Early access for towns and cities. We are piloting with our first municipality and taking a few more partners for 2027.

AI-first, with a person in the loop

Castorix is built so assistants can do the tedious parts of municipal work: drafting, translating, summarizing and answering. Your staff stay in charge of what residents see.

A staff assistant in every application

  • Draft and rewrite pages in plain language
  • Translate between English and French for review
  • Write alternative text for images
  • Check a page for accessibility problems before it publishes
  • Summarize a resident’s history across applications

“It drafted the French version of our snow page in seconds. We fixed one word and published.”

“Ask Tanglewood”: answers for residents

Residents ask in their own words, in English or French. The assistant answers only from your published pages and your library catalogue, and links to its sources. If it doesn’t know, it says so and points to a person.

Ask Tanglewood
When is recycling picked up on Birch Street, and is the library open on Remembrance Day?
Searched 2 pages and the library hours
Here’s what I found
  • Birch Street is in Zone B: recycling every second Thursday. The next pickup is November 13.
  • The library is closed on November 11 and reopens November 12 at 10 am.

A smarter library catalogue

The assistant fills in missing subjects and summaries when you add a title, and suggests what to read next based on what residents borrow, without sharing anyone’s reading history.

Ask questions of your own data

“How many loans were overdue last month, by age group?” Staff ask in plain words and get a table, a chart and the query behind it, limited to the data their role can already see.

Principleswe don’t bend

Human review

Nothing an assistant writes reaches residents until a person approves it.

Data stays in Canada

Models run in Canadian regions. Your data doesn’t cross the border to be processed.

Never used for training

Your residents’ data is never used to train models, ours or anyone else’s.

Every action logged

Each suggestion and each approval is in the audit log, with the person who accepted it.

Your choice of model

Administrators choose which model powers each assistant, or switch AI off entirely.

Accessible output

Plain language, alt text and heading structure are checked on every draft.

Getting started is easy.

Start with one application and a pilot group of staff. We import your data and you keep your domain.
