## 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

## Sekai

Sekai is built around a simple idea: interactive content should be immediate. Instead of downloading a game or installing a creative suite, you open a link, play or build, and share the result. The homepage surfaces top creators of the week alongside curated categories — meme, relax, art, strategy, action, puzzle, simulation, casual, sports, racing, card and board — so there is always something to open within a click.

The creation side is what distinguishes Sekai from a plain game portal. Users can start from scratch or remix an existing creation, which has produced a catalogue heavily shaped by collaborative iteration: meme stretchers, ragdoll sandboxes, sticker canvases, piano and synth toys, quizzes and simulator games all appear in dozens of community-made variants. That remix loop keeps the library growing without relying on a central studio.

Sekai is distributed as a web platform and as iOS and Android apps, so the same link works on a phone or desktop. Creations are lightweight, load fast on modest hardware and are designed for quick sharing — which suits classrooms, group chats and creative experimentation as much as gaming.

**Pricing & Plans:** Browsing, playing, creating and remixing are free. An account is optional and is used mainly for managing drafts and published creations.

- **Endless discovery feed:** A constantly updated feed of trending creations, top creators and curated categories such as meme, relax, strategy, action and puzzle.
- **Create and publish your own app:** A studio that lets you build a playable mini-app, then publish it to the community in minutes.
- **One-tap remixing:** Take any published creation, change it and re-release your version — the engine behind most of the catalogue.
- **Instant play, no download:** Everything runs in the browser with no install, and the same creations work on iPhone and Android through the Sekai app.
- **Creator community and profiles:** Profiles, plays and creator rankings turn the catalogue into a social space rather than a static gallery.

**Strengths:** Zero friction: no downloads, installs or launchers to play or create; Remix culture gives the catalogue constant variety; Fast, lightweight creations that run on desktops and phones alike; Broad creative range from games to polls, stickers, piano toys and spin-the-wheel tools

**Limitations:** Curation and discovery can feel chaotic because anyone can publish; Many creations are remixes of the same trending ideas; Quality varies widely between top creators and casual experiments; CloudFront-edge blocking occasionally trips automated crawlers
