OmniBrief
Add to Chrome
A ZumiLabs tool · built by five people who hated open tabs
OmniBrief is a private reading queue that summarises articles, PDFs and YouTube videos before you commit to them. Queue links as you browse, get short written or audio briefs, and file the useful ones into a searchable archive that never leaves your machine.
Core capabilities
Six things OmniBrief does well — and a few it deliberately refuses to do. We kept the surface small on purpose.
Right-click any article, PDF or YouTube URL and add it to your queue. OmniBrief reads the page and hands back a plain-language triage: what it is, how long it'll take, and whether it's actually about the thing you searched for. No more twelve tabs "just in case".
Every saved item can be spoken aloud with on-device speech. Good for screens off, walks, and multitasking.
Save the useful briefs and OmniBrief builds a searchable personal library — an offline vector index, so semantic search works even with the plug pulled.
Point OmniBrief at the model you trust — Chrome's built-in Gemini Nano by default, or hand a private summary to Claude, ChatGPT or a local runtime. Your call, every time.
Choose a cloud LLM if you want, but the default keeps everything on device. No page content is uploaded unless you deliberately ask for it. Your keys, reading history and search stay yours.
Interaction flow
Three moves you already make — queue, brief, keep — with the friction taken out.
Paste a URL or right-click to add. OmniBrief ingests articles and YouTube transcripts alike, and it'll grab local PDFs too if you hand it the file.
Short summaries generated on-device in seconds. Prefer your ears? Have it read the brief aloud with adjustable speed while you do something else.
Save the good ones into a smart, searchable library. Semantic search finds the note you half-remember — offline, months later.
Our stance
Most "AI reading tools" are a pipe to someone else's server. We took the opposite bet: the model runs in your browser, the index lives on your disk, and nothing is phoned home. If that means we can't sell your reading habits — good.
Straight answers
OmniBrief checks for the on-device model and walks you through turning it on the first time you run a brief. If your Chrome build doesn't ship it yet, you can point OmniBrief at a cloud model instead — the choice is always yours.
No. Page content is processed locally by default, and nothing is sent to us. The only time text leaves your machine is if you deliberately choose a cloud LLM for a specific link — and then it goes to your provider, not to us.
Start Ollama with an origin that allows the extension (set OLLAMA_ORIGINS to include the extension origin) and OmniBrief will connect to your local runtime. There's a step-by-step check in the diagnostics panel.
Chrome blocks extensions from reading file:// URLs unless you grant it. Toggle "Allow access to file URLs" on the OmniBrief extension page and local PDF briefing starts working immediately.
Yes. Add your own API key in settings and pick the model per link. OmniBrief hands over just the summary request — it never stores your key anywhere but your own browser storage.
Install OmniBrief, queue the next thing you were about to open, and let it tell you whether it's worth your afternoon. Free, private, and off your screen when you want it.
