Everything you can do with FridayOS

Welcome #

What FridayOS is, and how the pieces fit together.

Friday is the assistant you talk to. FridayOS is the whole system around it: a dashboard, an inbox, your calendar and tasks, your coding sessions, voice and phone calls, and a growing set of connected apps — all in one place, all reachable by just asking Friday in plain language.

The guiding idea is simple: you talk, Friday does the legwork, and nothing irreversible happens without your say-so. Friday reads freely, but every action that changes something — sending a message, editing a doc, scheduling a block — comes back to you as a one-tap proposal first.

Hosted or self-hosted

There are two ways to run FridayOS, and this handbook covers both:

• Hosted — sign up on the FridayOS site and get your own private instance in minutes. Voice, push, and calls are handled for you. Start free, no card required.
• Self-hosted Coming soon — run FridayOS on your own machine or server under the freeware license. You keep full control of your data; see Self-hosting.

Quick start #

From zero to a working assistant in about five minutes.

1. Request access. On the FridayOS site, request a spot (name, email, a short note). FridayOS onboards gradually during early access — once you're admitted we email you a persistent private instance at your own URL and your login. Nothing to install.
2. Sign in and set a password. The link in your welcome email opens sign-in with your email filled in — enter the one-time code we send. On first visit you set the one password that works across your dashboard, the mobile apps, and your account page.
3. Finish setup. Your account page shows two steps: connect your AI (one of the engines below — a quick, one-time sign-in) and add a calendar in indrajaal. Your apps unlock as soon as both are done, and the checklist ticks itself.
4. Say hello. Open the chat and ask Friday something real — "what's on my plate today?", "summarise my unread email". Watch it read your world and come back with proposals.
5. Make it yours. Ask it to reshape your dashboard or recolour the app (see Adaptation). This is the moment FridayOS stops feeling generic.

Choosing an AI engine

Friday is powered by your AI subscription — it never resells you tokens. Pick whichever you already pay for:

Switch engines any time from your account or by asking Friday. Your usage for the connected engine shows up as a live pill in the app, with a deep link to the provider's own dashboard.

Your account #

One login, one password, everything connected.

Your account page is the control room for the whole system. From it you can:

• Sign in with a real password — one credential works across all your FridayOS surfaces.
• Change your password centrally — update it once and it propagates everywhere.
• Connect your AI — link (or re-link) your Claude / Codex / Google engine. Connecting here propagates the credentials to the rest of your instance automatically.
• Manage your plan — see Plans & billing, or upgrade.
• See your usage and storage — memory, disk, and what's taking space, measured inside your instance, so it goes back down when you delete things.
• Sign in on your iPhone — scan the QR code for each app; the TestFlight install link sits under each code (see Mobile & widgets).
• Link a browser or a coding environment — see Files & browser and Coding sessions.

Put Friday on your tailnet Optional

If you use Tailscale, your instance can join your tailnet as one of your devices. Friday can then see which of your devices are online, drop files onto your phone or laptop with Taildrop, and you can open it at its private tailnet name. Make an auth key at login.tailscale.com/admin/settings/keys and paste it in Friday → Settings → Tailscale. Your account page shows whether it's connected. Nothing else depends on it.

Meet Friday #

How you actually work with the assistant day to day.

Chat & threads

The main way in is chat. Every conversation is a thread that persists across your devices — start something on your laptop, pick it up on your phone. Friday remembers what matters between sessions, so you rarely have to set the scene twice.

Mission Control

Your home screen is Mission Control — a live feed of cards that surface what needs your attention: tasks, calendar, inbox, coding sessions, code changes, and git activity. It's the "what's going on right now" view, and it's fully reorderable (see Adaptation).

Propose-then-approve

This is the heart of how Friday stays safe to trust. Reads happen freely; writes become proposals. When Friday wants to send an email, edit a Notion page, push a change, or schedule a block, it shows you exactly what it will do as an editable proposal. You approve, edit, or decline. Nothing outward-facing happens behind your back.

Autonomy tiers

As you build trust, you can loosen the leash per class of action. Each kind of action can be set to Auto (just do it), Ask (propose first — the default), or Never. Friday learns from what you routinely approve and can suggest promoting an action to Auto — but you're always in charge of the dial.

Projects #

Keep each project's context to itself — no setup, no modes, no picker to learn.

Every chat starts on your general memory — everything Friday knows about you. Any time, you can scope the conversation to a project just by asking:

From then on, that thread runs in the project's world. The project's own notes take precedence where they conflict with your general memory — but everything the project doesn't override still applies.

Adding project facts

You build a project's context the same way — by just saying it. Anything you tell Friday “for this project” is saved to the project and follows only its threads; nothing bleeds into the rest of your world.

The idea is that you never manage “project mode” — you promote a conversation by asking, keep giving Friday context in plain language, and each project stays cleanly separate from the others.

Browse your projects

When you want the bird's-eye view, the Projects tab lists your projects and everything filed under each — the threads you've scoped to them and the notes you've added. On web and mobile.

Voice & calls #

Talk to Friday hands-free — and let it call you when it matters.

Talking to Friday

Tap the mic and speak. Friday transcribes what you say, thinks, and replies out loud in a natural, conversational voice — times and lists are spoken cleanly, not read like markup. It's built for the car and the walk between meetings.

Fast Voice

Hosted instances get Fast Voice included: your speech is transcribed on dedicated fast-voice hardware, so it lands in a fraction of a second. There's nothing to switch on — every hosted plan comes with it.

Friday can call you

For something genuinely urgent — a failure that needs a decision now, an imminent deadline — Friday can ring your phone as a real incoming call, hands-free. You pick up and talk; the call becomes a normal thread. You decide what's call-worthy: tell Friday "call me for prod outages or flight changes, not routine stuff," and it remembers. Phone calls and push are part of the Push & Calls relay on hosted plans.

Proactivity #

Friday doesn't just wait to be asked.

The best assistant is one that notices things. FridayOS has a proactive layer that watches your world and reaches out when it's useful — never spammy, always something you'd actually want.

The morning brief

Start your day with a brief: today's schedule, what's due, anything that changed overnight, and a scan of your email. It's the first of the built-in flows.

When there's health data, the brief now opens with a quick body & energy read — and flags a real nutrition deficit or a muscle that's still sore — so the day gets planned around how you're actually doing. Only when there's something worth saying; no data, no noise.

Flows

Flows are Friday's proactive routines — scheduled or triggered prompts that run on their own. They live in Settings → Flows and are fully editable: change what the morning brief checks, add your own recurring nudges, or turn any off. No code, just plain-language prompts on a schedule.

Pings & initiative

Beyond schedules, Friday can notice a change to something you recently asked about and offer to help — the "prompt you didn't type." You'll see these on Mission Control and, if it's urgent, as a push or a call. Everything Friday raises this way is fresh and actionable, never stale.

Integrations #

Connect your tools by just asking.

Friday reaches your other apps through connectors. The magic is that you don't configure them by hand — you ask, and Friday walks the setup for you and starts pulling signals.

Say that, and Friday guides you through connecting the app, then starts working with its signals and can surface the updates you care about right on Mission Control. The same pattern works for a whole catalog of tools.

Bring your own tools

Beyond the built-in list, there's an integrations area (Settings → Integrations) for connecting other services yourself. Many developer tools support an open standard called MCP that Friday speaks — if a tool supports it, you can add it here and Friday can use it. This one's aimed at more technical users; most people never need it.

Tasks & calendars #

Your schedule and to-dos, understood — not just stored.

FridayOS includes a full tasks-and-calendar layer that Friday reads and reasons over. It understands how your projects and tasks depend on each other, so Friday can tell you not just what's due, but what's actually next and what's blocking what.

Calendars

Connect the calendars you already use — iCloud, Google, and Outlook — plus read-only calendar subscriptions. Friday sees a unified view of your time and can find real availability, propose blocks, and route scheduled work to the right calendar. All times show in your own timezone.

Tasks & reminders

Capture tasks with importance, deadlines, scheduling, recurrence, and steps. On iPhone, tasks sync two-way with Apple Reminders, so what you jot in Reminders shows up for Friday and vice-versa.

Health & Body Stack #

A health & fitness layer on top of Apple Health — so Friday plans around how your body is actually doing.

Body Stack reads the health data you already have and turns it into things Friday can reason over: how recovered you are, how much hard work today can take, where your nutrition is short, and which muscles still need rest. It lives in indrajaal (bundled in every Friday), on the iOS app and the web.

Where it shows up

On iOS and the web app there's a Health tab — a Volume / Recovery-map toggle plus your score, energy and nutrition cards. And Friday narrates it where it matters: in chat when you ask, and at the top of your morning brief when there's something worth knowing.

Coding sessions #

For the builders — Friday drives your coding agents.

If you use Claude Code sessions, FridayOS connects to them. Friday can search and pull your sessions, leave notes for them, and hand off build tasks with a full brief — decks, code, docs — then keep an eye on progress and report back.

Delegating work

Ask Friday to take on something buildable and it can spin up or drive a coding session toward a concrete goal, checking the output and steering — pausing to ask you whenever a real decision comes up. You approve the hand-off; Friday runs the loop.

Files & browser #

Give Friday things to read, and let it browse the web for you.

Attachments

Drop a file into chat — a PDF, a doc, an image — and Friday reads it. Documents are pulled in as text; images are shown to Friday directly. Ask it to summarise a paper, pull the numbers out of a report, or describe a screenshot.

Your workspace

Friday has its own private, secure workspace where it can save and read files — notes, drafts, downloads. It's a real, lasting file space that stays inside your instance, and Friday can hand a file straight to one of your devices when it's done.

The browser

Friday can read the live web, including pages behind a login. For sites that need you signed in — a university portal, a work dashboard — you log in once through a secure session and Friday reads them for you afterward. Every instance ships with a built-in browser for this, zero-config — and if you self-host you can point Friday at your own (see Bring your own browser below).

Bring your own browser Advanced

Friday drives a Chromium over CDP for all its web work — reading sites, the in-app live sign-in, and browser “hands” (click / type / fill forms). The built-in one is the default and needs no setup. If you self-host, you can swap in your own browser — for more resources, or to reuse a profile you’re already logged into.

Start Chromium with remote debugging and a persistent profile (so logins & 2FA survive restarts) — headless or headed, on any box your instance can reach:

chromium --remote-debugging-port=9222 \
  --remote-debugging-address=0.0.0.0 \
  --user-data-dir=~/friday-browser

Then in Friday: Settings → Browser → “Link your own browser (CDP URL)” (the browser_cdp_url setting) pointed at http://<that-box>:9222. It reroutes the whole browser integration — reading the web, the in-app sign-in screencast (the Browser tab), and click/type/forms. Clear the field to fall back to the built-in browser.

Adaptation & theming #

Reshape how FridayOS looks and behaves — just by asking. No settings maze, no code.

This is what makes your FridayOS yours. Everything below is driven by plain-language requests to Friday, and it sticks — your instance stays reshaped across every device.

Recolour the whole app

Ask Friday to change the look and it recolours the entire interface — background, panels, text, borders, and accent — coherently. You can set a single colour or paint a whole mood; Friday works out the matching shades.

Reshape your dashboard

Tell Friday which Mission Control cards matter and it pins, hides, and reorders them for you.

Density, theme, and tone

Go compact or comfortable, force light or dark, and shape how Friday talks — briefer or more detailed, calmer or more direct, more or less proactive.

Custom dashboards

Want a whole page of specific content — a focused view for a project, a morning cockpit? Ask for it and Friday builds you a custom dashboard, separate from the main Mission Control feed.

Let it learn

Opt in and Friday quietly adapts your dashboard over time to what you actually use — a gentle boost to the things you open most. It never overrides your explicit pins and hides, and you can turn it off any time.

Mobile & widgets #

FridayOS in your pocket.

FridayOS installs like a normal app on your phone and works even offline. On iPhone and iPad there are dedicated apps that plug deeper into the system.

Privacy & security #

Built so you can actually trust it with your life.

• Your instance is yours. Hosted instances are private to you. Self-hosted, your data never leaves your machine.
• Local-first data. Your tasks and calendar live in a local database and work fully offline; the core never phones home.
• Health data stays on your instance. Your phone reads Apple Health and sends it to your own server and Friday — Body Stack never routes it through us. Guidance, not medical advice.
• Propose-then-approve. Every outward or destructive action is confirmed by you first. Friday reads freely but never sends, posts, deletes, or pays on its own.
• Hard limits. Friday will not enter passwords or payment details, complete CAPTCHAs, or move money — it hands those back to you by design.
• Your own AI. Friday runs on your AI subscription and your connected accounts; there's no middleman reselling your data.
• Honest reporting. If something fails, you're told — no false "done."

Licensing

FridayOS is freeware: free to run on hardware you control, for personal or internal use. It is not open source — you may not redistribute, resell, or reverse-engineer it, or use it to build a competing service. The full terms ship with the software.

Plans & billing #

Start free. Upgrade when you're ready.

Manage everything — upgrade or downgrade — from your account page. Self-hosting FridayOS will be free under the freeware license, and is coming soon.

Self-hosting #

Run the whole thing on your own hardware.

Prefer to keep everything on your own box? FridayOS is becoming a free self-host bundle under the freeware license. Polymux is open and downloadable today; the full Friday + indrajaal app is coming soon — get notified from the self-host page. You bring your own AI subscription and your own hardware, and you get the same assistant with full control of your data.

Three ways to run it — and the trade-offs

FridayOS can run in a sealed space we manage, or on your own computer with as much access as you choose to give it. More access means more power and less separation — here's the plain version so you can pick what fits.

Connect it to your tailnet

FridayOS can join your Tailscale network, so your instance and your devices talk privately over the tailnet with nothing exposed to the public internet. Connect, check status, and disconnect from within the app.

What differs from hosted

• Voice runs on your own machine by default — it still works, just not the near-instant speed hosted plans get.
• Push & phone calls rely on the hosted relay, so those are a hosted-tier convenience.
• Everything else — the assistant, integrations, tasks/calendars, adaptation, the browser — is yours to run.

Troubleshooting & FAQ #

Quick answers to the things testers ask most.

Friday says no AI is connected

Head to your account page and connect an engine (Claude, Codex, or Google). Connecting there pushes the credentials across your whole instance. This is the single most common first-run snag.

The mobile app can't reach my instance

On the connect screen, enter your instance's full URL exactly. If you're self-hosting on a tailnet, make sure your phone is on the same tailnet and the instance is connected (see Self-hosting).

Voice feels slow

On hosted plans, Fast Voice is on by default — if it feels slow, it's worth flagging. On self-hosted setups voice runs on your own machine, so it's naturally a bit slower.

Friday didn't do something I asked

Check for a pending proposal — actions that change things wait for your approval. If you want a class of action to run automatically, tell Friday to stop asking about it (see autonomy tiers).

How do I give feedback?

Use the in-app feedback option, or email support (below). As a tester, your feedback directly shapes how FridayOS behaves — it's genuinely wanted.
