### Distinct from the brief to the live campaign.

Your intent and your rules travel with the plan, all the way into flight.

### Every campaign adds context.

Each campaign files its brief, its decisions and its reported results into your history, so you and your authorized agents plan the next one with more to go on.

### 0% of media spend.

Semicola takes no share of your media. We earn from intelligence and completed work, never from a markup on your media.

## Work in Claude, ChatGPT or Semicola

_Your agent_

Start in an AI app you already use, work in Semicola directly, or connect your own agent over MCP or API. Every route reaches the same sellers.

- **Work in Claude or ChatGPT.** Connect Semicola once, then brief and buy from the chat your team already lives in.
- **Use the Semicola app.** Our own buying workspace, with no agent to build or host.
- **Bring your own agent.** Plug in an AdCP-compatible buying agent over MCP or API, and keep your own interface, logic and client experience.

## Send one brief to the sellers you choose

_Seller access_

Ask one seller or many. Every proposal comes back in the same shape, terms included, ready to compare.

- **Compare seller proposals.** Each proposal arrives in one structure, with the seller and its terms named, so you can line them up side by side.
- **Keep the proposal intact.** Turn the proposal you pick into a draft media buy with its seller, products and terms carried across, without asking the seller twice.

## You set the rules

_Your rules_

Semicola keeps the right brand, account and rules attached while your agent works. You decide what it may do on its own and what needs your sign-off.

- **Keep each advertiser separate.** Buying for several advertisers? Each keeps its own identity, connected accounts and activity trail.
- **Set the boundaries.** Fix budgets, exclusions and approval rules before a campaign goes live.
- **Approve what matters.** Your agent handles what it can. Anything outside the rules comes back to you.

## Compounding context

_Campaign history_

Semicola keeps each campaign’s brief, decisions and reported results. The record grows with every campaign, giving you and your authorized agents more to work from next time.

## See what your agent did — and what it suggests

_Your oversight_

Review the actions your agent took, what changed and what it recommends next. Every call and change made through Semicola is on the record.

## From brief to campaign.

Add the brand and the brief, ask sellers, run the campaign, and fold its results into the campaign record.

1. **Choose how to connect.** Start in Claude, ChatGPT or Semicola, or connect your own agent.
2. **Add the brand and brief.** Pick the advertiser and connected account, then write the brief.
3. **Ask sellers.** Your agent sends the brief to one seller or several and brings back their proposals.
4. **Review and run the campaign.** The proposal you choose becomes a draft media buy. Review where required, then launch.
5. **Add the results.** The campaign record holds the brief and the decisions. Reported results join it as they arrive.

## No cut of your media. Ever.

Connecting and placing buys is free. Optional intelligence is in beta, and its pricing is clear before you opt in. Enterprise support is priced with you. Whatever you choose, we take 0% of your media.
