Used in production by
tensort — A desktop analytics product that runs actain in production — its users ask for what they want in plain language, and actain operates the app to get it done.
Works with
ReactVueSvelteAngularNext.jsplain HTMLEvery app has a long tail nobody can quite figure out.
The buried setting. The five-step form. The report no one knows how to build. Every team patches it with tooltips, tours, help docs, and a support queue — rebuilt for every app, forever. No one ships a drop-in expert who actually knows your product and can do the thing.
So we built one.
What it is
An expert that operates your app — and does the work.
Drop in one line. actain reads your live screens and acts inside them — understands the request, fills the form, opens the right view — then hands your user the final click.
01
Understands what people mean
Plain language — “where do I export this?”, “switch me to the Pro plan”. No menu to memorize.
02
Acts on your real screens
It fills the form field by field, opens the right view, flips the toggle — inside your actual app.
03
Hands over the final press
On your own site the last click stays the user’s — actain gets everything ready, they confirm.
We build the expertise. It never ships to the browser.
✦
We never store your code. It’s read once to build your expert, and it isn’t retained afterwards.
✦
The expert we build for you is our IP. It lives on our servers and never ships to the browser.
✦
The widget on your site only ever receives an encrypted slice, in transit — never the full thing.
✦
Every customer is fully isolated. No one’s setup can ever reach another’s.
EU AI Act — the widget always discloses it’s an AI; never impersonates a human.
GDPR — no end-user personal data kept beyond the session.
SOC 2-aligned controls — AI disclosure, input checks, and customer isolation built in.
Point it at your app. Nothing to rebuild.
actain reads your front-end the way a person does — through what’s on the screen. So it doesn’t care how you built it. One line to embed, and it’s in.
Not that kind of assistant
Everyone assumes it’s a chatbot. It isn’t.
The category actain belongs to didn’t exist yet, so here’s the honest comparison against the three things people mistake it for.
A support chatbot
Answers questions with links and articles, then hands the work back to your user.
✦
Does the work. It opens the view, fills the fields, walks the flow — inside your real app.
A coding copilot
Helps your developers write the app, at build time, in the editor.
✦
Helps your users operate the app, at run time, on the live screen.
A scripted product tour
Replays the same fixed steps for everyone, and breaks the moment the UI moves.
✦
Reads what’s actually on screen right now and decides from there — no step list to maintain.
Straight answers
The questions we actually get asked.
Ask the assistant above any of these in your own words — it answers from exactly this, and says so plainly when something isn’t there yet.
Is this just another chatbot?
No. A chatbot answers and hands the work back to your user. actain does the work — it opens the right view, fills the form field by field, and walks the flow inside your real app.
Do I have to rebuild anything?
No. You drop in one line of script. actain reads your live screens the way a person does, so the framework and the codebase stay exactly as they are.
Does every request go to an AI model?
No — and that’s deliberate. The everyday requests are answered instantly on the page itself, with no round trip. Only the genuinely new or ambiguous ones go further.
What happens when it isn’t sure?
It asks instead of guessing. An unclear request comes back as a short question with the likely options, and anything it can’t do it says so plainly rather than inventing an answer.
Who presses the final button?
Your user. On your own site actain gets everything ready — the form filled, the right screen open — and the last confirming click stays with the person.
Web or mobile?
Web front-ends today — React, Vue, Svelte, Angular, Next.js or plain HTML, including apps behind a login. Native mobile apps aren’t supported yet.
Can we self-host it?
Not today. The expert we build for you lives on our servers and never ships to the browser — that separation is what keeps it ours and keeps every customer isolated.
How do we start?
It’s a short conversation: you show us your app, we build your expert, you drop in one line. Request access and we’ll set up that call — no account needed to begin.
What does it cost?
There are no public tiers. What actain runs for you and how complex your product is set the price, so we scope it together on one short call.
Priced around your app, not a tier list.
No public plans. What actain runs for you — and how complex your product is — sets the price, so we scope it together in one short call. Request access and we’ll talk specifics.
Founding cohort
Put an expert inside your app.
We’re onboarding a small first group of SaaS teams. Leave your email and we’ll reach out to build your expert — no account, no commitment.
actain is an AI. It reacts instantly in the demo above; on your own site, a human presses the final action.
