FillApp vs Muse

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.

Muse is a personal AI agent for handling tasks and projects and turning longer-term goals into action plans. It can keep working after the app closes, then return when something changes or it needs approval. The agent can browse websites, fill forms, complete transactions, and create documents, PDFs, web pages, and interactive artifacts. Its small-business page lists connections to services including Asana, Canva, Dropbox, Figma, QuickBooks, Notion, Shopify, Slack, Stripe, Zoom, and social platforms. Muse requests approval for sensitive actions such as sending email or making purchases, and displays an audit trail of activity and planned actions. Users can choose connected apps and access levels, disconnect services, opt out of model training, or ask Muse to forget specific information. It runs on a dedicated cloud virtual machine, with a separate Sentinel controlling connector actions and network access. The free plan has a periodically refreshed usage limit. Power costs $20 a month and Maximum costs $100 a month. Subscriptions are in limited testing and not available everywhere; Muse for Small Business is available to people in the US and Canada who are 18 and over.
