That depends on you. Again: There is a whole slew of very much overlapping productivity apps out there. People are getting hyper specific about minute features and how they want the UX to feel, exactly. (EDIT: To illustrate this point, a friends choice of note taking app recently boiled down to the availability of (A) text background colors in (B) sufficient amounts and color variety with (C) good enough black-on-text-bg-color-contrast.)

As with every moderately sized app, there is bound to be a number of things that Pitch has its own spin on. Different enough for you to matter? Maybe not. Different enough for someone else to matter? Probably yes.

Knowing Google history in shutting down anything other than search, mail and maps, yes its a huge advantage. I was approach to use “Authenticator” app in new project and upon finding out its Google, I declined

Google authenticator is just TOTP. The whole "scan a QR code, type the number" thing will work with any client, not just Google's app.

I'd say a VC-funded presentation startup is a fair bit more likely to shut down than one of Google's core products is.

One of Google core product? AFAIK, Google itself has _one_ core product, and only one, which is Ads. The rest are services meant to sell more ads, or get more user data so the ads are more effective.

Other products are usually spin out into their own companies and/or under Alphabet rather than Google.

Google is never going to close slides or docs. Gsuite makes them enterprise money.

Don't be so sure. Yeah, G Suite makes them money, free Google Slides or Docs doesn't.

After seeing them close down a couple of services I never thought they would close down, I don't think anything "free" is off-limit right now. Especially depending on how the US/world economy goes.

Would you bet on Google never closing Slides? I wouldn’t.

I'll bet it's still here in ten years. Fifteen if there are no dramatic technological shake ups.

I know Google kills off stuff left and right, but Gsuite has huge penetration in business and academia. Slides are a part of that.
