## AI2SQL

AI2SQL is an AI SQL query builder aimed at engineers, analysts and learners who work with databases every day. Instead of guessing at table names, you connect a read-only account and the tool builds a semantic layer from your actual schema, so the joins, columns and dialect match the database you picked. Supported engines include PostgreSQL, MySQL, SQL Server, Oracle, Snowflake, BigQuery, Redshift, MongoDB, SQLite and Firebird.

The workflow covers the whole life of a query. You describe the result you want in English (or another language) and get SQL back; you can paste a query you inherited and get a clause-by-clause explanation, ask for a rewrite with reasoning when something is slow, have broken SQL repaired with an account of what went wrong, and reformat anything before it hits a pull request. Finally you run it against a live read-only connection and read the returned rows without leaving the page.

Beyond the web app, AI2SQL ships an MCP server so clients such as Claude, ChatGPT in developer mode and Cursor can call your database from the chat window, a desktop Connector for Windows and macOS that reaches localhost or internal hosts, and a gateway that gives a team's agents one governed, audited, metered endpoint. Safety features include read-only credentials by default and a sqlGuard layer that blocks writes, DDL and multi-statement input. A free plan and a 7-day trial on paid plans lower the entry cost; the vendor requires a card to start the trial.

**Pricing & Plans:** Freemium model. A free plan starts you off with a demo database; paid plans include a 7-day free trial that requires a card but charges nothing up front, with cancellation in one click. Higher tiers add the desktop Connector and more usage. Check the site for current prices.

- **Text to SQL on your schema:** Describe the result you want in plain English or another language and get SQL written with your real table and column names in the dialect of your chosen database.
- **Explain, Fix, Optimize and Format:** Paste any query — generated or hand-written — to get a clause-by-clause explanation, corrections with reasoning, performance rewrites and clean formatting.
- **Run read-only against live data:** Execute queries against a connected read-only connection and inspect the returned rows and timing directly in the interface.
- **MCP and REST for AI agents:** Expose your database to Claude, ChatGPT in developer mode, Cursor or your own agent through a governed MCP endpoint and a REST API with per-agent keys.
- **Broad database connector set:** Works with PostgreSQL, MySQL, SQL Server, Oracle, Snowflake, BigQuery, Amazon Redshift, MongoDB, SQLite and Firebird.

**Strengths:** Generates SQL from your live schema instead of a generic example, so names and joins actually match your data; Combines generation, explanation, debugging, optimization and execution in one workspace; Read-only credentials and a sqlGuard layer that blocks writes and DDL reduce the blast radius of mistakes; MCP and REST endpoints let the same connection power Claude, Cursor, ChatGPT or a custom agent

**Limitations:** The 7-day trial still asks for a card up front even though no money is charged today; Query generation depends on a connection to the vendor's API, so it is not a fully offline tool

## Readray (formerly Lilys AI)

Readray is the current name of the product that launched as Lilys AI. The website lilys.ai now redirects to readray.ai, where the same team ships a reading assistant built around a single idea: instead of you pasting text into a chat window, the tool reads whatever is on your screen with you and proactively surfaces what matters.

Source parsing is the core differentiator. Videos are analyzed down to individual scenes so on-screen slides and charts are captured as frames rather than lost to a transcript, and figures, tables, and equations inside papers are read with their layout intact. Every line of generated output carries a citation that jumps back to the original passage, so you can verify rather than trust.

The product ships as a Chrome extension, a Mac and Windows desktop app, an iOS and Android app, and an MCP server that connects your source library to ChatGPT, Claude, Gemini, and other assistants. Reports come in a short Key Points format or a longer Deep Research format depending on how much depth you need.

**Pricing & Plans:** Free to start, with paid plans for higher usage and team features; check the official pricing page for current tiers.

- **Scene-aware video parsing:** Videos are analyzed scene by scene, capturing frames of slides, charts, and code shown on screen — not just the spoken transcript.
- **Layout-preserving document reading:** Figures, tables, and equations in research papers and PDFs are parsed with their original structure so summaries reflect the real content.
- **Line-level citations:** Each line of AI output links to the exact source passage; clicking it jumps the viewer straight to that spot in the original.
- **Library synced over MCP:** Sources you read become a personal library that Claude, ChatGPT, Gemini and other MCP-compatible tools can query directly.
- **Agent with skills and memory:** An assistant that summarises, compares research gaps, sorts your library into folders, and remembers context across sessions.

**Strengths:** Parses videos scene by scene, so visuals and slides survive summarization; Every claim links back to a precise citation you can verify in one click; Works across extension, desktop, mobile, and an MCP server for other AI tools; Handles papers, PDFs, web pages, and videos in one consistent workflow

**Limitations:** The recent rebrand from Lilys AI means older guides and links may still use the previous name; Best value depends on living inside the extension or desktop app rather than the web alone
