SAI does the work.

Not a chatbot. An autonomous colleague that summarizes, drafts, plans and reports across your whole agency.

Every brand, remembered.

A living dossier of voice, taste, decisions and every "no".

Bill the world.

B2B invoices in any currency, export-exempt VAT and proformas, automatically.

The night shift.

Sunday, 8 pm. Your agency reports to you.

Your brand, your domain.

SAI

SAI lives on every page of SmoothOS. It knows the record on your screen, works with your permissions and always answers in your language. Five specialist agents, operator, finance, delivery, brand and growth, share one memory of your agency.

01

Ask anything

Press Cmd+J anywhere. Ask "Which retainers will run over this month?" SAI reads your data, not the internet, and tells you which agent answered.

02

After every meeting

SAI reads the transcript and writes the summary, the decisions and a draft task list. Approve them in one click. Decisions flow into the brand's memory.

03

The night shift

Every Sunday at 8 pm, SAI reads the whole agency: hours against budget, overdue work, money collected and late, drafts waiting for you. On Monday you walk in knowing what matters.

Every SAI call is logged with who asked and what it cost.

INSTITUTIONAL MEMORY

Every client gets a living dossier that grows with every meeting, file and revision: their voice, their taste, their decisions, and every "no". A new designer knows the client on day one. SAI follows the dossier in everything it drafts.
Too little to go on? SAI says so. It needs 3 analyzed meetings or 2 finished projects before it judges a brand.
How the dossier works
GLOBAL FINANCE

SmoothOS decides the VAT treatment of every invoice on its own: standard at home, export-exempt for businesses abroad, none where it doesn't apply. Foreign-currency invoices lock the official rate on the day they're issued. Proformas and receipts draw themselves, in English or Turkish.
  • Drafts, partial payments, overdue tracking
  • Proposals that become the project's scope
  • Retainers with rollover and overage
  • Time that turns into invoices
SmoothOS calculates and documents. Your accountant stays in charge.

CLIENT PORTAL

Clients follow projects, approve work, see invoices and their retainer balance under your name and your domain. Their revisions go straight into the brand's dossier.
Explore the client portal
SCOPE SHIELD

When a client asks for something outside the signed proposal, SAI flags it with the quote and the speaker, and offers a draft invoice. The amount is calculated by code. Your client sees nothing until you approve.
57% of agencies lose $1,000 to $5,000 a month to unbilled scope creep. (The Drum, May 2025)

We ran our studio on five tools that never spoke to each other. Tasks in one place, money in another, the client's taste in someone's head. So we built one system, and an intelligence to run it. Now we're opening it to 100 founding agencies.
Salih Durak, Founder

SmoothOS is agency management software: projects and tasks, time and retainers, proposals and invoices, a client portal with your logo and colours, and a memory of every client, in one web app. Its AI assistant, SAI, answers from your agency's own data with each person's permissions. Plans start at $49 a month.

Yes, for scheduling and time: Google Meet and Zoom connect to SmoothOS, and client calls book on your own page. Meeting analysis runs on speaker-labeled transcripts today; the recording bot that joins your calls is coming soon.

SmoothOS trains no models. SAI sends a request to an AI provider only when someone asks or a scheduled job runs, with only what that person can see. The provider's own terms apply; with your own key, the terms of your account.

No. Bring one project's export over first and keep ClickUp or Asana running beside it. Every import can be undone in one click.

A full data export ships before general launch. After a subscription ends, your agency and its files are permanently deleted after 60 days.
