Showspring

AI production studio for episodic podcasts and YouTube shows. Built around a show bible, not a prompt.

Early access · 2026
02 · The problem
The gap

AI tools make clips.
We make the next episode.

Clip tools Stateless generators. One prompt in, one clip out. Episode two doesn't know episode one existed.
Showspring Stateful studio. Characters, voices, formats, callbacks: all persistent. Episode 47 belongs next to episode 1.
03 · The insight
The insight

A show needs memory.

Clips don't have any. Every AI video tool on the market is amnesiac. It forgets your characters, your voice rules, your running jokes the moment you hit generate. That's fine for a one-off. It's fatal for a series.

04 · The primitive
The primitive

The show bible is a first-class object.

Every generation step reads it. Every episode writes back to it. A single source of truth for everything that makes your show your show.

Characters
Names, personalities, visual refs
Who's in the cast. How they speak. What they look like across every scene.
Voices
Per-character ElevenLabs IDs
Voice clones or voice picks, pinned to characters. No voice drift between episodes.
Formats
Segment rules & pacing
News-desk tempo, quest-narration pacing, sign-off lines. Structural DNA for each segment.
Canon
Running jokes & callbacks
The things you've established: the pepperoni heat map, Kevin the Cat, the Fire Hydrant Gazette. Writer-room memory.
05 · Progressive, not upfront
How you start

You don't author a bible.
The bible writes itself.

Start with one character and one format. Make episode one. The bible fills in from what you actually make: your first concept seeds the show identity, every saved character writes its own section, and published episodes feed lore back in. By episode two, the tool already knows your show.

06 · The outcome
The proof that it worked

Episode 47
sounds like episode 1.

Not because you wrote it the same way. Because the system remembered everything in between.

07 · Pipeline
The pipeline

Six steps. One workspace. One show bible through all of them.

01
Idea
Frontier models pitch head-to-head. You pick.
02
Script
Bible-aware dialogue. Characters stay in voice.
03
Voice
Per-character ElevenLabs, with preview.
04
Visuals
Multiple engines, takes per clip, one look.
05
Edit
Multi-track timeline. Audience reactions.
06
Publish
One click. Your channels, your metadata.

Each step reads and writes the bible. Every episode makes the next one smarter.

08 · Step 01
Step 01 · Idea

Eight pitches. Two judges.
You pick the winner.

In full production, four themes per session. On every theme, Claude Opus writes head-to-head against a rotating flagship challenger: Gemini 3.1 Pro on one, Grok on the next. Judges score the field, and the final call is always yours. Every pitch is bible-aware from the first token.

  • Bible-aware pitches: characters act in-character and pitches stay inside canon.
  • A standing bake-off: every bake-off quietly scores the writers against each other, so we can see which models earn their seat.
  • Second verdict: an optional Grok judge keeps the first judge honest.

Step 02 · Script

Dialogue that stays in character,
line after line.

Scripts inherit the show bible automatically: recurring jokes, speech rhythms, segment-specific rules. Claude Opus leads the writer bench, with Grok, Gemini and Gemma alternatives. Edit any line in place, or hand feedback to the writer and it rewrites just the affected clips.

  • Targeted rewrites: touch a few clips without blowing up the scene.
  • Versioned drafts: compare any two versions, roll back, or rewrite from collaborator feedback.
  • Voice-gated generation: characters without assigned voices don't get dialogue.
10 · Step 03
Step 03 · Voice

Per-character ElevenLabs voices,
with controls.

Voice IDs live in the bible. The readout step plays every line in every character's pinned voice before anything renders. Share-for-review links let collaborators sign off without touching the app.

  • Pinned voice per character: no drift between episodes, ever.
  • Preview before render: play any line, or the whole episode readout, before it touches the pipeline.
  • Share-for-review: private link, no login required, with star ratings and comments.

Scenes panel with cast-locked keyframes, dialogue, and an editable scene description for each clip
Step 04 · Visuals

Locked to your cast.
One consistent show.

Veo renders through the official API. Every still is generated against the cast's reference images and visual bible, and every clip animates from that locked frame.

  • Cast-locked frames: up to three reference images per character, injected into every scene.
  • Takes & version history: render multiple takes per clip, compare side by side, flip the active one.
  • Per-clip regen: fix one shot, leave the rest alone.
12 · Step 05
Step 05 · Edit

Multi-track timeline,
ready to finish in DaVinci.

Trim, reorder, layer audience reactions, music beds and SFX. Render the finished episode in-app, or hand a frame-accurate timeline to your NLE of choice.

  • Audience reaction track: 13 reaction types plus a live room bed; the news desk runs a Weekend Update dry-desk profile.
  • Lane-packed timeline: overlapping cues stack into real lanes, in the app and in the export.
  • Resolve handoff: FCP7 XML, an OTIO bundle, or the native Resolve panel. Same timeline, every format.

Step 06 · Publish

One button.
Your channels, your metadata.

AI-generated titles, description, tags and thumbnail. Each show connects its own YouTube channel and chooses its platforms. The master stays yours.

  • Three title shapes: search-led, curiosity-led, character-led. Pick one or regenerate.
  • Per-show channels: every show publishes to its own brand account and its own platform set.
  • Ships to your feed: your channels, your audience, your master files.
14 · Shorts
Beyond the episode

One episode becomes
a week of Shorts.

A dedicated Shorts lane lives next to the episode pipeline: pick the strongest beats, recut them vertical, and schedule the week on the unified calendar. Captions are burned in from the actual spoken audio, a few words at a time.

  • Channel-tuned ideas: an analytics loop mines what worked on the channel and feeds proven hooks and pacing rules back into the prompts.
  • Word-timed captions: transcribed word-level from the real audio, then burned in.
  • Scheduled cadence: a calendar of slots, with same-day mirrors to Instagram and X.

15 · Collaboration

Not a solo sport

Your writers' room
can watch live.

Director Copilot gives trusted collaborators a live view of an episode build: rate pitches, comment on storyboards and takes, react to script lines. Everything lands in one in-app inbox, and ideas, scripts, readouts and scenes each get their own share link.

  • Reviewer rooms: storyboard, take and script feedback with per-clip, timecoded reactions.
  • No-login share links: private 7-day tokens, all revocable from Settings.
  • Guest voices: guests audition a shortlist and submit their voice pick from a public link.
16 · The workspace
The workspace

One studio.
Many shows.

Every show is its own world: cast, bible, canon, connected channels, even its own Drive folder. Work on two shows in two browser tabs without bleed. Deleted shows rest in a 30-day trash, not a void.

17 · Architecture
Under the hood

Right model, right step.

No single-provider bet. Each pipeline step routes to the model that's best at it, and falls back gracefully when a provider is down, slow, or pricing-hostile.
