About
Software that extends
human expertise.
Digital Extensions is a software studio building tools for professionals who work directly with complex source material — and for developers navigating an AI-first world. We believe the best software makes an expert faster and more certain, without ever taking the judgment out of their hands.
Our Philosophy
The expert stays in control. The software keeps the receipts.
A lot of modern software is built to decide for you. That is exactly the wrong posture for work where the reasoning has to hold up — a legal chronology, an expert opinion, a graded assessment. When the stakes are real, you need to be able to point at where every conclusion came from.
So we build the opposite kind of tool: local-first, transparent, and honest about provenance. Your files stay yours. AI earns its place by extending your understanding — never by concluding on your behalf. Every output traces back to the source it came from.
Precision & Provenance
Every assertion traceable to its origin. Every annotation tied to its exact source location — because in this work, ambiguity carries real cost.
Local-First & Transparent
Your data stays on your machine. Original files remain pristine. AI runs locally when it can, and reaches the cloud only under a policy you set — no hidden inference, no conclusions drawn on your behalf.
Expert-Driven
Interpretation belongs to the expert. The software supports careful reasoning — it does not replace it, automate it, or quietly introduce assumptions.
Who's Behind It
Digital Extensions was founded by Kent Merrell, who builds the products and works directly with the professionals who use them. If you write in through the form below, you're reaching the person making the software — not a support queue.
