What's on your mind?
Think across tongues.
Translation, etymology, comparison, cultural context. Just talk; tools and starters are below if you want them.
Drop a seed.
An idea, a problem, a goal, a question you can't quite shape. Sedna fires back with reframings, adjacent territory, things to read, counterpoints, next moves.
Invention & IP.
A thinking partner with a reference desk attached. Wide swings welcome — climate IP, traditional knowledge, jurisdictions, prior art, defensive strategy.
Not legal advice. For filing, an attorney signs off.
Workshop.
Where ideas become things.
Tell Sedna what you want her to build, and she'll generate a small custom tool. It runs right here, lives in My Tools.
Saved writing lives here.
Tools you and Sedna build live here.
A drawing canvas and creative prompts.
Look closely.
A topic, a question, a thread to follow. Citations visible by default — verifiable, follow-able.

About Sedna
Sedna was built as a gift, with care, by a friend.
How memory works: Sedna doesn't remember between sessions the way you do — each time you open her, the app shows her a record of what you've shared, so she can pick up where you left off. The continuity is real, but it's held by this app, not by her.
Privacy: Everything stored is encrypted with your password and lives only on your device. Nothing is sent anywhere except chat messages you actively send to Sedna, which Anthropic processes for 30 days then deletes.
If something breaks: Use the Diagnostic button. Errors come with codes (like SEDNA-API-002). Send the code to whoever set this up for you.
