Show IH: I built a free AI doc generator that runs 100% in your browser — no login, no server

The no-login, 100% client-side constraint is genuinely
a product decision, not just a technical one.

Most AI tools build retention around accounts — saved
history, return visits, email sequences. You're betting
on a different mechanism: trust as the growth lever.
Users share tools that don't feel like surveillance.

The discoverability challenge is real though. Without
accounts you have no activation funnel, no re-engagement,
no way to know who your power users are. The comment
above about repeat usage is exactly the right question.

One thing that might work in your favor: documents often
contain sensitive content — contracts, HR notes, client
briefs. The "no server, no data handoff" angle is
actually a feature for that audience, not just a
technical curiosity. Leaning into that positioning
explicitly ("generate confidential documents safely")
might sharpen who you're for.

Congrats on the launch — what's been the most surprising
feedback from early users?

The 'no login, 100% in browser' constraint is interesting to validate against - it removes the retention lever most AI tools rely on (saved history, account = return visit habit).

The users who get the most value from no-login tools tend to have very specific, repeatable tasks they bring their own context to. They do not need you to remember them - they have the context in their head and just need the processing power.

The validation question: who comes back a second time, and why? First-time users are everywhere. Repeat users on a no-login tool are almost always people who solved a very specific problem and need to solve it again.

For AI doc tools specifically: the users who come back tend to have a narrow use case - 'I need to format this specific type of document, every week.' If you can identify that use case from early users, that is your product.

What are you seeing in terms of repeat usage, even without accounts to track it?

Hey—tried docreplacer and this is a genuinely strong value prop: I can generate a .docx instantly with no login/account and everything runs in-browser, so it feels safe.
UX-wise, the preview before download and the ability to edit on the browser are great.

A couple of questions/feedback:

1.What model(s) are you using under the hood? (and how consistent is Japanese output vs English mixing)
2.For reports, would you support richer visuals like charts / Mermaid diagrams / simple illustrations?
Also, how “fresh” is the knowledge/data you rely on (if any)?
Overall: promising—would love to see more formatting/diagram controls.

The strongest part here is not just “AI doc generator.” That category already sounds crowded. The sharper angle is private document generation: prompt to .docx, fully in-browser, no login, no server, no account, no data handoff.

That matters because documents often contain sensitive client notes, contracts, internal drafts, or personal information. Most AI writing tools ask users to trust a backend. Your wedge is simpler: generate the file without the product becoming part of the data chain.

One thing I’d watch is the name docreplacer.online. It sounds more like a utility action than a product brand, and “replacer” may not fully match what you’re doing if the core value is generating private Word documents from prompts. If this expands into a broader private document workflow tool, Xevoa .com would feel cleaner and more platform-ready.
