Transform messy text
into any format.
Build visual pipelines that turn dirty spreadsheets and documents into clean, structured output, and trace exactly which step did what.
How It Works
Four stages, one pipeline. Jump straight to any of them.

Hugging Face Build It Once. Share It With Everyone.
Design a flow in the visual builder, publish it, and anyone can run it as a one-click converter. No account needed.
What If Static Flows Fail?
Real data is unpredictable. The test adapter captures the breakage, and the AI assistant rewrites the pattern until the test passes again.

Watch a folder or run on a schedule. Every new file is transformed and delivered straight to your destination.
Built for Reliability at Scale
Every feature exists to make your text transformations traceable, testable, and production-ready
Process-Level Analyzability
Trace exactly which node in your chain transforms A into B. Every step shows its input, output, and logic, making continuous improvement intuitive, not guesswork.
Batch Folder Processing
Apply your flow to an entire folder of text files at once. All processed results are neatly organized into an output folder. No more one-file-at-a-time copy-paste.
Triple-Mode Builder
Switch between three views of the same flow: a visual graph builder, a linear step builder, and a purpose-built text DSL. The DSL is faster and AI-friendly, while every mode keeps full analyzability. Highlight any section to see its process-level data autopsy.
AI as Supervisor, Not Performer
Give AI an origin and destination sample and it builds the flow, then verifies it with TDD, testing that the output actually matches your expected result. Or prompt it for a single tricky pattern and keep the logic yours. Reliable transformations without trusting AI to do the work directly.

Frequently Asked Questions
Everything you need to know before you start building.
What is CubeChains?
A visual flow builder that turns messy, semi-structured content - spreadsheets, exported docs, pasted text - into clean, import-ready formats like Moodle XML, Aiken, and GIFT. You build a transformation pipeline by dragging and connecting nodes.
Do I need to know regex or code?
No. You build flows by dragging nodes onto a canvas, and shared flows run with a single click. Regex is there when you want fine-grained control, but it is never required to use a flow someone else built.
Is my data private?
Yes. Flows execute entirely in your browser - your content is not uploaded to a server to be processed. That privacy model is the same whether you build a flow or run a shared one.
What output formats can I create?
Virtually any text-based format. Because flows are regex-based, you can shape output to almost any structure you need - there is no fixed list. Quiz and question formats for learning platforms (Moodle XML, Aiken, GIFT, QTI) and general formats like CSV, JSON, or custom markup are just common examples, not limits.
Can it handle images?
Yes. Image handling is built in, so questions and content keep their figures instead of being stripped - something most conversion tools cannot do. Image support is still an experimental feature, so expect rough edges as we refine it. Image handling is available on every plan.
Can I share a flow with my team?
Yes. Publish a flow to a link and others can run it one-click on their own data, with no account setup or knowledge of the internals. Power users can fork a shared flow and tweak it for their own format variations.
