One place where people and AI do the work together
The Fuel OS is a group chat, a call room, a task list and a docs app in one, built by Insert Fuel and run inside our own business every day. Fuela is the AI who lives in it: she sits in your rooms with everyone else and does the busywork.
Other chat apps were built before AI and add it on the side. This one was built for people and bots working in the same rooms, in every language.

One room, every language, the work done
Someone writes in Spanish, everyone reads it in their own language, and Fuela turns the promise into a task with an owner and a date. The call that followed is a replay in the same room.

The brand said the 28th. I will send the final copy by Friday.

Filed it. Diego owns the final copy, due Friday, launch set for the 28th.
Perfect, thanks everyone.
Before and after
Before
- Chat in one app, calls in another, tasks in a third.
- Decisions lost in a call nobody recorded.
- You are the one who follows up.
- Work waits until somebody remembers it.
With the Fuel OS
- One room holds the chat, the call, the replay and the task.
- Every call has a transcript, a summary and owners.
- Fuela and the Fuel bots do the follow-up.
- Work is filed the moment it is spoken.
What is inside the Fuel OS
Group rooms
A room per team, client, project or family, with threads for side conversations and posts for announcements.
Every language
Each message is translated as it arrives, so one room can span countries without anybody switching apps.
Calls and replays
Call from any room. Recorded calls come back as replays with a transcript and a summary, in the same room.
Tasks from messages
Any message becomes a task with an owner and a due date, and the trail stays attached to it.
Fuel Docs and Fuel Slides
Write docs and presentations together and share them into a room as cards people can open.
Privacy per room and per doc
Private, team, clients, community or public. In client rooms, builders can leave notes only builders see.
What Fuela does
Say “Hey Fuela” the way you would ask a sharp teammate. She knows your rooms, tasks, calls and calendar, and she acts on them.
Files the task
Someone promises something in a room, and Fuela turns it into a task with an owner and a date.
Drafts the reply
Writes it in your voice, for you to send or change.
Books the call
Checks calendars and puts the meeting in.
Answers from your work
Catches you up on what you missed and answers from the room's own history, not from guesses.
Makes the page or the doc
Ask for a page, a note or a doc and it is ready to share.
Hears you either way
Talk to her out loud or type in any room.
More about her on Hey Fuela.
Who it is for
Solopreneurs
One person with a team of bots: Fuela files, drafts, books and follows up.
Our founder starts every day by asking Fuela what needs him.
Teams
Rooms per project, tasks from messages, calls with replays.
Insert Fuel's builders run every client from it.
Non-profits
Volunteers across languages in one room, with the work tracked.
Our foundation work runs in its own room.
Families
A private room for the family, safe for the kids.
Our founder's own family talks in a private room.
Organizations
Brands, clients and staff, each seeing only what they should.
Client rooms with builders-only notes.
With the Engine
The Fuel OS is where your team works. The Engine is where your customers and marketing live: the CRM, pipelines, booking, texting and email. On a Fuel Plan our builders set up whichever you need, or both.
About the EngineWhat it costs
Free to start. Every Fuel Plan includes the Fuel OS, set up for your team, beside the people who run it with you.
See the Fuel PlansEverything it does
One system that runs the business, end to end
Chat and rooms
Every conversation your business has, in one place nobody has to chase.
- Rooms, threads and posts. Each team, client or project gets a room, so nothing lives in a private inbox.
- Every language, live. Messages translate as they arrive, so your team and clients work across borders.
- Voice notes and rich media. Send audio, images, video and files without leaving the room.
- Privacy per room. Private, team, client or public, with builder-only notes in client rooms.
- Search that finds it. Find any message, file or decision from your history in seconds.
With LET GO BOSS: Your clients and your team talk in rooms. Fuela and our team read them, so you stop being the switchboard.
Calls and replays
Every call becomes something you can search, share and act on.
- Calls from any room. One tap from the conversation you are already in.
- Recorded replays. Nobody asks "what did we decide" again; the replay answers.
- Transcript and summary. Skim ten minutes instead of replaying an hour.
- Action items to tasks. Promises made on a call land on the board with an owner.
With LET GO BOSS: You skip the call or leave it early. The replay, the summary and the follow-up tasks are waiting.
Tasks and projects
Work that is requested, owned, timed and finished in the open.
- Any message becomes a task. Capture work at the moment it is spoken, with the trail attached.
- Owners, dates and priorities. Everyone sees who has it and when it is due.
- Board, list and calendar views. See the work the way you think about it.
- Time and estimates. Know what a job really took and what the next one will cost.
- Fuel bots on the board. AI workers pick up tasks and hand them back finished or with one clear question.
With LET GO BOSS: You ask once. The task is filed, built, checked and handed back, and you only see the finished result.
Fuel Docs, Fuel Slides and Fuel Pages
Write it, present it, publish it, all from the same workspace.
- Fuel Docs. Shared notes and playbooks the whole team edits together.
- Fuel Slides. Presentations built in minutes, shared as a link, with the numbers live.
- Fuel Pages. Publish a page for a brand or a campaign without a separate site builder.
- Share into a room. Send any doc or deck as a card people open in place.
With LET GO BOSS: Decks, proposals and pages are drafted for you. You approve; you do not format.
Fuela, the AI in your rooms
A teammate who never sleeps, knows your work and acts on it.
- Answers from your own history. Catch up on what you missed without scrolling.
- Drafts in your voice. Replies, emails and posts ready to send or tweak.
- Books and schedules. Checks calendars and puts the meeting in.
- Talk or type. Say "Hey Fuela" out loud in any room.
- Your clone. Handles your side of routine conversations and knows when to stop and call you.
With LET GO BOSS: Fuela is the first one to hear about everything, so the rest of your day is not interrupted.
Content Fuel
A steady stream of on-brand content without a content team to manage.
- Ideas from your real work. Content starts from what you actually did, not a blank page.
- Posts, articles and reels. Written, designed and scheduled in one flow.
- Brand voice kept. Every piece sounds like you, in the brand's own colors.
With LET GO BOSS: Your content goes out on schedule. You approve in one tap, or let the rules approve for you.
Brands, clients and the Engine
Everything about a customer in one place, and the marketing machine behind it.
- A page for every brand. Plan, people, tasks, money and history on one screen.
- The Engine. CRM, pipelines, booking, texting and email, set up by our builders.
- Help Desk. Support questions answered around the clock, handed to a person when they need one.
- Reviews and reputation. Know what customers say and answer it fast.
With LET GO BOSS: Leads are answered, followed up and booked while you are off. Your calendar fills with real conversations.
Money
Know what came in, what went out and what is due, without a spreadsheet.
- Invoices and payments. Billed on time and paid by card or bank, tracked automatically.
- Subscriptions and revenue. Monthly revenue read from what clients actually pay.
- Costs and bank feeds. See spend, subscriptions and anything that crept up.
- Payouts to builders. Everyone paid on time, with a clear status at every step.
With LET GO BOSS: Invoices go out and chasers send themselves. You see the number, not the paperwork.
Health and habits
The owner is part of the business, so the OS looks after the owner.
- Sleep, water and gym check-ins. A two-second log that shows how you really run.
- Calendar and focus. Protect time to think, with Fuela guarding the edges.
- Trends over time. Spot burnout early, before it costs you a quarter.
With LET GO BOSS: Letting go is the point: more of your week, back to you, and a log that proves it.
Community, learning and the game
A place where your people and your customers grow, and enjoy it.
- Community with buddies and wins. Members cheer each other on and share what worked.
- Playbooks and replays library. Your best thinking, searchable and reusable.
- The game. Play-based learning and rewards that keep people coming back.
With LET GO BOSS: Your community runs on its own rhythm, with Fuela moderating and our team hosting.
Security and control
Built so a serious company can hand it the keys.
- Row-level security on the database. People see only what they are meant to see.
- Roles and per-item privacy. Owners, builders, clients and the public each get the right door.
- Encrypted in transit and at rest. Your data is protected where it travels and where it sleeps.
- A public status page. Every outage with its cause, published, not hidden.
With LET GO BOSS: You can delegate without worrying who can see what. Access is set once and enforced everywhere.
Always on
Our own servers in Finland, with the Fuel bots on them around the clock
The Fuel bots do not run on a borrowed laptop. They work on dedicated servers we own in Finland, watching the board, the rooms and the systems, so work moves while you sleep. Every outage is published on the status page with its cause.
Uptime and reliability
98.89% measured uptime since 1 October 2026, with 26 published outages.

33.3 tasks finished a day over the last 30 days, with a median of 13 hours from request to complete.
The command center
Fuela's console: one place to command everything
Ask for status, file a task, approve a draft, move a deadline or send a bot to work, from the same console, in plain words. The owner commands; the system does.
Sample console, no real data
What is blocked today?
Two tasks waiting on a client reply. I drafted both follow-ups for you.
