Frequently asked questions
What 26io Techlab is, what we build, and how each product works.
Company
What is 26io Techlab?
26io Techlab is an independent Ai product studio. It designs, builds, and runs its own Ai products end to end — currently Evi Ai, a personal Ai assistant, and Kus, a knowledge and retrieval API — on infrastructure the studio operates itself rather than reselling.
What does 26io Techlab do?
26io Techlab builds complete Ai products rather than demos or consulting projects. Each product is designed, engineered, and operated in house, from the model pipeline through to the deployed service. Owning the whole stack is what keeps prices low. The studio's stated aim is to make powerful Ai useful and affordable for everyone, not only well-funded companies.
Where is 26io Techlab based?
26io Techlab operates from India and builds for a global audience. Its products are available worldwide and are not limited to any one market.
Is 26io Techlab building its own Ai model?
Yes, at an early stage. 26io Techlab is researching its own lightweight language model — small and inexpensive enough to run almost anywhere, while tuned to perform above its size. This is early-stage research and development, not a released product. The intended route to market is the Evi API.
Products
What products does 26io Techlab make?
26io Techlab makes four products. Evi Ai, a personal Ai assistant, and Kus, a knowledge and retrieval API, are both live. Revmosys, a website-momentum and revenue intelligence engine, and the Evi API, an affordable Ai API for students and developers, are in development.
What is Evi Ai?
Evi Ai is a personal Ai assistant built by 26io Techlab. Unlike assistants that begin writing immediately, Evi first classifies the question and plans the shape of the answer — format, length, depth and what to cover — then writes it, then scores its own reply against that plan and against the sources it actually used. Long-term memory across chats and answers drawn from uploaded documents are included as standard.
How is Evi Ai different from other Ai assistants?
The difference is the pipeline rather than any single feature. Evi Ai separates planning from writing: one pass works out what kind of question was asked, a second decides the format and what the answer must cover, and only then does it write. After streaming, every reply is scored out of 1 against that plan and against the retrieved sources rather than the model's own training. Most assistants begin generating text on the first pass.
Does Evi Ai search the web?
Yes. Evi Ai classifies whether a question needs current information and triggers a live web search when it does, instead of answering from a static training snapshot alone.
Can Evi Ai read documents I upload?
Yes. Evi Ai can answer questions from PDFs and other documents uploaded to it, and ties its answer back to the source text rather than relying on memory alone.
Is Evi Ai related to Hume AI's EVI or Amazon's Evi?
No. Evi Ai, built by 26io Techlab, is a separate, unrelated product from any other assistant that shares the name Evi, including Hume AI's Empathic Voice Interface (also called EVI) and the Amazon-acquired Evi.
What is Kus?
Kus is an API from 26io Techlab that makes small or local language models answer reliably. It searches trusted sources and returns answers with citations. A master router fans each query across three child retrieval systems and nineteen asynchronous source workers in parallel, then ranks results with hybrid BM25 and dense retrieval fused by reciprocal rank fusion, followed by a FlashRank cross-encoder rerank that runs on CPU. Cached questions can return in roughly 150 milliseconds with no model call.
Can Kus use an organization's own documents?
Yes. Kus can blend an organization's own private documents with public web knowledge, isolated per API key, so one customer's documents are never mixed into another's answers.
How fast are answers from Kus?
Cached questions can return in roughly 150 milliseconds with no model call. Uncached questions take longer, since Kus performs live retrieval across trusted sources and reranks the results before answering.
Where is the Kus API documentation?
Kus's public API reference is published at https://kus.26io.com/docs.
What is Revmosys?
Revmosys is a website momentum engine built by 26io Techlab. It tracks how many people find a site, how many get in touch, and what changed, then names which stage of the funnel broke instead of listing every symptom. It applies proper statistical tests so a rise from 3 enquiries to 6 is reported as normal variation rather than growth, and it says when there is not yet enough data for a reliable read. It also checks each month whether Ai assistants name the business when someone asks for one like it.
Does Revmosys use tracking cookies?
No. Revmosys counts visitors with a small first-party script running on the business's own site. It does not use third-party cookies or ad networks, and does not share data with anyone else.
How does Revmosys avoid reading noise as growth?
Revmosys applies statistical tests (Poisson and binomial) to enquiry counts, so a change such as 3 enquiries to 6 is reported as normal variation rather than as real growth, and every score is given with an explicit confidence range rather than a single misleading number.
Does Revmosys check whether Ai assistants recommend a business?
Yes. Each month Revmosys asks Ai assistants the kind of question a customer might use, such as 'best plumber near me', and records whether the business is named — and which competitors are named instead.
Is Revmosys only for one kind of business, like clinics or dentists?
No. Revmosys is built for two broad kinds of website, not one industry: e-commerce sites that sell products directly, and individual or service sites that run on enquiries — a local shop, a professional practice, a studio, an agency, a personal site. It works out which kind a site is from its own behavior (purchases with no calls reads as a store; calls and forms with no purchases reads as a service) rather than from a configured business type.
Does Revmosys ever change my website itself?
No. Revmosys is advise-only. It finds what's fixable and shows the exact change to make, but it never edits a customer's site itself, even on platforms like Shopify where its own access would technically allow it.
How do I connect my site to Revmosys?
Revmosys Connect installs tracking in one click via real OAuth for Webflow, Shopify, and Google Tag Manager, or through WordPress's own official Matomo plugin. Any other platform can use the revmosys-connect command-line tool or a short manual snippet — no developer required for most sites.
Does Revmosys track product sales and Ai-referral traffic, or just enquiries?
Both. Revmosys reads real order data — from Shopify, WhatsApp catalog orders, or a manual purchase hook — to flag when revenue depends too heavily on one product or a product is genuinely declining. It separately tracks visits arriving from Ai assistants such as ChatGPT, Perplexity, and Copilot, and ties that traffic to what it's actually worth.
What does Revmosys cost?
Revmosys is free to use right now — we've just launched, so there's no card required and full dashboard access. Pricing returns once launch ends, and existing users will get notice before that happens.
What is the Evi API?
The Evi API is a planned Ai API from 26io Techlab, in an OpenAI-compatible style, aimed at students and independent developers who need production Ai at low cost. It is also the intended home for the lightweight language model the studio is currently researching. It has not launched yet.
Will the Evi API be compatible with the OpenAI API format?
Yes, that is the design intent — an OpenAI-style API surface with tiered models, so existing tools and SDKs need minimal changes to switch over.
Practical
Is Evi Ai free to use?
Yes. 26io Techlab currently offers Evi Ai free of charge, subject to fair use. Other products may be offered separately, including on paid terms, under their own agreements.
How do I contact 26io Techlab?
26io Techlab uses two addresses. Write to [email protected] for product help, account or sign-in issues, and privacy or data requests. Write to [email protected] for investment, partnership, and press enquiries.
Does 26io Techlab train Ai models on my conversations?
Messages and documents submitted to Evi Ai are sent to Ai model providers so that Evi can generate a response, and those providers process the data only as needed to perform that service. The full detail of what is collected and why is set out in the 26io Techlab privacy policy.
