## LoadMuscle

The app works in three steps. First you describe yourself: goal, experience level, training days, and whether you train in a gym, at home with dumbbells, or with bodyweight only. Second, you get a complete week laid out day by day, with exercises, sets, reps, timing and an animated demo for every movement so you know exactly how to perform it. Third, you train and track: follow the session, log your progress, and let the plan evolve as you get stronger.

Beyond the AI generator, LoadMuscle ships hundreds of pre-built programs across goals and styles — weight loss, home workouts, strength, HIIT and cardio, calisthenics, quick sessions, core and abs, glutes and legs, warm-ups, and yoga and mobility. Ready-made plans include popular structures such as full-body three-times-a-week, upper/lower splits and three-day push-pull-legs schedules. The exercise database is unusually deep, with more than 4,000 movements each accompanied by instructions and a demonstration.

LoadMuscle is a mobile-first product available on iOS and Android, connected to a web presence with a workout planner, exercise search and a fitness blog. It is freemium: there is a free version that users describe as genuinely usable, with a subscription unlocking the full AI coach and complete plan access. It scores around 4.5–4.6 stars across the App Store and Google Play.

**Pricing & Plans:** LoadMuscle is freemium. The app can be downloaded free and its free tier covers the core workout planner, ready-made plans and the exercise library; an in-app subscription unlocks the full AI coach and expanded plan access, and it can be cancelled at any time.

- **AI workout planner:** Tell it your goal, level, equipment and available days, and the AI trainer builds a full week of training including exercises, sets, reps and minutes.
- **4,000+ exercise library:** A very deep database of movements, each with instructions and a demo animation, covering barbell, dumbbell, cable, machine, calisthenics and mobility work.
- **Pre-built workout plans:** Hundreds of ready programs across weight loss, home, strength, HIIT, calisthenics, core, glutes and legs, plus structured splits like full-body, upper/lower and push-pull-legs.
- **Progress tracking:** Follow each session, track what you complete, and let the plan adapt as your strength and consistency improve.
- **Gym and home modes:** Works equally well for a full gym setup, a home setup with limited dumbbells, or bodyweight-only training with no equipment at all.

**Strengths:** Plans are generated around your actual equipment and schedule, not a one-size-fits-all template; Exceptionally large exercise library with a demo for each movement; Free tier is genuinely usable, with the AI coach as the paid upgrade; Strong store ratings across both iOS and Android

**Limitations:** Mobile-first: the full AI coach experience lives in the app rather than the web; The most valuable AI planning and expanded plan access require a subscription; Abundant exercise choice can feel overwhelming for absolute beginners without clear direction

## 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
