The entire page load. Heavy files wait until the visitor shows search intent; you can watch this happen in the demo above.
Your visitors find what they mean.
Semantic search for your site, running entirely in the visitor's browser: no server, no subscription, no per-query fees.
Live demo: Turkish Wikipedia, astronomy

The demo searches Turkish content. Click a sample query above.
The index does not download until you type.

Keyword search cannot find these.
Visitors do not know your page titles; they type their own words. lightembed matches meaning instead of words, so the right page comes up even with zero overlap.
how do I get a tax refund->Income tax return filing process
my package still has not arrived->Order tracking and delivery
how do I close my account->Account deletion steps
In all three, the query and the page title share no words. Left: what the visitor typed. Right: the page that should be found.
No server. Really.
Indexing runs once on your machine and produces static files. The only thing that runs for a visitor is a small search engine in their browser.

Setup is three commands.
No server to run, no API key to manage, no pipeline to tune.
1. Get the content
Skip this step if you already have a content folder. Crawl only when the live site is all you have.
# download the live site, obeys robots.txt
npx lightembed crawl https://siteniz.com/dokumanlar/ --out ./icerik
npx lightembed crawl https://siteniz.com/dokumanlar/ --out ./icerik
2. Index
Splits pages into chunks, turns them into meaning vectors, writes a static bundle.
# index
npx lightembed index ./icerik --model ./model-tr.bin \
--out ./public/lightembed --base-url https://siteniz.com
npx lightembed index ./icerik --model ./model-tr.bin \
--out ./public/lightembed --base-url https://siteniz.com
3. Add to your page
One script tag and one element. The bundle works on any static hosting.
<!-- on your page -->
<script type="module" src="/lightembed/widget.mjs"></script>
<lightembed-search src="/lightembed"></lightembed-search>
<script type="module" src="/lightembed/widget.mjs"></script>

14-day no-questions refund. 12 months of updates included; $10/yr after, only if you want them.

Updates
Every improvement for 12 months; lightembed update is one command. When it ends, the version you have works forever; stay current for $10/yr if you want.
If the command line is not for you
A hosted tier is coming: give us your URL, we index it and keep it fresh as your content changes. Monthly subscription, zero setup.
The visitor's bill, byte by byte.
Every number is measured, not calculated: a test generates this table, nobody types it. A visitor who never searches pays only the first row.

Measurements
We will state our limits ourselves.
A better free model exists and it is 36 times larger. If you want the quality ceiling, use it; if shipping 118 MB to every visitor is unacceptable, lightembed exists for that.
| Model | Quality, STS22 | Ships to browser | Quality per MB |
|---|---|---|---|
| lightembed-tr | 0.450 | 3.24 MB | 0.139 |
| potion-multilingual-128M | 0.504 | 128 MB | 0.0039 |
| emrecan bert-base-turkish | 0.563 | 110 MB | 0.0051 |
| multilingual-e5-small | 0.673 | 118 MB | 0.0057 |
The table comes from our own test rig; commands and raw results are in the repo. Per compressed megabyte, the gap in our favour is 24x.
Every result can be audited.
Search uses both meaning and keywords. An inspection tool ships with every index: where each result came from, each side's contribution to the score, and what changes when you adjust the weight.
On your own data, the lightembed explain command prints the same output.
Short answers.
Will anything run on my server?
No. The output is plain static files; GitHub Pages, Netlify or your own hosting, it makes no difference. Nothing ever phones home.
What happens when my content changes?
Run the same indexing command again. Unchanged pages come from cache; only new and edited pages are processed.
Why Turkish only?
General models do not understand Turkish suffixes. This model is trained for Turkish; focusing on one language is also why it can be this small.
Is the quality enough for me?
The demo above is the real product, not a polished mock. Try your own questions; if it does not convince you, do not buy it.
What if I don't like it?
Email within 14 days, refund with no questions. The demo is the real product, so most people know before they buy.
How do updates work?
lightembed update downloads the newest release. First 12 months included; $10/yr after, optional. Skip it and what you have keeps working.
