HASH

What HASH is

HASH is an open-source platform for building a continuously updated model of an organization’s information. It combines a knowledge graph with a process graph, then uses that model for analytics, workflow automation, what-if simulations, AI agents, and fine-grained access governance. It can bring in data from connected applications and structured sources, identify entities in unstructured information, and passively collect selected information from the web. Its bitemporal graph records both when information was added and when a decision took place, so users can inspect past states and provenance without replacing earlier records.

Flows combine triggers, actions, filters, and waits, and can run manually, automatically, or programmatically. Agents can answer questions and take actions. The integration directory includes Slack, Google Drive, Gmail, Notion, GitHub, SAP S/4HANA, Snowflake, and Postgres. Two-way sync is available where supported; some services allow only read-only sync or one-time imports. HASH also offers a browser extension for gathering selected browsing information, giving agents access to websites, and launching flows from a page. It is available through the web, API, extension, or self-hosted deployment. HASH was founded in 2019 and is based in London, Berlin, and New York.

Who it suits

HASH suits organizations that want to connect structured and unstructured information to analytics, automation, simulations, or AI agents. Its self-hosted option may suit advanced users with technical expertise, while its web and extension options provide other ways to use the platform.

Limits

The free plan includes 10GB of storage, 50 entities per manual scraping job, and one entity type per job. Plus costs $20 per month billed annually, or $30 per month billed monthly, and allows 1,000 entities per manual or passive scraping job and five entity types per job. Team costs $30 per user per month billed annually or $45 monthly, requires at least two billed members, and includes one concurrent active scraping job.

Getting started

1. Visit https://hash.ai/.
2. Choose the web product, API, browser extension, or self-hosted deployment.
3. For self-hosting, consult the guide and prepare for the required technical work.
4. Select the free plan or a paid plan; Plus starts at $20 per month billed annually.
5. Connect available data sources and build your organizational model.

Verdict

Choose HASH if your organization needs a connected information model for workflows, analytics, simulations, or agents, with historical states and provenance. The free plan provides a starting point; paid plans offer larger scraping limits and storage. Look elsewhere if you need self-hosting without technical expertise or a service that provides two-way sync across every integration.
