The story behind SageGate
Founder's Notes
I built SageGate because I kept running into the same wall.
Every time I wanted to try a different AI model, I had to open a different app, log into a different account, and start from scratch. There was no context, no memory, and no connection to anything I actually cared about.
The AI never knew anything about me. It could not see my files. It had no idea what I worked on yesterday. Every single conversation started cold.
That bothered me. Not because it was inconvenient, but because it felt like the technology was being kept at arm's length from the people who could benefit from it most.
What I wanted was simple: one place where I could talk to any AI model I choose, using my own API keys, connected to my own files and notes, with a memory that actually carries over between sessions.
I wanted a tool that works with my life, not a demonstration of someone else's idea of what AI should be.
So I built it.
01 · Choice and continuity
One Place, Any Model
SageGate brings the models you choose, the information you trust, and the way you work into one place.
No single AI model is best at everything. Some are stronger at writing. Some reason more carefully. Some work better with code, documents, images, or long context.
SageGate does not make that choice for you. It gives you one consistent workspace where you can connect the providers you trust, use your own API keys, and move between models without rebuilding your entire setup.
Your conversations, memories, files, Skills, and scheduled work stay organized around you rather than around one provider.
The model can change. Your workspace does not have to.
02 · Clarity
Clean Information Matters
Clean information helps an AI retrieve the right context and provide a response that is more relevant to you.
If you have a choice, saving or converting your documents to Markdown (.md) before attaching them will usually produce better results than uploading a PDF, Word document, spreadsheet, or slide deck directly.
Those formats often contain invisible formatting, layout information, and other structural details that can interfere with the model's ability to identify the actual meaning of the document. Markdown preserves headings, lists, emphasis, links, and logical organization without surrounding the content with unnecessary formatting.
You do not have to manage that work yourself. You can also let SageGate handle the process from beginning to end: extracting readable text, dividing it into useful chunks, creating embeddings, and organizing it for retrieval.
A vector database can then help RAG or agentic search find the passages that matter for a specific question. The language model receives context drawn from your own information, so its answer can be more accurate, useful, and tailored to you.
The cleaner the source and the stronger the retrieval, the better the model can focus on what you are actually asking it to understand.
03 · Responsibility
Visibility Before Autonomy
AI should help you do more without hiding what it is doing or what it costs.
When SageGate sends a request, you can see how many tokens went into the message, how many came back, how much information was retrieved from a cache, and how many tokens were used for reasoning. You can see the cost of each message and the running total.
I do not show these numbers to overwhelm people. I show them because I believe you deserve to understand what you are using and what you are paying for.
AI agents are powerful. But power without visibility is simply a bill you do not understand at the end of the month.
AI is currently most accessible to people who are already technically comfortable: developers, researchers, and people working at large organizations with the resources to build custom tools.
That is not how it should be. AI should help everyone, regardless of their background. That belief is built into SageGate, and it is also reflected in what I intend to do with it.
Starting in July 2026, 10% of monthly App Store proceeds will be donated to verified 501(c)(3) nonprofit organizations dedicated to animal welfare.
SageGate is one person's attempt to build something honest, useful, and worth caring about.
