Turn noisy YouTube comment sections into a filtered stream of user feedback
Machine learning sorts every comment into categories so low-signal replies never reach your inbox.
Feature requests, bug reports and questions are collected and delivered as one consolidated stream.
Jokes, spam and emoji-only replies are filtered out, leaving only messages with product value.
You pay per thousand comments analysed, so the bill scales with your upload activity rather than a fixed seat.

Free AI-powered PDF editor, converter and reader for every device
Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos.
Translate whole documents, including scanned and image-based PDFs, into 20+ languages while keeping the original formatting and layout intact.
Convert invoices, receipts, bank statements and purchase orders into structured, editable Excel files automatically.
Edit text and images, OCR scanned pages, convert to and from Office formats, then merge, split, compress, watermark, sign and annotate.
