The record

What it does: Chalkboard turns a topic into a narrated explainer video by scripting, fact-checking, generating Manim animation code, synthesizing narration, and rendering an MP4.
Automated pipeline: The pipeline has separate stages for scripting, verification, animation, visual QA, and rendering, with retry logic when a stage fails.
Fact-checking: A verifier annotates numerical claims, dates, and causal statements and rewrites claims that do not hold up.
Visual QA: After rendering, Claude reviews sampled frames for overlapping text, off-canvas elements, unreadable contrast, and obscured labels.
Video assets: Each video can include an SRT caption file, embedded chapter markers, a YouTube chapter list, and a source script.
Customization: Users can configure audience, tone, template, visual theme, narrator, and effort level.
Integrations: The self-hosted project documents Claude, Manim, ElevenLabs, Kokoro, and OpenAI as pipeline or narration components.
API: The hosted API supports bearer authentication, idempotency, signed webhooks, and test-mode keys; hosted access requires a beta invite.
Self-hosting: The project is MIT licensed and can run locally through its open-source CLI using the user's own Claude key.
Security: The homepage says the pipeline is sandboxed via Docker.
Data controls: The pricing page says account holders can export their data, set a spend-alert threshold, manage email notifications, and delete their account and associated videos, jobs, and history.
Usage limits: Videos consume credits based on compute; the pricing page estimates roughly 30 to 70 credits for a short video and 80 to 200 for a max-reliability run with a premium narrator.
Support: The pricing page lists email support, and the site provides [email protected] as a contact address.
Availability: The hosted service is in closed beta, with invite codes required for access and a waitlist for people without an invite.
Price from: $25/mo
