Turn Any Website into a RAG Knowledge Base: aiFetchly

The Boilerplate Noise Problem in Web-Based RAG

Building a reliable retrieval-augmented generation (RAG) system typically requires writing custom scrapers, stripping messy HTML boilerplate, managing vector database infrastructure, and paying recurring cloud embedding subscriptions. For researchers, analysts, and marketers, turning competitor websites, API documentation, or customer support knowledge bases into usable AI context is an engineering headache.

Raw web pages contain navigation bars, cookie banners, tracking scripts, and footer links. When fed directly into vector databases, this extraneous noise dilutes embedding precision, pollutes retrieval ranking, and causes models to hallucinate during generation.

AI Fetchly eliminates this friction with its Import Website into Knowledge Library engine. Built directly into the desktop client, this feature ingests public web pages, converts them into clean semantic markdown, and stores vector embeddings in your local SQLite database without manual data wrangling.

Three Ways to Ingest Web Content: Single Page, URL List, and Site Crawl

aiFetchly provides three ingestion modes to balance speed and coverage:

Ingestion Mode	Input Parameters	Maximum Scope	Ideal Use Case
Single Page	1 target URL + optional Title override	1 page	Product pricing, terms, or landing pages
URL List	1 to 50 URLs (one per line)	50 distinct URLs	Curated competitor blogs or selected guides
Site Crawl	1 root Start URL + Max Depth / Pages	Up to 100 pages (Depth 0–4)	Complete documentation sites and FAQs

Step-by-Step Tutorial: Ingesting Web Documentation into RAG

Follow this walkthrough to crawl an online documentation site and index it for grounded AI reasoning.

Step 1: Open the Import Website Dialog

1. Launch aiFetchly on your Windows desktop.
2. Navigate to Knowledge in the left sidebar menu.
3. Click the Import Website button in the page header.

Step 2: Choose Your Ingestion Mode and Enter Target URLs

Select between single-page extraction, curated lists, or automated crawling:

1. Select Site Crawl at the top of the dialog.
2. In the Start URL field, enter your public documentation root (e.g., https://docs.example.com/api).
3. Set your crawling boundaries: configure Max Pages (default: 20; range: 1–100) and Max Depth (default: 2 hops; range: 0–4). The crawler strictly adheres to same-origin boundaries to prevent external domain drift.

Step 3: Apply Metadata and De-Duplication Policies

Organize your incoming knowledge assets before indexing:

1. Add comma-separated Tags (e.g., api-docs, competitor-q3).
2. Set the Author metadata (defaults to Website).
3. Set your Duplicate Policy: keep the default Skip duplicates to keep your database clean, or select Allow duplicates to store historical snapshots of updated pages.

Step 4: Execute Ingestion and Verify RAG Citations

Click Import. aiFetchly’s browser scraper loads each page, strips boilerplate HTML, converts the content to clean markdown ({hostname}-{path}-{hash}.md), chunks the text, and writes vector embeddings to local SQLite.

Once complete, open AI Chat or the AI Marketing Assistant (Cmd/Ctrl + K) and toggle the RAG icon (📖). The assistant will cite exact source URLs, paragraph quotes, and verified facts directly from your newly indexed site.

Instant, Private Knowledge Bases on Your Desktop

By converting web pages into discrete, cited markdown records locally, aiFetchly ensures your AI agents reason over grounded truth without leaking data to cloud embedding vendors.
