What each plan includes

PDF parsing currently has no cumulative monthly limit on the number of files or pages on Pro, Premium, or Premium+. Parsing does not use AI credits, so there is no monthly parsing allowance to wait to reset. Each PDF must be no larger than 350MB and have no more than 3,000 pages to be parsed. For PDF uploads, Pro has very high limits, while Premium and Premium+ have unlimited uploads. Premium+ has the same features as Premium, with more AI credits.
Monthly credit allowances and supported models may change. New provider models are not automatically available in Heptabase.
What uses AI credits?
AI credits cover the AI Agent, AI Tutor, video transcripts, Insight generator, and voice notes. PDF parsing does not use AI credits.
PDF parsing extracts text from PDFs, including scanned text through OCR, so AI can read them. It does not create Highlight cards. To make a Highlight card, select a passage while reading the PDF.
You can keep using voice notes after your AI credits reach zero. Voice notes use credits whenever you have credits available.
Do unused AI credits carry over?
No. Unused monthly AI credits do not carry over. Go to Settings → AI Features → Usage to check your remaining credits and next reset date.
Free trial
The subscription trial lasts seven days. No matter which plan you choose, the trial includes unlimited PDF uploads and parsing, plus the same AI credit allowance as Premium.
Using all your trial AI credits does not end the trial or start billing early. You can choose to end the trial early and start your paid subscription right away. When your paid subscription starts, your AI credits reset to the allowance for your selected plan.
When you need more AI usage
After your included AI credits run out, you can:
Upgrade to Premium or Premium+. Upgrading from Pro gives you more AI credits and access to the OpenAI and Anthropic models supported by Heptabase.
Enable on-demand usage. On a paid subscription, turn it on in Settings → AI Features and set a monthly spending limit. On-demand charges start after your included credits run out. You can then continue using AI Tutor and other features that use Heptabase AI credits. On-demand usage is not available during the free trial. Read the on-demand usage guide.
Use your own API key. Connect an OpenAI or Anthropic key for the AI Agent. This does not apply to AI Tutor. Set up your API key.
Sign in with Codex. Use supported models in the AI Agent, even after your Heptabase credits run out. This does not currently apply to AI Tutor.
Basic models on Premium and Premium+
After your included credits run out, Basic models can still read, search, and answer for free. To create or edit content, you need on-demand usage enabled with enough remaining allowance. For Basic models, on-demand charges apply only if the AI Agent successfully changes content. Read-only conversations remain free.
Changing your plan
Subscription charges and AI credits are separate. A prorated charge or account balance credit is not an AI credit balance. Before you confirm a plan change, review the charge, effective date, and Total due today. After the change takes effect, check Settings → AI Features → Usage for your updated credits and next reset date.
Change | Where to make it | What to know |
Switch between monthly and yearly billing on the same tier | Manage Subscription | Check Usage after the change. The payment amount and annual renewal date do not tell you your AI credit balance or reset date. |
Upgrade to a higher tier | In-app upgrade flow | If you keep the same billing interval, the billing cycle does not restart. The charge accounts for the remaining time and unused value of your current plan. |
Downgrade to a lower tier | Manage Subscription | Once the change takes effect, check Usage for your updated AI allowance. |
Do not rely on repeated plan changes to get extra AI credits. If a specific credit balance or reset date affects your decision, contact in-app support before changing plans. Support can also help with other plan-change questions.
