Chat assistants · alternatives
Reasons to compare Exogram: the pricing page shows no free plan even though the homepage mentions one, Personal is $29 per month with memory capped at 2,000 entries, Builder adds usage charges on top of $149 per month, and Team starts at $850 per month.
Our catalog lists three alternatives, all with free plans: ChatGPT (Plus at $20 per month per user), Claude (Pro at $20 per month per user) and Gemini Notebook, formerly NotebookLM, whose starting price is not stated in our data. They are general assistants rather than dedicated memory vaults with an evidence view.
"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.
Taken from the documented limitations in our Exogram profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Exogram (this page) | $29/mo (Personal) | Yes | Web, API | The pricing page shows no free plan despite the homepage mentioning one, and memory entries are capped per plan. |
| ChatGPT | $20/mo (Plus (consumer)) | Yes | Web, Desktop, Mobile, API | Almost every tool (uploads, images, voice, deep research, Codex) has plan-dependent usage caps that OpenAI states can change over time, and the API is billed separately from every ChatGPT subscription. |
| Claude | $20/mo (Pro) | Yes | Web, Desktop, Mobile, API | All plans have usage limits that reset on a schedule; the paid chat subscription does not include API access, which is billed separately per token. |
| Gemini Notebook (formerly NotebookLM) | Not published | Yes | Web, Mobile | Free tier has standard usage limits and 50 sources per notebook; higher limits need a Google AI Plus, Pro or Ultra plan, which Google says are only available in specific regions. |
