The most common question a visitor brings is one that depends on their own document. A tax filing, a contract, a transcript, a CSV of orders. Asking them to paste the relevant section into chat is friction. Most visitors will copy too little, lose formatting, or simply give up. A file upload that just works turns a refused conversation into a productive one.

SleekAI accepts uploads inside the chat widget, scans them with the WordPress filesystem and your configured antivirus hook, and parses them into plain text using a local PDF and DOCX parser. The extracted text is added to the model prompt for the next reply only, then either retained or purged per your bot configuration. Uploads themselves live in wp-content/uploads under a private subfolder, never linked publicly.

The hard parts are size and security. A 50 MB PDF will not fit in any context window, so SleekAI trims to the requested pages or sections. Random binaries should never be accepted, so an extension and MIME-type allowlist is enforced server-side. Generic chatbots either skip uploads or send the file to a third-party SaaS, which means visitor documents leave your stack entirely.

Without file upload, every document-driven question becomes a copy-paste exercise that visitors silently abandon. With upload working, the bot becomes the front door for tasks visitors used to escalate immediately to support. Contracts, invoices, tax forms, lab results, transcripts.

All of these are routine questions for the people who produced them, and routinely hard questions for the bot if it cannot see the document. The trust threshold for uploading a document is much higher than for typing a question. Visitors will only attach a file if they believe the bot will read it safely and forget it later.

That is why SleekAI keeps uploads inside your own WordPress install instead of routing them through a third-party SaaS. Documents never leave your stack. The parsing happens in PHP, the storage is private, and the retention is short by default.

Operationally the upload feature also reduces the volume of escalations to human support. A bot that can read the visitor's own contract gives a competent first answer that resolves perhaps half the questions outright. The remaining half arrive at support already triaged, with a transcript that points at the right clause.

That changes the economics of running support, especially in regulated industries where the alternative is a human reading every document from scratch.
