Why we build our own tools: VoxCut & InOneShot
Why does an agency build its own tools?
La Fabrik Numérique doesn't only build sites and software for clients. Part of the studio's time also goes into solving its own recurring pains — repetitive tasks, tools that don't exist yet, or exist but poorly.
Two pieces of software came out of that: VoxCut and InOneShot. Both published on the Microsoft Store, both born from a real, concrete need rather than a market idea.
How does VoxCut automatically remove silences?
While editing podcasts and interviews, the same chore kept coming back: spotting silences in the timeline and cutting them out by hand, minute after minute.
VoxCut automatically detects and removes silences from an audio or video file — 100% local, files never leave the machine. It exports directly to XML/EDL for Premiere Pro and DaVinci Resolve, processes files in batch, and handles files up to 5 GB without flinching.
The result: an edit that used to take an hour of manual cutting now takes a few minutes.
How do you generate personalized PDFs without a Word masterclass?
Another classic chore: generating dozens of personalized documents (certificates, contracts, invitations) from a PDF template and an Excel spreadsheet.
InOneShot works by drag-and-drop: you place fields — columns, dates, signatures, QR codes — directly on the PDF preview, then the app generates every filled document in one go.
Hundreds of personalized PDFs, one click, straight from a spreadsheet.
What's the link between internal tools and client projects?
Building your own tools takes the same discipline as building a client's: understand the real problem, keep only what earns its place, and ship something that still runs a year later with no hidden debt.
If you have a repetitive task in your business that deserves the same treatment — a tool built for exactly your workflow instead of a generic app bent out of shape to fit it — that's exactly the kind of project the studio likes to take on.

Building your own tools quickly raises questions of method. We detailed how to automate a small business's repetitive tasks with AI, and what VoxCut taught us about why a SaaS can have users but no sales. A concrete example: automatically removing silences from a podcast.
