Tedin Inc. · founded 2021
We have always been in the business of wayfinding
Someone arriving somewhere new. Someone who loses a road they know. Someone who forgets the road just walked. The people changed; the work never did — shortening the distance between whoever is asking and wherever the answer sits.
Mission
We close the distance between a question and its answer.
Across every page a company passes through, we connect questions to responses at the level of the phrase.
How we got here
Only the people changed. The problem was always one.
The work moved from tourism to welfare, from industry to the web.

- TodayAn explanation layer over web pages and videoSomeone lost mid-read
We did not switch fields. We solved one problem again, somewhere else.
And now
This time people lose their way inside the screen
Someone stops at one line of a form and leaves the page to look for help — search, FAQ, a downloaded manual, and when none of it works, a screenshot attached to a support email. On the receiving end the answer usually already exists, so instead of answering you write an email pointing to where it is. Not a shortage of material: the place people stop and the place the answer lives are simply different.
Question · Search · FAQ · Manual · Support email
So what we built is a Chrome extension, and a web tool for writing and managing what it shows.
- An underline becomes a questionIt arrives with the page and the wording attached, and where people get stuck accumulates without anyone being surveyed.
- A click opens the explanation in placeWhen words are not enough, only the needed segment of a video plays, then stops. In video it sits at that moment on the scrubber.
- Written once, it opens on the pages you chooseExplanations attach to the phrase, not the address. If the wording survives a revision, so does the explanation.
What we do not do
Stated up front
The things that would be awkward to discover later.
We never edit the original
Notices, regulations, videos — all untouched. What we add is one layer above them.
We do not write your answers
Only the people who do the work can say why a passage is hard. We connect the question to the response.
We do not know who asked
Underlined questions from public pages carry no personal identifier. We count what is missing, not who pressed.
It does not work everywhere
Desktop Chrome. A link you receive opens without installing, but underlining to ask requires the extension.
Founder
Bongjin Seo
CEO & Chief Research Officer
He led the pilots above himself — from the sandbox application through the work on Chuja Island, and now the design of the tool itself. He heads KRAI (Korea Responsible AI) and lectures at several university graduate programmes.
- What he researchesCombining intuition (neural networks) with rules (symbolic logic) so results can be explained and are not invented — neuro-symbolic AI. And modelling intent and context as one knowledge graph, so search runs on meaning rather than keywords.
- Intellectual property2 patents granted · 8 filed · 1 trademark · 1 design.

We will make the way visible where people stop
Name one page and we will build it for you. No installation needed — the URL you get asked about most, or one video. No sales follow-up.
