Valmera vs Cardboard: the same promise, two different editors
Cardboard and Valmera make nearly the same claim in nearly the same words: an agentic AI video editor in your browser — describe the edit, it cuts, captions, reframes and composes your real footage. The difference shows up one level down. Cardboard is a shared editor your team works in, with serious AI doing the heavy lifting. Valmera is an agent you hand the whole job to, which edits, looks at its own rendered frames, and returns one finished video. Everything below was checked against both vendors' own pages on 8 August 2026.
If your bottleneck is a team working on footage together — several people cutting, commenting at timecodes, searching hours of material for the right moment, then delivering in more than one language — Cardboard fits that shape better: real-time collaboration, footage search, caption translation and AI dubbing are all first-class there and absent in Valmera. If your bottleneck is the edit itself — you have one recording and want to type a paragraph and get back a finished, source-quality video without ever seeing a timeline — Valmera is built for exactly that: the agent performs the whole edit, checks its own frames, and its replies are verified against what was actually done to the file. Same category, opposite centres of gravity.

Cardboard — a collaborative browser editor with an agent inside
Cardboard's own description is "an agentic AI video editor in your browser — describe your edit and Cardboard cuts, captions, reframes, and composes it", and the feature set around that sentence is what separates it: the product watches and indexes your footage so you can search hours of material for quotes, reactions, people and emotions in plain language; it reframes one video into vertical, square and landscape versions; and it is built for teams — shared projects, comments at exact timecodes, and real-time collaborative cutting. Around the edit it stacks delivery features: caption translation across languages, AI voice dubbing, audio cleanup, ducking, volume levelling, colour grading, a built-in background music library and per-platform export presets.
The honest way to read Cardboard: it is an editor first — one your whole team stands in — with an increasingly capable agent working alongside you.
Valmera — an agent that owns the edit end to end
Valmera has no collaborative timeline to stand in, on purpose. You upload one file — up to 14 GB or 3 hours — and describe the outcome in plain English. The agent indexes the footage, then performs the entire edit as a versioned edit decision list: silence and filler cut, word-timed captions, punch-ins that land on the right words, speed ramps, transitions, colour grade, reframes to 16:9, 9:16, 1:1 or 4:5, watermark and object removal. Music is not picked from a bundled library — the agent searches the open web for licensed tracks (every result carries its license label), can hunt down a specific song you name, and ducks and masters it under speech. Sound effects are real recorded sounds fetched from the web, and topical b-roll — mention a rocket launch, see the rocket — is sourced the same way. Then it renders a preview, looks at the frames it actually produced, corrects what is wrong, and exports from your original file at source quality.
The same toolset is published as a remote MCP server with 100+ tools, so Claude or any MCP client can drive real edits — the Valmera MCP server is the same engine with your agent in the chair.

The workflow difference, concretely
Give both products the same hour-long interview and the same goal — a tight, captioned, graded cut for YouTube.
In Cardboard, you (and your editor, and whoever else has the link) open the project together. You search the footage for the segments worth keeping, let the AI reframe, caption and clean up audio, drop comments at 14:32 where the cut feels late, and iterate in the editor until it is right. The product's value is how much of the manual work the AI absorbs while the humans stay in creative control.
In Valmera, you type the paragraph — "cut the dead air and tangents, punchy pace, captions in the house style, punch in on the strongest lines, warm grade, something moody under the intro, keep it under twelve minutes" — and the agent does all of it, shows you a preview it has already inspected frame by frame, takes your corrections in plain English, and exports from the original file. The product's value is that nobody on your side opens an editor at all.
That is why the collaboration rows in the table point one way and the autonomy rows point the other: each product spent its effort exactly where its theory of the user says the work should happen.
Pricing, as published on 8 August 2026
Cardboard runs every plan through a 3-day free trial; plans are credit-based with built-in weekly and monthly usage limits, and additional credits can be purchased at any time. Current plan prices are on their pricing page.
Valmera starts free — $0, 50 one-time credits, no card — then Creator $30/month for 2,000 credits, Pro $50/month for 4,000, and Frontier $100/month for 10,000, each paid plan opening with a 3-day trial. Credits meter the AI work an edit takes, so a light trim costs little and a full agentic edit with music, b-roll and grading costs more.
Choose Cardboard if · Choose Valmera if
Cardboard
A team cuts together in real time · you need to search hours of footage for moments · captions must ship in several languages · you want AI dubbing · you want a built-in music library and per-platform export presets · you want to stay hands-on in an editor while AI does the heavy lifting.
Valmera
You never want to open a timeline · one plain-English brief should come back as one finished video · the export must come from the original file at source quality · you want the agent to verify its own frames · you need a specific song found on the open web, real sound effects, or topical b-roll fetched on mention · you want your own AI agent editing over MCP.
