Your AI-Human Virtual Assistant that can do anything.

One assistant that works at machine speed and checks its work with human judgment. Hand it your inbox, calendar, research, admin, or any task you can do on a computer, and get it back done.

Every task is checked by a person before it reaches you.

Example task
Triage my inbox and move Thursday's client call.
The AI sideSorts the inbox, drafts replies, finds three open meeting times.
The human sideChecks every draft, handles the sensitive ones, and confirms with you.

One assistant, two kinds of intelligence.

Hiring an assistant is slow and expensive. AI tools are fast but need constant babysitting, and they get things wrong without telling you. Tandem is neither a person with tools nor a bot with a supervisor. It's a single assistant built from both: AI that works around the clock and in parallel, and human judgment that checks, decides and takes responsibility. You talk to one assistant and get one finished result.

How it works

From first call to your first finished task in about three business days.

1. Tell us what to take on

A 20-minute call to map your recurring tasks, tools and preferences.

2. We set up your tandem

Your assistant is set up with your tools, accounts and preferences.

3. It does the work, then checks it

The AI drafts, researches, schedules and chases. A person reviews every output before you see it.

4. You approve and improve

Approve in one click. Each correction teaches the system your style.

Four ways to get started

Start light and go deeper when you're comfortable. You choose how much access we get, and you can change it any time.

1

Just send it

Email or forward tasks to your Tandem address, or message us. We never touch your accounts.

Best for: research, documents, one-off jobs.

2

Share only what's needed

Share a calendar, a folder or a task board with us. We see those and nothing else.

Best for: scheduling, files, recurring admin.

3

Delegate your inbox

You give us delegate access to read, draft and send on your behalf. No password is ever shared, and you can remove access in one click.

Best for: busy founders and executives.

4

A mailbox just for us

Your IT team creates an address like assistant@yourcompany.com with only the access we need.

Best for: companies and teams.

You decide how much we can do

Pick an approval level for each kind of task. If you don't choose, we use the safest one.

Draft only

We prepare everything and you send it yourself.

Default

Send after approval

Anything that leaves your account, such as emails, payments and posts, waits for your OK.

Send automatically

Only for routine things you've pre-approved, like confirming a meeting.

Our promises on access

  • We never ask for your passwords.
  • Every account we use has two-step verification.
  • We access only what a task needs.
  • Your information is kept separate from other clients'.

About Tandem

Tandem exists because good work needs both speed and care. Our assistant combines autonomous AI with human judgment, so the busywork gets done fast and a person makes sure it's right.

Questions people ask

Is it AI or a person?

Both, working as one assistant. The AI does the first pass and a person reviews it and talks to you.

Can it really do anything?

Anything you can do on a computer or by phone, in practice. A few things we won't take on, like anything illegal or work that needs a licensed professional. We'll tell you plainly before we start.

Can the AI send things without my approval?

Only if you allow it. By default, anything external (emails, payments, posts) waits for human review and your approval rules.

How is my data protected?

We use scoped access, encryption, audit logs and signed confidentiality agreements. You can revoke access at any time.

What counts as an hour?

An hour is time a person spends on your tasks. The AI work that goes with those tasks is included and isn't billed separately. We keep a log of every task and the time it took, and share it with you each month.

What if I need more hours than my plan?

Extra hours are $15 each. We never go over your plan without asking you first, so there are no surprise charges. If you regularly need more, we'll suggest a bigger plan.

Do unused hours roll over?

No. Hours reset each month, and you can change or pause your plan monthly.

Do you need my passwords?

No, never. We use delegate access, shared calendars and folders, or an address your IT team creates for us. You can remove access at any time.

Can you send emails as me?

We can send on your behalf once you've given us delegate access, and by default we wait for your approval first. If you prefer, we write from our own address and sign as your assistant.

Can I reach you on WhatsApp?

Yes. Message us on WhatsApp at +880 1886 833019 for quick questions or to send a task.

Which tools do you work with?

Gmail, Outlook, Google Workspace, Microsoft 365, Slack, Notion, HubSpot, Salesforce, Calendly, Zoom and more.

How fast can we start?

Most clients are live within 3 business days of the intro call.

What if I'm not happy?

Tell us. We rework the task at no cost, and you can cancel monthly plans any time.
