From a source page to a durable learning project.

Product principle

Keep the source in view.

The app is a source-centered workspace for learning and editorial review. It keeps the photographed page, editable OCR, translation history, references, study tools, and exports together. AI output is a first pass to inspect, not an authoritative interpretation.

The loop

Nine steps from scan to study.

1. Create one clearly named project for a work, class, or research goal.
2. Choose Managed AI or bring your own provider key. This choice affects the action you start; it does not convert or lock the project.
3. Add a camera image, photo, file, or selected PDF pages.
4. Crop, rotate, and confirm that the entire source is legible.
5. Choose output language, template, and quality. In the bring-your-own-key lane, also choose the provider and model.
6. Review the Managed AI disclosure and expected and maximum credits, or review the selected provider's own billing terms, before translating one representative page.
7. Review image, source text, identity, references, and translation together.
8. Use Word Lens, Reader, notes, review items, summaries, or project-grounded tutoring.
9. Export a content-specific document and protect the project with backup.

Two independent lanes

Choose per action; keep ownership of your projects.

Managed AI onboarding

Create a separate managed account only when you want it.

1. Select Managed AI — no API key needed during setup or open the Managed AI screen later.
2. Confirm that the account holder is at least 13 years old. Managed accounts for children under 13 are not supported.
3. Verify one canonical email address with the short-lived code sent to that address. The app stores rotating managed-session credentials in platform secure storage.
4. Review the authoritative plan, merchant, available balance, grant breakdown, expiration dates, and feature availability.
5. Choose a specific managed action. Account creation alone does not upload a project or start provider work.

Commercial identity is separate from Global Library contributor identity unless you explicitly link them. Signing out or deleting the managed account does not delete local projects, provider keys, backups, or exports.

Confirm one customer action

See the data and maximum charge before managed work begins.

Before every paid action, the app identifies the feature, describes what data will leave the device, shows the expected and maximum credits, shows the current balance, and states whether optional repair or enrichment is included. One confirmation covers the action's internal segments and retries; those attempts are not separate customer charges. The final charge cannot exceed the confirmed maximum.

A failed, malformed, unsafe, or unusable managed result costs zero credits. Provider retries are absorbed by the service. A completed and validated result retained briefly for replay can be charged even if the device disconnects before receiving it; reopen the action instead of starting a duplicate.

Prepare the source

Import cleanly, then verify identity.

Use sharp, evenly lit pages with complete margins. For large PDFs, preview and select the needed range. The app keeps the original and edited image, while OCR text remains correctable.

Authenticated result

Compare the source and translation side by side.

The illustrated test used the production bring-your-own-key image-import and translation path with Gemini. The completed translation was saved and reopened in Parallel bilingual view. Managed results use the same source-centered review surface when that lane is available. Translation history remains distinct when the lane, provider, model, template, OCR, or image changes.

Before marking a page finished

• Confirm page and volume labels against explicit evidence.
• Check paragraph order, headings, names, quotations, and bottom-of-page text.
• Make explanatory additions and transliterations distinguishable from source wording.
• Open source references and verify the cited location.
• Correct OCR or identity first, then choose Re-translate when the input was wrong.

Educational use

Turn a result into a learning loop.

Word Lens, Reader Mode, speech, summaries, tags, notes, and review items help the learner return to the text. The tutor is most valuable for a focused request grounded in the open project: simplify a paragraph, compare two concepts, point to support on the page, or give a short comprehension check.

Know what leaves the device

Cost, privacy, balance, and retention.

Plans, restore, and account control

Purchase and manage with the merchant for the installed app.

The US launch has a $12.99 monthly plan with 2,000 credits per paid month, a $139.99 annual plan with twelve monthly 2,000-credit tranches, and optional $4.99/500-credit or $14.99/2,000-credit packs. Prices are before tax; the checkout shown by the merchant is authoritative. Credit packs may be bought only while a managed subscription is active, but unused purchased pack credits remain after cancellation.

A restored purchase attaches to the verified managed account and shared wallet after the backend validates merchant ownership. Do not buy overlapping subscriptions from two merchants. If the service detects more than one, already-paid grants remain auditable, but further purchases are blocked until the conflict is resolved.

Delete the managed account

Delete immediately from the Managed AI screen or use the public account-deletion page after recent email verification. Deletion stops managed access, revokes sessions, removes temporary AI content, and anonymizes the account while retaining only pseudonymous records required for accounting, fraud, ownership, and refunds. It does not delete local projects or your own provider keys.

Output and durability

Export for the next task, then back up.

Reader PDF and Study Reader PDF support reading and learning. Markdown and DOCX support editing. ZIP protects a portable project copy. XLIFF, TMX, CSV, and comparison outputs support specialist workflows where available.

• Export names use the project and content identity instead of a generic filename.
• Preview title, page order, Hebrew direction, images, and footnotes before distribution.
• Configure backup after the first meaningful project. Reinstalling the app is not a backup strategy.

Gemini Notebook / NotebookLM

Build accurate advertising and how-to videos from product truth.

The source pack separates demonstrated capabilities, educational story, privacy and cost disclosures, allowed claims, forbidden claims, a 60-second shot list, tutorial structure, and prompts for Explainer, Short, Cinematic, Audio, and presenter-deck artifacts.

Evidence

How this walkthrough was verified.

1. A disposable iPad simulator ran version 1.0.6 (98).
2. A temporary Gemini credential was stored through the app's secure credential service.
3. The production import service added an original Hebrew sample image.
4. The page received verified source text and explicit printed-page metadata.
5. The production translation service called gemini-3.1-flash-lite.
6. The app verified and persisted a completed Gemini translation.
7. The real library, project, page, consent, and masked settings screens were captured.

The credential is not present in the repository, screenshots, public guide, or downloadable documents. Provider model availability and behavior can change after the test date.
