Writer RAG tool: build production-ready RAG apps in minutes

RAG in just a few lines of code? We’ve launched a predefined RAG tool on our developer platform, making it easy to bring your data into a Knowledge Graph and interact with it with AI. With a single API call, writer LLMs will intelligently call the RAG tool to chat with your data.

Integrated into Writer’s full-stack platform, it eliminates the need for complex vendor RAG setups, making it quick to build scalable, highly accurate AI workflows just by passing a graph ID of your data as a parameter to your RAG tool.

Imagine a world where doctors don’t guess anymore. A world where surgeries, medications, and treatments are tailored to your unique body, tested in a virtual environment before ever being applied to you. This isn’t science fiction—it’s the revolution AI is driving in biology, medicine, and beyond.

At the forefront of this transformation is the Virtual Twin: a digital replica of your body that incorporates every detail about your organs, medical history, and even how your body responds to medications. This technology, much like how engineers simulate jet engines or cars, is now being used to model the human heart, brain, and beyond—bringing a new level of precision to healthcare.

From Rare Diseases to Groundbreaking Solutions
The story begins with Steve Levine, whose daughter Jesse was born with a rare congenital heart defect. Doctors had limited data to rely on, making treatment incredibly challenging. But Steve's background in simulation technology gave him a revolutionary idea: what if we could create a 3D digital model of the heart to test treatments safely?

Thus, the Living Heart Project was born, and within a year, it was fully operational. It has since opened doors to treating pediatric cases, where clinical research is often too risky or scarce. For children with rare diseases, this technology eliminates the danger of trial and error, allowing doctors to simulate thousands of scenarios to find the best course of action.

And the impact doesn’t stop there. When Steve faced a life-threatening brain tumor, the same virtual twin technology enabled his surgeons to plan the operation with unparalleled precision, preserving delicate nerves and removing the tumor completely.

The New Industrial Revolution—For the Human Body
We’re on the cusp of an industrial revolution for biology. Just as engineers build virtual models to test airplanes or buildings, healthcare can now leverage AI to test “crazy ideas” on virtual twins. By the time treatment reaches a patient, there’s no guesswork—it’s right the first time.

From Personalized Medicine to Digital Immortality
As AI continues to evolve, its potential stretches beyond healthcare into something more profound: digital immortality. By gathering every bit of data about your life—your conversations, decisions, and behaviors—AI can create a digital version of you, called a chronicle, that could live on after you’re gone.

Imagine being able to talk to a digital version of a loved one who has passed, hearing their advice, or even seeing the world through their eyes. While this idea straddles the line between comforting and eerie, it opens up new possibilities for storytelling, legacy, and connection.

But it also raises big questions:

• Who owns this digital identity?

• What safeguards are in place to prevent misuse?

• Can AI truly replicate the complexity of being human?

The Next Frontier: Designing Life Itself
If virtual twins can revolutionize healthcare and preserve digital identities, what’s next? AI is already pushing boundaries in biology—allowing for breakthroughs like creating children from any cell in your body. Two mothers, two fathers, or even a single individual could have a biological child. This technology could address infertility and empower diverse families, but it also forces us to grapple with ethical dilemmas around designer babies and the very nature of life itself.

Where Do We Go From Here?
AI is rewriting the rules of biology and medicine, offering hope for rare diseases, immortality through digital legacies, and even redefining reproduction. Yet, with these advances come challenges—ethical, legal, and deeply personal.

As we stand on the edge of this brave new world, one thing is certain: AI is not just transforming how we live but how we define life itself.

What do you think about the possibilities AI is opening up? Are you excited about the future—or cautious about its implications?
