Product details come from vendor pages and may change.Disclosure: Siftino earns affiliate commissions from some links in this article, so the links are not neutral. These three tools are selected options, not a ranking of the whole market. Of the three, only Speak is described by its vendor as a language-learning product.
Use cases
- Speaking practice with an AI tutor: Speak describes a loop of learning phrases, practicing them, then applying them in a back-and-forth conversation with the Speak Tutor.
- Guided help with schoolwork or writing: Khanmigo is described as a tutor that guides learners toward answers instead of handing them over, and the page mentions an AI-enhanced writing practice tool.
- Math homework explained in English: Photomath offers step-by-step explanations for scanned problems, including word problems. It is a math tool, not an English course.
Speak
According to the vendor page, Speak is a language learning app with an expert-crafted curriculum personalized by AI. English is among the listed languages, alongside Korean, Japanese, French, Spanish, Italian, and Chinese. Lessons focus on phrases native speakers use in real situations rather than textbook sentences or grammar drills. In the conversation step, the vendor says you get feedback on what matters and can repeat as often as you like.
Limitations: the page offers a free start and mentions a trial, but the excerpt gives no prices or billing terms, so check them before subscribing. The reviews on the page are the vendor's own selection and should be read as marketing.
Khanmigo
According to the vendor page, Khanmigo is an AI tutor and teaching assistant from Khan Academy, with offerings for learners, parents, teachers, and districts, plus a writing tool. The vendor says it guides learners instead of giving direct answers and is tied to Khan Academy's content library, which covers math, humanities, coding, and social studies.
Limitations: the page does not describe a dedicated English-as-a-second-language curriculum. Parents who subscribe monthly or annually can enable access for up to 10 children under 18. Teachers cannot grant students access, because classroom access is only available through school or district implementations. The excerpt gives no subscription prices, so they are unknown here.
Photomath
According to the vendor page, Photomath lets you scan a problem, including word problems, or type it into a smart calculator. It shows step-by-step explanations, and some problems offer multiple methods. Topics run from elementary math through calculus.
Limitations: the page describes no language-learning features. The listed plans are:
- Basic: $0 USD
- Billed annually: $69.99 USD
- Billed monthly: $9.99 USD
The source does not say what the trial includes or how long it lasts.
