SupaSubmit
What SupaSubmit is
SupaSubmit fills browser forms, Word tables, and Excel sheets from a plain-language task description. It maps the instruction to the form or table structure, then prepares values for review before writing. Prompts can be reused across browser forms, Word, and Excel, while reusable profiles and routines support repeat work. Its Chrome extension detects standard browser controls, dropdowns, checkboxes, and multi-step sections without per-site templates. Unsupported custom controls remain unchanged and are reported for review. Users review mapped values before consequential actions, and existing non-placeholder Word content is skipped. SupaSubmit also offers Microsoft Word and Excel add-ins, with listed platforms including extension, iOS, macOS, web, and Windows. Named use cases include operations and procurement, HR and employee onboarding, and vendor, customer, and compliance forms. A free plan is available. Paid plans start at $9/mo for Basic, which includes 1,000 credits monthly and about 100 forms monthly; Pro is $19/mo and Enterprise is $499/mo. Word fill plans send instructions and relevant table content over HTTPS to SupaSubmit's API, where OpenRouter and the selected AI model provider process them.
