## 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

## Pi Coding Agent

Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn.

Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing.

Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site.

**Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself.

- **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
- **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
- **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
- **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
- **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL.

**Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options

**Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI
