Jev Data Questions
Vite app that turns a small CSV into a presentation-ready dashboard by profiling every column, choosing the charts that fit the data and writing a headline per chart, with an optional Jev pass that reads each row for what the columns cannot answer on their own. The built-in demos run entirely in the browser.

About this project
Turn a small CSV into a presentation-ready dashboard. The app profiles every column, picks the charts that fit the data, and gives each one a headline that states what it shows. Optionally, Jev can then read every row for insights the columns cannot answer on their own.

Highlights
- Dropping a CSV always produces a dashboard: with no live backend the file is charted at /local, is never uploaded, and is cleared on reload.
- Questions the columns already answer, such as where squirrels are eating, are refused before any paid call is made.
- A stored dataset shows its observed dashboard first, and an explicit Analyze dataset action is what starts Jev analysis.
- DEMO_ONLY=1 builds the frontend without deploying Convex and disables live storage, intake and analysis even if credentials remain set.
Watch out
Stored uploads and results are public, so use non-sensitive data only. Intake is capped at 5 MB, 5,000 rows and 100 columns, and CSV URL fetches reject credentials and private or reserved destinations, validate every redirect, pin the connection to validated DNS answers, and enforce streamed size and timeout limits. The daily budgets are call counts rather than dollar limits: Jev accepts 1 to 5,000, OpenRouter 1 to 1,000, and a missing or invalid budget disables new paid calls entirely. Convex reserves permits atomically per provider and UTC day across concurrent instances, failed attempts still consume a permit, retries are counted, and SDK automatic retries are off. Cached drafts, joined runs, already-finished stored analyses and the local demos need no new permits, and saved live results stay readable once a budget is exhausted. Unit and Convex tests run against mock providers and storage, so they do not verify a provisioned production backend. The football dashboard is built from explicitly illustrative rules, not Jev predictions, and the demo labels keep observed values, illustrative calculations and live Jev output distinct. Copy reviewed against the repository README on 2026-10-04, not from running it.
Questions about this entry
Short answers drawn from the linked project or page.
No. A stored dataset shows its observed dashboard first, and pressing Analyze dataset is the explicit action that starts Jev analysis. Visiting datasets, demos or shared results never starts paid work. Without the live backend the file is charted in the browser at /local, is never uploaded, and disappears on reload.
Not safely. Stored uploads and results are public, and the README says to use non-sensitive data only. Intake refuses anything over 5 MB, 5,000 rows or 100 columns, and CSV URL fetches reject embedded credentials and private or reserved destinations while validating each redirect and pinning to validated DNS answers.
New paid calls stop, existing results do not break. Budgets count calls, not dollars, with Jev capped at 1 to 5,000 and OpenRouter at 1 to 1,000 per day, and Convex reserves permits atomically per provider and UTC day across concurrent instances. Failed attempts consume a permit and SDK automatic retries are disabled, while cached drafts, joined runs, finished analyses and the local demos need no new permits. Saved live results remain readable after the budget is gone.
Yes, in demo-only mode. Import it as a Vite project on Node 24 with DEMO_ONLY=1 and the checked-in build skips Convex, while the API runtime disables live storage, intake and analysis even if old credentials are still present; both local demos, CSV export and demo links work with no services or secrets. Going live needs the Convex and UploadThing integration, a V7 UploadThing token containing apiKey, appId and regions (a standalone raw key cannot upload), and npm run build:vercel needs CONVEX_DEPLOY_KEY and CONVEX_WRITE_SECRET. A frontend-only build cannot update live backend functions.
At most 5 MB, 5,000 rows, and 100 columns. Stored uploads and results are public, so use non-sensitive data only.
ANALYSIS_DAILY_CALL_BUDGET and ANALYSIS_DAILY_DRAFT_BUDGET, defaulting in the sample to 1000 and 100. Jev accepts 1 to 5,000 and OpenRouter 1 to 1,000, and missing or invalid budgets disable new paid calls.
No. Cached drafts, joined runs, completed snapshots, and local demos need no new permits, and existing saved live results stay readable when a budget is exhausted.
