Workspace plans and metered usage
Notes and boards hold the app plan, and coding agents build it. AI top-ups start at five dollars, and external API keys are supported. Codespaces are billed by the hour while they run. Sign-up requires no card.

File storageNotes, PDFs and other workspace files sync across devices. AI runs and codespaces draw on credits, not storage.
Credits included10,000 credits is $1.00. Credits pay for AI runs, OCR and codespaces, at the rates on the model pricing page.
Note editor + calculatorThe editor supports Markdown and LaTeX and runs calculations inline, fully offline. No AI involved.
Tiled tabs, for any screenWindows split into tiles, with tabs arranged to fit the screen. Layouts can differ for vertical monitors and widescreens.
PDF to note (OCR)Turns a scanned PDF into an editable note with OCR. Formulas come out as LaTeX, tables and figures stay in place. After the scan, AI questions read the note instead of re-running OCR.
PDF editor (OCR)Edits run on the OCR text, so OCR is required. An AI agent applies one instruction to the whole PDF. For example: translate every page or fill a form.
