What Soiniche scans
This page lists exactly which sources the engine actually reads — and which it cannot. If you sell results on trust, you have to state both.
Sources we do scan
Everything goes through public search results (Google, Vietnam region, Vietnamese). We only read what Google has indexed — no logins, no paywalls, no private data.
-
Websites on .vn and com.vn
Who is already talking about the idea, niche or name you asked about.
*.vn · *.com.vn
-
Company registry portals
Identical or near-identical company names, from published records.
thongtindoanhnghiep.co · masothue.com
-
Intellectual property portals
Hints that a trademark has been mentioned. A hint, NOT an official search.
ipvietnam.gov.vn · *.gov.vn
-
E-commerce marketplaces
Products or shops using the same name.
shopee.vn · lazada.vn · tiki.vn
-
Android app store
Apps with the same name, read via Play Store pages Google has indexed.
play.google.com
-
Vietnamese forums
What real users say — the source behind the pain-quote table.
voz.vn · tinhte.vn · webtretho.com · otofun.net
-
Job boards
Signals that companies are hiring in that space.
topdev.vn · itviec.com · vietnamworks.com
-
News outlets
Whether the niche gets press coverage, and how recently.
vnexpress.net · cafef.vn · techinasia.com
-
Social media (public parts)
Only pages Google can index. Private groups are off limits.
facebook.com · tiktok.com · instagram.com
What we cannot scan — plainly
The engine does not read any of the following. If a report is silent about them, that is missing data — not an absence of competitors.
- Whether a .vn domain is free or taken — no real source wired yet, so that number is absent rather than guessed.
- The iOS App Store — not wired; iOS apps with the same name may be missed.
- Private Facebook groups, Zalo, direct messages — private data, never touched.
- Content behind paywalls, and sites that block bots.
- Deep per-competitor page reads (paid tier) — not open yet.
Anonymous vs signed in
- Anonymous scan: only numbers counted by plain code. NO sentences written by AI.
- Signed in: adds analysis and tables written by a language model — every sentence must cite a source, and any that cannot is stripped before it reaches you.
- Paid tier: not open yet.
How the numbers are produced
- Counted by plain code from the fetched results — no model involved.
- Estimated indirectly by a pure function; a proxy, not a direct measurement.
- A table extracted by a model, where every row must point at a real piece of evidence.
- Analysis written by a model, required to carry evidence markers [E#].
Your data
Scan results are kept for at most 180 days, then deleted automatically. Never sold. You can delete them sooner at any time.
