Lignis is a writing assistant built specifically for people with learning differences (dysgraphia and dyslexia) that make it hard to learn to spell. We believe everyone has great ideas that deserve to be written down, even when the mechanics of writing and spelling get in the way.

What is dysgraphia? Dysgraphia is a brain difference in some people that makes it very hard to learn handwriting and spelling. It often occurs with Dyslexia but can occur by itself. Dysgraphic students often face challenges with spelling.

Lignis is built on top of typing as a key skill for people with dysgraphia. While speech-to-text is a powerful and empowering tool as well, typing unlocks additional opportunities.

Our Mission

Dysgraphia makes the physical and cognitive act of writing difficult. People with dysgraphia often know exactly what they want to say, but struggle to get the words onto the page correctly.

Research in cognitive science shows why this happens: spelling and thinking compete for the same limited working memory. When a student has to wrestle with spelling while writing, the mental space needed for ideas, argumentation, and organization gets crowded out. Studies show that transcription demands can account for up to 66% of the variance in writing fluency, and that when struggling writers dictate instead of type, they produce up to four times more text. The ideas were always there. Spelling was taking the space they needed.

Over time, many students stop reaching for the words they actually want to use. They substitute simpler words they know they can spell, and their writing ends up hiding the depth of what they really think.

Traditional grammar and spell check tools can get confused by dysgraphic spelling, which can often differ greatly from the correct spelling. Worse, standard spell checkers fail these students both ways: they flag nearly every word, creating anxiety and distraction, while missing errors that happen to be real words. For students with learning differences, traditional tools leave most flagged errors unresolved even after pointing them out.

Lignis takes a different approach. It uses AI to understand what was meant and allows a student to practice the correct spelling of each word, creating learning opportunities rather than roadblocks.

How It Works

• Write Freely First. Five decades of writing research confirms that separating writing from editing produces better results. Lignis lets students get their ideas down without red squiggles or auto-correct interrupting mid-sentence. The spelling gets corrected afterward, but the ideas come first.
• Smart Spell Checking. The AI figures out the intended meaning and offers the right word, even when the spelling is far off from conventional dictionaries.
• Personalized Learning. Lignis remembers the words needing practice and creates targeted practice through fun, unique, story-based exercises rather than simple drills.

Who We Are

Lignis is built by people who know how hard it can be to learn to write with extreme dysgraphia. We are a small team passionate about making technology that helps everyone with dysgraphia be more creative while also scaffolding spelling practice. We work closely with parents, educators, and specialists to ensure Lignis meets the real needs of children with dysgraphia.
