Murfy

Murple

Freemium

An AI-native online LaTeX editor and Overleaf alternative with unlimited free collaborators, AI paper review, and automatic compile-error fixes.

AI Paper Review: Eight simulated readers go through the draft and three models cross-check each other's findings, returning the critique a venue would write without the accept/reject verdict.
AI Compile Error Fixes: Reads the LaTeX error log and presents the correction as a diff you can accept or reject, instead of leaving you to decode the red output.
Unlimited Free Collaborators: Every plan, including the free Starter tier, allows an unlimited number of co-authors with no per-seat pricing.
Real-Time Co-Editing: Multiple authors edit the same paper simultaneously with comments and track changes, without version conflicts.
Fast Compilation: Claims roughly 2x faster compiles than Overleaf, with a 30-second timeout on the free tier and 5 minutes on Pro.
Diff-Based AI Suggestions: Every AI-proposed sentence change is surfaced as an accept-or-reject diff so the author's voice is preserved.
Full Version History: Roll back to any earlier point in the document; Starter keeps 24 hours of history and Pro keeps the full record.
Template Library: Start from conference, journal, or thesis templates rather than building a preamble from scratch.

Multi-Author Paper Writing: Coordinate a research group on one manuscript in real time without paying per collaborator.
Pre-Submission Review: Run an AI paper review before submitting to a conference or journal to catch unsupported assumptions and missing related work.
Debugging LaTeX Builds: Resolve undefined control sequences and other compile failures from a suggested diff instead of reading the log.
Thesis Preparation: Write a dissertation from a thesis template with full version history and rollback across months of drafting.
Migrating from Overleaf: Move a lab off per-seat Overleaf pricing to a free tier with unlimited collaborators and faster compiles.
Overnight Change Tracking: Catch up on co-author comments and edits through a morning briefing rather than hunting through the document.

Paid

AI visibility platform that tracks how ChatGPT, Perplexity, Claude, Gemini and AI Overviews cite your brand, and ships fixes.

AI Citation Tracking: Continuously samples roughly 50,000 prompts per week across ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews to record where and how a brand is cited.
Per-Engine Visibility Scoring: Reports a composite AI Visibility score plus share of voice and prompts won or lost, broken out engine by engine so declines can be traced to a specific model.
Prompts & Citations Explorer: Lets teams open any tracked prompt and read the actual model answer to see which competitor was named and why.
Brand Entity Analysis: Maps the adjectives each engine associates with your brand versus competitors and suggests reframing plays to change that portrait.
Competitor Intelligence: Tracks rival citation share on comparison and 'alternatives to' prompts, highlighting categories where a competitor dominates.
Prioritized Action Plan: Converts findings into P0/P1 recommendations such as schema additions or comparison pages, each with a time estimate and projected score gain.
Site Audit for AI Parseability: Audits pages for missing entity definitions, structured Q&A data and other signals that prevent models from citing the site correctly.
White-Label Reporting and API: Higher tiers add white-label client reports, SSO/SAML and API access for agencies managing multiple brands.

AI Search Monitoring: Marketing teams track whether ChatGPT and Perplexity recommend their product or a competitor on high-intent category prompts.
Competitive Benchmarking: Brands quantify how much citation share a named rival is capturing on 'alternatives to' and 'best of' queries.
Content Prioritization: Content teams decide which pages to write or refresh based on which prompts are currently missed rather than on keyword volume alone.
Technical AEO Audits: SEO specialists find pages lacking FAQ schema or entity markers that keep answer engines from parsing them.
Agency Client Reporting: Agencies run pooled prompt tracking across multiple client workspaces and deliver white-label AI visibility reports.
Executive Reporting: Operators present a weekly digest showing search clicks alongside AI citation share to explain traffic shifts leadership sees.
