Cerul
Semantic video search with timestamped evidence for agents and local libraries.
Cerul is a solid pick if you need local-first video search with citable evidence, especially for agents. It's cheaper than alternatives and privacy-friendly, but cloud features like visual indexing and paid billing are still pending, so production-scale cloud teams should wait or supplement.

About Cerul
Cerul is a video memory infrastructure that helps AI products and individuals understand, remember, and retrieve exact moments from video. It indexes the full content of your videos—spoken words, visual scenes, and on-screen text—so you can search by meaning, not just captions. For developers, it offers a single REST API endpoint, POST /v1/search, that returns timestamped evidence with relevance scores (0.0–1.0), start/end seconds, quoted text, and locator URLs, enabling AI agents to cite specific moments with confidence. For individuals, Cerul Desktop for macOS (Apple silicon) indexes local folders, YouTube channels, and podcasts entirely on your machine—no account, no uploads, and nothing leaves your Mac. Press Alt+Space to open a global search overlay and jump straight to the moment in any video. The platform includes a free desktop tier with a 10-hour local library, unlimited local semantic search, and 20 MCP/agent calls per day, plus paid tiers (Go and Pro) for larger libraries, more daily calls, large local models, and multi-device sync. The Cloud API is in early access, offering upload, speech indexing, search, and clip export on a pay-as-you-go basis, with paid billing, hosted MCP, cloud acceleration, and visual indexing marked as coming soon. The pricing page clarifies that cloud processing runs only for assets you explicitly choose, and local search remains unlimited even when you hit library limits—only new indexing is blocked, while existing content stays searchable. Recent changelog updates (August 2026) show active development: Desktop v0.0.93 added manual single-video cloud upload with explicit confirmation, improved local/cloud routing, and retry recovery to prevent silent execution location changes. The web console was redesigned with clearer navigation for API keys, Playground, usage, billing, and logs, and Desktop settings were split into focused surfaces for models, storage, usage, advanced controls, downloads, and updates. These updates ensure you always know where your processing runs and give you fine-grained control over your data.
Behind the Verdict
Cerul's core strength is its focus on grounded, timestamped evidence. The API returns not just a hit but a quote, start/end seconds, and a locator URL, which makes it genuinely useful for AI agents that need to cite sources. The local-first approach is also a differentiator—you get unlimited local search on a free tier, and nothing leaves your machine unless you explicitly choose to upload to the cloud. The Alt+Space overlay is a smooth way to jump into a video moment, and the recent v0.0.93 update adds manual cloud upload with confirmation, so there are no surprises about where processing happens. However, Cerul is not a finished cloud product. Many features are 'coming soon' without a date: visual indexing, paid API billing, hosted MCP, and SSO/SCIM for enterprise. The desktop app currently only runs on macOS Apple silicon, so Windows or Intel Mac users are out of luck. There are also no pre-built integrations with Slack, Notion, or other common tools, so you'll need to build your own workflow. For a developer experimenting with video search on a Mac, Cerul is worth a try. For a team needing a production cloud service with SLAs, it's not ready yet.

Real-world workflow fit
Concrete scenarios for the personas Cerul actually fits — and what changes day-one when you adopt it.
You index a set of YouTube lectures using Cerul Desktop, then call the local REST API or MCP from your agent to answer questions with timestamped citations.
Outcome: Your agent returns answers with exact quotes, start/end seconds, and locator URLs, enabling verifiable responses without cloud latency.
You point Cerul Desktop at your local folder of conference recordings and use Alt+Space to search for concepts across hundreds of hours without uploading anything.
Outcome: You find the exact moment a speaker mentioned a topic, jump to it instantly, and keep your data entirely on your Mac.
You index internal demo videos and use the Cloud API to build a search feature for your support team to find tutorial moments.
Outcome: Support agents search by plain language and get clip exports with timestamps, reducing time spent scrubbing through videos.
Use Cases
- Search internal video libraries for specific product demos or whiteboard sketches
- Ground an AI agent's answers in timestamps from YouTube lectures or podcasts

Featured Head-to-Head Comparisons
Cerul vs Presto Voice
These tools serve completely different needs. Presto Voice is for QSR chains wanting to automate drive-thru ordering and boost revenue through upselling, with recent adoption by Dairy Queen. Cerul is a video search API for developers needing to find moments across speech, visuals, and text. Choose Presto Voice if you run drive-thru operations; choose Cerul if you need to query video content semantically.
Cerul vs Screenplayiq
ScreenplayIQ and Cerul serve completely different users. ScreenplayIQ is for film professionals who need AI to predict script box office potential, while Cerul is for developers and teams who need to search video content by meaning. Neither replaces the other; choose based on whether your problem is screenwriting or video retrieval.
Cerul vs Truleo
Choose Truleo if you are a law enforcement agency drowning in siloed data and manual case research; its automated intelligence briefings and report writing cut hours from investigations. Choose Cerul if you are a developer or AI agent builder needing to ground models in video content with multimodal search; its API and open-source options offer flexibility but lack pre-built integrations. These tools serve fundamentally different domains—there is no direct overlap.
