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.
