🇺🇸 Glancer — Ask your Rails database questions in plain language

A Rails engine that allows you to query the database using natural language, with RAG and LLMs. No need to write any code.

Every Rails project reaches a point where someone on the team (product, support, management) needs data, but no one has time to write a quick query for them. You know the drill: a Slack message, a GitHub issue titled "how many users signed up last week?", or a CSV request that ends up in someone's backlog.

So, I think about Glancer.

What it is

Glancer is a Ruby on Rails engine that mounts a full chat interface at /glancer inside your app. You type a question in plain language, it retrieves the relevant schema context, generates a SELECT query (or an ActiveRecord expression), validates and executes it safely, then returns the result with a human-readable explanation.
