Bolt and Aeira from Sparcle

Live

A self-hosted AI workspace for regulated industries that gives a ChatGPT-like experience without sending data outside your own infrastructure — for enterprises that must stay on-prem or air-gapped.

Works offlineSelf-hosted
What to know▼
How it works
Pairs Bolt, a local-first AI workspace that runs on the user's own machine, with Aeira, a governed retrieval and policy layer, so enterprises get a ChatGPT/Copilot-style experience while everything runs inside their own trust boundary (on-premises, VPC, or air-gapped).
What's different
You bring your own LLM (hosted frontier model behind your own key, a model in your VPC, or a local open-weight model Sparcle auto-detects) and PII is masked at the LLM boundary so the model only sees redacted context.
Best for
Regulated enterprises (subject to HIPAA, GDPR, DPDPA) that need AI productivity tools without sending data outside their infrastructure.

kysigned

Live

Lets you e-sign a document by forwarding it via email, using your provider's DKIM signature as proof instead of a signing company; open source, self-hosted or hosted, pay-per-document.

No sign-upWorks offlineOpen sourceNo subscription
What to know▼
How it works
Forward a document to the service and type 'I sign this document' — your email provider's existing DKIM signature becomes the proof of signing, bundled into one self-contained file anyone can verify offline in a browser.
What's different
No third-party signing company is trusted with the signature — the proof relies entirely on infrastructure (DKIM) that already exists and would still verify even if this service disappeared.
Pricing
4 free signatures, then $0.25 per document, no subscription. Open source (Apache-2.0) — self-host or use the hosted version.
Best for
People who need a lightweight, verifiable e-signature for occasional documents without paying for a full e-signature platform subscription.
Watch out
The provider states it never holds a signing key and can't forge or alter documents — that's the product's own security claim, not independently audited.

Aiden

Live

A physical open-source USB device that watches your screen and can operate your phone or computer by voice, entirely offline with zero data collection. Built for makers and privacy-focused tinkerers.

Works offlineOpen sourceSelf-hosted
What to know▼
How it works
A physical USB device that plugs into any phone or computer, watches the screen over HDMI, and sends taps and keystrokes over USB HID to operate real apps the same way a person would — no app install, jailbreak, developer mode, or API required. It captures the screen, sends it to an AI model of your choice, decides the next action, and repeats until the task is done; voice mode runs on-device.
What's different
Works one layer below software integrations, so it can operate any app you can see and tap, including ones with no API or accessibility layer.
Best for
Makers and privacy-focused users who want to automate phone or computer tasks entirely offline without granting an app API access.
