Teclis is an attempt to surface the less known web, the web of creativity and self expression, the more humane web.

Teclis includes its own crawl as well as results from Kagi Small Web index and results with permission from Marginalia Search.

Teclis works best with broad queries such as 'machine learning', 'vegan diet', 'religion' etc..

If you get "Captcha verification failed' message, reload the home page, and patiently type your query again (this is antibot protection).

The crawler is hybrid, using async python requests and puppeteer with uBlock Origin. The way detection works is we count the number of uBO blocked requests on the page, and if too many (threshold is set to 5), we kick it out, leaving only "clean" pages in the index.

Crawler is also unique in a sense that it will follow an interesting dead link to its internet archive page, trying its best to preserve the page in our index (you will see those results under "Internet Archive" section).

Content and semantic metadata is extracted using trafilatura and readability.js, while page language is detected using fastText.

To produce search results, triple rankings with full-text search (via Elasticsearch / Typesense) and NLP-based semantic search (using sentence transformers to produce embeddings and SCANN to search through vector space) are combined to produce final ranking of results. Responses are served using FastAPI.

"Interesting Recently" section is provided by TinyGem, a content recommendation and bookmarking tool built using similar stack.

Teclis also uses results with permission from Marginalia Search (another noncommercial search engine).

Teclis was built by Vladimir Prelovac, founder of Kagi Search.
