

Nothing is crawled or bulk-read. A document is indexed only when you open or ingest it - and disconnecting a source deletes its token immediately.

03

No model training

Your content is never used to train models. Tokens are encrypted at rest and data is stored in a UK region with per-account row-level security.

Cited across tools

Answers you can check - wherever they came from.

Sidenote never just asserts. Every answer carries citations that scroll and highlight the exact passage in the live document. And with collections you can bundle documents from different tools and ask a single question across all of them: the wiki page, the spec, and the PDF, answered together and cited individually.

One subscription covers every source. See the pricing tiers: there's a free tier forever and an opt-in 7-day Pro trial, no card required.

FAQ

Multi-source questions, answered

For most sources, no. Sidenote is a browser extension (Chrome, Edge and Firefox) each person installs themselves, and it reads Confluence, Notion and Google Docs from your own signed-in session or via each provider's official read-only API. The one exception is SharePoint & OneDrive: organizations that restrict third-party app consent may need a one-time administrator approval before anyone can connect, after which every user signs in individually.
No. Sidenote is per-document and opt-in: it only reads a page or file once you open or ingest it. It never crawls, lists, or bulk-reads your accounts, and it never writes or posts anything back. Each connection is read-only, and disconnecting it immediately deletes the stored token.
Each of those is a per-seat add-on locked to a single platform: to cover Confluence, Notion and SharePoint you'd pay for three separate AI licenses, every month, for every person. Sidenote is one subscription that works across all of them (and PDFs, the web, and Word docs) from the same browser extension.
No. Anthropic (the model provider) and Voyage AI (embeddings) both run with no-training defaults on the API tiers Sidenote uses, and Sidenote never fine-tunes models on user content. OAuth tokens are encrypted at rest and content is stored in a UK (eu-west-2) region with row-level security isolating every account.
Yes. Group documents from different sources into a collection (a Confluence runbook, a SharePoint spec and a Google Doc, say) and ask one question across all of them. Every answer cites the exact source passage, and the citation chip scrolls the live document to it.
Confluence, Notion, SharePoint & OneDrive, and Google Docs for connected accounts, plus anything in your browser: PDFs (including scanned ones via OCR), web articles, Word documents, and Slack canvases you ingest. Each has a dedicated guide linked above.
