Nebo

Handwriting recognition on tablets has been a broken promise for the better part of two decades. Every stylus launch since the original Palm Pilot came wrapped in the same pitch: write naturally, and the machine will understand you. It rarely did. Nebo, built by the French firm MyScript and sometimes shipped under the name MyScript Notes, is the app that finally makes good on it.

MyScript isn’t a newcomer chasing a trend. The company has spent years licensing its Interactive Ink engine to hardware makers and rival note apps — the same recognition tech quietly powering features elsewhere. Nebo is MyScript flexing its own muscle, a first-party showcase for the best handwriting-to-text conversion in the business. That pedigree shows. Where competitors treat text recognition as a bolted-on afterthought, here it’s the entire architecture.

The positioning is deliberately premium. This is not a free-form sketch pad chasing the doodle crowd, nor a minimalist Markdown editor. Nebo targets the student taking lecture notes, the professional marking up contracts, the engineer sketching equations that need to become real LaTeX. It plants itself squarely against Notability, GoodNotes, and OneNote — apps that render handwriting beautifully but largely leave it as a static image. Nebo’s bet is different: ink should be live. Editable. Convertible. Searchable across 60+ languages.

The app spans iPadOS, Android, and Windows, with cloud sync stitching them together. It leans hard into stylus-first interaction — Apple Pencil, S Pen, Surface Pen — and it is honest about that focus. Use it with a finger and the point is missed entirely. Four distinct document formats — Notebooks, Boards, responsive Documents, and PDF markup — cover the full arc from messy brainstorm to polished export. It’s an ambitious spread, and mostly it earns the ambition.

• Interactive Ink Recognition: MyScript’s flagship engine converts print and cursive into typed text in real time, across 60+ languages, with class-leading accuracy.
• Math & Diagram Conversion: Handwritten equations become editable LaTeX; rough shapes snap into clean geometric figures. A genuine gift for STEM users.
• Gesture Editing: Scratch out a word to delete it. Draw a line to break a paragraph. The ink itself is the interface — no menu-diving required.
• Four Document Formats: Structured Notebooks, infinite-canvas Boards, reflowing Documents, and a dedicated PDF annotation mode.
• Generative AI Tools: Summarize a page, define a technical term, or auto-generate a practice quiz straight from notes.
• Cross-Platform Sync: Cloud sync across iPadOS, Android, and Windows.

The Core Loop

Everything Nebo does well flows from one interaction: you write, and the app understands. That sounds trivial. It is not. The recognition is built for low latency — words resolve almost as fast as they’re formed, and the engine is designed to handle everything from careful print to hurried cursive. Toggle conversion, and a page of handwriting snaps into crisp typed text you can copy, search, or export. This is the feature. Everything else orbits it.

What elevates Nebo above a clever party trick is the gesture system. Scratch out a word and it vanishes — no eraser tool, no selection box. Draw a vertical stroke to split text, a horizontal one to join it. These aren’t gimmicks; they’re the connective tissue that makes editing handwritten notes feel less like fighting a PDF and more like manipulating living text. The learning curve is real but short, and the gesture set is small enough that commands can plausibly become reflexes rather than things to memorize. That’s the mark of good interaction design.

The Four Formats

Nebo’s decision to ship four document types is both its greatest strength and its clearest source of onboarding friction. Notebooks are the workhorse: structured, paginated, ideal for sequential lecture or meeting notes. Boards throw out the page entirely — an infinite canvas for mind-mapping and messy ideation. Documents are the clever middle ground, where converted text reflows to fit any screen size or orientation, behaving like a real word processor rather than a fixed image. And the PDF markup mode handles annotation duty, letting you scribble across imported documents and — crucially — convert those margin notes to text too.

The problem is that a newcomer opening Nebo for the first time faces a choice they don’t yet have the vocabulary to make. Which format? For what? The app doesn’t hold your hand through that decision as gracefully as it should. Once the model is internalized, the flexibility is liberating. Getting there takes patience most productivity apps don’t demand.

The AI Layer

Then there’s the generative AI bolt-on: page summaries, term definitions, auto-built quizzes. This is where skepticism is warranted. These tools are competent and occasionally genuinely useful — a student cramming from a semester of notes will appreciate the auto-generated quiz. But they feel reactive, a checkbox ticked because 2025 demanded every app grow an AI feature. The summaries are serviceable, not revelatory. The quizzes lean toward surface-level recall. None of it approaches the polish of the core recognition engine, and none of it is why anyone should choose Nebo. Treat these as a pleasant bonus, not a reason to buy.

Where It Stumbles

The friction is real. Cloud sync, per user reports, can lag — a delay of seconds to minutes before a note appears on a second device, occasionally long enough to raise doubts about whether it synced at all. And those infinite Boards, glorious in concept, are built for a scale they can’t always sustain: a canvas that grows genuinely enormous invites minor performance hitches and bugs. Neither flaw is fatal. Both nag.

Aesthetically, Nebo is restrained to the point of austerity. The interface gets out of the way — clean typography, muted chrome, a canvas that foregrounds your content rather than the app’s personality. Some will find it clinical next to the warm, paper-textured skeuomorphism of GoodNotes. It’s an appropriate choice. This is a tool for thinking, not for admiring.

By design, this is a light, efficient app: real-time handwriting conversion of this scope is well within reach of capable hardware, and the recognition engine is engineered so that latency stays low under sustained writing. The exceptions are the ones already named: sprawling Boards, which push the canvas model past what it was built for, and the occasional sync stall. On a modern iPad Pro or a high-end Android tablet, the design should have headroom to spare; on older or underpowered hardware, the massive-canvas strain becomes more of a factor.

Nebo lives and dies by the stylus, and the platform experience reflects that. On iPadOS paired with an Apple Pencil, it’s arguably at its best — palm rejection is baked into the design, and the hardware-software handshake is clearly tuned for it. This is the reference implementation.

On Android, the story is more variable, because Android tablet hardware is more variable. On a Samsung Galaxy Tab with an S Pen, the design promises parity with the iPad experience. On lesser tablets with cheaper digitizers, results genuinely depend on the pen. The app is excellent; it can only be as good as the stylus feeding it.

On both platforms, the message is identical: finger input is a compromise you shouldn’t make. Nebo without an active stylus is a sports car in a parking lot. Bring the pen, or don’t bother.

Nebo does the hardest thing in its category better than nearly anything else available. The Interactive Ink engine is the rare feature that delivers on a decades-old promise the whole industry kept fumbling. If your work involves turning handwriting into usable digital text — especially math, especially across languages — nothing else on a tablet competes at this level.

The rough edges are real and worth naming: laggy sync, a learning curve born of too many format choices, strained performance on giant canvases, and AI features that feel obligatory rather than inspired. But these are the reservations attached to a very good app, not excuses for a mediocre one. The foundation is rock-solid, and we recommend it clearly to anyone with a stylus and a note-taking habit. Learn the gestures, and Nebo becomes the note app you stop thinking about — because it just works. That’s high praise for a productivity tool, and the reason it earns a strong recommendation despite the reservations.
