Private beta · Built for independent contractors

From first request
to final invoice.

Kernel is a work operating system for people who juggle many clients. It turns email, Slack, and meeting requests into suggestions you approve, keeps every client's work on one board, plans it around your calendar, hands tasks to your AI agents, and bills from the time you actually record.

Kernel tasks board with lifecycle columns for Inbox, Blocked, Backlog, Ready, Doing, and Done. Cards from several clients show their client keys, organization and project names, priority, and due dates.
One board for every client, and the day planner on a phone

Work comes in

Requests arrive from everywhere.

Kernel reads the places work already lands and turns it into suggestions you review. Nothing becomes a task until you say so.

Plan the work

A plan that respects your calendar.

One board for every client, timeboxes placed around your meetings, and routines that schedule themselves.

Kernel planner in week view. Five weekday columns hold planned task blocks, tracked time, and a locked invoice-prep block, with a Tasks sidebar listing what is up next for each client.

Track the time

Hours you can stand behind.

Every start is a timebox. Entries carry their client, project, and billability, and drafts wait for your review.

Kernel time summary for August 10 to 16 showing total tracked, billable, unpriced, and daily average tiles above a duration-by-day chart stacked by billability.
Time summary

Bill and report

Bill from what actually happened.

Rates, invoices, and client-facing reports are built from the same recorded work, never retyped.

Recreated with sample data

Agents

Built for the agents you already run.

Coding agents and AI assistants get the same work records as the web app, through a documented API and a small command-line companion. Credentials and provider connections stay behind your signed-in session.

  • Scoped keys. API keys are workspace-scoped, expiring, rate-limited, and shown once. Choose read-only or full work access.
  • Contract first. An OpenAPI 3.1 document, an LLM-oriented Markdown guide, and a downloadable Kernel skill ship with every deployment.
  • Hand-offs from a task. Pair your Mac with krnl, then send a task to Codex or T3 Code and follow the thread from Kernel.
# pair this Mac with your workspace
$ pnpm add -g @supercorks/krnl
$ krnl login
$ krnl connect t3code

# read the same tasks the planner shows
$ curl https://app.krnl.work/api/v1/tasks \
    -H "Authorization: Bearer $KERNEL_API_KEY"

# contract, guide, and skill
$ open https://app.krnl.work/developers/api

Across the app

The foundations under everything.

Clients and projects, one search for every record, and an app that works on your phone.

Press ⌘K, or Ctrl+K on Windows and Linux, in any of Kernel's main views to search tasks, clients, projects, documents, files, meetings, invoices, habits, and time notes.

Kernel search open over the tasks board with the query “launch”. Six results are grouped as Tasks, Files, Meetings, and Docs. Each task shows its client key, client and project, a mark in the project's color, and a status of Doing, Blocked, or Done. The document result previews the sentence that contains the word.

Integrations

Connected to where work arrives and where it is reported.

Every connection is optional and separately authorized. Reading and writing are distinct permissions, and you can disconnect at any time.

What each integration can read and change

Your data

Useful context. Deliberate choices.

Google sign-in identifies you and nothing more. Calendar, Gmail, and Slack access are separate authorizations you grant on purpose, and each private workspace stays separate from everyone else’s.

How Kernel handles your data

Google Calendar

See availability and manage events on calendars you authorize.

OPTIONAL

Gmail

Read connected email for reviewable suggestions, and send a reply only when you press Send.

OPTIONAL

Slack

Read the conversations you include, and post a reply only when you press Send.

OPTIONAL

Google sign-in uses basic identity details. It does not, by itself, grant Kernel access to your inbox or calendar. Disconnecting and deleting imported data are separate controls.

Questions

Before you ask.

Can I use Kernel today?

Not yet. Kernel is a private beta under active development, and there is no public sign-up. This site describes the product and publishes its policies while the beta is being built.

Who is Kernel for?

Independent contractors and solo consultants who work across many client organizations and bill for their time. Kernel is a personal workspace; shared team workspaces are not part of this beta.

Does Google sign-in read my Gmail?

No. Signing in uses basic Google identity details through Clerk. Calendar and Gmail connections are separate, optional authorizations. The privacy policy explains the difference.

Do AI suggestions take action for me?

Inbox suggestions are drafts for you to review. You decide whether to accept them as tasks or calendar events. When these optional features are enabled, relevant content and context are processed by external AI services, as described in the privacy policy.

Can I disconnect or remove imported data?

Yes. Disconnecting and deleting imported data are separate actions. Disconnect first to stop future intake, then remove imported data where the feature is available. Accepted work and some history can remain. Read the full deletion instructions.

Are the screenshots and demos real?

The screenshots are captured from a real Kernel build running with representative sample data. The animated demos recreate the same screens with the same kind of data. The client names, tasks, and hours are fictional, and none of it comes from a real account.

Private beta

Built one week at a time.

Kernel is being built by one person who runs a contracting practice on it every day. When the beta opens, this page will say so.
