  • Click a tile on the Business Map to open the work behind it, or ask the Agent a question.
  • Match a receipt in Transactions and watch the counters update.
  • Open Automations and press Explain this screen, or press ⌘K and search for Kessler.

Ask across everything you have.

The agent reads your mail, contacts, projects, finances and notes, and shows each step and every record it used. It runs on a local model, so the question and the answer stay on your Mac.

The paperwork, read and drafted for you.

Receipts are read, replies are drafted and downloads are sorted while you work on something else. Each result waits for your OK before it changes anything.

    An email arrives

    Hannes from Kessler Maschinenbau asks whether their spare-parts stock could follow a forecast. The workbench files the email under a new company and a new contact.

    Forecasting our spare parts?

    Moin Lena, we hold too many parts for some machines and run out of others when a customer's line is down. Could you look at our service data and tell us what to stock?

How the automations work.

Every scheduled job follows the same five steps, from a trigger to a result you can check. Pick a job below and run it to see what each step does.

Running File SorterReady

  1. Trigger

    A schedule in macOS launchd starts the job: an interval or a cron time. Nothing has to stay open.

  2. Collect

    The job pulls what is new since its last run: mail, calendars, the Obsidian vault, downloads or bookmarks.

  3. Understand

    Where a job needs judgement, a local model reads, classifies or summarises. Plain syncs skip this stage.

  4. Propose

    Results are written as proposals: drafts, matches, categories, moves or index updates.

  5. Apply

    Imports apply directly. Anything that sends, moves or files waits in a review queue until you apply it.

Run history

  1. Email Sync + Auto-Draft1 new email, no drafts
  2. Calendar SyncNo changes

Every run is logged with what it read and what it changed, so you can always check what happened overnight.

Three layers, one direction

The app is built so that work flows one way: the automations produce it, you check it, and then you use it.

  1. Runs the work

    Operation layer

    Scheduled jobs collect new data and do the reading, matching and drafting. Evaluation shows how well the AI steps do.

    • Automations, 12 jobs
    • Evaluation, 90%
    • Run history
  2. Where you check it

    Correction layer

    Every table where results land: tasks, projects, contacts, companies, emails, transactions, receipts and invoices. You verify, fix or reject.

    • Transactions to review
    • Receipts to verify
    • Folder changes
    • Drafts
  3. Where you use it

    Application layer

    The agent, search and actions work on data you have already checked, so answers rest on records you trust.

    • Agent
    • Search
    • Actions
    • Replies
    • Doc analysis
    • Anonymization

Quietly running on your own devices.

Your data comes in, gets processed and stays on machines you own. Your Macs keep each other in sync, your phone reaches them over your private network, and a daily archive keeps every version safe. A cloud model is an option you switch on per task, not a requirement.

Questions

Who is J.AI built for?

Freelancers and consultants who run their own business: client work, the paperwork around it, and the knowledge it produces, in one place.

What does local-first mean here?

The workbench, its database, its search index and its models run on your Mac. Mail, calendar and bank data are synced to your machine, not to a J.AI server. Optional cloud models through AWS Bedrock can be switched on per task.

Which AI models does it use?

Local language models run through Ollama, with a model chosen per task. Receipts and scans are read with on-device OCR, and Whisper transcribes voice notes.

Can an automation change my data without asking?

Plain imports such as calendar and contact syncs apply directly. Anything that sends, moves or files, like reply drafts or the File Sorter, waits in a review queue until you apply it. Every run is logged.

What does the agent see?

The records and documents in your workbench, read on your Mac. Each answer lists the records it used, so you can open and check them.

Does this page use my data?

No. Everything on this page, including the working replica and the agent replays, uses the example data of a fictional consultancy, Hartmann AI Consulting. Nothing you click is sent anywhere.

Can I use it away from my desk?

Yes. The phone layout has card views for invoices, transactions, tasks and projects, and it is reached over your own network. A watch app for voice notes, a daily glance and quick approvals is coming soon.

The whole system

Run your business from one screen.

Every email, client, project, invoice and note of the example business, linked on one Mac. Watch one record lead to the next, or pick a page to open it in the workbench.
