Quiet observation,
precise suggestions,
your approval.
LVIS reads signals from your mail, calendar, meetings, documents, and internal APIs, and only speaks up at the right moment. Every write action starts with your approval.

The App
A work assistant that runs on your own PC.
LVIS is a desktop AI work host. Reading signals, drafting proposals, and carrying out results all happen on your device. Your PC is the stage — not the cloud.
Local-first · on-device
The local indexer indexes documents on your PC right on the device. Document contents never leave your machine, and signals are first classified read-only.
Plugin architecture
Add only the plugins you need, each isolated in its own runtime. Nothing is forced on you, and swapping one out after review is easy.
Approval-first execution
Observation and suggestions happen quietly, while write actions pass through a risk-labeled approval gate. Execution always begins with your decision.

A Day with LVIS
Follow the flow of a day, together.
It quietly watches every signal as it comes in, and only shows itself at the right moment.
08:00
work-assistant · ms-graph
Before your day begins, today's briefing is ready.
LVIS combines yesterday's mail, today's schedule, and still-open tasks into a morning briefing. See what to prepare before meetings and which emails need a reply, at a glance.
09:14
ms-graph · work-assistant
Before an email becomes a meeting.
LVIS reads a new email's headers and body to identify a meeting request. It checks open time slots and rooms too, so you can reply, book, and add it to your calendar in one click.
10:55
meeting · work-assistant
Right before a meeting, a prep card opens first.
15 minutes before a scheduled meeting, a prep card automatically surfaces the schedule, agenda, video link, and a summary of the last meeting. It never exposes the body text, and the OS notification stays a short one-liner.
11:47
meeting · agent-hub
When a meeting ends, the summary is ready first.
LVIS detects the meeting's end, transcribes it, and automatically organizes a summary and action items. It estimates owners and deadlines and moves them straight to Agent Hub's kanban board.
14:32
work-assistant · agent-hub
One more check with you before it runs.
LVIS combines the afternoon's signals into kanban cards for tomorrow's to-dos. Writing to the board also has to pass an approval dialog. The higher the risk, the clearer it's shown.
15:30
work-assistant · meeting
Want help putting together your weekly report?
LVIS gathers this week's meeting summaries, completed actions, and next week's schedule into a weekly report draft. The draft follows your team template's tone and length, and whether to send it is always your call.
17:00
work-assistant
Ready to wrap up the day?
LVIS walks you through checking tomorrow's schedule, tidying up unfinished tasks, and writing follow-up notes in one flow. Once the wrap-up check is done, LVIS goes quiet too.
20:00
local-indexer · work-assistant
While you're away, LVIS keeps working.
When idle time is detected, LVIS quietly handles new document indexing, meeting summary enrichment, and email sorting. It yields the moment you return — closer to background cleanup than active work.

Architecture
The user is always on top. Below, the host and isolated plugins do the work.
Signals flow up from the bottom, and decisions flow down from the top. Every layer is separated by an explicit permission boundary.
User
Decision · approval · keyboard input
High-risk tools pass only with a stated reason and explicit approval.
LVIS Core
Host · approval gate · tool runtime · audit
Every tool call goes through policy evaluation, a permission check, and an audit log.
Plugins
Isolated runtimes · Host API access only
Plugins can't touch each other's data directly — they only call the Host API with explicitly granted permissions.

Surfaces
Two surfaces, one flow.
The app gathers signals, the Marketplace adds capabilities, and Agent Hub records the results.
Marketplace
Discover and install plugins.
Check versions, distribution packages, and install policies in one place. The app downloads, verifies, and registers the plugins you need through this catalog.
Open the marketplacePersonal Agent Hub
Organize your work on a kanban board.
To-dos, approval requests, and daily reports your agents create are collected on a personal kanban board inside the LVIS app. See the flow at a glance across To do · In progress · Done — execution always starts with your approval.

Roadmap
Ends July 31From static integrations to autonomous collaboration.
Plugins evolve from simple tool-calling modules into connectors and autonomous sub-agents. We're rolling out six vision axes across v1 through v4. Timing isn't finalized yet.
- 01
Plugin → Connector + UI
We're going beyond tool calls, expanding into first-class connectors that offer bidirectional streaming UI, their own workspace, and interactive widgets.
- 02
Plugin = Sub-agent
Plugins act autonomously with their own prompts, tool sets, and decision loops. Delegated scope is isolated by the agentApproval permission scope.
- 03
Idle-time Intelligence
Detects OS idle state to handle indexing, summarizing, and briefing prep in spare time. Yields immediately the moment the user returns.
- 04
Capability Pack
Bundles today's four separate catalogs (plugin · agent · MCP · skill) into a single deployment unit. Users only need to install once.
- 05
Trigger DSL
Extends shutdown/schedule triggers into event trees, condition combinations, debounce, and weighting. Routines become a small workflow engine.
- 06
Hooks — Lifecycle + Interceptor
Extends today's start/stop-only lifecycle to install, activate, tokenRefresh, pre/postToolCall, and onPermissionGranted. Establishes a standard point where external code can safely hook into the flow.

This roadmap is directional. Detailed milestones, code entry points, and status are updated with quarterly retrospectives in the roadmap docs .
Pilot
Start with one small team, then scale to the whole org.
Validate the flow with a single team's signals, then grow the Marketplace catalog as you expand across the organization. Connecting mail, calendar, and meetings one step at a time is plenty to start.
