Bae vs Professor Goose

Bae and Professor Goose are both lifestyle tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Bae

Bae lets you create multiple AI companions with distinct personalities and have ongoing conversations that accumulate personal history over time. The free tier gives you a daily message limit and multiple companion slots, which is enough to test the format and see whether the memory model holds up across sessions. The ceiling arrives fast: permanent memory, which is the core differentiating feature, is a paid-only capability. Without it, the relationship continuity the platform is built around does not fully exist. Adult content is also paid-only. For users who hit that wall and want persistent, intimate companionship, upgrading is the only path — there is no workaround on the free tier.

Professor Goose

The tool takes uploaded content — PDFs, typed notes, syllabus topics — and generates questions designed to surface what you cannot yet explain, not just what you have not read. It fits concept-heavy subjects where understanding chains matter: explain supply curves wrong and the follow-up question will catch it. The free tier runs on a shared usage allowance, so heavy daily sessions can hit a ceiling before a study block is done. There is no API, no self-hosting, and no way to pipe it into a broader study platform — what you see in the browser is what you get.

Pros	Multiple companion slots are available on the free tier, so you can test different personalities and archetypes before committing to the paid memory layer. Persistent memory on the paid tier means companions carry forward personal details across sessions, which means the conversation on day thirty actually references what you shared on day one instead of starting over. Explicit support for romantic and intimate relationship dynamics in a private, contained environment, so users exploring those scenarios do not have to work around content filters designed for general-purpose assistants. No integration complexity or technical setup — the platform is fully managed and browser or app-based, so there is no infrastructure overhead standing between you and the companion experience.	Socratic follow-up questions respond to what you wrote, not a generic rubric — so a half-correct answer about price elasticity gets probed on the part you missed, not marked wrong and moved on. PDF upload and syllabus mapping let you anchor sessions to your actual course material, which means the questions stay relevant to what will be examined rather than drifting into adjacent topics. Active recall by default — every session requires you to produce an explanation, not recognise one — so you find out before the exam which concepts you only think you understand. Progress tracking across sessions surfaces which topics you keep stumbling on, so you can redirect study time instead of repeating sessions that felt comfortable.
Cons	Permanent memory is a paid-only feature, which means the free tier structurally cannot deliver the long-term relationship continuity that is the platform's core value proposition — free users are testing a diminished version of the actual product. Adult content is gated behind the paid tier, so users who create companions specifically for intimate interactions and start on free will hit a hard content wall before the relationship develops, with no workaround. There is no API and no self-hosted option, which means any user or team that needs data portability, conversation export, or control over where their data lives has no path forward — and at that point the only real alternative is moving to an open-source LLM stack they control entirely. The platform is a single-purpose consumer product with no integration surface, so anyone who wants companion-style memory as a component inside a broader application or workflow cannot use Bae for that purpose — the architecture does not support it.	The free tier runs on a shared usage allowance: a two-hour revision block across multiple topics can exhaust the daily quota mid-session, forcing you to stop or pay — this is a hard wall, not a soft slowdown. No API and no integrations mean the tool cannot connect to Notion, Anki, an LMS, or anything else in your study stack; if your workflow involves syncing review data or building custom pipelines, you are maintaining a completely separate manual step. Teams or educators building structured curricula for multiple students have no admin layer, cohort tracking, or content management — at that point the tool's individual-student design becomes a ceiling and most switch to a platform with instructor controls.
