Amplitude vs ScreenplayIQ

ScreenplayIQ is a single-purpose analysis engine for scripts. Feed it a draft and you get logline and synopsis generation, similar films and TV comparisons, story points, full assessment and theme breakdowns, plus — on character-inclusive packages — character synopses, visual character representations, and emotional journey charts. An optional proofread add-on highlights issues inline and recommends fixes, and packages are customizable by depth. Scripts sit in secure siloed storage with WGA-compliant handling, and analyzed stories are not used to train LLM models.

Amplitude is a general-purpose product platform. Its surfaces are behavioral: cohorts, funnels, conversion drivers, session replay with event and network context, heatmaps and zoning insights, action guides and surveys. On top sit experimentation (A/B/n tied to feature flags and cohorts, plus visual web testing with version history and a custom code editor) and feature management with unlimited flags and flag-level access controls. The AI layer is the differentiator: a Global Agent that queries everything Amplitude knows in natural language, Agent Analytics for measuring AI-agent experiences against retention and revenue, AI Feedback that turns user comments into cohorts, and an MCP server that surfaces insights inside Claude, Cursor, and other Sider and editor clients.

Both are AI-assisted, but the inputs differ entirely: one reads narrative text, the other reads event streams from shipped software. There is no feature overlap a buyer could arbitrate.

ScreenplayIQ is paid-only with no free tier, and the meter is the script itself. Page-length-based pricing applies to TV and feature scripts, and cost rises with package depth — Story Analysis (logline, comparables, story points, synopsis), Story + Character (character synopses, visuals, emotional journey charts), and Full Evaluation layering on more. Proofreading is a separate add-on, and packages are customizable, so an occasional writer pays per draft rather than for idle months. That structure suits producers triaging a stack of scripts or an agent checking whether a client's draft is ready to send.

Amplitude inverts this: freemium, with every plan including the full platform and unlimited seats. The scaling axis is events — once teams outgrow Free they commit to event-based Growth or Enterprise pricing, which is why pre-seed teams with no instrumentation budget are explicitly a poor fit. Recent releases tighten operational control rather than change the model: scheduled experiment stops (Sept 2026), cookie consent management for Web Experiment (Aug 2026), consolidated MCP endpoints on the Platform, and a release aimed at getting the correct event defined on the first try. Practically, ScreenplayIQ cost is countable per deliverable; Amplitude cost is a function of volume, seats staying free but events not.
