We compared 8 AI IELTS and TOEFL prep platforms on all four skills — Writing, Speaking, Reading, Listening — plus grading transparency, free options and price.
In short: The best AI IELTS and TOEFL prep platforms in 2026 are LingoForge (all four skills, examiner-rubric grading, persistent AI tutor), ELSA Speak (pronunciation), TestGlider (timed mocks), Cathoven (full platform), and the British Council's IELTS Ready (free official practice). Every platform below covers Writing; far fewer cover Speaking, Reading and Listening — and even fewer publish how accurate their scores are.
Disclosure: we make LingoForge, one of the platforms below. Everything we say about the others comes from their own websites, read in November 2026. Where a site does not state something, we say so — we do not guess.
We scored each platform on five things: which of the four exam skills get AI feedback, whether grading follows the official rubric criteria, what you can check for free, whether the vendor publishes how accurate its scores are, and price. No vendor paid to appear here.
Platform | AI skills covered | Per-criterion scores | Free check | Publishes accuracy method | Price (Nov 2026) |

British Council IELTS Ready | Short mocks | Estimated | Free | Official body | Free / w/ booking |
LingoForge is one of the few prep platforms that grades all four IELTS skills — Writing Task 1 and 2, Speaking Parts 1–3, Reading and Listening — against the official rubric criteria, not a single overall number. Its ForgeTutor keeps a persistent profile of each learner's weak points and schedules review before they're forgotten. One free writing grade per day, no account required.
ELSA built its name on pronunciation feedback, and it shows: its word-level pronunciation scoring is the deepest in this list. But pronunciation is one of the four official Speaking criteria — fluency, lexical resource and grammar are lighter. IELTS and TOEFL Writing, Reading and Listening are not its focus.
TestGlider offers timed IELTS and TOEFL mock tests with what it calls "2-minute AI grading", and its IELTS mocks are hosted on IDP Hong Kong's site — a meaningful endorsement. Coverage centers on mock-test simulation rather than skill-by-skill tutoring.
Cathoven covers all skills and claims its Writing and Speaking scores land within 0.5 band of examiner scores in 98% of cases — the boldest accuracy claim in the category, though the methodology behind it is not published. Premium starts around $21 a week.
E2 mixes self-paced AI practice with live classes and tutor feedback across IELTS, PTE, TOEFL and OET. If you want a human in the loop, it's the strongest option here — you pay for it in course prices rather than app prices.
Magoosh covers IELTS and TOEFL with deep video lessons and a large question bank. Its AI features are thinner than the AI-native platforms — best for learners who prefer structured courses over instant AI feedback.
BestMyTest pairs a large question bank with video lessons for both exams. AI feedback is limited compared to AI-native platforms; better for volume practice than for rubric-level feedback.
Short mock tests with AI feedback are free, and booking your test through the British Council bundles 40 full mocks. IELTS only — no TOEFL — and feedback is lighter than dedicated AI platforms, but it's the safest free starting point.
Want all four skills graded to the rubric: LingoForge, Cathoven
Speaking/pronunciation is your weak point: ELSA Speak (+ a writing checker)
Live human feedback: E2 Language
Free official practice: British Council IELTS Ready
Timed mock-test realism: TestGlider
Are AI band scores accurate? Treat any AI band as a range of roughly half a band either way. The useful part is the per-criterion feedback, not the number itself — check whether a platform publishes how its scores were validated.
Can AI replace an examiner? No. Real IELTS Writing and Speaking are marked by certified examiners. AI practice scores are predictions — good ones track the official descriptors closely enough to show you what to fix.
Which platform covers all four skills? LingoForge, Cathoven and cover Writing, Speaking, Reading and Listening. ELSA is speaking-focused; TestGlider is mock-test-focused; British Council covers IELTS only.
Updated November 2026. Prices and features from each vendor's website; where a vendor does not publish something, we say "not stated" rather than guess.
