## ChartDB

ChartDB attacks a familiar annoyance: understanding an unfamiliar or sprawling database schema. Rather than installing a heavy modeling suite with database access, it asks you to run one read-only query per DBMS — the project publishes a ready-made query for PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, ClickHouse, CockroachDB, Oracle, Snowflake, and BigQuery. Paste the output JSON and you get a full, interactive ER diagram that you can rearrange, annotate, and export.

Beyond visualization, ChartDB works as an editor. You can add tables, subject areas, and sticky notes, edit relationships, use a DBML editor for text-driven modeling, and produce clean DDL scripts in your preferred SQL dialect. The AI ER diagram generator goes the other direction: describe what you want and get an editable, optimized schema draft. Diagrams are also exportable as images or embeddable previews for docs and wikis.

The project is open source under AGPL and has accumulated tens of thousands of GitHub stars, which is why a self-hosted deployment is available alongside the Cloud product. Cloud plans add real-time collaborative editing, database auto-sync that keeps diagrams current as the schema changes, change logs and versioning, and an AI assistant. Teams get multi-user workspaces, 2FA, and priority support; larger organizations can request custom SSO and RBAC terms.

**Pricing & Plans:** ChartDB offers a genuinely free open-source tier (self-hosted, AGPL) that includes all core features and up to two diagrams. Cloud plans run about US$25/month for a single user (Pro) and US$59/month for teams, with annual billing discounts of up to 40%. Custom enterprise pricing covers SAML SSO and granular permissions.

- **One-query schema import:** Paste a single read-only query result and ChartDB renders the whole schema as an ER diagram, with no direct database access or local agent required.
- **AI ER diagram generator:** Describe a database idea in plain language and get a fully editable, optimized ER diagram that you can refine and export straight to SQL.
- **DDL and diagram export:** Export clean DDL scripts in your preferred SQL dialect or download diagrams as images and embeddable previews for documentation.
- **Auto-sync and versioning:** On Cloud plans, diagrams stay in sync with the live database automatically, with change logs and version history to track every schema drift.
- **Real-time collaboration:** Invite teammates to view and edit diagrams simultaneously, with multi-user workspaces and 2FA on team plans.

**Strengths:** Truly open source with a generous free self-hosted option and no database access needed; Fast setup — a single query gets you a complete interactive diagram in seconds; Broad DBMS coverage including PostgreSQL, MySQL, SQL Server, SQLite, ClickHouse, Snowflake, BigQuery, and Oracle; AI generation works both ways: prompt-to-diagram and diagram-to-DDL

**Limitations:** Cloud collaboration, auto-sync, and the AI assistant are paid; the free self-hosted tier limits you to two diagrams and ten tables each; Snowflake and BigQuery support sits on higher-tier plans; As a specialized ERD tool it does not replace a full data-governance or lineage platform

## GPTExcel

GPTExcel positions itself as more than a formula generator. The chat workspace ingests your Excel or CSV files and answers questions about them directly, finding trends and anomalies while explaining the reasoning. Alongside that, dedicated generators cover the tasks people actually repeat: writing and explaining formulas for Excel, Google Sheets, LibreOffice Calc and Airtable, generating SQL queries and regular expressions, producing VBA, Apps Script, LibreOffice Basic, Airtable and Python scripts, and cleaning or transforming messy data.

Two specialised agents stand out. The Pivot Builder produces native Excel pivot tables complete with slicers and pivot charts from a plain-English request, and the Slide Deck Builder converts a spreadsheet into a PowerPoint or PDF presentation or a written summary of its key figures. The site claims 1.7 million users, more than 60 million formulas generated and a 4.9/5 rating from roughly 938 reviews.

Security is a stated priority for a product handling sensitive financial data: AES-256 encryption at rest, TLS in transit, files never used as training data, GDPR-ready consent management, Google and Microsoft sign-in or passwordless magic links, and account plus files deleted together on request. Pricing is credit-based, with a genuinely usable free tier and two paid tiers for heavier usage.

**Pricing & Plans:** Freemium with annual billing offering around 30% off. The Free plan costs $0 forever and includes 50 credits a month, a fast model, 5 free tool runs per day, files up to 5 MB and 10 per chat. Pro is $9/month with roughly 3,000 credits a month and files up to 50 MB. Pro Plus is $18/month with roughly 10,000 credits a month, expert models and files up to 100 MB. Credit consumption varies by model (for example 1, 2 or 10 credits per message for fast, standard and expert models).

- **Chat with your spreadsheet:** Upload Excel or CSV files, or a photo of a table, and ask questions in plain English to get answers, charts and summaries.
- **Formula, SQL and regex generators:** Produce and explain formulas for Excel, Google Sheets, LibreOffice Calc and Airtable, plus SQL queries and regular expressions.
- **Native pivot table builder:** Create real Excel pivot tables with slicers and pivot charts from a written request rather than clicking through menus.
- **Script and automation generation:** Generate VBA, Google Apps Script, LibreOffice Basic, Airtable and Python scripts to automate repetitive spreadsheet work.
- **Slide decks and reports:** Turn a spreadsheet into a downloadable PowerPoint or PDF deck, or a written summary of its key figures.

**Strengths:** Free tier with 5 daily tool runs is genuinely usable before paying; Covers formulas, pivots, charts, SQL, regex, scripts and slide decks in one workspace; Explicit privacy commitments: no training on your files and deletion on request; Chat checks newly released Excel and Sheets functions against official documentation

**Limitations:** Credit allowances mean heavy chat users may hit limits even on paid plans; File size caps (5 MB free, up to 100 MB on Pro Plus) constrain very large workbooks; Best output quality and expert reasoning are locked behind the higher $18/month tier
