I bought IKI.ai at Tier 2 for a rather large project - accessing the history of my city's council and committees, meetings of which are now kept on YouTube. Since the city has stopped producing useful minutes, minutes that actually describe what happened, rather than just a record of decisions, this seemed to be the only way to access the history.
After about 15 days of loading it up I've found
- YouTube linkup is generally seamless and transcription is quickly done
- There is a limit in IKI on YouTube videos = 5 hours. Most of my videos are shorter than that but a few are longer - one as long as 9.5 hours.
- The IKI team has been corresponding with me on the issue but there is no fix as yet
- Yes, help IS available from IKI, despite what one review said. Write to team@iki.ai
A few improvements that would make the transcriptions more useful:
- Break the transcription when the voice changes and also when the voice pauses or seems to change subject
- Allow the voices to be labeled with a name and keep track of the names in my user space

I'm sure I have more to say as I use it. I will be testing it thoroughly before my 60 days is up and will make a decision then as to whether to keep it.
