Chartt vs Loam

Chartt is a web-based AI analyst for CSV, Excel, and plain-text files. Upload a file and ask questions in plain language; Chartt infers column types, units, and date ranges, then selects charts, tables, sparklines, or breakdowns to present answers with numbers and explanations. Chart cards can be pinned to dashboards that refresh when source files change. The service also surfaces spikes, dips, and unexpected segments with summaries, and shared chart, chat, or dashboard links can point readers back to source rows or files.

Chartt offers a free plan with 100 credits per month, one data source, files under 100 MB, and 30-day chat history. Paid plans start at $7 a month, billed annually at $84/year. The maker says files and database contents are encrypted at rest, data is encrypted in transit, and customer data is not used to train AI models; relevant uploads may be sent to OpenAI and Google Gemini for analysis. Queries pause when credits run out until the next billing cycle or plan upgrade.

Loam stores supported files and connected business data so authorized AI tools can query it and ground answers in rows. It accepts formats including CSV, Excel, Parquet, TSV, and JSON, and connects to tools such as ChatGPT, Claude, and Cursor through an MCP-compatible setup. The service is aimed at teams without a dedicated data team, including sales and marketing groups and company founders. Queries use the connected Loam account’s current access, and table permissions are checked when each request runs. Users can limit an AI’s access to selected data, such as allowing revenue while excluding payroll. Loam says uploaded and connected data is not used to train AI models and can be deleted by users; providers such as Google, OpenAI, and Anthropic process data to generate results and do not use it to train their models. The web upload interface accepts files up to 100 MB. The free Individual plan supports one person, file uploads, grounded questions, and supported AI connections. Individual Pro costs $399 a year, with a 39 USD monthly option; Team costs $499 a year, with a two-seat minimum and a 49 USD per-seat monthly option. The terms prohibit storing protected health information, primary cardholder information, or other sensitive information.
