SupaSubmit
What it is
SupaSubmit fills browser forms, Word tables and Excel sheets using a task written in plain language. It maps instructions to the form or table structure and prepares values for review before writing them. Prompts, profiles and routines can be reused for recurring work across supported formats. Its Chrome extension detects standard browser controls, dropdowns, checkboxes and multi-step sections without per-site templates. Unsupported custom controls remain unchanged and are flagged for review. Users review values before consequential actions, and the Word workflow skips existing content that is not a placeholder. SupaSubmit also offers Microsoft Word and Excel add-ins. Its listed use cases include operations and procurement, HR and employee onboarding, and vendor, customer and compliance forms. A free plan is available. Basic costs $9/mo and includes 1,000 monthly credits, about 100 forms per month, web, Word and Excel filling, and email support. Pro costs $19/mo; Enterprise is $499/mo and offers offline or air-gapped deployment, on-premises or private cloud installation, infrastructure-resident data and dedicated deployment support. Word fill instructions and relevant table content are sent over HTTPS to its API for processing by OpenRouter and the selected AI provider; the endpoint does not intentionally retain that content.
