A collaborative authoring platform for long-form fiction. Build worlds, draft chapters, and revise together — with co-writers and a partner that actually reads your manuscript.
Starts at $6/mo. No credit card to try. Self-host free.

“what color were her eyes in chapter 2?”
Writers lose hours every week hunting details they already established. DAN remembers them for you — every chapter, every character, every promise you made in Act 1 that needs to pay off in Act 3.
Four tools, each doing one thing well. Together they make the long-form work tractable.
Every character, location, and plot point tracked across 80,000 words. Ask "what color were her eyes?" — get an answer, with chapter and scene citation.
Daneel reads a full chapter and flags continuity breaks, pacing dips, unfulfilled setups, and character voice drift. Not autocomplete — actual close reading.
Whole-manuscript revision runs. Pick the pass (tighten prose, punch up dialogue, fix POV drift). Run overnight. Review diffs in the morning.
Drafting pane on the left, reference pane on the right. Your Story Bible, previous chapters, and Daneel chat all stay in view while you write.
Team is $6/month for up to 5 collaborators (solo writer + crit group). Swarm is $20/month for up to 25 (writing collective or classroom). Or self-host for free on your own server — same features, no caps.
Paid tiers include a bundled fast-task allowance each month — enough for everyday drafting and analysis work. For heavier premium work, bring your own provider, or top up with credit packs. No surprise bills.
Yes. DOCX, EPUB, or Markdown. Your prose is yours. Export is built into the editor; no vendor lock-in.
Paid cloud stores your work on our infrastructure (encrypted at rest). Self-hosted keeps everything on your own server — your prose never leaves your machine. Either way, we never train models on your writing.
Yes. Docker image is public (docker pull ignusvm/dan). No collaborator caps, free for personal and internal use. See the download page for details.
