ChartAI vs Graph Maker

ChartAI

The pricing is the clearest thing about it: $5 once for 25 diagrams that never expire, or $24 a month for unlimited use, with Mermaid output you can keep and edit elsewhere. Against that, the app is a lightly reskinned chat client with ad-network tags on the page, and the vendor's country and support arrangements are barely documented.

Pros

• +One credit equals one diagram, and one-time credits never expire
• +Pro removes the per-diagram meter for $24 a month
• +Renders Mermaid, so output can be exported and edited as text
• +PNG and SVG export with in-place edits and colour themes

Cons

• −The interface is a generic chat client shell with little diagram-specific tooling
• −The page carries ad-network tags, which is unusual for a paid product
• −No company address or country disclosed - only an Inc. name in the footer
• −No public API, collaboration features or version history found

Graph Maker

Graph Maker is a quick way to turn a spreadsheet into a labeled chart without opening Excel, and it works well for a single ad hoc chart. It reads like a side project rather than an actively maintained product — the pricing page 404s, the bare apex domain serves an expired certificate, and the update its own creators talk about publicly dates to 2023.

Pros

• +Accepts plain-language chart requests instead of manual chart configuration
• +Reads CSV and Google Sheets directly
• +States it does not retain uploaded data
• +Free tier needs no signup friction beyond the basic flow

Cons

• −No pricing page is published; the $15/month Pro price appears only in the in-app upgrade dialog
• −The www subdomain works but the bare apex domain fails on an expired TLS certificate
• −Reads as a side project with no recent public update
