Hi Product Hunt! I’m building Deckumi for learners who want to turn study material into active recall practice.
CHECK → EDIT → REVIEW
Bring a PDF or notes, generate cards, check their source references, and edit the wording. Then recall, reveal, and rate each answer; FSRS schedules your next review. You can also import existing decks.
A SMALL WORKED EXAMPLE (authored demo, not a measured AI result)
Source: plants use light to convert water and carbon dioxide into glucose, storing chemical energy and releasing oxygen.
Card: “What type of energy does photosynthesis store?” → “Chemical energy, stored in glucose.”
Refine it to “In photosynthesis, what stores the chemical energy?” → “Glucose.” Check the source, then rate your recall. FSRS schedules the real next review after you study.

LAUNCH GIFT — 50 single-use codes
Each grants 30 days of Plus + 50 AI generation credits. Flashcards are available now; other study formats are coming soon.
QUICK FAQ
• Redeem: sign in, open Account & credits → Redeem code, check one code, then confirm. Previewing a code does not use it.
• Eligibility: one promotional claim per account; accounts with an active paid membership cannot claim. Each code works once.
• Expiry: membership and gift credits both last 30 days from redemption. Claim before Dec 1, 2026, 23:59 UTC (Dec 2, 07:59 Beijing time).
• Billing: no payment card is needed to redeem. This gift expires without automatic charges and does not create a recurring subscription.
• Credits: this campaign includes 50 credits, not the paid Plus plan’s 300 monthly credits. AI generation uses credits according to actual usage; there is no guaranteed card count.
• Free use: create, organize, and review your own flashcards without a subscription. Paid AI generation credits are separate.
