What AI model does Dayora use?
OpenAI's GPT-5.6 Terra, for everything that reads what you wrote.
Which model does which job
The reply to every entry
OpenAI GPT-5.6 TerraWhat it heard, what is underneath, and, when it fits, one small step.
Reflect conversations
OpenAI GPT-5.6 TerraThe same model, carrying memory of what you have written before.
Voice journaling and call transcription
OpenAI gpt-transcribeRuns with language auto-detection, so an entry spoken in any language is transcribed in that language rather than forced into English.
Your Circle, patterns and long reports
OpenAI GPT-5.6 TerraThe same model family, on longer inputs. Some supporting steps, such as sorting and tagging entries, run on a smaller OpenAI model.
What the model does with what you write
Your entries are sent to OpenAI to generate your reflection, your replies in Reflect, and your transcripts. Under Dayora's agreement with OpenAI, that content can also be used by OpenAI to train and improve its models, and in exchange OpenAI provides a daily allowance of free usage that helps keep the free core free. Dayora does not train a model of its own on your writing, does not sell your entries to advertisers or data brokers, and sends them to one other AI company only to test its own accuracy: TypeSafe AI, which checks how entries are sorted and tagged and does not train on them. What it does mean in practice is that your journal is not a sealed room: it is processed by a third party who may learn from it. If that is not a trade you want to make, Dayora is not the right journal for you: you can export everything at any time, and deleting your account from Profile deletes your entries straight away.
Does the model change?
Yes, and this page changes with it, because the name above is read from the same setting the app runs on rather than typed in by hand. If they ever disagreed, the build would fail.
What Dayora deliberately does not say is that it runs "the latest" model. That claim goes stale the day a new one ships, and nothing can keep it true. What is true and checkable is that the replies you read come from a current OpenAI model, the same one on the free plan as on Dayora Plus, while some behind-the-scenes steps, like sorting and tagging entries, use a smaller OpenAI model.
What about other journaling apps?
People ask which model Rosebud, Mindsera and the rest are built on far more often than they ask about Dayora, and this page is not going to guess. None of them publishes it anywhere we can read and verify, and a company's model choice can change without any announcement at all.
That is the same rule Dayora applies to competitors' prices: a figure gets published here only if it came from that company's own site, with the date it was read. You can see how that works on which AI journaling apps are actually free.
