## Kumo Study

Kumo Study is a Chrome extension designed around the study habits of people with ADHD. Instead of stacking separate apps for planning, timing, and distraction blocking, it puts a weekly planner, a customizable interval timer, a site blocker, and a research bookmark manager into a single browser toolbar surface. The result is one place to see what needs doing, start a focused session, and keep tempting sites out of reach.

Progress tracking and gamification are central to the design. Users earn points and rewards for completing tasks and routines, can interact with friends, and can watch goals accumulate over time. The bookmark area is built for students who write papers: quotes and citations go into custom folders with notes and drafts attached, and everything stays searchable by tag so research does not get lost.

Kumo also supports collaboration, which is unusual for a study tool. A mentor, occupational therapist, study buddy, or family member can join through a collaborator dashboard, add tasks, help shape routines, and send incentives. The free plan covers core planning with 30 bookmarks and 3 blocked sites plus a 15-day trial of Unlimited Kumo, while Kumo Unlimited removes the caps and unlocks collaborators and sensory profile insight for $9.99 per month. Schools and teams can request a custom Business package that includes student performance monitoring and training.

**Pricing & Plans:** Kumo Study is freemium. The free plan includes a 15-day Unlimited trial, a planner, 30 bookmarks, 3 blocked sites, the study timer, and progress tracking. Kumo Unlimited is listed at $9.99 per month (with annual billing available), adding unlimited bookmarks and blocked sites, collaborators, and sensory profile insight. A Business tier is quoted on request.

- **ADHD-friendly planner:** Plan the week, set daily routines, and track progress so important tasks stop slipping through the cracks.
- **Customizable study timer:** Break study sessions into manageable intervals to prevent burnout and protect concentration.
- **Site blocker:** Restrict distracting websites during study or research sessions so focus is not interrupted.
- **Research bookmarks:** Store quotes and citations in custom folders, add notes and drafts, and retrieve them by search or tag.
- **Collaborator dashboard:** Invite a mentor, therapist, or family member to add tasks, adjust routines, and send incentives.

**Strengths:** Purpose-built for ADHD study patterns instead of being a generic task app; Combines planning, timers, blocking, and citation bookmarks in one extension; Collaborator dashboard lets mentors or therapists support progress directly; Generous free plan with a 15-day unlimited trial

**Limitations:** Requires installing a Chrome extension rather than working as a standalone web app; Advanced collaboration and unlimited usage sit behind the paid tier; The ADHD-specific framing is excellent for its audience but narrows its appeal for general study users

## 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
