## Flashka

Flashka starts from your source material rather than the open internet. You upload a PDF, a slide deck, a Word document, a photo of a textbook page, or a lecture recording, and it produces study assets from exactly what you will be tested on: flashcards, full quizzes and mock exams, oral exam practice with spoken feedback, case studies, mind maps, notes, and a transcript of the recording. Image occlusion turns diagrams and anatomy figures into interactive cards, and you can import an existing Anki deck into the app.

The learning loop is built on active recall and spaced repetition. Every card shows the question first, you answer from memory and rate how well you knew it, and the algorithm decides when that card returns, with short intervals for hard cards and longer ones for easy ones. Cards that you keep forgetting are flagged as critical so you can rewrite them, and once you set an exam date, the exam planner tells you how much to review each day. Reviews, editing, and notes are unlimited on every plan, including Free.

Professor Ka acts as a 24/7 tutor and can also modify your material on request, for example turning one concept into cards or a chapter into a quiz. The app tracks streaks, study time, and mastery points, and includes study groups and leaderboards for studying alongside classmates. Flashka is available on the web, App Store, and Google Play, supports material in any language, and comes in two paid tiers plus a daily free allowance.

**Pricing & Plans:** Free plan with daily limits (for example, 1 card generation, 1 quiz, 1 oral exam, 1 case study, 1 transcript, and 10 tutor messages per day) and generous unlimited editing and reviews. Paid tiers, Beast and Wizard, raise or remove those limits; Wizard is unlimited. Exact prices are shown in the app.

- **Material-based flashcards:** Upload PDFs, PowerPoint or Keynote slides, Word and Pages documents, images, or lecture audio and get flashcards built from exactly your source content.
- **Spaced repetition scheduling:** Review intervals grow as you remember a card and shrink when you forget, with hard cards flagged as critical so you can fix them.
- **Quizzes and mock exams:** Generate full quizzes and timed mock exams from your material, alongside oral exam practice that scores what you actually said out loud.
- **Professor Ka AI tutor:** Ask questions about anything you get stuck on, or ask Ka to rework your material into new cards, quizzes, or notes.
- **Mind maps, notes, and exam planner:** Turn dense chapters into visual maps, condense lectures into notes, and set an exam date to get an adaptive daily study plan.

**Strengths:** Everything is generated from your own material rather than generic internet content; Reviews, editing, and notes are unlimited even on the free plan; Covers the whole study cycle: cards, quizzes, oral exams, case studies, mind maps, and planning; Available on web, iOS, and Android, with support for material in any language

**Limitations:** Free and mid-tier plans cap generations of cards, quizzes, transcripts, and tutor messages; Importing existing Anki review history was still listed as coming soon at the time of review; It is a consumer study app, so teams and institutions get no admin or classroom tooling

## Periplus

Periplus starts from a prompt: type a topic, ask a question or drop in a PDF, and it generates a full course with chapters that build on one another. Lessons link to related documents, so you can open two side by side or follow a graph of connected ideas. Every lesson can branch into a new course, letting you drill into a detail without losing your place. Anything you open is stored in a personal library that is searchable and resumable, and new courses can pick up where your existing knowledge ends.

Learning support is built into the flow rather than bolted on. Each lesson can convert into flashcards and quizzes, which resurface on a spaced schedule timed to appear just before you would forget. Courses can also be turned into podcast episodes: two AI hosts walk through the chapters, captions follow the audio word by word, and you can raise your hand to ask a question mid-episode. Lessons can include maps, diagrams and worked math. On the Premium tier, deep research pulls in web sources you can open yourself, and PDF-based courses build the curriculum around your own material.

Periplus is explicit about its difference from ChatGPT: instead of you deciding what to study next, the platform lays out the curriculum, tests you as you go, and guards against hallucinated content by checking lessons before they are shown. It supports multiple languages, chosen at signup or changed in settings, and generates everything in the selection. There is a free plan with no credit card required for creating courses and taking quizzes.

**Pricing & Plans:** Freemium. The free plan covers course creation and quizzes without a credit card; Premium removes usage limits and adds features such as PDF-based course generation and deep research with web sources.

- **AI course generation:** Type a topic or question and get a chapter-by-chapter course, with any lesson able to branch into a new, linked course.
- **Spaced-repetition flashcards and quizzes:** Any lesson converts into flashcards and quizzes that return on a schedule timed for just before you would forget.
- **Course-to-podcast audio:** Each chapter becomes a podcast episode hosted by two AI voices, with word-level captions, transcripts and the ability to ask questions out loud.
- **Linked knowledge graph:** Documents link to related lessons so you can compare side by side or follow connections across subjects.
- **PDF-based learning:** On Premium, upload a lecture or paper and Periplus builds a course around it, or lets you chat with the document directly.

**Strengths:** Structured courses rather than unstructured chat answers; Flashcards and quizzes scheduled with spaced repetition; Podcast format with captions lets you learn hands-free; Free plan available and no credit card required to start

**Limitations:** PDF upload and deep research are limited to Premium; Course quality depends on the AI's source coverage for niche topics; Everything is AI-generated, so critical reading is still advised
