Each number comes from a walk you can read, step by step.

Jobs

New numbers in.
Your call on what stays.

A document can carry its own Jobs. They gather new figures, redraw the table and chart, and draft what changed. Then you keep or undo each part.

Research Brief

A small study. A clearer next question.

One primary need per person.

Approval records still lead this small, biased sample. The chart updates its numbers; the interpretation remains yours.

Your source stays beside the document.

Inspect the Jobs, then make one change.

Add interview I12, run Research Refresh, then open the changed table and chart.

Give a document a job. Flow runs it on your Mac, even overnight. Then you keep or undo each change.

Seven documents

Each one carries its own sources and Jobs. Open one, scroll it, and see what changes when new numbers arrive.

Make this document yours

The same three items appear as a table, a chart and a timeline. Change their names, dates and amounts in the profile, then keep the views that help you understand your own work.

  1. Duplicate this folder and name it for the thing it keeps current.
  2. Edit the profile and add files to entries/.
  3. Rename the headings and remove the blocks you do not need.

First item120Open
Second item80In progress
Third item200Done

Amount by item

First item 120, Second item 80, Third item 200. Group A contains the first two items; Group B the third.
One list powers the table and the chart.

One file for each entry

The profile holds the shared list; the entries folder holds the individual records. Each Markdown file contributes one row from its front matter, so a new entry can join the document without someone copying its values into another table.

The shipped folder begins with Example Entry, in group A, with a score of 72. Its updated date belongs to that record. Keep the fields that matter to your subject, and let the body of each entry carry the explanation behind them.

The shared profile starts with a subject and an owner, then three items with amounts, dates and states. A short table can show the owner and subject, while the item list supplies the more detailed views. This gives the document a place to say what it is about before asking a reader to interpret the individual records beneath it.

Dates and states have different jobs in the example. The first item is open, the second is in progress and the third is done. Their start and due dates provide the ends of a timeline; their amounts provide the bars. Keep those distinctions when adapting the folder, so a change to a deadline does not get confused with a change to the work itself.

  • Create one entry file per thing you want to track.
  • Keep the field names consistent across the entry files.
  • Use the folder inventory to see which files were added or changed.
  • Keep the subject and owner visible at the top of the profile.

Follow a number back to its source

Some views read the profile directly. Others read a dated capture written by Starter Refresh, the definition that names the source and the shape of the data. A binding with a star selects the newest capture by filename; the key after it selects a list inside that file.

The refresh changes the bound rows while the chart titles, table headings and surrounding prose remain yours. Keep the capture views if you need collected or computed figures. If the folder itself contains everything you need, the Starter explains which refresh and capture blocks you can remove.

The supplied calculation counts three items and two that are not done, adds their amounts to 400, and groups those amounts into A and B. The goal of 500 is a value written into the example. This is a useful distinction when reading the page. A measured total comes from the records, while the target expresses the comparison you chose to make.

The definition editor presents the sources, calculated values and output tables as a form, with the rows produced by each step alongside them. You can examine that sequence before changing it. The morning then has a clear record to report. It might be a profile edit, a new entry, a watched page’s changed text or a new capture. When nothing moved, the run remains in Receipts without a document change.

  • Describe your own source and required figures in Starter Refresh.
  • Choose the public pages you want watched and remove the example page.
  • Turn on Night Shift and inspect the first shift while it runs.

Questions

A few things
worth knowing.

Which Macs can run Flow?

macOS 26 or later, on Apple Silicon or Intel. Flow is distributed directly as a signed and notarized Mac app. Download availability follows the release cut. Read the technical requirements.

What stays when the 10 Pro Days are used up?

Base stays free forever for reading, writing, searching, organizing and charting Markdown, with Elements, Skills, the canvas and any Playbook you bring in from GitHub. Deterministic Living Document jobs and Morning Briefing are included. Model-powered Agency, Chat, definition drafting and Overnight notes need Pro, including when the model runs locally. Import and Publish are separate paid add-ons that need Pro; the 10 Pro Days include both.

What leaves my Mac?

Local model inference stays on your Mac. A configured cloud action sends selected content to the provider you chose. Named public-source jobs make network requests; optional public Web Lookups are separate and off by default. Flow 1.8 shares anonymized counts about how Flow itself was used — which features ran, which settings were on, and how long model work and review took — for one finished day at a time. It never includes your document text, your file names or anything that identifies your copy, and two switches in Settings ▸ Observations turn it off. Flow sends no automatic crash reports and needs no recurring online licence check to keep working. Help → Copy Diagnostics lets you inspect a summary before you choose to share it.

Can a team evaluate Flow?

Start with the same owned files, visible routes and inspectable changes. The enterprise page describes evaluation patterns, evidence requirements and rollout considerations. Read the enterprise guide.

Does Flow need to stay open?

No. Night Shift’s background helper can run with Flow quit. Your Mac needs to be available, plugged in and idle within your chosen window. If it misses a window, catch-up can run once after wake.

Does everything run locally?

Night Shift model work uses a local model. Jobs can read the public pages you name. During the day you can choose configured local or cloud model routes. Flow does not silently turn a local night into a cloud-model call.

Will it change my whole document?

You define the jobs and bindings. Night Shift updates declared parts, marks its changes and records receipts. Keep records your review; Revert restores the selected part. Your own later edits are protected from a blind rollback.

Product facts and press contact

Flow is a native Mac app from Orionfold LLC, built by Manav Sehgal in Silicon Valley, California. Its revision-scoped verifiable AI agency is patent pending. For product or press questions, contact [email protected]. Read the founder’s approval story.

Can I bring my own files?

Yes. Flow works with readable Markdown files and folders. Start with your documents or copy an included example, then adapt its sources and Jobs.

Bring your notes, sources and the work you do every month.
