The right alternative depends on what you are replacing: price, AI quality, integrations, enterprise controls, or workflow focus. Start with the closest competitors, then use the related guides to narrow the decision.
A Mac-native, bring-your-own-model writing assistant available in any app
4.0
Kerlig offers selection-based writing, document chat, local models, and hundreds of model choices for a one-time license, but buyers must budget separate tokens and understand macOS permissions and provider data paths.
A bring-your-own-key AI workspace for chatting with multiple model providers
4.1
TypingMind unifies multiple AI APIs in a local-first interface, but API spend, browser storage, optional cloud services, and provider policies determine its real value and privacy.
System-wide voice dictation with local and cloud transcription options
4.0
Superwhisper turns speech into formatted text across desktop and mobile apps, with local-model options and unusually clear trust material, but accuracy, latency, consent, and fair-use limits still need testing.

When to switch
Look for an alternative if Alter is too expensive, lacks the integrations you need, or is not strong enough for your primary workflow.
What to compare
Compare output quality, setup time, pricing limits, supported models, API access, and whether the tool fits your team’s existing systems.
Best next step
Shortlist two options, run the same real workflow through both, and keep the one that reduces rework rather than the one with the longest feature list.
