ReExplain
ReExplain
Upload a PDF, re-explain the ideas in your own words, and let AI challenge your understanding with adaptive questions.
Key features
- Upload PDF Materials: Drop in a textbook chapter, paper, or study notes (up to 4 MB / 25 pages)
- Feynman-Style Sessions: Re-explain the material in your own words as an interactive exercise
- Adaptive Questioning: AI generates follow-up questions that target your specific weak spots
- Understanding Gap Detection: Surface concepts you thought you knew but cannot articulate
- GPT 5.6 Powered: Uses a current frontier model for question generation and evaluation
- Dark Mode: Comfortable reading experience for long study sessions
Best for
- Study a textbook chapter before an exam and verify comprehension actively
- Digest a research paper by re-explaining sections in plain language
- Prepare for oral exams or interviews where you must talk through concepts
- Turn passive re-reading into active recall for durable memory
- Identify blind spots in your understanding of technical material
- Onboard yourself to a new subject area using materials you already have
Worktrunk
max-sixty
A Rust CLI that makes git worktrees as easy as branches, built for running several AI coding agents in parallel without collisions.
Key features
- Branch-Addressed Worktrees: wt switch, wt remove, and wt list refer to worktrees by branch name with paths computed from a configurable template, replacing multi-step git worktree incantations.
- Agent Launch in One Command: wt switch -c -x claude <branch> creates the worktree, enters it, and starts the agent in a single invocation.
- Lifecycle Hooks: Run commands automatically on create, pre-merge, and post-merge to automate setup and teardown for every new worktree.
- LLM Commit Messages: Generates commit messages from the diff so parallel agent branches stay legible without hand-writing every message.
- One-Command Merge Workflow: Squash, rebase, merge, and clean up the worktree and branch in a single step rather than a sequence of git commands.
- Interactive Picker: Browse worktrees with streaming CI status alongside diff, log, PR, and comment previews before switching.
- Shared Build Caches: wt step copy-ignored gives ten worktrees their own target/ and node_modules/ without rebuilding or copying, using reflinks on APFS, btrfs, and XFS.
- Per-Worktree Dev Servers: A hash-port template filter assigns each worktree a unique port so parallel dev servers do not conflict.
Best for
- Parallel Agent Runs: Give each of five to ten concurrently running AI coding agents its own worktree so their edits never collide.
- Fast Branch Context Switching: Jump between in-flight changes by branch name instead of navigating sibling directories by path.
- Pull Request Review: wt switch pr:123 checks out a pull request's branch directly for local inspection or testing.
- Monorepo Iteration: Share heavy build artifacts across many worktrees so each new branch is usable immediately instead of after a full rebuild.
- Automated Branch Setup: Use create hooks to install dependencies, copy env files, or start services whenever a worktree is made.
- Multi-Branch Status Review: wt list --full shows CI status and AI-generated summaries for every active branch in one view.
