User Manual
Everything you can do
with Docufy AI.
A quick reference for every feature in the app, what it costs in AI credits, and how the credit system works. If anything here is unclear, write to mail@alceitlabs.com.
Free — included for everyone
These work on the free tier with no subscription and no AI credits. No limits beyond the per-scan page cap.
Scan a document
Tap the blue + button on the document list. The ML Kit document scanner opens — point your phone at the page and the edges, perspective and contrast are detected automatically. Multiple pages can be added in one session. Free tier: up to 20 pages per scan; Premium: up to 30 pages per scan.
Generate a PDF
When the scan finishes, a clean A4 PDF is generated automatically — single- or multi-page, with the filename derived from the detected document type (lease, invoice, prescription, etc.). Stored encrypted on your device.
Share a PDF
Open any document → the share icon in the top bar → pick the app to share to (email, WhatsApp, Drive, Signal, anything that accepts a PDF). The file leaves your device only when you tap share.
Organise with folders
Long-press a document to move it into a folder, or create a new folder from the document list overflow menu. Folder structure is unlimited and free.
Import from gallery
Already photographed a document? On the scanner screen, tap "Gallery" instead of using the camera. Select your images in the right order — a numbered confirmation overlay guards against the Samsung One UI ordering bug.
The six AI workflows
Five of the six workflows below are unlocked by an active Premium subscription (Weekly or Monthly) or by boost credits alone — no subscription required. Translate is the exception: it needs an active Premium subscription. Each workflow runs once per (document, mode) combination and the result is cached — re-opening the screen is free and instant.
📝
Generate summary Premium
Four flavours: Short (3-line gist), Long (full prose), Bullets (key points), Explain (assumes you're new to the topic). Pick the one that fits — same credit cost.
✅
Build to-do list Premium
Pulls actionable tasks out of contracts, letters, meeting notes — "sign by", "pay by", "follow up on", "send to". Order preserved so you can work through them top-down.
🔑
Extract key facts Premium
Structured key/value list of the most important data points: numbers, dates, names, IDs, amounts. Useful for invoices, rental agreements, official letters.
⚠️
Analyse risks Premium
Flagged with severity (Critical · High · Medium · Low). Catches one-sided clauses, fee traps, short-notice deadlines, missing protections. Always cross-check against the original.
💬
Document chat Premium
Ask any question — the AI answers based only on the current document. Each message uses credits proportional to document size (see table). 500-character limit per question.
🌍
Translate Premium
51 languages including all 24 EU official languages plus Mandarin, Japanese, Hindi, Arabic, Swahili. Each language counts as a separate translation — cached after the first run.
Credits — how much each action costs
Every AI action consumes 1, 2 or 3 credits, depending on the size of the document it runs on. Bigger documents need more processing, so they cost more — but the price is capped at 3 credits even for a 30-page file.
| Document size |
Credits per action |
Bucket |
| 1 – 4 pages |
1 |
Small |
| 5 – 14 pages |
2 |
Medium |
| 15 – 30 pages |
3 |
Large |
Example: A 12-page lease costs 2 credits to summarise, 2 credits to extract key facts, 2 credits to analyse risks, and 2 credits per chat question. The result of each is cached — opening the summary screen a second time is free.

Premium Monthly · €9.99

Boost Packs
One-time purchases that top up your AI credits: +50 credits or +100 credits. Boost credits never expire and work without a subscription — a Free user can buy a pack and use the AI workflows it covers (summary, to-do, key facts, risks, chat). Your weekly/monthly plan credits are spent first, so a paid boost is only used once the plan pool is empty and never goes to waste. (Translate stays Premium-only.)
How spending works: When you trigger an AI action, your weekly/monthly plan credits are used first, then your boost credits — so the paid boost that never expires is preserved for as long as possible. The action only runs if the total available covers its cost — otherwise the paywall opens instead of charging a partial amount. Credits are only deducted when the AI action actually succeeds on our server.
Restoring purchases & boost
Your subscription
Subscriptions are tied to your Google account, not to one phone. On a new device or after a reinstall, sign in to Google Play with the same account — the app re-checks with Google on the next launch and re-activates Premium automatically. You can also force it any time via Paywall → "Restore purchases" (also reachable in Settings). If your plan has expired the app reflects that too: it switches back to Free instead of showing a stale Premium state.
Your boost credits
Boost packs are one-time (consumable) purchases, so Google cannot simply re-deliver them — but your remaining boost balance is kept safe on our server. After a reinstall on the same device and Google account it returns automatically (a single anonymous device key is included in Android app backup; your documents and scans are not). If you sign in with a Google account, your boost is additionally tied to that account and follows you to your other devices. Tap "Restore purchases" to pull the latest balance immediately. Boost works with or without a subscription.
Cloud sync — multi-device backup
Sign in with your Google account in Settings → Cloud sync → "Sign in". Once signed in (and Premium-active), open Settings → Cloud sync → "Configure" to pick which categories should sync: Document details · PDF files · Summaries · Key facts · Risks · Translations · Chat history. Chat history is off by default on privacy grounds — toggle it on if you want it backed up.
Cloud sync covers documents you scan after turning it on. Files scanned earlier remain on this device — Cloud sync does not reach back to upload your history. If you want a multi-device copy of an older paper original, simply re-scan it.
Deleting a document removes it from all your connected devices on their next sync — there is no separate cloud copy left behind. Deletion is permanent: there is no trash or undo, so the confirmation prompt is your last checkpoint.
If your subscription ends, cloud access is paused — your synced data is not reachable without an active Premium plan. It is kept safe for a 60-day grace period and is restored the moment you re-subscribe within that window. After the grace period it is deleted automatically.
Privacy & account controls
Change advertising consent
Settings → Legal → "Manage ad consent" re-opens the consent form (EU/UK/CH users). You can withdraw or change your ad personalisation choices at any time.
Delete your account and data
Settings → Account → "Delete account & data". This removes all your local and cloud data immediately and signs you out. There is no recovery — make sure you have exported anything you want to keep first.
Common questions
"I tapped an AI action but the paywall opened — why?"
Your available credits — your plan pool plus any boost — do not cover the action (1, 2 or 3 credits depending on document size). A Free user with no boost sees this on every AI action. Buy a boost pack (works without a subscription) or wait for the next reset. Note: Translate always needs an active Premium subscription — boost credits do not unlock it.
"Why is the second tap free?"
Every AI output is cached per (document, action). Re-opening a screen reads from cache — no credit charge, no network call. Editing or re-scanning the document invalidates the cache.
"Why does Translate ask which language every time?"
Each translation is cached per target language. The first translation into French costs credits; opening it again is free. Translating the same document into Spanish is a new action and costs credits again.
"My document is 45 pages — what happens?"
Premium tier caps a single scan at 30 pages — split larger documents into parts. Each part is then a separate document with its own credit cost based on its actual size.
