Quivr

An open-source engine for content that keeps arriving: store it, search it, and get alerted when something new matches a topic you follow.

You send Quivr documents (news articles, emails, posts, PDFs), or let it collect them from RSS feeds, Microsoft 365 mailboxes and X lists. Quivr keeps every version, makes each document searchable within seconds, and checks it against your saved alerts. Your application talks to Quivr over an HTTP API; Quivr has no user interface of its own.

Quivr is developed by The Vibe Company, the AI agency created by the Quivr team.

Status: Quivr 2. From 2.0.0 on, the HTTP API (/v0) stays compatible across 2.x releases and upgrades keep your data in place; see Versions and compatibility and Known limits.

What you can do with it

• Collect content you send one by one or in batches, or that Quivr pulls from sources on a schedule. Files such as PDFs are read by plugins.
• Search by keywords, by meaning, or both. Every result points to the exact passage, document and version it comes from, so you can always cite it.
• Follow a topic. Save an alert such as "harbour strike" AND (ferry OR port), or a plain-language description, and Quivr records every new document that matches, with the reason. Your application reads the matches or receives them as signed webhooks.
• Keep history. A correction becomes a new version; the old one stays readable. A withdrawn document leaves search at once, and alerts that caught it are told.
• Plug in your own logic. File formats, sources, embedding models, ranking and alert rules are plugins: small HTTP services you can replace, in any language.
• Let AI agents use it. quivr mcp lets an agent search Quivr and quote what it finds, with the source of every passage.

How it works

flowchart LR
    sources[Sources and<br/>your application] -->|documents| api[Quivr API]
    api --> store[(PostgreSQL + object storage<br/>every version, kept safely)]
    store --> worker[Quivr worker]
    worker <-->|read, cut, embed,<br/>rank, judge alerts| plugins[Plugins]
    worker --> index[(Search index)]
    app[Your application] <-->|search, alerts, changes| api

Quivr confirms a document only once it is stored, then processes it in the background: an outage delays processing but never loses what was confirmed. The search index can always be rebuilt from storage. How Quivr works explains the parts and the guarantees.

Try it

You need Linux on x86_64 or a Mac with Apple Silicon, Docker with Compose v2, the Go version in go.mod, Python 3.12 with venv, and jq. The first start downloads about 1 GB.

git clone https://github.com/The-Vibe-Company/quivr.git && cd quivr
make dev                 # start Quivr and its dependencies in Docker
eval "$(make -s env)"    # point this shell at the API, with a local key

Then follow the Quickstart: create a collection, add an article, find it by keyword and by meaning, and get alerted on a topic, in about fifteen minutes. make demo adds a web app on top, at http://127.0.0.1:5183 (quivr-search/).

To install Quivr on a server from published images, without a checkout, see Run Quivr on one machine.

Contributing

Read AGENTS.md for the rules and CONTEXT.md for the domain vocabulary, then the contributor start page. Run make check (about two minutes, no Docker) before pushing; make verify runs the end-to-end journeys on an isolated stack. Pull request titles follow Commitizen, for example feat(ingestion): accept record versions.
