Grammarly

Trending

Simplified into one Pro tier in 2026 — but AI prompt caps are where it bites

Grammarly remains the most widely adopted AI writing assistant, checking grammar, spelling, tone and clarity across virtually every app and browser via its extension, desktop app and integrations. Its 2026 pricing genuinely got simpler on paper: the old separate Premium and Business plans folded into a single Pro tier, so any older article describing those legacy plans no longer reflects current offerings — there are now just three tiers: Free, Pro, and Enterprise. Pro runs $12/month on annual billing (or $30/month paid monthly) and bundles grammar checking, AI rewriting, plagiarism detection, AI text detection, fluency suggestions, style guides, brand tones, snippets and team analytics — genuinely comprehensive for the price. The catch worth understanding before upgrading: the meaningful gap between Free and Pro isn't really about grammar-checking depth, it's AI prompts specifically — Free includes 100 AI prompts/month while Pro jumps to 2,000, and daily AI-heavy users report this cap is where the free plan actually becomes limiting, not the core proofreading itself. Review sentiment is notably split by platform: strong 4.7/5 scores on both G2 (12,969 reviews) and Capterra (7,210 reviews), but a more mixed 3.5/5 on Trustpilot from 10,394 consumer reviews — reflecting real frustration some users report around billing surprises and strict refund terms, worth reading before committing to annual billing. For daily writers, users consistently describe Pro as paying for itself in time saved on editing and tone adjustment compared to hiring an editor or stacking multiple narrower tools; occasional users may find the free tier's 100 monthly AI prompts genuinely sufficient without ever needing to upgrade.

Wordtune

AI21 Labs' sentence-level rewriter — improves what you wrote, doesn't correct it

Wordtune takes a fundamentally different approach from Grammarly's error-correction model: rather than flagging what's grammatically wrong, it rewrites what's already correct but could be clearer, more concise, or better toned — built by AI21 Labs, the research lab behind the Jurassic-series language models. Its suggestions stay closely anchored to your original meaning and structure, making it a genuine complement to (rather than replacement for) a grammar checker, which is why many writers use both tools together rather than choosing one. The free plan gives 10 rewrites per day, workable for light editing sessions but limiting for anyone doing sustained daily writing. The paid Unlimited plan removes that cap entirely, priced at $9.99/month paid monthly or $6.99/month billed annually — positioning it as the cheaper, more focused pick specifically for quick rephrasing and sentence-level improvement versus Grammarly's broader (and pricier) all-in-one bundle. Its core strength is short-form and sentence-level work: tightening a wordy paragraph, finding a better tone for an email, or rephrasing an awkward sentence — it's not built for long-form fiction (that's Sudowrite's territory) or comprehensive style-guide enforcement across a team (that's more Grammarly Business territory). For writers whose main friction point is "I know this sentence isn't quite right but I can't fix it myself," Wordtune's rewriting-first approach solves that specific problem more directly than a correction-focused tool, at a genuinely accessible price.

Brainly

AI-powered homework help backed by a community of millions of students checking each other's answers

Brainly combines two things most AI homework tools don't: an AI answer engine and a long-running community of over 350 million students and educators who post, verify and discuss solutions across virtually every subject and grade level. Snap a photo of a problem or type a question, and Brainly's AI generates a step-by-step explanation, while community-verified answers from real students and moderators provide a second layer of accuracy checking. That community layer is the real differentiator versus a purely AI-driven tool like [Photomath](/tools/photomath) in our [AI for Students category](/category/ai-for-students): for subjects like literature, history or open-ended essay questions where there isn't one clean numeric answer, seeing how other students approached the same assignment — plus expert-verified explanations — often clarifies more than an AI response alone. Coverage spans math, science, history, literature and language learning, broader than math-focused tools. A free tier with limited daily questions covers casual use; Brainly Plus, priced around $9.99-24/month depending on billing term, unlocks unlimited AI answers, step-by-step explanations across all subjects, and ad-free browsing — positioned as a broader homework companion rather than a single-subject specialist.

Quizlet (Q-Chat)

The flashcard app 60+ million students already use, now with an AI tutor built on top of their own notes

Quizlet built its reputation long before the AI boom as the default flashcard and study-set app for students, with a massive existing library of user-created and textbook-aligned study sets. Its AI layer, Q-Chat, uses the adaptive-tutoring method Socratic questioning rather than just handing over answers — it asks guiding questions based on your specific study set, adjusting difficulty as you respond correctly or struggle. That grounding in your own study materials is the real differentiator versus a general AI tutor: Q-Chat works from flashcards and notes you or your class already created, rather than generic subject knowledge, which keeps practice sessions aligned with exactly what you're being tested on. Quizlet Learn, the platform's adaptive practice mode, also uses spaced repetition to resurface material you're likely to forget, a well-established memory technique most flashcard apps skip. Compared to [Khanmigo](/tools/khanmigo) in our [AI for Students category](/category/ai-for-students), Quizlet leans specifically into memorization and test-prep practice rather than broad concept tutoring across a full curriculum. The core app and flashcard creation remain free; Quizlet Plus, at roughly $7.99/month, unlocks Q-Chat's full capacity, ad-free studying, and offline access.

Photomath

Point your camera at a math problem and get step-by-step AI explanations, not just the answer

Photomath is the app most students actually have installed for math homework — over 300 million downloads, acquired by Google in 2022 for roughly $100 million, and integrated with Gemini AI since 2024-2025 for its step-by-step explanations. Point your phone camera at a printed or handwritten math problem, and it recognizes it, solves it, and — critically — shows multiple solution methods with the reasoning behind each step, not just a final number. That step-by-step emphasis is the real differentiator versus a general chatbot: a student can ask "why" at each stage, see alternate methods for the same problem, and use the built-in smart calculator for manual entry when a photo isn't practical. It covers arithmetic through calculus, which is broader than tools like [Numerade](/tools/numerade) in our [AI for Students category](/category/ai-for-students) that focus more on higher-level STEM video explanations. The free tier covers core problem scanning and basic step-by-step solutions; Photomath Plus, at $9.99/month or $59.99/year (per public pricing listings), unlocks deeper explanations, extra solution methods and offline access. Parents and tutors commonly use it alongside students specifically for the explanation depth, not as a shortcut to skip understanding.

Socratic by Google

Discontinued as a standalone app — merged into Google Lens

If you're looking for the Socratic app in 2026, it's worth knowing upfront that it no longer exists as a standalone product. Founded in 2013 by Christopher Pedregal and Shreyans Bhansali, acquired by Google in March 2018, and publicly relaunched as "Socratic by Google" in August 2019, the app let students photograph a homework question and receive AI-curated resources — step-by-step solutions, relevant YouTube videos, and study guides — completely free with no ads. For several years it was a genuinely popular homework-help tool, particularly loved for its owl mascot. Around October 2024, Google began integrating Socratic's core functionality into Google Lens rather than maintaining it as a separate app, and the standalone Socratic app has since been removed from both the App Store and Google Play. Google never issued a formal, detailed public statement explaining the transition, and the Socratic website remains technically live, but the actual homework-help experience students used to get from the dedicated app now lives inside Google Lens's broader visual search and homework features instead. If you're specifically searching for "Socratic by Google" hoping to download it, the practical answer is: use Google Lens instead, which has absorbed a similar photograph-a-question, get-resources workflow. For students wanting a more purpose-built, dedicated homework-help experience rather than a feature folded into a general visual search tool, alternatives that emerged after Socratic's retirement — including various AI tutoring and math-solver apps — are generally positioned as the more direct replacements as of 2026.

Khanmigo

Trending

Khan Academy's Socratic AI tutor — $4/month on top of a free platform

Khanmigo is Khan Academy's AI tutoring layer, built specifically around Socratic-method teaching rather than simply handing over answers: it asks guiding questions, offers hints, and nudges students to think through a problem themselves before revealing a solution — a deliberate pedagogical choice distinguishing it from generic AI chatbots that just complete homework on request. It includes a code sandbox with real-time debugging feedback and a Writing Coach that can role-play as an audience or editor to help improve an essay. Critically, Khan Academy's entire core K-12 platform — videos, exercises, personalized learning dashboards — remains completely free with no ads or paywall, exactly as it has been historically. Khanmigo is the one paid layer on top: $4/month or $44/year for an individual learner or parent account, while verified US teachers get full access free. That's a genuinely low price point, though it comes with real limitations reviewers consistently flag: content and tutoring depth taper off around early college level, with no dedicated art, music or advanced coursework support, and consumer Khanmigo subscriptions currently require a US billing address. For schools, pricing is more complex and not publicly consolidated — an Enterprise Starter tier begins around $10/student/year, with a 400-student school paying roughly $4,000 annually for district-wide AI tutoring access, while districts over 1,000 students move into custom Enterprise pricing requiring direct contact. Early reviewer feedback in 2023 was mixed (one teacher found it fell short on a geometry problem and had limited historical role-play characters), though the platform has continued developing since. For individual K-12 families wanting affordable, pedagogically-grounded AI tutoring layered onto genuinely free core content, it remains one of the lowest-cost, most defensible options in the category.

Numerade

Video-based AI STEM tutoring, walking through your exact textbook problem step by step

Numerade takes a distinct approach to STEM homework help: instead of a text chatbot or a quick camera-scan answer, it pairs AI with an extensive library of educator-recorded video explanations, matched to your specific textbook problem where possible, then fills gaps with AI-generated video walkthroughs for problems without a matching human-made video yet. That matters most for subjects where seeing the reasoning matters — physics, chemistry, and calculus problem sets where a written answer alone doesn't convey diagram-drawing or the flow of an experiment. It's a meaningful complement to [Photomath](/tools/photomath) in our [AI for Students category](/category/ai-for-students): Photomath is faster for a quick arithmetic-to-calculus scan-and-solve, while Numerade leans into full video-lecture-style explanations for harder, exam-relevant STEM problems, often tied directly to specific textbook editions students already own. A subscription unlocks the full video library and AI-generated solutions beyond a limited free-question allowance, positioning it closer to a supplemental tutoring service than a quick homework shortcut — genuinely useful for exam prep rather than just checking a single answer.
