What you can hire for

What goes into a good assistant

Answers from your data

Retrieval over your documents or database, so the assistant answers from what you've checked rather than from memory.

Sources shown

Answers that cite where they came from, as Mawla does for everyday questions.

Voice in

Speech input for moments when typing is awkward: 1in46 records dreams by voice at dawn.

Answers that become actions

MUST's concierge turns an answer into a savable multi-stop plan.

More than one language

English and Turkish in MUST and Mawla; English, Turkish, Arabic (right to left) and Spanish in 1in46.

Inside your app

Assistants built into iOS apps with React Native and Expo, with subscriptions through RevenueCat where needed.

Questions

Frequently asked questions

Will the chatbot make things up?

Any model can. The way to limit it is to answer only from a defined source and show that source. MUST's concierge answers from the app's own curated places; 1in46 interprets against a fixed corpus of about 6,300 passages.

Which model do you use?

Claude powers the assistants in MUST and 1in46. The choice depends on the language, the cost per conversation and how answers are checked.

Can it work in Turkish or Arabic?

Yes. MUST and Mawla run in English and Turkish, and 1in46 in English, Turkish, Arabic (right to left) and Spanish.

Can it go on our website instead of in an app?

Yes; the same retrieval and model calls work behind a web chat. The live examples here happen to be inside iOS apps.

Want an assistant that answers from your own data?
