Content Studio Kit
A studio for the part of posting that actually slows you down — deciding what to say, which hashtags to use, and what goes out when.
Less blank canvas.62 prompts
Keep the voice. Change the message.
The kit gives every new idea a strong starting point without making every post sound identical.
Caption generator
Describe the post and get a caption back. Works offline; add your own Anthropic key for live Claude output.
Three complete palettes
Pick a visual direction fast and copy the hex codes straight into whatever you design in.
Hashtag library
Multi-select the sets that fit and copy them in one click, per platform.
Content calendar
Plan the month so the posting decision is already made when the day arrives.
For creators tired of starting from zero.
- Your posting consistency changes depending on how busy the week is.
- You want a recognizable voice across several channels.
- You already have the visuals and get stuck on the words.
- You need structure without losing your own voice.
The blank posting box, solved.
The slow part of posting is rarely the posting. It is deciding what to say, which hashtags to attach, and what goes out when. Content Studio Kit is one file with five tabs aimed squarely at those three decisions, and it runs on your own machine with no account.
Caption generator
Describe the post, pick the platform — Instagram, TikTok, Pinterest, YouTube, LinkedIn, or X — then set your niche, one of eight tones, and a call to action. You get a caption plus hook variations to choose between.
Offline or live Claude
The generator works offline with no key. Add your own Anthropic API key and the same tab produces captions with live Claude instead.
62 caption prompts
A library of prompts across six themes for when you would rather start from a proven angle than a blank field.
Content calendar
A month grid, Sunday through Saturday, where each post idea carries a title and notes. What goes out when, visible in one glance.
Three brand palettes
Ready-made colour palettes with click-to-copy hex codes, so a post looks like it came from the same brand as the last one.
Hashtag library
Sets for Instagram, TikTok, Pinterest, and YouTube with multi-select and one-click copy. No more keeping a hashtag note in your phone.
Made for you if…
- You post regularly and lose the most time to the caption, not the content.
- You want hashtags and palettes to hand instead of scattered across notes apps.
- You want to plan a month of posts without another subscription.
- You would like AI captions that work offline, with your own key as an option.
- You publish to more than one platform and want the tone to change accordingly.
Probably not, if…
- You need to schedule and auto-publish posts; this plans them, it does not send them.
- You want analytics on how posts performed.
- You need several team members working in the same calendar.
- You want it synced across your phone and laptop.

Before you buy.
Does it publish or schedule my posts?
No. Content Studio Kit is a planning and writing studio — it produces the caption, the hashtags, and the calendar entry. Posting still happens in the app you already use.
Do I need an API key for the caption generator?
No. It works offline with no key at all. Adding your own Anthropic API key is optional and switches the same tab to live Claude for more varied captions.
If I add my key, where is it stored?
In your browser on your own computer, and it is used to call Anthropic directly. It never reaches a server of ours.
How many caption prompts are included?
62, organised across six themes, alongside the generator itself.
Which platforms are the hashtag sets for?
Instagram, TikTok, Pinterest, and YouTube, with multi-select and one-click copy.
Where is my content calendar saved?
In your browser's local storage under csk_posts, on the one machine where you opened the file. Clearing site data or using incognito will erase it, so keep the file somewhere permanent.
What if it is not right for me?
The refund policy covers where you stand, and the general FAQ handles download questions.
Open the studio with a head start.
Pick a prompt, grab your hashtags, and spend your energy on the idea instead.
