FillApp vs UseAgent

FillApp is a paid AI agent for completing web and PDF forms with saved information or custom instructions, and for automating browser workflows in existing sessions. Fill Mode handles forms, Agent Mode performs multi-step work across tabs, and Assist Mode summarizes pages, PDFs, and images or answers questions about them. Supported fields include text, dropdowns, checkboxes, dates, and long text blocks. Saved datasets become reusable snippets inserted with @SnippetName. The agent can request confirmation before risky actions such as submitting forms or deleting data. Named integrations include Google Forms, Microsoft Forms, Salesforce, HubSpot, Jotform, Airtable, Workday, Greenhouse, Atlassian, and ServiceNow. FillApp is available as a browser extension and web app. It says page content is accessed when a conversation or agent engagement starts, not monitored in the background. Prompts and needed context may be sent to OpenAI and Anthropic. Chat sessions clear after the session, while account and snippet data remains until deletion or one year of inactivity. Starter costs $14.99 a month; Pro costs $29.99 a month. A 7-day trial is listed.

UseAgent provides AI coworkers that research, prepare reports, and handle follow-ups using company knowledge and connected tools. Teams can add documents and instructions, review proposed knowledge before sharing it, and optionally use team memory. Agents can run recurring workflows hourly, daily, or weekly and post results to Slack. They can also create editable DOCX, XLSX, and PPTX files for export to Office or PDF. The cloud plan lists Chat, OpenCode, Claude Code, Codex, and Pi as agent engines. Integrations include GitHub, Slack, Linear, Gmail, Notion, HubSpot, Google Drive, MCP servers, and PostgreSQL. GitHub access currently supports reading pull requests, issues, and commits; write operations are marked as coming soon. Agents work in isolated Linux environments, and teams can inspect saved requests, tool calls, approvals, and results. Users can require approval before sensitive actions. Cloud and self-host plans are free, but users supply their own AI provider keys and providers bill for model usage and computer time. Bots and routines are planned for self-host v0.0.4, while the public repository is at v0.0.3.
