Useful to know
Frequently asked questions.
Does Kaiako need a paid AI API key?
No. Summaries, terms, questions, and lesson chat have a no-API-key extractive and retrieval-based default. Optional AI providers require internet access and may have quotas or charges.
Can I transcribe a long video on a small EC2 instance?
Whisper runs locally on the server, but tiny instances have limited RAM and CPU. Start with short files and the tiny model; the included deployment guide adds swap and explains the resource trade-offs. Swap helps avoid out-of-memory failures but does not make CPU transcription fast.
Will Kaiako email my score automatically?
No email is sent without an explicit confirmation. After a lesson is processed and after quiz submission, Kaiako offers a clear choice to send the summary, quiz, and/or score. Email delivery requires configured SMTP or Amazon SES settings.
Is my uploaded media public?
In AWS mode the recommended configuration blocks all public access and uses short-lived presigned URLs. Local mode stores files on your machine. Keep the IAM role, bucket policy, HTTPS, and operating system updates configured as described in the deployment guide.
What if YouTube captions are unavailable?
Caption retrieval depends on the video, caption availability, and YouTube's access restrictions. Kaiako falls back to letting you paste a transcript or lesson text.
