Five primary pen families
Ballpoint, fountain, pencil, brush and marker keep the main Ink Studio focused. Existing compatible highlighter and calligraphy strokes remain readable.
The complete KivoNote workspace
Everything you need to think on the page.
Precision ink, editable PDF tools, two-document study and local organization, designed for Android tablets and S Pen.
Ink and S Pen
Handwriting shaped around Android.
Write with the stylus while your finger scrolls and zooms. Hold the S Pen side button to erase, then release it to return to your previous tool.
Pressure and tilt
Stroke width, opacity and character can respond to how the stylus meets the screen.
Fountain control
Adjust nib angle and stabilization for cleaner flat-nib and calligraphic writing.
Deterministic width
Choose from twelve width steps, then keep favorite color and pen combinations in three persistent presets.
Custom color
Use the compact palette for quick choices or select a precise custom color for the page.
Palm rejection and hover
Stylus-only writing prevents finger marks while hover feedback helps position the pen before contact.
Ruler and smart shapes
Align marks, hold a stroke to straighten it and create clean geometric shapes without leaving the page.
Gesture editing
Scratch erase, circle select, undo and redo keep correction close to the writing action.
PDFs and pages
Annotate, navigate and organize every page.
Read and mark up PDFs in a continuous workspace, then use focused page tools without leaving the document.
Gapless vertical flow
Pages meet edge to edge so scrolling does not feel like jumping between separate cards.
Document-wide zoom
Pinch from 0.42× to 4× and the whole continuous document scales together.
Editable annotation layer
Ink, text, clips and images remain individually editable above the original page.
Dedicated Pages view
Open the right-side preview panel directly, filter All, Bookmarks or Notes, and tap a portrait preview to navigate.
Local search and bookmarks
Search PDF text, OCR content and annotations, then jump to a matching page or saved bookmark.
Complete page control
Add, duplicate, move, rename, rotate, crop, label or delete pages from contextual page actions.
PDF and PNG export
Export a page as PNG or a complete notebook as PDF. Untouched imported PDFs use a source-preserving fast path.
Resume exactly
Return to the page, zoom level and reading position where you left the notebook.
Qualification note: PDF rendering, edited export and resume behavior are still being validated on representative Samsung hardware before public release.
Text, selection and media
Edit content where it lives.
Tap the page to type, select handwriting or place an image. Each object stays editable on the page instead of being flattened into the background.
Tap anywhere
Type directly at the chosen page position. Empty editors disappear cleanly when you finish.
Direct manipulation
Move, resize from four corners, rotate or delete selected text and media.
Freeform clipping
Draw around an irregular region, place the clip elsewhere and retain a link back to its source page.
Rich text
Change font, size, color, alignment, bold, italic and underline after writing.
Lists and checklists
Create structured notes with bullets, numbered lists and tappable checklist items.
Spelling suggestions
Use Android writing suggestions while editing typed content.
Rectangle and freeform lasso
Select ink or page content with the shape that fits the material.
Image editing
Insert, crop, flip, lock, caption and change corner treatment without leaving the notebook.
Layer order
Bring an object forward or send it back when page elements overlap.
Cross-page transfer
Copy selected content to another page while preserving editable source data.
Return to source
Use a stable source link on a clipping to jump back to the original context.
Durable study objects
Sticky Notes, Code Blocks, offline LaTeX and Web Clip previews remain editable through save, copy, undo and archive restore.
Object security
Lock media against accidental movement while retaining later unlock, crop, caption, layer and transform controls.
Split workspace
Two complete documents at the same time.
Open the same notebook twice or pair two different notebooks. Each pane behaves as an independent continuous document.
Independent navigation
Separate page, scroll and zoom state for left and right panes.
Symmetric controls
Matching titles, close actions and navigation on both sides.
Active-pane previews
Page previews and page actions target the pane you are currently using.
Quick switching
Change the notebook in either pane without rebuilding the complete study layout.
Library and search
Organization that can grow with a semester.
Build a nested structure, protect private subjects and search beyond filenames to reach the exact page.
Library views
All NotesRecentsFavoritesUnfiledTrashSearch reaches
Titles and tagsPDF and OCR textTyped textCaptionsPage labelsNested folders
Create class and project structures with folder colors and emoji for quick visual recognition.
Device-credential locks
Protect a folder and inherit that protection across its child content.
List and grid
Switch between information-dense lists and cover-led grids, then sort the view.
Bulk actions
Select multiple notes to move, duplicate or place them in Trash together.
Covers and tags
Give each notebook a recognizable cover and searchable context.
On-device recognition
Index bundled Latin OCR and selected handwriting-to-text locally. Accuracy varies by writing and language.
Document scanner
Capture, crop, filter and combine multiple camera pages before adding them to a notebook.
Thirty-day Trash
Recover deleted notes during the retention window before automatic cleanup.
Paper and appearance
A workspace that fits the subject.
Choose the right page structure, then adapt the surrounding interface to the device and your preference.
Blank
Ruled
Grid
Dotted
Cornell
Planner
Study templates
Use Cornell, isometric, music, weekly planner, meeting, daily study, checklist, storyboard and engineering layouts.
Custom surfaces
Adjust page background, paper color and notebook cover without flattening your annotations.
Four interface themes
Choose System, Light, Dark or AMOLED for the surrounding workspace.
Vivid accents
Set a personal accent while controls maintain consistent contrast and state.
Toolbar control
Hide and reorder tools so the editor reflects your actual workflow.
Five interface languages
Use English, German, Turkish, Spanish or French, or follow the Android system language.
Focus and productivity
Useful study controls, kept in the right place.
Hide surrounding chrome when you need concentration, or bring in purpose-built tools for practice and presentation.
Focus Mode
Clear panels and secondary controls from the page when concentration matters.
Study Tape
Cover part of the page to practice recall without editing the source material.
Study Timer
Run a focused session with controls positioned above Android system insets.
Presentation Mode
Present the document with a cleaner reading surface and direct navigation.
Page-oriented Find
See bounded snippets, source labels and the exact page for each PDF, OCR, typed-text, caption or transcript match.
Hardware shortcuts
Use available keyboard and stylus actions without moving back through menus.
Fast notebook switching
Move between notebooks from the editor and split workspace.
Bookmarks
Mark important pages and filter the Pages view to reach them directly.
Audio notes
Keep the explanation beside the page.
Record a lecture or spoken thought while you continue reading and writing. Audio remains notebook data rather than a separate cloud service.
App-private recording
Capture AAC audio only after an explicit microphone action. KivoNote never asks for microphone permission at startup.
Playback on the page
Keep transport controls close to the active notebook while handwriting and scrolling remain available.
Editable transcript
Correct, extend or write a transcript manually and keep timed segments linked to the recording.
On-device recognition
Compatible Android 13+ devices can use an explicitly offline recognizer. Unsupported languages retain recording and manual editing without a network fallback.
Durable notebook data
Recording bytes, duration, transcript state and edits survive save, reopen, page copy and verified .kivonote archive restore.
Managed cleanup
Shared recording assets remain safe when a page is duplicated and are removed only after no notebook object references them.
Device note: Offline transcription availability depends on the Android device and installed offline language model. KivoNote does not silently send speech to an online recognizer.
Local reliability and access
Your work remains useful without a KivoNote account.
The first release keeps the core notebook local, saves page changes incrementally and avoids adding network services before they are ready.
KivoNote does not upload your note content in the offline release.
Read the Privacy PolicyPer-page local storage
SQLite page records save only the pages that changed, keeping edits efficient and recoverable.
Dirty-page autosave
Pause and Back operations persist the pages and metadata that actually changed.
Rotating recovery states
Five local recovery points support restoration after an editing problem.
App-private assets
Imported content and editable objects remain in the Android app's private storage unless you export them.
No ad or analytics SDK
The offline build does not require a KivoNote advertising identifier or analytics account.
Accessible actions
Core controls use labelled actions, tooltips and minimum 48 dp touch targets.
Motion preference
Short transitions respect Android's disabled-animation setting and do not block stylus input.
No AI or cloud dependency
Audio and transcripts stay local. Generative AI and cloud collaboration are deliberately outside the first public release.
Workspace resurrection
Primary and secondary notebook, page, scroll, zoom and active-pane state are recorded for recovery after Android reclaims the process.
Memory-aware rendering
Visible pages outrank thumbnails, oversized scans are bounded and speculative work is cancelled under Android memory pressure.
