AI that knows you.
Not one that watches you.
Apps for your conversations, plans, and everyday life. Built around the intelligence in your Apple devices.



Come back to the conversation.
When you need to revisit a conversation, search the transcript, play it back, or ask a question. Echo Chamber does the processing on your device.
Find the part you came back for.
Search the transcript, play the recording, and turn what was said into useful notes.

Build on your last session.
Mettle uses your recent sets to work out the next reps and weight. Open “Why this?” to see which progression rule it used and the training behind that choice.
A plan that can change with your week.
Ask the on-device coach to adjust your plan, then review the proposed changes before applying them.

Turn your notes into flashcards.
Memora turns notes, photos, and PDFs with selectable text into draft flashcards. Keep the cards you want, and start studying the material you came to learn.
Let your recall guide the next review.
Rate how well you remember each answer. Memora uses those ratings to schedule the card’s next review.

The more useful an app becomes, the more you trust it with.
We don’t think that should mean sending your recordings, journal entries, or training history to an external AI service. That exchange is The Trade. Our core AI runs on your device.
Each app tells you where it stores your records and which features make a connection, so you know what you’re choosing.
The Obsidian Ridge Labs standardThe work happens here. Core AI runs on supported Apple hardware. Some models need a download before they work offline.
Transcribe without a connection.
Finish model setup while connected. Then switch to airplane mode, record a thought, and read the transcript. Model downloads, purchases, and optional sync need a connection.
