60+ HR tools in one tiny desktop app. Offer-letter & HR-email generators, payslips, region-aware payroll, salary & tax calculators (India · US · UK · Europe · UAE · Saudi · Nigeria · South Africa), and classroom tools — 100% offline and local-only. No accounts, no cloud, no telemetry; since v2, the app refuses to talk to anything beyond your machine.

v2 turns hrToolkit's privacy promise into code the app enforces, built for HR teams working with real employee data:
- Cloud AI removed. AI Assist now runs only on a local model via Ollama; the Rust backend refuses any endpoint that isn't
localhostand upgrading scrubs any previously stored API key. - Hardened Content-Security-Policy — no remote origins, no
unsafe-eval, no dev-server leftovers in release builds. - Narrower file access — PDF saving is scoped to Desktop/Documents/Downloads only.
- Android: OS backup of app data is disabled, so saved HR profiles never land in Google Drive.
- Honest docs: SECURITY.md now spells out exactly what stays on your machine — and what your OS does around it.
And in v2.1:
- 🔐 App Lock — optional passphrase encryption at rest (AES-256) for saved profiles; asked once per launch, unrecoverable by design.
- 📱 Mobile-responsive UI — the sidebar becomes a drawer on phones and layouts fit narrow screens, so the Android build is genuinely usable.
- 🔏 Stable APK signing — Android releases now update in place instead of requiring uninstall/reinstall.
Full details in the CHANGELOG.
A free, open-source alternative to scattered web tools and paid HR software — for recruiters, HR teams, payroll admins and teachers who want fast, private utilities without sign-ups or subscriptions. Because it's local-only, it's a natural fit where employee data must not touch third-party servers (works councils, GDPR-conscious teams, air-gapped or on-premise environments).

- 🔒 Private & offline — runs entirely on your computer; no accounts, no telemetry, no internet required.
- 📝 Generate HR letters & emails — offers, appointments, terminations, experience/relieving letters, and more, in formal / modern / friendly tones with one-click Copy and Save as PDF.

- 👤 People-first — save a company & its people once, then auto-fill every document.
- 🎨 Beautiful & fast — Notion-calm × Obsidian-dense UI, full dark mode, and a
⌘Kcommand palette. - 🤖 Optional AI & agentic use — draft with a local model (Ollama, strictly on-device), and an MCP server to drive the toolkit from agents.

Grab the latest build for your OS from the Releases page:
| Platform | File |
|---|---|
| macOS | .dmg (Apple Silicon & Intel) |
| Windows | .msi / .exe |
| Linux | .AppImage / .deb |
| Android | .apk (sideload) — early / experimental, see below |
Heads-up — the apps are unsigned (no paid code-signing certificate yet), so your OS may warn on first launch:
- macOS: right-click the app → Open → Open (or
System Settings → Privacy & Security → Open Anyway).- Windows: More info → Run anyway on the SmartScreen prompt.
- Android: enable Install unknown apps for your browser/file manager, then open the
.apk.ℹ️ Android: responsive since v2.1 — the sidebar becomes a drawer and layouts fit phone screens. Desktop remains the richest experience (⌘K palette, keyboard-first), but the APK is now genuinely usable day-to-day.
It's safe — the source is right here and the app is offline by default (the only optional network path is opt-in AI Assist). Prefer to build it yourself? See Develop.

Every letter/email comes in formal, modern and friendly tones, with live preview,
one-click Copy and a real Save as PDF (generated on-device, works offline).
Calculators show a clear breakdown and a ⌘K palette jumps to any tool.
⚠️ Statutory calculators (tax, PF, gratuity, end-of-service) are estimates. Figures use FY 2024-25 rules and vary by state/emirate/contract and your declarations. The app shows this disclaimer in-product too — always verify with an official source or payroll team before relying on a number.
hrToolkit is offline by default, and since v2 AI Assist is strictly local: the only
backend is a model running on your machine via Ollama (e.g.
llama3.1). There is no cloud provider and no API key — the app refuses any endpoint
that isn't localhost, so drafted HR text cannot leave the device.
Once enabled (Workspace → AI Assist), a ✨ Draft with AI box appears in every letter/email/payslip — type a one-line brief and it fills the fields. The request is made by the app's Rust backend (not the web layer), which enforces the localhost-only rule.
MCP server — hrToolkit ships an MCP server (mcp/)
that broadcasts its tools to agents (Claude Desktop, Claude Code, …): discover every tool,
generate documents and run calculators programmatically, all locally. Run bun run mcp;
see mcp/README.md.
hrToolkit v2 is strictly local: no cloud AI, no accounts, no telemetry, and a
Content-Security-Policy with no remote origins so the webview can't phone home. All
data stays in localStorage on your device. The only optional network path is opt-in
AI Assist (above), which the Rust backend restricts to localhost — it refuses remote
endpoints outright. On Android, OS backup of app data is disabled so your HR data
never lands in Google Drive. To report a vulnerability, see SECURITY.md.
bun install
bun run tauri dev # run the desktop app
bun run tauri build # produce a distributable bundle
bun run build # frontend-only build + typecheck
bun run test # run the calculator/formula test suite (vitest)Requires Rust and Bun (or npm).
Architecture is data-driven, so adding a tool is a small, local change:
src/data/templates.ts— letter / email / payroll templates (pure data)src/data/calculators.ts— declarative calculator specs (inputs + a purecompute())src/data/catalog.ts— the master navigation catalogsrc/components/custom/*— richer interactive tools (JD matcher, GPA, password gen)
See docs/ARCHITECTURE.md and the design language in DESIGN.md.
Contributions welcome — new letters, calculators, regions and fixes. Read
CONTRIBUTING.md. Statutory formula changes should cite a source
and ship with a test in src/data/calculators.test.ts.
Is hrToolkit really free? Yes — free and open-source under the MIT license, no paywalls.
Does it work offline? Yes — always. Since v2 the app cannot talk to the internet at all: the only network feature, opt-in AI Assist, is restricted to a local Ollama model on localhost.
Which countries are supported for payroll? India, the US, the UK, Europe (Germany, France, Netherlands, Ireland, Spain), the UAE, Saudi Arabia, Nigeria and South Africa. Generic calculators work for any currency/region.
Are the tax/payroll numbers official? No — statutory calculators are estimates using FY 2024-25 rules and are labelled as such in-app. Always verify with an official source.
Where is my data stored? Locally, in the app's storage on your device. Nothing is uploaded — there is no server to upload to.
Is it safe for real employee data / GDPR? The app itself never transmits or collects anything, which removes the usual processor/sub-processor questions — your data stays on hardware you control. On shared machines, turn on App Lock (v2.1+): it encrypts saved profiles at rest with AES-256 under a passphrase asked once per launch. See SECURITY.md for the full threat model.
Can the AI feature leak my data? No. Since v2 the only AI backend is a local Ollama model; the app rejects any non-localhost endpoint at the Rust layer, disables redirects and ignores system proxies. There is no API-key field anymore.
Is this an alternative to paid HR software? For documents, letters, payroll math and quick calculators — yes, that's the point: one free desktop app instead of a subscription or a dozen ad-filled web tools. It doesn't try to be a full HRIS (no attendance database, org chart or leave workflow).
Does it run on a company laptop without admin rights / behind a proxy? Yes — it's a normal user-space app that needs no network at all, so proxies and firewalls are irrelevant to it.
