One-time token packs
Add extra AI capacity without starting a subscription.
Every pack supports the same AI features; only the token amount changes. Flowing uses your monthly allowance first, then continues from your prepaid balance.
Use these tokens across:
- High-relevance keyword recall with snippet cards that open the original PDF
- Ask with your draft and selected sources as context
- Evidence-backed academic polish
- Continue writing from your manuscript and library evidence
Choose a token amount
Recall scans are generally lighter and cached. The ranges below assume the balance is used only for that feature, with a typical paragraph and 3–5 text sources; images, longer context, deep polish, and retries use more.
