The place work gets done.
Plexii gives every piece of work its own desk: the doc, the numbers, the research, the people and an AI assistant that shows its sources, side by side on one canvas.
Free forever for personal use. Mac and Windows. Prefer a guided tour? Join a live session or book a demo.

The reference you needed was in the window you shut an hour ago.
Every switch between apps costs you the thread you were holding.
You rebuild the same picture of the work every time you come back to it.
One task. One desk.
Modern work means running a dozen tools that don't talk to each other. Plexii brings them together around the thing you're actually doing.
Start a desk
New task, new desk. Describe it in a sentence and Plexii sets it up with the right work widgets, docs and pages.
Do the work in one place
Write the doc, build the sheet, open the sites, meet the team and ask Plexii, all on the same canvas.
Come back to it
Close the desk and the clutter goes. Open it tomorrow and everything is where you left it, with a one-line summary of the next step.
Four ways to get started.
Explore on your own, install it today, or let us show you around.
Everything the work needs, already on the desk.
A full office suite, an assistant that knows your files, and the meetings, mail and people around the work. One app instead of a dozen.
The Desk
Every task gets its own desk: notes, tables, files, browser windows, timers, diagrams and mind maps, side by side. Desks live in rooms.
The deskPlexiiOffice
PlexiiWrite, PlexiiCells, PlexiiDeck, PlexiiDraw and PlexiiDesign, with real .docx, .xlsx and .pptx in and out.
The office suitePlexii assistant
Grounded answers with citations, and changes you approve card by card.
The assistantFocus
Every task that needs you, captured from anywhere, in one list.
Your tasksPlans and calendar
Milestones, timelines and a time-blocking calendar.
PlanningMeetings, chat and calls
Meet from any document, with transcripts filed for you.
CommunicationMail and signing
Your mailbox and e-signatures, next to the work.
Mail and PlexiiSignPeople and teams
A real-name directory and a live People Map.
PlexiiTeamAI that shows its sources and asks before it acts.
Plexii answers from your own documents, sheets and notes, with a citation for every claim and a trace of what it read. When the answer implies a next step, it drafts it as a card. Nothing lands until you apply it.
- Grounded in your work, not a blank chat window. When it can't find something, it says so.
- Review before anything changes. Apply cards one at a time or all at once.
- A Stop button that always works when Plexii does multi-step work for you.

Your work lives on your machine first.
Plexii is local-first and works offline. Your work syncs to your account while you are signed in, and the vault is sealed with a master password only you know.
- Bring your own Anthropic key and prompts go straight from your machine to Anthropic.
- Or let Plexii run it for you on the AI credits every plan includes each month, with your prompts never used for training.
- No third-party analytics. Usage data and crash reports are first-party and off unless you turn them on.
Sync is encrypted in transit but not end-to-end encrypted. Read the privacy details.
See it built for your work.
Pick your role and Plexii builds the desk you'd use, live, with your own kind of work on it.
