The Sintra Workflow
The SynthAI Workflow
SynthAI creates post, image, schedules, AND builds ad campaign
"Sintra has no API and no execution layer. It cannot automate steps 2–7. SynthAI was built to do all 7 — which is why it costs what it costs."
Sintra Gets More Expensive as You Grow. SynthAI Doesn't.
At 3 users, SynthAI saves approximately $2932/month in combined cost and time value.
Sintra: $97/user × 8 teammates = $776/month. For drafts. No API. No execution. No shared workspace. SynthAI Growth: $299/month, sized for teams of up to 8, no per-seat fees. Full execution. API included. Proactive AI.
Sintra is Latvian. SynthAI is Built for US B2B.

The One Feature That Doesn't Exist Anywhere Else
Every AI tool on the market — including Sintra — waits for you to ask.
SynthAI's Proactive Inbox prepares a personalized growth briefing for you every morning before you log in. Campaign ideas. Content drafts. Competitor alerts. Follow-up reminders. All ready. No prompting.
This feature has no equivalent in any AI tool at any price point. It cannot be replicated by Sintra without a complete architectural rebuild.
Not because we're better at AI. Because we built a different system.
The Feature Nobody Else Has— At Any Price
Every morning, your 10 AI specialists prepare a personalized growth briefing. Ideas. Drafts. Alerts. Actions. All tailored to YOUR business, ready before your first coffee.
Not Jasper. Not ChatGPT. Not Sintra AI. Nobody else does this.

Schedule This Week's Social Media Campaign
Engagement peaks on Tuesday and Thursday. Let me create and schedule 5 posts across all your platforms.
Why does this matter?
A tool that waits to be asked only helps on the days you already know what to ask for. The hard part of marketing isn't writing the post — it's deciding which post is worth writing this week. But proactive only works when it's tuned to YOU. That's why every suggestion has a feedback button. The more you use SynthAI, the better it understands what moves the needle for your specific business.
No other platform offers this. Not at $99/month. Not at $500/month.

From Sintra Users Who Switched
"I liked Sintra but I spent more time moving their drafts between tools than I saved. SynthAI just... does it. The campaign goes live. I don't touch anything else."
— Marcus T.
Marketing Agency Owner
"The per-seat pricing on Sintra was fine for me alone. The moment I brought on a second person it doubled. SynthAI is the same price for my whole team."
— Sarah K.
DTC Brand Founder
"Proactive Inbox is the thing. I open my laptop and my AI team already has 5 things ready. Sintra never did that. Nothing does that."
