Inkwell

Inkwell is an AI-native writing IDE whose current production surface, Plot, is built specifically for screenwriting. Rather than treating a screenplay as styled prose, Plot models scene headings, action, characters, dialogue and other screenplay elements as structure. The editor supports 16 screenplay element types, semantic scene/line changes, named save points, alternate draft lines and production-oriented revisions.

The clearest product distinction is its version-control model. Save points are immutable named snapshots; draft lines are parallel versions analogous to branches; semantic diffs show scene and dialogue changes in writer-readable form. This addresses a real screenwriting workflow problem: multiple near-identical FDX files and difficulty tracking which changes belong to which round of notes.

AI is implemented as reviewable skill passes rather than only a chat box. Dialogue, tone and other craft passes can propose line-level edits; continuity and coverage-style skills can surface findings. Inkwell states that nothing is applied automatically: each change remains tied to the underlying scene/line and must be accepted or rejected. Hosted skill passes are available, while bring-your-own-key configuration lets users run supported AI against their own provider account.

Plot imports and exports Final Draft FDX and Fountain and exports industry-formatted PDF. Fountain and PDF export are available on every plan; FDX export begins on Writer. The current browser product also includes real-time collaboration and production workflows. The site says desktop and Apple apps are in active development, so the present core experience remains browser-first.

Inkwell also exposes free browser-only screenplay utilities for pacing, breakdowns, draft comparison, FDX inspection, story mapping and formatting validation. These tools state that local screenplay parsing happens in the browser without account/upload, a useful privacy property for those specific utilities.

Canvas, a broader long-form document editor sharing the same version-control and AI substrate, remains early access/beta rather than the mature basis for this review. The review therefore centers on Plot. ¹²³⁴

Inkwell has a permanent Free plan at $0. It includes the full screenplay editor, recent save-point history, two draft lines per screenplay, 20 AI skill passes per month, PDF/Fountain export and community support.

Writer is $19 per month. It raises limits to ten projects and ten draft lines per screenplay, provides 200 AI skill passes per month, complete semantic version comparison, FDX export, worktrees/custom skills, production reports, collaboration and stronger AI models.

Pro is $39 per month. It adds higher AI quotas, Sonnet/Opus access, custom skills, worktrees, production reports, revision colours, production-draft locking and collaboration with up to five people. Team is $39 per seat per month and adds real-time shared workspaces, shared skill libraries, audit logs, role-based permissions, pooled AI credits and free viewer seats. Enterprise is custom-priced with SSO, deployment options, API access, SLA and dedicated support.

The pricing structure is clear and the free plan is unusually functional for a screenwriting product. Value depends less on raw AI quota than on whether a writer actually uses save points, semantic diffs, alternate takes and production workflow enough to replace separate tools or manual file-versioning. ⁵

First-party product documentation is detailed. Inkwell clearly separates AI suggestions from accepted draft text, supports BYOK, promises user ownership of screenplays/version history, and emphasizes export portability. Those properties reduce lock-in and make AI intervention more inspectable than a generic generate-and-replace workflow.

The major evidence problem is entity confusion. Capterra currently lists a product called Inkwell with $9.95–$19.95 publishing plans, books/storage limits, scholarly/long-form writing features and an AI Copyeditor. That is not the inkwell.software screenwriting IDE reviewed here. It is therefore an exact-name but wrong-product match and is explicitly excluded from rating and pricing evidence. Similar generic Inkwell search results must be treated the same way unless the product surface matches Plot at inkwell.software.

No mature exact-product user-rating corpus, independent comparative review or controlled test of Plot’s AI passes, FDX round-trip fidelity, collaboration reliability or production workflow was found. This limited independent evidence lowers confidence in performance claims beyond the documented product surface.

Some capabilities are also still maturing. The current homepage states that breakdown reports and revision colours are live on Pro while printed A-pages are on the roadmap, and Canvas is early access/beta. Production teams should distinguish currently shipped functions from planned parity with mature incumbents. ⁶

Inkwell is best for screenwriters who already understand the pain of multiple draft files and want a structured alternative to manual version naming, and for writing rooms that benefit from shared drafts, semantic change review and controlled AI passes. It is particularly compelling for users who need FDX/Fountain portability but want a browser-native collaborative workflow.

It is less compelling for writers whose production office mandates a mature incumbent’s native workflow end to end, users who need offline desktop/mobile-first operation today, or buyers who require a large independent review corpus before changing core writing software.
