Otsimo

Game-based early learning, speech therapy and AAC for young children with autism and Down syndrome

Otsimo turns any phone or tablet into an adaptive, ad-free early learning programme for children with autism, Down syndrome and speech delays: 100+ skill-building games, voice-recognition speech practice and an AAC communication tool, used at home or alongside therapists.

About the innovation

Democratizing the special education

"We believe that education is a basic human right and are determined to improve our work until proper special education is available and accessible to each and every household in need."
- Zafer Elcik, Co-founder of Otsimo, Ashoka Fellow, from his TEDx Talk

Read Zafer's story:

Zafer's Brother Alper
Meeting With Autism
My brother was diagnosed with severe autism when he was 2 years old. I was 10 back then. He had been non-verbal and unable to read for a long time. I remember those days when we wanted him to speak a word.

Alper & Zafer
Discovering the potential
He was having a hard time focusing and learning. But when I bought my first smartphone, I realized my brother has a special interest in smart devices, about 10 times longer than his usual attention to his surroundings. After that, I bought him an iPad as a gift.


Lack of a proper solution
Then I noticed a problem. There weren’t suitably designed applications for children with disabilities like his. Some apps were too expensive, and the games were very difficult for him. Because of that, he could play only a few apps, some of which included ads that can be harmful to him.

Zafer & Sercan(cofounder)
...and taking the initiative
So with my close friend, we decided to build a basic color game to teach colors to my brother. In a relatively short period of time, he became able to distinguish the colors. His interest and success inspired us to build games for every child who can benefit from them, and we created Otsimo, a mobile education platform for children with disabilities.

Our Apps:

Otsimo Special Educationis uniquely democratizing access to special education internationally with a direct-to-family approach that is affordable, accessible, efficient, and, best of all, simple. Designed to empower and engage children with developmental disabilities—such as autism, down syndrome, and other cognitive learning disorders—Otsimo enables any mobile device to become a platform for learning. The app allows children with special needs to develop core cognitive, social, and speech skills through gamification.

Created under the guidance of parents, psychologists, and special education teachers; assistive games in Otsimo aim to teach fundamental education about core skills such as words, alphabet, numbers, emotions, colors, animals, and vehicles through assistive matching, drawing, choosing, ordering and sound games. For individuals or children having speech problems, Otsimo has a new and improved AAC (Augmented and Alternative Communication) module, a tool often used in speech therapy, autism communication, or special education schools. If you want your nonverbal relative/student with autism or neurodevelopmental disorders, free AAC is a proven effective learning tool to have a better speech and to communicate better.

Otsimo Speech Therapyis a voice-controlled and video modeling-based language and speech therapy app. Individuals with speech delays, stuttering, apraxia, non-verbal autism, articulation problems, aphasia, and late talkers can easily use the app for their language and speech development.

In each category, relevant words are spoken on the screen in a systematic way to stimulate sound production. Funny face mask rewards at the end of the sessions boost the speech therapy efforts while keeping the individual entertained. Moreover, there are plenty of stickers dedicated to each exercise activity to be collected once the session is completed. Voice outputs from the individuals are evaluated anonymously by a machine learning environment within the app to provide a better and unique speech exercise experience.

Otsimo AACOtsimo AAC | Tap and Talk is a symbol-based augmentative and alternative communication (AAC) app that gives a voice to non-speaking children and adults, including individuals with autism, Down syndrome, cerebral palsy and other speech and language disorders. Users tap picture symbols or type on the built-in keyboard, and the app speaks their message aloud.

The app comes with more than 1,700 preinstalled words and 13 voice options. Families and therapists can customize every screen in edit mode by adding cards, words, phrases, photos and symbols, and verb conjugation lets users go beyond single words to talk about the past, present and future. Otsimo AAC works without an internet connection, so communication is always available at home, at school and on the go.

Controlled study: Otsimo Speech Therapy improves language in autistic children. In Jordan, 20 autistic children aged 4-8 used the app alongside routine therapy and were compared with a matched control group. The Otsimo group scored significantly higher in receptive, expressive and pragmatic language (p<.001). North American Journal of Psychology, 2026: https://doi.org/10.65696/001c.162132

University of Granada experts rated 155 autism apps on Google Play. Only 14 were 'highly recommendable'; Otsimo had the joint-highest score (40/46) and the top content score (Technology in Society, 2021). It also shared the top score among 88 apps for early academic skills (Mathematics, 2021). https://doi.org/10.1016/j.techsoc.2020.101474 https://doi.org/10.3390/math9091032

Early writing gains: in a single-case study at Universitas Negeri Surabaya (Indonesia), a 7-year-old autistic boy practised letter tracing with Otsimo. His early-writing score rose from 20-30% to 85% and stayed at 88-90% after the app was withdrawn. Didaktika: Jurnal Kependidikan, 2026: https://doi.org/10.58230/27454312.3911

Rated 'excellent' for usability: at the 4th Eurasian Conference on Human-Computer Interaction (Baku, 2025), researchers tested three popular learning apps for neurodivergent children with expert heuristics and parent SUS ratings. Otsimo was the only app rated 'excellent' (81.25%), versus 59.38% and 43.44% for the other two.

Otsimo is one of eight case studies in IEEE Standards Association's 'Applied Case Studies for Designing Trustworthy Experiences for Children' (2022), alongside The LEGO Group. Prepared with the BILGI IT Law Institute, it shows how Otsimo designs for children with special needs: no ads, calm colours, optional sounds and parental gates.

Used by teachers and families: Otsimo is among the apps reported by 251 early-childhood teachers of autistic children in Spain (Pixel-Bit, 2025), used by special education teachers in Turkey (Kastamonu Education Journal, 2026), rated important by 96% of 25 surveyed teachers in Ecuador (Ciencia Latina, 2024), and used by Turkish families during COVID-19 closures.

Research-informed design: Otsimo's team and a Koç University researcher analysed anonymised data from Otsimo's Turkish AAC module (about 500 core words) to find which words autistic children use most. Published in Eğitim Teknolojisi Kuram ve Uygulama (2019), the study offers guidance for building AAC vocabularies that match children's everyday needs.

Implementation steps

Download the apps
Install Otsimo Special Education, Otsimo Speech Therapy or Otsimo AAC for free from the App Store or Google Play on a phone or tablet. No special equipment or internet connection is needed during play.
Create your child's profile
In the parent section, enter your child's age and details so Otsimo can tailor the starting level and learning path. Therapists or teachers can help you choose which skills to focus on first.
Play short daily sessions
Let your child play a few short sessions every day at home. The games need no reading, contain no ads and adjust in difficulty as your child progresses. Sit with younger children at first and praise their efforts.
Follow your child's progress
Check the progress reports in the parent section to see which skills are improving and where your child needs more practice, then adjust the settings or goals together with your child's therapist or teacher.
Bring communication into daily life
For children who are not yet speaking, use Otsimo AAC during meals, play and daily routines so they can express their needs. Share what works with your child's therapist or teacher to connect learning at home with therapy and school.
