Is the recording length still limited to 90 minutes? Are there plans to raise this as the model's context improves? What is the current AI model(s) used for transcriptions, edits, and other functions? Thank you.
I want to know - who are the AI Companies that are being used to process my data? Can I choose to opt out of any specific AI company - for example - OpenAI?

A: Thank you for asking!
Letterly uses trusted third-party AI providers to process recordings and text. At the moment, we use ElevenLabs for transcription and OpenAI for rewriting.
We continuously work on improving the quality of Letterly, so the exact providers we use may change over time depending on the task and the quality of the results.
At the moment, we don’t offer the option to choose...
Error device limit on Android even though I have 4 devices limits. I get an error when trying to add a 4th device on another email with only 1 device. Why is this error appearing? How can I contact you?
If I want to set a shortcut for detection as the left command on my MacBook, why am I not able to do that? In other applications, I am able to do that. Why in this Letterly AI am I not able to set only the left command to start the detection? Is this some kind of bug or something, or are we not able to set a single keyboard key, like only the left command?

A: Hi, thank you for reaching out. Could you please find the "Set shortcut" option in the app settings? Would that help? Is that what you're referring to? Thank you :)
I know how to set up keys and have already set different ones. But when I try to assign only the left or right command key, like setting the right command key just for dictation, it doesn't work. Is this some kind of bug?
