Your constellation
Partners with a species, pronouns, an age, a relationship type and a face. Search is fuzzy by default and takes a regular expression if you wrap it in slashes.

Tera
Somewhere for the people you have imagined to live.
Tera keeps the relationships you have with characters who do not exist — the partner, the world they came from, the lore you wrote at 3am, the day you started counting from. It is offline first and yours alone: no account, no sync, no server that has ever seen a word of it.

What it does
Journeys and milestones
Count the days since you started. Months clear as they pass, and milestones sit ahead of you from one month out to ten years.
Lore that survives the import
Bring in Markdown, plain text or a PDF. Keep it as one entry or split it at every heading — a 34,000-word document becomes chapters, attached to a partner and a world.
Messages, on your key
Conversations run through whichever provider you bring — the system prompt is written from the partner's own profile, and you can edit it, set the temperature, and see what each reply cost you.
Galleries and scrapbooks
Folders, captions and #tags per partner, searchable. Commissions in one folder, everything else in another.
Two palettes
Rose Quartz or Sapphire Mist, chosen during onboarding and changeable at any time. Both are soft enough to read at night.
Two files, two jobs
.trbz
the whole of Tera — restoring one replaces everything
.dexpack
characters only — importing one only ever adds
Both formats are ordinary zip archives. Tapping either one in a file manager opens it in the right place — more about how that works.
