## Mixl (LZR Focus)

LZR Focus, distributed under the Chrome Web Store listing formerly named Mixl, is a browser-sidebar productivity tool built around a simple idea: most people drift not because they lack willpower but because they never turned an intention into a concrete task with a time box. Opening the sidebar starts a short conversation with an AI coach that helps you phrase a SMART goal, then turns that goal into a timed focus session of between five and 120 minutes.

The music angle is what distinguishes it from a plain Pomodoro timer. Focus music is generated by AI and played directly from the sidebar, with saved tracks looping in sequence and fresh tracks generated when the playlist empties. For people who find silence distracting or who fall down rabbit holes searching for the right playlist, this keeps everything in the same pane as the task.

The third pillar is an optional Focus Score. With your permission, it sends the active tab's title and domain plus your session goal to an AI service and returns a relevance estimate. The extension explicitly frames this as tab relevance rather than a measure of attention or output, and the developer's disclosure says data is not sold or used outside core functionality. Session recaps and a brief celebration close the loop, and the AI coach can be sampled as a guest before you sign in.

**Pricing & Plans:** Free to install and use with the AI coach available as a guest; continued coaching requires sign-in and the Chrome Web Store lists the extension as free with a Freemium-style model. No published paid tiers were visible on the listing.

- **AI goal coach for SMART goals:** Describe a vague intention and the coach helps turn it into a Specific, Measurable, Achievable, Relevant and Time-bound goal you can review and edit before starting.
- **Flexible 5-120 minute focus timer:** Pick a session length anywhere from 5 to 120 minutes and watch a calm countdown in the sidebar without leaving your work for another dashboard.
- **AI focus music playlists:** Optional AI-generated focus music plays from the sidebar, and new tracks are generated when the playlist runs out.
- **Optional Focus Score:** An optional Focus Score estimates how closely your open tabs relate to your goal, using only tab title and domain, with tab checks running only during active sessions.
- **Session recap and streaks:** Each session ends with a recap and a brief celebration, and you can immediately queue up another session.

**Strengths:** Turns vague intentions into an editable SMART goal before starting; Focus music generated in-app, so no playlist hunting; Focus Score is genuinely optional and disclosed in detail; Session recap plus optional celebration adds a light accountability loop

**Limitations:** Requires an internet connection and sign-in for continued AI coaching; Optional Focus Score shares active tab title/domain with an AI service; Music generation is limited to focus-session playlists rather than full music production; Only available as a Chrome sidebar extension, not standalone apps

## 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
