AI-generated client portals with intake forms, service packages, and project updates \u2014 so freelancers look polished without the admin overhead.

A fast web tool to mark up screenshots for bug reports, tutorials, and docs. Add arrows, boxes, blur sensitive info, and numbered steps without leaving your browser.

Paste a .env, yaml, or toml config and EnvScan flags leaked secrets (keys, tokens, passwords), insecure settings, and gives a remediation checklist mapped to common weakness types.

Paste a list of endpoints and get a Markdown reference with request examples and auth notes. For devs shipping internal tools who would rather not write docs by hand.

Describe an endpoint and get a mock API spec - OpenAPI 3, Postman, or raw routes - with realistic sample responses so your frontend team can build before the backend is ready.

Paste a sample JSON object and get a JSON Schema (draft 2020-12), a plain explanation of required fields, and the validation rules your API should enforce.

Turn a plain-English description into a correct regular expression for your language, with a part-by-part explanation and edge cases called out.

Turn a question into a correct SQL query with a plain-English explanation \u2014 for analysts and founders who would rather not hand-write JOINs.

Paste JSON or CSV and TypeGen infers clean TypeScript interfaces (or a Zod schema), explains its assumptions, and flags ambiguous fields you should double-check.
