THE PRODUCTION PROBLEM

A good idea gets lost
between the channels.

The LinkedIn post says one thing. The email says another. The carousel is still a blank slide.

Content Engine gives every asset the same source, message and next action. Start with an existing product brief, article, feature or research asset. Build structured drafts, refine them in one workspace, then take the finished files to the tools you already use.

Designed for solo founders, product marketers, independent consultants and small teams who handle their own content. Best when you understand the offer and need to produce the campaign.

You supply the judgment and final edits. The Studio uses writing frameworks. It does not run an AI model, retrieve URLs, create video footage, or publish to social accounts. Optional editing prompts work with an assistant of your choice.

EXAMPLE A / FICTIONAL SAAS

Tern Release Notes

The starting material: a manually maintained customer-facing release log for small SaaS teams.

The message: make the customer-facing change clear, then link to the useful next step.

The campaign: three LinkedIn posts, short social variations, a six-slide carousel, a 45-second video storyboard, three emails, newsletter feature, landing-page copy and 30-day schedule.

FICTIONAL TEACHING CAMPAIGN / TERN

The interactive preview uses the same interface and campaign files as the download. It is an inspection edition. Editing, backups and exports are included in the downloadable Studio.

FROM FIRST PASS TO PUBLISHABLE WORK

Make. Check. Keep.

01 / MAKE THE DRAFTS

Keep the message connected.

Choose your channels. Build starting assets from your structured brief. Edit every word. Paste source text for reference and use optional source-grounded editing prompts when helpful.

02 / CHECK THE CAMPAIGN

Review across the channels.

Check evidence, specificity, differentiation, permissions and the next action. The checklist records your review. It does not pretend to verify facts automatically.

03 / KEEP THE FILES

Export for the next step.

Markdown, TXT and portable HTML for copy. CSV for a dated 30-day publishing calendar. Editable SVG for carousel layouts. JSON for full-project backup and restore.

SVG exports are a vertical slide board with editable text, not a finished social PDF. Video output is a script and storyboard, not a rendered video. Your project stays in your browser unless you choose to copy or export it.

PRACTICAL ANSWERS

Before you decide.

Does this generate content with AI?

The Studio uses structured templates based on your fields. It does not run an AI model or automatically understand pasted documents. Optional prompts give an AI assistant your source and draft for editing. Nothing is sent automatically, and no paid API key is required.

Can I use it without your website?

Yes. The downloaded Studio is a single HTML application. Extract the ZIP and open it in a current desktop browser. The core workflow has no external scripts, fonts or network calls. Save JSON backups because browser storage can be cleared or unavailable for local files.

Will it fetch my product page or publish my posts?

No. URLs are saved as text references. Paste the source material you want to work from. Publishing, email sending, image rendering and video production happen in your own tools after review.

What can I export?

Campaign copy as Markdown, TXT and self-contained HTML; a 30-day calendar as CSV; a carousel layout as editable SVG; and the complete project as JSON. JSON is the supported restore format. No native video, PowerPoint, Canva or Notion exports are included.

Is this useful if I already own Launch to Market?

It may be, if you have made the launch decisions and now need to produce a deeper set of coordinated content. Launch to Market already includes starter campaign copy. Content Engine adds a dedicated production editor, previews, reusable channel resources, full campaigns and export workflow. Inspect the examples before deciding.

Can I buy it now?

Yes. Product Content Engine v1 costs $49 USD once, plus applicable tax. Review the worked examples and compatibility, then use secure checkout. After verified payment, download the ZIP and open START-HERE.html. Access instructions arrive by email; purchase recovery works with your checkout address.

Who makes it, and how do I get help?
