Live on Product Hunt today
Today we're launching Understand Anything on Product Hunt. If you've ever opened a 50k-line repo and had no idea where to start, that's exactly the moment we're trying to fix.
Come say hi on the launch page — we're hanging out in the comments answering questions, sharing demos, and collecting the next round of feature requests.

Highlights
Localized analysis output — --language (#142, #145) — by @zhushen12580
/understand (and friends) now accept a --language flag. Architecture summaries, node descriptions, tours, and onboarding content are generated in the language you ask for, end-to-end through the agent pipeline. Documented across every README.
Dashboard i18n (#142 stack + 9d1318a)
The dashboard UI ships translation files alongside the analysis pipeline:
- All UI strings (sidebar, code viewer, search, tours, mobile layout) routed through
I18nProvider.
- New: Russian (
ru) joins the existing locales. MobileLayout is now wrapped in the provider so mobile screens localize too.
- Output language read from the same
outputLanguage config key for consistency between generated content and chrome.
Unified install script (#123)
Replaced the per-platform installer pile with a single install.sh / install.ps1 that detects the target CLI (Claude Code, Codex, Cursor, Copilot CLI, opencode, Gemini CLI, KIMI, Cline, Hermes, Mistral vibe) and wires up the right symlinks and config. Uninstall is robust against partial state; reparse deletes are guarded.
New platform support
- KIMI CLI (#134) — install + skill plumbing.
- Cline (#116) — install + skill plumbing.
- Hermes (#91) — open-source agent compatibility, README refresh.
- Mistral vibe (#127, by @3ng7n33r) — install script entry.
Test-coverage visualization — tested_by edges + dashboard badge (#122 / issue #113)
A deterministic tested_by linker runs during merge, with a swap-then-supplement strategy that recovers edges the per-file batches drop and a max-weight Pass-1 dedup. Tested files now render a small badge on their node card so you can spot uncovered code at a glance.
Dashboard file/class dual-view toggle (#132) — by @Xingkai98
Toggle between file-level and class-level structural views to cut clutter on large object-oriented codebases. View-state resets are scoped so the toggle stays sane when switching layers, and the detail toolbar hides in domain view where it doesn't apply.
Theme settings expose a heading-font override so teams can match their internal design system without forking.
Mobile layout + responsive dashboard (880e223)
The dashboard now has a real mobile layout instead of a horizontally-scrolling desktop. Sidebar collapses, the code viewer adapts to portrait, and tour navigation works on touch.
Closed 12 sources of silent data loss in graph extraction (c49c46d)
A pipeline-wide audit identified twelve places where nodes or edges were being quietly dropped during batched file analysis and merging. All twelve are now closed and covered:
imports edges recovered when file-analyzer batches drop them (05fd423).tested_by malformed tags coerced before adding (fdfa331, issue #113).- File-analyzer preserves language and falls back when imports unresolved (
7834f9b).
- Canonical edge direction persisted during merge so dedup doesn't lose half the edges (
f71bad5, in 2.7.1).
- Fingerprints merge made unambiguous in Phase 3d so re-runs converge (
dd8b724, in 2.7.2).
.understandignore exclusions actually applied in Phase 0 of auto-update (5304ff0).build-fingerprints.mjs bundled and Phase 7 reordered so incremental updates work on fresh installs (e7af9ae, in 2.7.3).
Auto-update / incremental pipeline (2.7.x line)
Structural fingerprinting (--auto-update / --no-auto-update) became real in the 2.7 line: only changed files re-run through analysis, fingerprints merge deterministically, and Phase 0 honors .understandignore. Big speedup on repeat runs against large repos.
Dashboard ACCESS_TOKEN override (1779cbd)
The dev server's access token can be overridden via env var for embedded/CI use cases without editing config.
Other contributions since v2.5.0
Huge thanks to everyone who improved the project this cycle:
- #147 — @rustanacexd: resolve
/understand-domain plugin root at runtime so symlink installs find their agent prompts.
- #139 — @nieao: Windows path handling and zod schema null compatibility in
/understand-knowledge.
- #127 — @3ng7n33r: add Mistral vibe CLI to the install script.
- #124 — @tipich: make
/understand work on Windows with pnpm 10.
- #121 — @Buzzwoo-Ecom-Team: customizable heading font.
- #117 — @DenisBalan: fix dashboard URL format in
vite.config.ts.
- #132 — @Xingkai98: file/class dual-view toggle.
- #142, #145 — @zhushen12580:
--language parameter and the documentation pass for it.
- #114 — fix tour navigation glitches across layers (incl.
TourFitView flicker, pending-focus-container reset, refit timeout no longer freezing).
- #112 / issue #102 — quadratic per-layer aggregations fixed (
O(N+K)); kills the slowdown on large graphs.
- #138 — git worktree path handling: skills now redirect
PROJECT_ROOT out of worktrees so they write to the main repo.
Other improvements
- Discord + enterprise contact added to the homepage; author homepage link surfaced (9ab6724, 5cef66c).
- Favicon matches homepage branding (6e0d1c1).
- Translated READMEs consolidated under
READMEs/ (b9ca060).
code-review-feedback pass for the --language PR (#145 stack).
Compat
- No graph schema changes since v2.5.0. Existing
.understand-anything/knowledge-graph.json files load unchanged.
- Install path: the new unified
install.sh / install.ps1 supersedes the per-platform installers. The old scripts still work but are no longer the documented path.
outputLanguage config key is now the single source of truth for both generated content and dashboard UI language.

Highlights
Slide-up code panel with syntax highlighting; double-click a file node to open. Path-allowlisted via the dev server's /file-content.json endpoint, gated by an access token. Thanks @arkaigrowth for designing and shipping this!
Dashboard graph layout overhaul (#111)
Replaces dagre with ELK across all structural-style views and reshapes the layer-detail view around folder/community containers that lazy-expand on demand. Fixes the long-standing horizontal-sprawl problem where layers with 50+ nodes rendered as a single ~14000px row.
- Containers: layer-detail nodes are grouped by folder (Louvain community detection as fallback when folders are too flat). Each container renders as a translucent gold-bordered atom with the folder name and child count.
- Two-stage lazy layout: Stage 1 lays out container atoms only (~125ms even at 500 nodes). Stage 2 runs ELK per container on demand — when you click, when you zoom past 1.0, or when search/focus/tour lands a hit inside.
- Edge aggregation: cross-container edges collapse into a single weighted edge with count. Expanding a container inflates them back to file→file. Edges anchored to collapsed containers stay anchored to the container atom so nothing silently disappears.
- Visual overlays: containers light up for search hits (count badge), diff impact (red border), and focus/selection (gold border).
- Keyboard accessible: containers are real disclosure buttons (
role="button", aria-expanded, Enter/Space).
- Performance: dashboard main bundle stays at ~62KB gzipped (ELK split into a parallel-loaded chunk).
Other contributions since v2.3.1
Huge thanks to everyone who improved the project this cycle:
- #95 — @0xnayuta: harden plugin root resolution across install modes.
- #97 — @xiaolai: use
printf instead of echo to pipe TOOL_INPUT into grep.
- #98 — @xiaolai: log skipped invalid gitignore patterns to stderr.
- #103 — @ZebangCheng: fix hero image extension in the Astro homepage.
- #105 — @gustn99: README link refresh (Claude Code plugin).
- #110 — @LukasWana: file permissions on
extract-domain-context.py.
Other improvements
- File double-click also navigates the graph; sidebar composition preserved when reopening the slide-up code viewer.
- DomainGraphView migrated to ELK with LR direction preserved.
- WarningBanner now distinguishes graph data errors (asks your agent to fix the JSON) from dashboard rendering bugs (links to the issue tracker).
Compat
- No graph schema changes. Existing
.understand-anything/knowledge-graph.json files load unchanged.
applyDagreLayout is @deprecated and slated for removal next release.

What's New
/understand-knowledge — Knowledge Base Analysis
New skill for analyzing Karpathy-pattern LLM wiki knowledge bases. Detects raw sources and wiki markdown with wikilinks, then produces interactive knowledge graphs with entity extraction, implicit relationships, and topic clustering across five phases (DETECT → SCAN → ANALYZE → MERGE → SAVE).
Comes with two new agents:
- article-analyzer — extracts implicit knowledge from wiki articles: entities (people, tools, papers), claims (decisions, assertions), and semantic edges (
builds_on, contradicts, exemplifies, authored_by, cites)
- assemble-reviewer — post-merge quality reviewer that recovers dropped nodes/edges, remaps unknown types, and verifies cross-batch consistency
A dedicated KnowledgeGraphView dashboard component provides force-directed visualization with search, tour highlighting, and relationship-typed edge styling.
.understandignore Support
User-configurable file exclusion for /understand analysis:
- IgnoreFilter — runtime filtering with hardcoded defaults (node_modules, build outputs, lock files, binaries) plus layered
.understandignore files from .understand-anything/ and project root
- IgnoreGenerator — auto-generates a starter
.understandignore by parsing your existing .gitignore and detecting project directories
- New Phase 0.5 in the
/understand workflow pauses for user confirmation after generating the ignore file
/understand Pipeline Improvements
- Subdomain graph merging (Phase 0) — merges multiple domain-specific graphs into one unified graph with deduplication
- Batch graph merging — new Python script with ID normalization, complexity mapping, and detailed fix reports
- Incremental updates — structural fingerprinting with
--auto-update / --no-auto-update flags
- Language/framework context injection for architecture analysis
- Expanded review paths — inline validation vs. full LLM review via
--review
Schema & Type Expansion
- Node types expanded from 13 → 21 (added
domain, flow, step, article, entity, topic, claim, source)
- Edge types expanded to 35 covering structural, behavioral, data flow, dependency, semantic, infrastructure, domain, and knowledge relationships
- Type aliases for flexible input (
func → function, doc → document, etc.)
Project Scanner Improvements
- Now handles non-code files (configs, docs, infrastructure, data) with explicit
fileCategory assignment
- Deterministic script-based file discovery with improved language and framework detection
Documentation & Internationalization
- Korean (
README.ko-KR.md) and Spanish (README.es-ES.md) README translations
- Animated showcase GIFs for structural and domain views
- Multi-platform badges (Codex, Copilot, Gemini CLI, OpenCode)
Fixes
- Dashboard URL now includes access token
- Connected edges highlight correctly on node selection
- Stable layout and scoped infrastructure filter in graph view
- Marketplace JSON schema validation fixes
- Edge weight coercion for graph merge scripts
