Q: Subject: Clarification Requested on AppSumo Lifetime Plan and “Unlimited Advanced AI” Access
I purchased the AppSumo lifetime plan for Logically AI. My understanding is that this plan includes Unlimited Advanced AI, but when I try to use it, I am prompted to pay for an upgrade.
Please confirm whether Unlimited Advanced AI is included in my AppSumo entitlement. If it is, please restore access. If it is not, please identify the specific term or exclusion that explains why this feature is unavailable on my plan.
Please also confirm whether this is an account entitlement error, billing issue, or change in plan scope.
Thank you.

Q: The deal was UNLIMITED use for standard models... Yet, Why was it still limited?
I dunno who to vent out my anger on as I felt like I got scammed and cheated... Like... Why did you offer "Unlimited" usages for standard models for Tier 1 if you can't honour that promise?
Beside coming to this page to vent out, I don't know what else to do because it's too late to ask for a refund now!

I thought it was merely a temporary glitch! There is nowhere to voice my concerns. What does this below imply? They are exploiting AppSumo's customers through mere wordplay. Yet, there remains a company offering a similar service that honors its commitments. This is truly unjust.

@Abah Can you confirm that the upload file size is restricted to 10 MB ?
In my case, in reference manager ➜ Upload, it says Max. 100MB or 2 000 pages per file

hides between suspect appsumo policy
Note: AppSumo LTD users are not able to change their emails due to AppSumo policy preventing reselling of LTD accounts.
- appsumo lets uses change their email address

Weaponized "Fair use"-policy
Hello,
Afforai/Logically was my first Appsumo deal, and it’s currently ending in a major disappointment on the part of both Appsumo and Logically.
The fact that the “unlimited” promise couldn’t be kept should be obvious to anyone when it comes to AI products, but the flow of information—or rather, disinformation—from Logically is unbelievable.
Master plan to get rid of LTD:
1. Change the name
2. Reduce the “unlimited” promise to, say, 50 calls per day and XX storage.
3. Get rid of the BYOK feature so users are trapped in the ecosystem.
4. Abuse the “Fair Use” policy to pressure LTD users into using the subscription that arrives unprompted via email every month and gives you a 50% discount on the features you previously had.
My conclusion:
If Appsumo offers a refund (in this case, because of the BYOK), take it and run!
Yeah, too bad... good product/deal, but incompetently managed—or “good,” if you look at the other CEOs and their behavior.
For me, that deal is a lost cause.

Shocking limits now...
As all have been described here, an "unlimited" use of AI, even the lower-end models now becomes limited. Just two queries and then nothing can be used - yes just like a free trial. Worse part, they took away the BYOK where we can continue even if that is so.
After initial extraction from the LTD, this rebranding just show us what the founders are interested in - upselling, rent-seeking without additional value added. What's the use of so many new models or mini tools when it can't be used?
Anyway, if you are still looking, AnythingLLM can be a good replacement for this. Free desktop app with BYOK that can do RAG as well as agentic work.

Does Logically cheat and fraud?
I purchased Afforai tier-1 with unlimited standard AI, but after changing to Logically, a standard AI became limited and of poor quality. Why?
After a few chats, it prompted lstandard ai imited. Logically lifetime tier 1 becomes useless, the same as the free version.

Clarification of changes to credits
In the old Lifetime deals last year, we used to have the credits system and it was used for 3 things:
- File upload processing
- Al usage inside Afforai
- Al usage outside Afforai via APIBut since we updated our subscription plans back in April, we worked with the AppSumo team to update our LTD plans to honor the agreement that all LTD users will get updates matched to our Pro Subscription Plan.With this updated LTD plans, all T1, T2, T3 LTD users get UNLIMITED queries or AI usage inside Afforai that was not being the case in the old LTD plans last time. We’ve also made file uploading credits gone, Al usage credits gone. Meaning there’s no more...
