Every idea.
Every agent.
One home base.
Keep each project’s plans, docs, brand assets, and progress together—from first spark to launch and beyond. Give your agents, teammates, and clients a shared place to understand the work and move it forward.
Connect Claude Code · Codex · Cursor · ChatGPT · Grok
Nothing is saved until you sign in. Every item links to the passage it came from.
Switch agents. Keep your decisions.
Build with Claude Code, Codex, Cursor, Lovable, or by hand. Hark keeps the thinking, the plan, the progress, and the proof in one place.
An agent working on V-004 can't read or write V-009 without an explicit switch — and blocked attempts are logged.
If a session goes quiet, Hark drafts the handoff from what actually happened; the next agent sees it first.
Decisions and state changes proposed by agents wait for your accept or reject; they never enter the brief or your public project page unreviewed.
Phase, next action, last decisions, blockers, non-goals — with the full project page on request.
With export on, Hark commits .hark/HANDOFF.md, .hark/DECISIONS.md, and an AGENTS.md block, so the brief survives even if Hark is unreachable.
Every entry carries the client that wrote it, so you can always see which agent said what.
From spark to shipped, in four moves.
Drop any idea in seconds. It lands in the Vault.
Business, build docs, branding — with a project page score that shows what's missing.
Move it through the pipeline: Vault → Recon → Blueprint → Fabrication → Live.
Publish a project page, open a client or investor room, or connect any agent through MCP.
Works with Claude Code, Codex, Cursor, ChatGPT, Grok — or no AI at all.
See the full walkthrough →Every idea gets a stage.
Move an idea from a raw spark to something live — an app, a newsletter, a service, a client build. Nothing gets forgotten in the middle.
The full stack of every idea, in one place.
Every project holds its business thinking, build docs, and brand assets — with a project page score that tells you what's still missing.
Thesis, problem, audience, model, competition, risks, next actions. The thinking that usually lives in a notes app finally has a home.
Approach, stack, scope, notes. Optional AI context doc for anyone building with Claude Code or ChatGPT.
Name, domain, palette, typography, logo drafts, and the files behind them — all attached to the idea, not floating in a folder.
Your ideas. Your team's. Your clients'.
Workspaces are separate drawers on one dashboard. Keep your personal side projects distinct from your co-founder's, and from the builds you're doing for someone else — without juggling accounts.
A private drawer for your own ideas — the ones nobody's seen yet.
Invite collaborators, assign roles, keep the pipeline in sync.
One workshop per client. When it's done, hand over the ZIP.
Pick your workshop.
Every new workshop starts with a free 14-day trial — no card. Solo starts on Builder, teams on Studio. Annual plans get two months free.

Building with AI? Plug Hark in.
Connect Hark to Claude Code or ChatGPT via MCP — capture ideas mid-session and keep specs and stages in sync as you ship. Optional; everything works without it.
Your ideas are yours. We never train on your data, we never sell it, and we never hand it to third-party model providers for training. Read the Privacy Policy.
Shipping every week.
Trust levels, Autopilot and one-click session approval
Each project picks how much agents approve on their own (Standard, Relaxed, or a 24-hour Autopilot per agent tool), marked Auto-approved everywhere. Decisions are never auto-approved, and anything that clashes with one waits for you. "Accept all from this session" clears the rest in one click.
CLAUDE.md sync can't overwrite your work
Before syncing, Hark shows both copies side by side and keeps a version history you can restore from. Repeated Current state items now merge into one.
Sign-in is Google or email
GitHub sign-in is gone because the sign-in service doesn't support it. Linking repos, repo activity and the .hark/ export work exactly as before.
