The record

Purpose: DBQuill is an open-source, local-first AI database agent for asking questions in natural language, reviewing database operations, and viewing charts.
Database support: It supports SQLite and provides read paths for MySQL 8.4 and PostgreSQL 17.
File imports: Users can attach CSV or .xlsx files, which DBQuill converts into a local SQLite database; legacy .xls is not supported.
Write controls: Writes require validation, a change preview, and explicit confirmation; remote DDL is blocked.
Model compatibility: DBQuill accepts an OpenAI-compatible text-model endpoint and does not require a specific model vendor.
Security: Reads are single-statement and row-bounded, and SQLite reads use physical read-only connections plus query_only.
Local data: Database credentials, model profiles, sessions, audit records, and uploads are stored locally outside the source tree.
Audit privacy: Audit records retain controlled metadata and hashes rather than raw prompts, SQL, credentials, or result rows.
Supported platform: The current release target is Windows 10 or 11 x64 with CPython 3.12 and Microsoft Edge WebView2 Runtime.
Distribution: DBQuill is source-first and does not yet provide a signed native installer.
Other platform limits: macOS, Linux, Windows on ARM, and other Python versions are not release targets yet.
Support: Support guidance directs users to the installation guide, diagnostics, and GitHub issues; no response-time or bounty guarantee is offered for security reports.
Intended users: The project describes natural-language querying and controlled updates for people working with SQLite, MySQL, or PostgreSQL databases and tabular files.
