Automate the generation of documents from a universal templating engine. Create templates with your favourite text editor, and add dynamic content with Carbone tags (text, colours, images, graphs). Anybody can design beautiful documents, not only developers.

Carbone Skill for AI
Launching today
Carbone is a universal document-generation engine: feed it a template file and JSON file, and it produces pixel-perfect documents at scale. The Carbone Skill teaches AI assistants like Claude or ChatGPT the entire Carbone templating language. Describe what you want in plain language and your AI writes correct Carbone syntax, builds templates in DOCX, XLSX, PPTX, HTML or PDF, and validates tags before you render automatically at scale.

@steevep Congrats on the launch team. Very cool, can I upload brand CI etc and have it extract the details and apply to new docs?
Carbone
Bonjour @zolani_matebese 👋
The Skill itself teaches the AI the Carbone templating language rather than doing brand extraction directly, but in practice, yes, you can absolutely achieve this.
You can give the AI your brand details (colors, fonts, logo) as context, paste your guidelines, a hex palette, or even an existing PDF brand document, and ask it to build templates that match. It'll apply your styling to the generated DOCX/XLSX/PPTX/HTML templates. If you have a structured brand kit, the cleaner the input, the more consistent the output.
Happy to walk through an example if you'd like, I'm available for a demo!
Document templates as a skill layer for AI is a powerful pattern — especially for structured financial documents where the same template logic needs to run across hundreds of variations.
I publish project finance and valuation model templates on Eloquens (eloquens.com/channel/samir-asadov-cfa) and the templates are Excel-heavy with formula interdependencies that go beyond text placeholders. The XLSX support in Carbone is what makes this interesting — does the AI understand Excel formula syntax and named ranges, or is it treating the .xlsx primarily as a tabular structure to fill rather than a live calculation engine?
Carbone
Thanks @samir_asadov ! you're asking exactly the right question.
Good news for your use case: Carbone keeps the XLSX as a real, working workbook. The formulas, the inter-dependencies, the named ranges you've built in Excel: they all stay intact. Carbone just drops the dynamic data into the cells your formulas point to, and everything recalculates normally when the file opens. So your model stays a model, and it's not getting flattened into static numbers.
The Skill's role is teaching the AI to place Carbone tags correctly within that structure, including inside formula contexts and across ranges without breaking the formula references.
If you'd like to stress-test it against one of your valuation models, happy to help you try it. I'm available for a live demo :)
great work! How does the validator catch a formatter that doesn't exist in Carbone? I am thinking if the AI invents a name that's syntactically clean but unknown, is the skill parsing against an actual grammar pre-render?
Carbone
Merci @artstavenka1! To answer your question: The Skill is a knowledge layer that grounds the AI in Carbone's complete documented formatter set, with a core rule: "never invent syntax, anything not documented doesn't exist." So a clean-looking but unknown formatter gets flagged against the real reference list instead of accepted. The actual grammar enforcement happens at render time in Carbone's engine; the Skill's job is to catch the invented ones before you get there.

Love the practical approach here. Teaching AI the actual templating language, rather than relying on guesswork, feels much more reliable for production workflows.
Carbone
Merci @marianna_tymchuk!! That's exactly the thinking, without the Skill, AI tends to invent syntax, or borrow it from other templating libraries or programming language, so you get tags that look plausible but the syntax is not supported and rejected by Carbone. The Skill grounds it in Carbone's real documentation, plus production template examples, patterns and logic: so you get correct, elegant tags every time ✅.

Hey Product Hunt! 👋
Carbone was born from a simple frustration: why do developers have to get involved every time a business needs to tweak a document? An invoice layout, a new field on a contract, a translated report — small changes that would eat up hours of dev time.
So we built Carbone around one idea: anyone should be able to design and own their document templates. No code required. Just open Word, Excel, or LibreOffice, drop in some tags, and the engine handles the rest. Business teams got their autonomy back. Developers got their afternoons back.
That was already a big step. But there was still a learning curve — the templating syntax, the JSON structure, the API calls. Nothing insurmountable, but still a door that not everyone would push open.
Today, that door is wide open.
With our new AI Skill, you don't need to know Carbone's syntax. You don't need to think about JSON. You just describe what you want — and the AI figures out the rest, feeds Carbone, and hands you back a polished document in seconds.
From "no code required" to "no friction at all". That's the journey we've been on since day one.
We can't wait to see what you build with it. 🚀🇫🇷
Very interesting launch. How well does the Skill handle large multi-page reports with nested loops and conditional sections?

Can it handle complex tables and conditional sections in DOCX without breaking formatting when data varies a lot?
