Anyrow
Anyrow
Anyrow is an AI-native operational database. It turns documents, images, audio, video, email, and other databases into typed rows inside a live relational database — one schema end to end. Rows arrive four ways: upload a file, migrate from a competitor (Parseur, Docparser, Airtable, Notion, Sheets, Postgres), bidirectional sync with Sheets / Airtable / Notion / Postgres, or direct CRUD via dashboard grid or REST/SDK. Use all four, any one, or mix per table. Every row keeps its source — page, bounding box, or audio timestamp. Corrections compound into better extractions over time, per-customer, never shared. Typed columns, relational fields (link / lookup / rollup), entity views, full-text search, natural-language queries, row-level audit log, soft deletes, smart caching, SSE streaming, typed SDKs (TypeScript, Python, Go, Rust), webhooks, OpenAPI spec. Time to first row: under 60 seconds. Free tier available.Starting Price: $49/month/user -
