## Purpose

Purpose positions itself as an always-available AI mentor for personal growth. You talk to it about whatever you are dealing with — stress, decisions, conflicts or long-term goals — and it listens, reflects back what matters most, and breaks large challenges into small, actionable steps. The stated goal is a support system that learns more about you in ten minutes than a traditional coach might in weeks.

The product is built on evidence-backed psychological frameworks and covers mindset, well-being, relationships and career growth. Alongside open-ended chat, it offers personal quests that turn intentions into habits, a 24/7 support layer for everyday decisions, and personalized insights into personality and ability that surface blind spots and opportunities. It is available as an iOS app, an Android app and a web app so conversations continue seamlessly across devices.

Pricing is consumer-friendly and subscription based. New users get a free trial period, after which the plan runs either monthly or annually, with a 30-day money-back guarantee on the first charge. Purpose is explicit that it is a personal-growth mentoring tool rather than therapy or medical advice, and it emphasizes that your data is encrypted, access is restricted, your information is never sold, and you can delete your account and data at any time from Settings.

**Pricing & Plans:** Free trial (typically 7 days), then subscription: about $19.99 per month or about $99.99 per year, with a 30-day money-back guarantee on your first charge. App Store and Google Play prices can differ.

- **24/7 AI mentor chat:** Honest, challenging feedback on personal and professional challenges, available at any hour through chat.
- **Evidence-backed frameworks:** Guidance grounded in established psychological frameworks for mindset, well-being, relationships and confidence.
- **Personal quests and habit building:** Personal quests guide you toward new habits and deeper self-awareness with structured follow-through.
- **Personalized insights:** Insights on your personality and abilities reveal blind spots and highlight the biggest opportunities for growth.
- **Private and secure by design:** Data is encrypted in transit and at rest and can be deleted on demand, and Purpose is not a clinical or medical service.

**Strengths:** Available 24/7 on iOS, Android and web; Grounded in established psychological frameworks; Free trial makes evaluation low risk; Clear privacy stance with on-demand data deletion

**Limitations:** Not a substitute for licensed therapy or medical care; Discontinuing a paid year forfeits the remaining period; Heavy reliance on self-reported input shapes quality of guidance

## 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
