Jellow

Jellow is a suite of AAC tools that uses symbols, text and speech to support communication. It is best suited to children and early learners who need a broad multilingual vocabulary, though its adult-focused Plus option has a narrower language range.

Its strongest case is the combination of offline use, switch access and several purpose-built tools; the main caveat is that the suite’s features and language coverage vary by product.

Overview

Jellow spans communication boards for children and adults, tools for people with sudden speech or hearing loss, and speech-to-text and text-to-speech functions. It pairs a hybrid symbol system with spoken output and supports touch, keyboard and external switches. Jellow was conceived by researchers at IDC School of Design, IIT Bombay, and is implemented through Jellow Labs; its journey began in 2004.

Key features

Basic and personalised boards

Jellow Basic is designed especially for children, including toddlers aged 3+ and early learners. Its roughly 1,200 icons and more than 10,000 premade sentence lines give users a substantial bank of ready-made expressions, while a keyboard supports composing new spoken sentences. The 16 listed languages include Bangla, English, French, German, Hindi, Spanish, Tamil and Urdu, making Basic the clearest fit for multilingual communication in this suite. Google Text-to-Speech provides voice output.

Basic works offline, although internet access is needed to download the app and add languages. External switch support and built-in accessibility features provide another access route for people who cannot rely on touch alone. These options make Basic more adaptable than a touch-only board, but the facts do not establish how much can be customised beyond adding languages and using the keyboard.

Jellow Customised lets users create personal boards from library icons or their own images and text. That is useful when a standard vocabulary needs tailoring; the maker says it is free to use for now.

Tools for adults and specific situations

Jellow Plus is designed especially for adults, with around 5,000 icons organised by parts of speech to build words, phrases and sentences. That structure offers a broad vocabulary for constructing messages, but Plus is currently available in English, with Indian, American, British, Australian and Nigerian accents. It is therefore a less suitable choice when a user needs another language.

Jellow Care is intended for people with sudden speech or hearing loss. Its predefined expressive sentences and one-touch yes-or-no communication are aimed at quick exchanges rather than building a broad, personalised vocabulary. Jellow Talk converts speech to text and reads typed text aloud; continuous listening, searchable conversation threads and offline use make it suited to capturing and producing text-based conversation.

Pricing

Jellow Basic costs nothing and is freely downloadable as an AAC communicator; a PDF booklet and flashcards are also available. It is the practical starting point for children and early learners who need the ready-made vocabulary, multiple languages and offline use.

Jellow Plus Basic costs nothing, billed free for lifetime, but provides only limited content from the Jellow Plus content library. It suits users who want to begin with some Plus vocabulary without paying, but the restricted library is a meaningful trade-off for anyone relying on a fuller adult vocabulary. Jellow Plus Pro provides access to all content in the Plus library, with monthly and yearly recurring plans at custom pricing.

Jellow Customised is free to use for now. The listed plans do not give a price for Plus Pro, so compare the cost with the value of full library access before choosing a recurring plan.

Platforms

Jellow supports Android, iOS, Windows and web. Basic’s offline operation can help when a connection is unavailable, though downloading the app and adding languages require internet access.

Who it's for

Jellow Basic is the strongest fit for children, toddlers aged 3+ and early learners who benefit from ready-made sentences, a keyboard and multilingual vocabulary. Customised may suit users who need their own images and text on boards. Adults who want a large parts-of-speech vocabulary can consider Plus if English works for them; people with sudden speech or hearing loss may find Care’s short expressive sentences and one-touch responses more relevant. Talk is the option for users who need speech transcribed or typed text read aloud.

Pros and cons

• Pros: Basic combines around 1,200 icons, more than 10,000 premade sentence lines and 16 listed languages, giving children and early learners a broad starting vocabulary.
• Pros: Offline use and external switch support give Basic practical access options beyond an internet-dependent, touch-only setup.
• Pros: The suite addresses distinct needs through adult-focused Plus, sudden-loss-focused Care and text-focused Talk, rather than treating every user as the same audience.
• Cons: Plus is currently English-only, limiting its fit for adults who need another language.
• Cons: Plus Basic includes only limited library content, while full Plus Pro access requires a recurring plan at custom pricing.
• Cons: Basic needs an internet connection for initial download and adding languages, despite supporting offline use afterward.

Alternatives

• AsTeRICS AAC is a free alternative with a free plan and support for Android, iOS, Linux, macOS, self-hosted use, web and Windows; choose it if those platforms matter more than Jellow’s stated age- and situation-specific tools.
• Cboard has a free forever plan with online neural voices, board and tile copying, publishing, sharing and usage analytics; consider it if those board-sharing and analytics capabilities are a priority.
• Flexspeak AAC offers a free evaluator license for one professional, capped at 10 visuals per month, with real-time translation in 30+ languages; it may suit evaluation work where translation is central.

• Spoken keeps core app features free and offers premium features through subscription or purchase; it is another option for users weighing a free core against paid additions.
• TD Snap is free to download on iOS and Windows, but speaking requires a monthly subscription after a one-month free trial; consider it if those platforms and a trial before paid speaking access fit your needs.

Verdict

Jellow is a strong starting choice for children and early learners who need a multilingual AAC board, offline use and external-switch access. Its range of tools also gives adults and people with sudden speech or hearing loss options aimed at their circumstances. Look elsewhere if an adult user needs AAC in a language other than English, or if Plus Pro’s custom-priced recurring plans do not fit.
