Frequently asked questions

How does Knowbase work?
Knowbase combines file storage with AI chat. You upload your files — PDFs, documents, presentations, audio, video, or YouTube links — and Knowbase processes them into a searchable knowledge base. Then you simply ask questions in natural language and get AI-powered answers with source citations pointing to exactly where the information was found.
Is there a free plan?
Yes! By signing up you get 100 MB storage and 25 queries per month for free. It's perfect for testing how Knowbase works with your documents.
What file types are supported?
You can upload PDF, DOCX, DOC, PPTX, TXT, MD, MP4, MP3, AVI, MOV, WMV files, as well as YouTube videos by pasting their links. Google Drive and Notion documents can also be searched directly through our connector integrations.
What is Chat-All?
Chat-All lets you query your entire document library in a single conversation. Instead of chatting with one file at a time, Chat-All searches across all your uploaded files, connected Google Drive, Notion workspace, and web sources to find the most relevant answers.
How do the integrations work?
Connect Google Drive or Notion with one click via OAuth. For Web Search, add the domains you want to search. When you send a message in Chat-All, Knowbase searches your connected sources in real-time, extracts relevant content, and includes it as context for the AI to answer your question.
Can I upload videos and audio?
Yes! Knowbase automatically transcribes video and audio files using AI speech-to-text with automatic speaker identification. Once transcribed, you can see who said what, rename speakers, export subtitles (SRT/VTT), and chat with the content. You can also paste YouTube links to transcribe and chat with YouTube videos.
Can I share my knowledge base?
Absolutely. You can generate shareable links for individual files, collections (Nests), or your entire library. Recipients can chat with your content without creating an account. You can also embed the chatbot directly on your website.
What languages are supported?
Knowbase supports 50+ languages including English, Polish, Spanish, French, German, Chinese, Japanese, Arabic, and many more. The AI responds in the same language you ask your question in.
Does Knowbase identify speakers in transcriptions?
Yes! When you upload a video or audio file, Knowbase automatically identifies different speakers in the recording (speaker diarization). You can rename speakers to real names, and even ask questions scoped to a specific speaker — for example, "What did Sarah say about the budget?"
Can I embed a chatbot on my website?
Absolutely. Knowbase lets you embed an AI chatbot widget on any website. Choose between a floating bubble or a side panel, customize colors, title, greeting, and theme (light/dark/auto), then paste a single code snippet into your site. Visitors can ask questions and get answers from your knowledge base.
