Workbench is the reusable context you keep in the Browser App: Prompts you insert into the composer, Personas that set the assistant’s tone, Knowledge entries (labeled Source in the Library) that give a chat reference material, and Preview Context, which shows the assembled request before it goes out. Included with Advanced and Max. Free and Plus accounts see the Workbench sections with a View plans action, and anything saved earlier stays in the browser after a downgrade. Everything in Workbench is encrypted in your browser and stored locally. Nito receives it only inside the chat requests you send.

Library and Active Context

Open the + control in the composer, or Library & context from the account menu.
  • Library is where you create and edit Prompts, Personas, and Sources. A Source can be typed or built from a document; text-like files parse in your browser, larger documents such as PDFs go through Nito’s no-store parser.
  • Active Context is what applies to the current chat. Prompts insert once. Personas and Sources stay attached until you remove them.
Each Source remembers the privacy level it was created under and replays only into chats at that level or higher. The same rule governs memory. Chat summaries can be published into Knowledge from the summary review. Incognito chats never save to Knowledge.

Prompts

Slash-style snippets for the jobs you repeat. Inserting one fills the composer; it does not persist as context.

Personas

A Persona replaces the built-in Default Style with your own instructions, compiled into the system prompt under User Persona. New accounts start with No persona. One Persona is active per chat.
  • Settings > Text > Custom instructions adds persistent guidance to every text chat, whatever Persona is active.
  • Tune Persona on a reply turns your feedback into an updated Persona without copying the reply itself.

Knowledge

Selected Sources are injected into the request under Additional Context, labeled as reference data rather than instructions. Keep each entry under the character limit shown in the editor.

Preview Context

On Advanced and Max, Preview Context in the composer opens the exact request the send path will build: base prompt, active Persona, selected Sources, and an approximate token count for each. Free and Plus accounts find it described under Settings > Intelligence.

Sharing

Prompts, Personas, and Sources share by encrypted link; the recipient imports a fresh local copy. See Sharing.
