The problem

Marketing shouldn’t feel this difficult.

You have a business to run. The hours lost to “what should we post this week?” are hours your customers never see.

How it works

See a whole month come together

Tell it about your business once. From there it plans, drafts and schedules — you stay in the approval seat.

Plan

A full calendar, in one run

Describe your business and the month ahead — promotions, events, quiet weeks. Cstudio drafts a balanced calendar of posts, reels and stories that fits your actual plans, not a generic template.

Captions, images & carousels

Every slot gets a finished post: hook, caption, hashtags and visuals in your colors and voice. Carousels, single images or short-form video scripts — matched to what performs on each channel.

Publish

Approve, then publish

Skim the month, tap approve on what you like, edit what you don’t. Cstudio schedules everything at the best times and publishes without you touching another app.

Strategy, creation and publishing live in one place — nothing to stitch together.

01 — Plan
Strategy brief
A monthly content strategy grounded in your goals, seasonality and past performance.
Monthly calendar
Drag, swap and rebalance a full month of content on one board.
Campaign themes
Launches, promos and events become coordinated multi-post arcs.
02 — Create
Captions & hooks
Scroll-stopping first lines and captions in your voice, never boilerplate.
Images & carousels
Branded visuals generated in your palette — or built from your own photos.
Brand voice engine
A living profile of how you sound, refined every time you edit.
03 — Publish
One-tap approvals
Review the whole month in minutes; nothing goes out without you.
Best-time scheduling
Posts land when your audience is actually online, per channel.
Multi-channel publishing
Write once, publish natively to eight platforms.
Brand memory

AI that actually learns your business

Not generic captions with your name pasted in. Cstudio builds a living profile of your voice, offers, colors and customers — and every post draws from it.

The process

From blank month to published, in six steps

1
Tell it about your business
A 5-minute interview: what you sell, who buys, how you talk.
2
Review the strategy
Cstudio proposes themes and cadence for the month. Adjust anything.
3
Generate the month
Every slot fills with a designed, captioned, scheduled post.
4
Edit anything
Tweak by hand or just tell the chat what to change.
5
Approve
One pass, tap approve. Ten minutes for a whole month.
6
Publish & learn
It posts on schedule and folds results into next month’s plan.
Who it’s for

Made for businesses that market on the side

If marketing is the thing you do after the real work is done, Cstudio was built for you.

Restaurants & cafés
Specials, seasonal menus and the faces behind the counter.
Retail & e-commerce
New arrivals, restocks and promos that don’t feel like ads.
Wellness & studios
Class schedules, client wins and booking pushes on autopilot.
Trades & local services
Before-and-afters and seasonal reminders that win local trust.
Real estate & agents
Listings, market notes and neighborhood spotlights, consistently.
Consultants & founders
A steady expert presence on LinkedIn without living there.
Talk to your calendar

A chat box writes. Cstudio runs your calendar.

Ask for changes in plain language — swap a post, push a promo, change the tone — and watch the month reshuffle itself.

We’re launching the pumpkin menu on the 12th, not the 5th.
Done — moved the 3-post launch arc to Oct 12–14 and slotted a teaser on the 10th. Want me to shift the story polls too?
Yes, and make the teaser funnier.
Rewritten with a lighter hook. The updated week is in your approval queue — 4 posts, ready in one tap. ✓

Publish where your audience actually is

One calendar, formatted natively for every channel — sizes, captions and hashtags adjusted per platform.

Cstudio

A creative technology studio

Cstudio is built by Giant Peach — a small team of designers and engineers who believe good marketing shouldn’t require a marketing department. We ship weekly and read every piece of feedback.

Questions, answered

How does Cstudio learn my brand?
You answer a short onboarding interview and optionally connect your existing accounts. Cstudio builds a brand profile — voice, offers, colors, audience — that you can edit anytime, and every post is generated from it.
Do I have to approve every post?
By default, yes — nothing publishes without your sign-off. Once you trust the output, you can enable auto-publish for specific channels or content types.
Which platforms can it publish to?
Instagram, Facebook, LinkedIn, TikTok, X, Pinterest, YouTube Shorts and Google Business Profile, each formatted natively.
Can I edit the images and captions?
Everything is editable — swap images, rewrite captions, change dates. Or just tell the chat what to change and it will do it for you.
Is my data used to train models?
No. Your brand profile and content stay yours and are never used to train shared models.
