Three AI products,
live today.
Evi is an everyday AI assistant for work, study and quick questions. Kus gives small models sourced answers they can back up. Revmosys tells you what changed on your website and why. We design, build, and run every one ourselves.
Your everyday AI assistant.
Ask a question, upload your notes or a photo, or check what's happening today. Evi answers in plain words and remembers you next time.
Ask about today
When a question needs current news, prices or facts, Evi searches the web before it answers.
Upload notes, files or photos
PDF, Word, text, CSV and images. Ask about them and Evi answers from what's inside.
It remembers you
Useful details carry across chats, and you can see, edit or delete every memory.
Give a small model answers it can back up.
One API call searches trusted sources and returns an answer with citations, so a small or local model answers from real evidence.
Faster answers
New questions come back much faster than before, still drawn only from trusted sources with citations you can check.
The strongest evidence wins
Results are ranked so the answer is built from the most relevant sources, with citations you can check.
Fast on repeat questions
A question close enough to one already answered comes straight back from cache, without a fresh search.
Your documents stay yours
A shared public knowledge base plus private per-tenant documents, isolated by API key.
RevmosysLiveMost tools show you numbers. Revmosys tells you what broke.
One number, one sentence and one action, sent to you on the 1st of each month.
It won't cry wolf
A jump from 3 enquiries to 6 looks huge on paper. Revmosys knows that's still normal variation and says so before anyone celebrates.
Finds the real break
Fewer people showing up, or fewer of them getting in touch? Revmosys tells you which one, from your own numbers.
Checks what Google's AI says about you
Every month it asks Google's Gemini, with live search, the way a real customer would, and tells you whether your business gets named and who gets named instead.
We build for you, too.
The team behind Evi, Kus and Revmosys builds custom software for companies, startups and individuals.
AI products and assistants
Chat assistants, document search and AI agents, built around your data and your users.
We built and run Evi →SaaS platforms and web apps
Full products with sign-in, billing, dashboards and admin, from first screen to launch.
We built and run Revmosys →Business automation and lead research
Programs that do the repetitive work: research, sorting, reports and data moves.
See Jai, our lead research tool →A studio that ships whole products.
Every product we make is live or in active build, and we run each one ourselves on top of AI models from established providers. Doing the work in house keeps our costs down, so we can offer capable AI at low prices. We design for trust: answers you can check and data you control.
Own products, end to end
We design, build, and run each product ourselves, on top of AI models from established providers.
Affordable by design
We build and run everything in house, which keeps our costs and your prices low.
Answers you can check
Grounded, cited answers and real document understanding, so you can check what the AI tells you.
Priced for students first
We start with the students and developers the industry prices out, then build for everyone else.
Three research projects, running alongside the products.
We run three research projects alongside the products. TDI catches the mistakes AI makes while writing code and corrects them before anyone sees the answer. A second project is an AI modeled on brain cells, designed to keep learning after launch. The third makes existing open-source models smaller so they cost less to run; if it works, we'll offer it through the Evi API. TDI has published results, and the other two are at an earlier stage.
Start with Evi.
Our AI assistant is live and free to try. One 26io account, and one free monthly balance, works across Evi, Kus and Revmosys.
