Collections
Chat across multiple documents. With citations that name their source.
Bundle documents from your Sidenote library into a Collection and chat, summarise, and build glossaries across all of them at once. Every answer is grounded in passages from the member documents; every citation names the document it came from.
When a single document isn’t enough
The question you actually have rarely fits in one document.
Single-document chat is great when the answer lives on one page. But most real questions don’t. Have we ever discounted X by more than 10%? spans pricing pages, customer contracts, and a case study or two. Why did we pick Postgres? spans an ADR, an RFC, and a six-month-old PRD.
Collections let you stop opening tabs. Group the documents that belong to a question, then ask the question once — Sidenote queries across every member document and tags each citation with the doc it came from.
How it works
Build it, open it, query it.
The signature feature
Citations that name their source.
In single-document mode, clicking a citation chip scrolls the current tab to the highlighted passage. In Collection mode, the chip carries the source document with it.
Sidenote checks whether that document is already open in one of your tabs. If it is, the highlight happens there in place — no new tab. If it isn’t, Sidenote opens the document in a new tab (the Sidenote viewer for uploaded PDFs and DOCX renders, the original URL for articles and live wiki pages) and highlights the passage once the page is ready. Either way, one click gets you to the source.
Use cases
When teams reach for a Collection.
- Research projectsBundle a set of arXiv papers, conference talks, or working drafts and ask synthesising questions across them. Each citation names the paper, so you can trace every claim back to a single author.
- RFP and proposal responsesPRDs, case studies, the pricing page, the security overview — all in one Collection. When a prospect asks a question, query the bundle once and cite the doc.
- Codebase contextArchitecture decision records, RFCs, runbooks, the deploy doc. Ask “why did we choose Postgres over DynamoDB?” and Sidenote pulls the answer from the ADR while citing the design doc that informed it.
- Support knowledge baseA curated Collection of policy pages and help docs. When a complex ticket comes in, query the bundle as one — fewer tabs, faster answer, every claim quoted.

FAQ
Common questions about Collections.
How many documents can I put in one Collection?
It depends on your tier. The free tier doesn't include Collections at all. Trial allows 3, Pro 5, Pro+ 10, Pro Max 25, and admin accounts have no cap. The size limit is per Collection — you can have any number of Collections, each holding up to its tier limit.
Can the same document live in multiple Collections?
Yes. Collections reference your library — they don't copy it. A single document can belong to as many Collections as you like, and removing a document from one Collection doesn't affect any other.
Does querying a Collection cost more than a single-document chat?
On paid tiers, yes — a chat turn against a Collection counts once per member document against your monthly chat-turn cap. A question put to a 5-document Pro Collection uses 5 of that month's chat turns. Summarise and glossary reuse cached per-document results where possible, so only the cross-document synthesis is a fresh call.
How do citations work when I query a Collection?
Every citation carries the source document. If that document is the active browser tab, clicking the chip scrolls and highlights in place — the same as single-doc mode. If it's a different document, Sidenote opens it in a new tab and highlights the passage once the page is ready. Either way, one click gets you to the source.
What happens if I delete a document that's in a Collection?
It silently leaves every Collection it belonged to. The next time you query that Collection, the membership signature has changed so the synthesis re-generates — you won't see stale citations pointing at a document that's no longer in your library.
Can I share a Collection with my team?
Not yet. Collections are per-account today. Shared team libraries are on the team-plan roadmap alongside SSO and admin controls.
