Prose, a real drawing canvas, and your source files — PDFs, datasets, diagrams — as equal parts of one page, not three apps bolted together. A DocuShark document acts like a mini-Google-drive in one file: it opens in under a second, and any AI agent you point at it makes real edits alongside you. The page engineers and researchers always wished they had.
See how it works →The tools we all use are genuinely good at one thing each — Notion at prose, Miro and Excalidraw at the canvas, your drive at the files. The cost is the tab-hopping between them. DocuShark brings all three onto one page as first-class peers — three dimensions of the same document. A DocuShark document acts like a mini-Google-drive in one file. Once you’ve worked this way, juggling three apps feels like a step down.
Headings, code blocks, callouts, tables. Write in Markdown or don’t — the editor feels exactly like the one you already use, and never makes you think about it.
Flowcharts, network topologies, UML, database schemas — nearly 200 first-class shapes, the depth of Visio with none of the weight. Draw thousands of them and it never stutters. This is an editor for people who diagram for a living.
Papers, datasets, figures, instrument output — embedded as first-class blocks that render in the page, not flat thumbnails that bounce you to another tab. They load straight from storage, so even a 40-page PDF opens at once.
No marketing renders. No staged screenshots. Real documents built by real users in the production app — the kind of work that wasn’t possible on a page until the page was rebuilt.
Network topologies, service maps, database schemas — on a canvas that handles thousands of shapes without breaking a sweat.
Onboarding flows, incident playbooks, decision trees — auto-routed connectors keep the lines honest.
Rich text on the left, shapes on the right, and your AI can edit both — exactly how DocuShark is used in practice.
Active documents live in memory and stream to you over a live connection — no full-page reload, no “Loading content…”, no spinner. Documents that aren’t open yet pull from storage in tens of milliseconds and stay warm for the session. Embedded files come straight from object storage to your browser, so even heavy PDFs and datasets appear at once.
Open documents live in the relay’s RAM as CRDTs. Opening one is a handshake and a state push — not a database query.
Documents that aren’t resident load from object storage in tens of milliseconds, then stay warm for the rest of your session.
Embedded files stream straight from storage to your browser — the bytes never route through our servers. Faster, and free to move.
The tools you already use are good at what they do — this isn’t about beating them. It’s about ending the tab-hopping between them. Work you’ve already done comes in; finished documents go out to wherever people already read. Your tools, surfaced on your page, never rebuilt.
Mermaid, drawio and Excalidraw arrive as native, editable shapes — not images of shapes.
A Notion page, read-only inside your document, refreshed when you ask and always linked back to the source.
Publish a read-only link. Pasted into Slack, Discord or anywhere that reads link previews, it shows itself.
DocuShark isn’t three products. It’s one engine — canvas, prose, data, imports, AI — that rearranges itself into a layout for the work in front of you. We built it first for engineers and the researchers right beside them, then opened the same page to everyone — because a runbook you ship on Tuesday and a thought you catch on Sunday deserve the same tools.
Where the document is the deliverable — RFCs, architecture, runbooks, schemas. Diagrams as code, an AI that edits the canvas, and an import on-ramp that brings every diagram you already have.
Source files — PDFs of papers, CSVs of data, recorded sessions, raw figures — live right next to your docs and canvas. Embed a 40-page PDF, drag a highlight onto the canvas, keep editing. Your supporting material doesn’t have to live somewhere else anymore.
The same page, quieted down — for notes, flowcharts, and the diagrams you sketch once and reach for later. No technical knowledge required: it just opens, just works, just stays out of the way, on your phone or your desktop.
Point any AI agent — Claude, ChatGPT, Cursor, whatever you use — straight at a document and it makes real edits: rewrites a section in place, swaps a single block by matching its text, wires up new shapes on the canvas. Not a chat window bolted to the side — a precise toolset over the open MCP standard, editing the live document while you watch.
And not a house model. Connect whichever AI you already use — and switch whenever you like. The model is yours, the page is yours.
Every academic and every analyst has the same complaint: their tools treat citations as punctuation. DocuShark treats every cited source as a first-class entity — with metadata, deduplication, and a stable handle the rest of the page refers to. Import a Zotero library, paste a DOI, switch CSL styles, let an agent resolve references programmatically. The full ingest → cite → publish loop, on one page, for the first time.
Real-time collaboration is genuinely hard to run well — which is why it’s so often the paywalled tier. We host it for you at docushark.app and kept the whole thing open source anyway, so you get the convenience without ever being trapped.
A workspace your whole team opens in the browser — no setup, no servers to babysit. We run it, keep it fast, and ship every upgrade the moment it’s ready. You could self-host the whole thing — but at a few dollars a month, sign in with one click, and fast from your nearest region, most people happily don’t.
Work entirely in your browser in local mode — no account, fully offline, your files never leave your machine. Need everything to stay inside your company network? The engine and relay are open source — run them yourself, free, for internal use.
DocuShark Cloud runs in Toronto today. Every workspace is tied to one region from day one — your documents and files never leave it. Chicago, Frankfurt, and Tokyo are next, switching on as demand in each region grows.
No per-seat feature gates, no metered clicks, no counting your documents. You pick a plan and everything that makes DocuShark DocuShark is simply yours — the only thing we ever meter is raw file storage, and it’s capped.
The whole editor, free forever — every shape and prose feature. A free Cloud workspace for a taste of sync and sharing. No credit card, ever.
Everything in the cloud, unlimited — documents, shapes, versions, AI edits, viewers and share links. Generous storage, one flat fee.
Your whole team on one unlimited workspace — everything in Solo, plus pooled storage and editors, and team member management. It grows with the team.
The only thing we ever meter is raw file storage — and it’s capped, so your worst case is known up front. Go past it and your files keep working; the meter just stops.
DocuShark prices and included quotas may improve over time. They will not get worse for existing subscribers without 12 months notice and grandfathered legacy pricing.
DocuShark lives at app.docushark.app — open the link and you’re already working. Want it in your dock or on your home screen? Install it in a click. Either way it opens instantly and keeps going when your connection doesn’t.
Straight from the browser to your dock or home screen — no app store, no installer.
Your documents and their files stay on your device. Changes sync the moment you're back.
Sign in once and move between workspaces without re-authing or juggling tabs.
Most companies our size are already burning a year on SOC 2 theatre and “contact sales” mazes. We’re not. The page comes first; Enterprise comes once a paying design partner asks for it — with a published price, dedicated infrastructure, data residency, single sign-on, and an SLA. Drop your email, we’ll write the day it’s real. No sales calls in between.
We’ve been writing into the same rectangle for thirty years and calling it progress. DocuShark is the bet that the document is worth rebuilding from the cursor up — in the open, on one engine, for everyone who’s ever wished the page would keep up with the thought.
