Kinnu

Kinnu is a learning technology company that makes two kinds of product: exam prep platforms for specific high-stakes tests, and a general knowledge app for people who simply want to learn more. Its home page states the goal as "Time To Mastery = 0", the idea that learning anything should take as little time as possible, and says the company gets there with "an arsenal of cognitive science, memory, and motivational tools". Both products are for learners. The exam prep side serves candidates for the Solicitors Qualifying Examination (SQE), the SAT, the CFA Level I exam and the Board Certified Behavior Analyst (BCBA) exam. The general knowledge side serves curious adults who want to build up their knowledge a little each day. The company, KINNU Ltd, gives a London address.

Kinnu Exam Prep

The home page describes Kinnu Exam Prep as "The all-in-one exam prep platform with the highest quality MCQ practice questions, flashcards, study notes, detailed performance stats and AI-powered learning assistant". Those five pieces are what a candidate works with on every exam the platform covers:

• MCQ practice questions, which Kinnu calls the highest quality available, for question-by-question practice.
• Flashcards for reviewing key points between question sessions.
• Study notes that explain the syllabus, which Kinnu says it rewrote as "Smart Study Notes" for law and overhauled again when it added the SAT.
• Performance stats that show where a learner is strong and where they are losing marks.
• An AI learning assistant that answers questions about the material as the learner studies.

The platform is organized by exam, and each has its own entry in the product list.

SQE (Kinnu Law). The Solicitors Qualifying Examination is the exam Kinnu has built out furthest. Kinnu Law launched as a mobile app in May 2025, described as "A dedicated mobile app to help candidates pass the SQE on their first try", with 3,000 practice MCQs and a "bespoke SQE-specific AI model to answer any question". The company reports that within 8 weeks, 20% of exam takers had begun using it for over 1 hour per day. In October 2025 it came to the web with Smart Study Notes, "better questions" and "even smarter AI", and the company now calls Kinnu Law "the all-in-one platform to pass the SQE".

CFA. Kinnu CFA Prep launched in February 2026 as "A dedicated platform to help candidates pass the CFA level I on their first try". It brings the same mix of question practice, notes and AI help to the first level of the Chartered Financial Analyst program.

SAT. In July 2026 Kinnu added the SAT, and used the launch to overhaul its study notes "to help students achieve their dream score". This puts a high school admissions test on the same platform as two professional qualifications.

BCBA. The product list also includes Kinnu BCBA for the Board Certified Behavior Analyst exam, alongside the other three.

Kinnu General Knowledge

The general knowledge app is the product Kinnu started with, and it works differently. Instead of a syllabus, learners pick from what the home page calls "a universe of free and fascinating pathways" and "watch your knowledge grow over time". The pitch is "Goodbye edutainment, hello superpower learning", and the page adds, tongue in cheek, "Warning – might cause severe learning addiction." The first version, launched in March 2022 as "Kinnu: Superpower Learning", is described as "A free app" for people who want to learn anything they want, and passed 500k installs. Kinnu 2.0 followed in February 2024, rebuilt with what the company learned from its research lab, and the timeline reports over 1.2m installs and thousands of 5-star reviews.

Research behind the product

Kinnu presents its learning design as tested rather than assumed. In September 2024 it launched Kinnu Labs, "A virtual learning lab with over 10k participants to test learning features, benchmarked against the gold standard: human tutors". The company reports that in those tests Kinnu "outperformed 1:1 IRL human tutors in high-school level physics and history". The finding comes from Kinnu's own lab, and it is the basis for the exam prep features that followed.

The team is described as "developers, designers, scientists and writers", with 46 years of combined experience in education and cognitive science. The home page also lists a set of company values, from "Zero Imposters" to "Nothing is sacred", and says Kinnu is hiring AI specialists, engineers, operations leads, marketing pros and learning scientists.

Scale, funding and reviews

The home page counts 1.2 million users, 3.2 million hours learned and 90 million question sessions across Kinnu's products. The timeline gives the funding history: the company was founded in July 2021, raised a $2.5m pre-seed round in January 2022 from European angel investors, and raised a $6.5m seed round in March 2023 from LocalGlobe and Spark, which the page describes as the investors behind Anthropic, Slack, Coinbase and Monzo. In total, the team section says, Kinnu has raised $9m.

Learner quotes on the page are short and enthusiastic. Gregory S. writes "If Da Vinci made an app he would've made Kinnu.", Sonya S. writes "I never review apps, but this one is so good I had to.", and Floris T. says "You get so much smarter with way less work." The company keeps a community on Discord and accounts on LinkedIn, Instagram and X, and links a blog and a contact page.

Prices and access

The home page sends learners to each exam platform's own page and does not list subscription prices for the exam prep products. The general knowledge app is the one product it describes as free, in both its launch entry and its "free and fascinating pathways".

Who it suits

Kinnu's exam prep suits candidates who study on their phone and want a lot of question practice with an AI helper on hand: a trainee solicitor drilling SQE multiple-choice questions, a finance graduate preparing for CFA Level I, a behavior analyst preparing for the BCBA, or a high school student revising for the SAT. The SQE platform is the most developed, with its mobile and web versions and its 3,000-question bank, so law candidates have the most to gain.

The general knowledge app suits adults who want a daily learning habit rather than a certificate. The main limitation is the narrow exam list: anyone preparing for a test other than these four will not find it here yet, and candidates who want a live tutor or a classroom course should know the platform is built for self-study with AI support.
