## Hearify

Hearify positions itself as an AI question generator rather than a simple quiz builder. You feed it source material — a block of text, a PDF, or a video — and it returns a structured set of questions you can then refine. The editing step matters: generated items are treated as a first draft that teachers and trainers adjust, which is exactly how reviewers in education and IT describe using it.

Beyond classroom use, the platform is deliberately horizontal. HR teams run culture-fit and onboarding checks, event organisers build gamified trivia, marketers create interactive funnel quizzes, and community managers collect information through playful forms. Adaptive difficulty, multimedia questions and white-label branding make those varied scenarios possible without a bespoke build.

Reporting is a core part of the product: Hearify analyses responses and surfaces where knowledge is solid and where it is thin, and results can be exported for records or reporting. Integration with learning management and collaboration systems is promised so the tool slots into existing workflows rather than sitting beside them. Users in more than a hundred countries are cited, which speaks to the breadth of the audience it is designed to serve.

**Pricing & Plans:** Freemium: generate quizzes for free, with paid tiers for higher volumes, branding and advanced features. See the pricing page for current limits.

- **One-click quiz generation:** Turn pasted text, PDF files or video transcripts into a full quiz in a single pass, then edit or discard any question.
- **Adaptive difficulty:** The tool adjusts question type and difficulty to the learner's level, so assessments fit different audiences.
- **Multilingual support:** Ask questions in the languages your learners, staff or customers actually use.
- **Multimedia questions:** Add images, video and charts to questions instead of relying on plain text.
- **White-label branding:** Apply your logo, palette and styles so assessments look like part of your own platform.
- **Results analytics:** See knowledge gaps, strengths and completion data, then export results for reporting.

**Strengths:** Turns text, PDFs and video into questions without manual authoring; Editing tools keep a human in control of the final question set; Adaptive difficulty and multimedia support fit many learner levels; White-label branding and LMS integrations suit organisations

**Limitations:** Generated questions usually need a human editing pass; Advanced features and larger volumes sit behind paid tiers; No offline mode; requires a browser and internet connection

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
