The short answer
Tella is a studio for videos you present: you record in clips, then edit and host them there. Its Auto Capture beta has an AI agent film a web app on a public domain, without narration. With tday, your coding agent records your app on your machine, localhost included, and tday adds an AI voice and captions. As of November 2026, Tella Pro is $26 per user a month, or $13 billed yearly, with no free plan. tday is free for 5 saved demos, and Pro is $39 a month.
Key takeaways
- Both let an AI agent do the filming, and they mean different things by it. Tella's agent opens your app at a public address. With tday, your own coding agent runs your app from its repo.
- Tella's Auto Capture "can't record localhost, IP addresses or intranet hosts, desktop or mobile apps". tday records an app running on your machine: localhost, desktop apps, and phone apps in a simulator or emulator.
- Tella does not generate AI narration. tday voices every line and lets you rewrite any of them as text.
- Tella is the better tool for videos with a person in them: courses, updates, social clips.
- Tella has no free plan, only a 7-day trial. tday's free plan includes 5 saved demos.
Accurate as of . Every fact about Tella was read from its own website that day, and each page is listed under Sources. Prices and plans change, so check the vendor's page before you buy. tday publishes this blog and makes one of the two products compared.
Of all the screen recorders, Tella has moved closest to what tday does. In October 2026 it launched Auto Capture, where an AI agent films a demo of a web app with nobody at the keyboard. That is tday's premise too.
But the two agents stand in different places. Tella's is outside your product, reaching it over the internet. With tday the agent is your own coding agent, inside the repo, running the code. What each can film follows from where it stands.

Where Tella is the better choice
Videos with you in them. A course, a product update, a founder's walkthrough. Tella records in short clips you can redo and rearrange, with camera layouts and speaker notes as a teleprompter.
Editing by asking. The Tella Agent is a chat in the editor that makes the edit you describe, and Tella Motion builds motion graphics.
A product you do not have the code for. Auto Capture needs only an address. tday needs the repo and a coding agent, except on Enterprise, where it can record in the cloud.
Viewer analytics. Tella tracks views, unique viewers, watch time and where viewers came from.
Developers get the keys on every plan. The API, webhooks and an MCP server with more than 100 tools come with Pro and the trial.
Where tday is the better choice
Unreleased features. The feature you most need a demo of is the one that shipped today, or has not shipped. It is on localhost. Auto Capture cannot go there, unless you put the feature on a public preview deploy. Your coding agent is already there.
Narration. A silent screen capture is half a demo. tday writes the take as narrated lines, voices each one, and adds captions. Tella's help center says it "can't record a voiceover onto a video you already recorded or generate AI narration".
More than the web. Electron apps, terminal tools, phone apps in a simulator and Mac apps.
Demo data. With tday, your agent starts a separate copy of your app with throwaway data, and the take is checked for secrets on your machine before anything uploads.
Staying current. A re-record becomes a new version of the same demo, so the link and every docs embed play the new take.
What each one costs
Tella charges per user. Pro is $26 a month, or $13 a month billed yearly. Premium is $39, or $19 billed yearly, and adds a custom domain, 4K sharing and the removal of Tella's branding from share pages. There is no free plan: a 7-day trial of Pro, no card needed, and after it you can still watch and share your videos but not record, edit or export. Auto Capture is included with paid plans, and a trial cannot start a take.
tday charges per plan. Free includes 5 saved demos and 100 credits a month, which is 10 minutes of voiceover. Pro is $39 a month for 2 seats, 25 saved demos and 500 credits. Growth is $149.
Which should you pick
If a person is presenting, use Tella. It is very good at that, and it is not what tday is for.
If the product is the presenter, and especially if the feature is still on localhost, use tday.
Frequently asked questions
Can Tella record localhost?
Tella's normal recorder films whatever is on your screen, localhost included. Its Auto Capture agent cannot. Tella's site says Auto Capture "can't record localhost, IP addresses or intranet hosts, desktop or mobile apps". With tday, your coding agent records an app running on your machine, so localhost is the normal case.
Does Tella have a free plan?
No. As of November 10, 2026 Tella offers a 7-day trial of Pro with no credit card. Its help center says there is no forever-free plan: without a subscription you can view and share existing videos but cannot record, edit or export.
Does Tella have AI voiceover?
No. Tella's Auto Capture page says: "Does Auto Capture add a voiceover? No. Tella doesn't generate AI narration." It records your own voice, and translates subtitles into up to 10 languages per video. tday voices every narrated line with an AI voice.
Is tday a Tella alternative?
For product demos recorded by an AI agent, yes: with tday, your coding agent can film localhost, desktop and phone apps, and tday narrates the result. For videos a person presents, such as courses and updates, Tella is the better fit.
