Sidenote vs Hebbia
Hebbia proved that citation-first, verifiable AI is what serious document work demands. Sidenote applies the same thesis in your browser: server-verified citations, self-serve, from £10 a month.

Should you use Sidenote or Hebbia?
Choose Sidenote if…
You're an individual or a small team and you want the verifiable-citations approach on the documents you actually read: PDFs, wikis, filings, papers and web pages in your browser. Self-serve, public pricing from £10/month, and every cited quote checked verbatim against the source before you see it.
Choose Hebbia if…
You're buying for an institution: analysis across whole data rooms and filing sets, connections to financial data providers, firm-wide agent workflows, and an enterprise deployment with the security review to match. That's what Hebbia is built and priced for.
The honest framing: this isn't a features fight, it's an audience split. One is procured by firms; the other is installed by people.

Four rows go to Hebbia, and we are not pretending otherwise; see Where Hebbia is the better tool below. The click-through row is a partial rather than a no because Hebbia does trace findings back to their source documents; that trace lives inside its own platform, while Sidenote scrolls and highlights the passage on the live page you're reading. On Sidenote's side the cross-document row is powered by Sidenote Collections, and the verification behind the citation rows is explained in what verified citations mean.
Same thesis. Very different front door.
Hebbia made the case, on Wall Street of all places, that AI over documents is only worth trusting when every answer traces back to its source. Its Matrix platform runs cited analysis across thousands of documents for asset managers, investment banks and law firms. It's bought the way enterprise software is bought: a demo, a sales process, a quoted contract, a rollout.
Sidenote takes the same conviction and puts it one click away. It sits in your browser's side panel, reads the page or PDF you already have open, and answers with citations that are verified server-side: every quote must match the document text verbatim or the citation is dropped. Click one and the live page scrolls to the highlighted passage. No procurement, no demo call; a free tier and £10 a month.
A private-equity associate at a Hebbia customer gets Matrix for the deal room. The same associate reading an analyst note, a news article or a company wiki page at 9pm gets no verification at all. Sidenote is for that second reading: the everyday documents in your browser, cited and checkable, on your own account.
Where Hebbia is the better tool.
Hebbia is a serious, institution-grade platform, and for institutional work it is simply the right category of tool:
Institutional scale & rigor
Matrix runs analysis across thousands of documents (data rooms, filings, transcripts) with traceability designed for institutional review, and the certifications large firms require, including SOC 2 Type II and ISO/IEC 42001.
Agent workflows for a whole firm
Hebbia's Skills & Agents let a firm encode its recurring processes once and have agents run them continuously. Sidenote answers questions when you ask; it doesn't run your firm's workflows in the background.
Finance-native data under one roof
Private documents, public filings and financial data providers connected in one place, plus API and MCP connectors for internal tools. Sidenote reads what's in your browser; it isn't a data platform.
