AI for agencies that absorbs the work between client and contract
Drafts campaign briefs, decks, copy, and weekly status updates across every active client.
Pulls performance from every channel into one client-ready report. Brain AI keeps the voice consistent.
Plugs into Slack, Notion, Google Drive, and your project tool so the work happens where the team already lives.
Every agency workflow in one platform
Agency work runs across briefs, decks, copy, performance reports, and the inbox between you and the client. Sintra runs those layers for you. Twelve specialised functions for content, performance, account management, and pitches, all sharing each client's brand context through Brain AI.
What slows down an agency
AI agency work should mean more billable hours and fewer admin ones. These are the drains every studio runs into.
Client status reports eat Mondays
Pulling progress across five clients, four channels each, into a deck before the 9 a.m. call is the work that ate Sunday.
Scope creep is undocumented
The brief said three social posts. By week two it's seven, plus a landing page. Nobody flagged it because everyone's working.
Deliverable voice drifts
Three creatives wrote for one client this month. The brand voice came through different on each. The client noticed.
Pitch volume sits below capacity
You could pitch ten new accounts this quarter. The decks take a week each, so you pitched two.
Onboarding takes a week per client
The kickoff doc, the brand voice notes, the channel access, the first deliverable draft. Each one is a day. Each one slips.
Junior work needs a senior review
You're not paying senior rates to copy-edit junior drafts. But the drafts come back needing it, every time.
How AI for agencies runs your delivery, function by function
Each role is built for one part of the work. Brain AI holds each client's brand voice, briefs, and past best-performers.

How agencies actually use AI for agencies work
Five workflows that recover the billable hours.
Client kickoff
Drop the new client's brand assets, brief, and competitor list into Brain AI. AI builds the kickoff doc, the channel-by-channel strategy outline, the first month's content calendar, and the welcome deck. A week of onboarding done in a morning.
Weekly client reports
AI pulls each client's channel performance, drafts the narrative, and builds the deck. Monday's standup starts with finished work, not Sunday's drafting.
Pitch sprint
Drop the prospect's site and the RFP into Brain AI. AI drafts the strategy outline, the case-study angle, the team page, and the deck structure. Pitches you wouldn't have written get written.
Deliverable QA
AI runs every draft against the client's voice notes in Brain AI and flags inconsistencies before they hit the senior review. Junior output ships with one round of edits, not three.
Scope tracking
AI logs every deliverable against the signed scope, flags creep early, and drafts the upsell email when the scope has genuinely grown.
Twelve AI tools for agencies, one subscription
Each role is built for one part of agency work. They share each client's voice and past best-performers through Brain AI.
Brain AI keeps each client on-brand
Drop each client's brand guidelines, past deliverables, brief notes, and voice samples into Brain AI. The system holds up to five separate brand profiles, so the social post for client A doesn't sound like the email for client B. 93% of users see response accuracy improve once Brain AI is populated.
