What Chartt is
Chartt is a web-based AI analyst for CSV, Excel, and plain text files. Users can ask questions in everyday language and receive charts, numbers, and explanations. The tool accepts CSV, XLSX, XLS, and plain text uploads, then infers column types, units, and date ranges. It can select bars, lines, tables, sparklines, or breakdowns to present an answer. Users can pin chart cards to dashboards that refresh when source files change. Chartt also says it can identify spikes, dips, and unexpected segments and summarize them in plain English. Shared chart, chat, and dashboard links are available, and answers link back to source rows or files. The maker says files and database contents are encrypted at rest, data is encrypted in transit, and employee access is limited. Relevant uploaded data may be sent to OpenAI and Google Gemini, but customer data is not used to train AI models. The free plan includes 100 credits a month and files under 100 MB; new queries pause when credits run out until the next billing cycle or an upgrade.

The full review of Chartt
Chartt is a web-based AI analyst for CSV, Excel, and plain-text files. It suits analysts, operations leads, and founders who need answers and shareable charts without SQL or a maintained BI stack. Its strongest case is fast, traceable exploration of files; credit quotas, source limits, and third-party AI processing make plan and data-policy decisions important.
Overview
Upload CSV, XLSX, XLS, or plain-text data and Chartt infers column types, units, and date ranges. You can ask questions in ordinary language and receive numbers, explanations, and a visualization selected for the question. Answers link to source rows or the source file, giving reviewers a way to check the basis of a result rather than accepting an opaque summary.
Chartt is designed around files rather than a large integration catalogue. Charts, chats, and dashboards can be shared by link. Pinning chart cards creates a dashboard whose layout remains live and refreshes when its source files change, which is useful for recurring operational views without maintaining a separate BI project. It is less suitable when your workflow depends on many connected business systems.
Key features
Natural-language analysis and visual choice
Chartt chooses among bars, lines, tables, sparklines, and breakdowns to fit a question. That removes the need to decide on a chart type before you know what the data says, while tables remain available when exact values matter. Automatic detection of spikes, dips, and unexpected segments adds a second pass over a dataset and explains the finding in plain English. These tools can shorten the route from a raw spreadsheet to an initial investigation, but they do not remove the need to check definitions and source quality.
Dashboards, sharing, and exports
Pinned cards and refreshable layouts are a practical middle ground between a one-off chart and a fully maintained BI dashboard. Shared links let colleagues view a chart, conversation, or dashboard, and source-row links support provenance when a conclusion is questioned. PNG and CSV exports are included on the Free and Starter plans; Pro and Max add all export types, including SVG.
Security and data handling
Chartt says stored files and database contents are encrypted at rest, traffic is encrypted in transit, employee access is limited, and dependencies receive regular audits and security updates. It also says relevant uploaded data may be sent to OpenAI and Google Gemini for analysis, while customer data is not used to train AI models. That arrangement may be acceptable for routine business files, but organizations with strict data-residency or third-party-processing rules should look elsewhere or obtain approval first.
Pricing
Chartt is freemium. New queries pause when credits are exhausted until the next billing cycle or an upgrade, so the monthly allowance is a functional limit rather than a soft guideline.
| Plan | Price and allowance | What you get |
|---|---|---|
| Free | free; 100 credits/month | Files under 100 MB, 1 data source, 30-day chat history, PNG and CSV export, preset themes |
| Starter | $7 a month, billed annually ($84/yr); 1,500 credits/month | Up to 2 data sources, extended storage, 90-day history, PNG and CSV export, preset themes, no watermark |
| Pro | $29 a month, billed annually ($348/yr); 8,000 credits/month | Up to 5 data sources, large storage, all export types, custom themes, long-term archiving, no watermark |
| Max | $109 a month, billed annually ($1,308/yr); 35,000 credits/month | Up to 10 data sources, large storage capacity, all output types, custom themes, long-term archiving, no watermark |
Free is appropriate for occasional, small-file questions, but 100 credits, one source, and a 30-day history constrain sustained use. Starter is the sensible step for a single analyst who needs more queries and two sources; annual billing is required for its advertised monthly rate. Pro targets heavier analysis, archiving, custom presentation, and SVG or other output needs. Max is for high-volume users managing up to ten sources, not for teams that need unlimited capacity. The published plans do not state seat counts, so collaborative access should be confirmed before purchase.
Platforms
Chartt runs on the web. It accepts CSV, XLSX, XLS, and plain-text imports, with a 100 MB maximum upload size. Team collaboration is supported through shared charts, chats, and dashboards rather than a separately described native desktop or mobile application.
Who it's for
Analysts, operations leads, and founders who repeatedly interrogate spreadsheets will get the most from natural-language questions, anomaly summaries, provenance links, and refreshable dashboards. It is a good fit when speed and explainable file-based results matter more than building a broad data model. It is a poor fit for very large files, workloads that exceed monthly credits, or organizations unwilling to send relevant data to external AI providers.
Pros and cons
- Pro: Plain-language questions produce numbers, explanations, and several chart forms without requiring SQL or pivot-table work.
- Pro: Source-row links and shared outputs make findings easier to verify and circulate.
- Pro: Refreshable dashboards turn uploaded files into repeatable views.
- Con: Queries stop at the credit limit until renewal or upgrade, which can interrupt active analysis.
- Con: Even Max is capped at ten data sources, limiting larger multi-source operations.
- Con: Relevant uploaded data may be processed by OpenAI and Google Gemini, a material consideration for sensitive information.

Verdict
Choose Chartt if you want quick, explainable answers from CSV, Excel, or text files, plus dashboards that refresh as those files change. The main reason to look elsewhere is scale or sensitivity: credit and source caps limit sustained workloads, and relevant data may be sent to external AI services.
