name: cognee-cli description: Use when the user wants to drive cognee from the terminal with cognee-cli — remember/recall/forget/improve memory commands, managing datasets and config, or database migrations.

Use the cognee CLI

cognee-cli ships with the package (entry point in cognee/cli/_cognee.py; each command lives in cognee/cli/commands/). Every command has --help for its flags, but only a few (demo, memify, eval, serve, push, upgrade, downgrade, stamp, and search with one CODE example) include usage examples — for the memory commands use the examples in this file. Needs LLM_API_KEY configured, same as the SDK.

Core flow

The memory commands are the primary surface as of cognee 1.x:

cognee-cli remember "Your text here"         # also accepts file paths / URLs
cognee-cli remember ./docs --dataset-name my_project
cognee-cli recall "Your question"            # query the graph
cognee-cli recall "keyword" --query-type CHUNKS
cognee-cli forget --all                      # wipe local state

remember is ingest + graph build in one step (add + cognify under the hood); --background/-b runs the cognify stage in the background, and --dry-run estimates LLM tokens/cost without ingesting. recall takes --datasets/-d, --top-k/-k (default 10), and --session-id/-s.

forget targets --dataset, --dataset-id, --data-id (needs a dataset), or --everything/--all — one unified command replacing the older delete and empty-dataset paths. --memory-only (with a dataset) drops the graph and vectors but keeps the raw files, so the data can be rebuilt.

forget --all does not ask for confirmation. It deletes every dataset immediately, even on a non-interactive stdin. The legacy delete --all prompts Delete ALL data from cognee? [y/N] first, so switching to forget silently drops that safety net — script it with care.

--query-type accepts 10 of the SDK's 20 SearchType values — the list in cognee/cli/config.py:SEARCH_TYPE_CHOICES: HYBRID_COMPLETION, GRAPH_COMPLETION, RAG_COMPLETION, CHUNKS, CHUNKS_LEXICAL, SUMMARIES, CODE, CYPHER, GRAPH_REPORT, SKILLS. The rest (TEMPORAL, TRIPLET_COMPLETION, GRAPH_COMPLETION_COT, AGENTIC_COMPLETION, NATURAL_LANGUAGE, …) are SDK-only, e.g. cognee.recall(q, query_type=SearchType.TEMPORAL).

When --query-type is omitted the CLI uses HYBRID_COMPLETION (DEFAULT_SEARCH_TYPE), whereas the SDK's cognee.recall() auto-routes between search types. --top-k defaults to 10 on the CLI and 15 in the SDK.

Session memory and enrichment

Session entries are currently written from the SDK — cognee.remember(..., session_id="chat_1") — not the CLI (cognee-cli remember has no session flag). The CLI side of session memory is reading and bridging:

cognee-cli recall "question" -s chat_1       # session cache first: without -d/-t
                                             # this searches the session directly
cognee-cli sessions get                      # retrieve session Q&A history
cognee-cli improve -d my_project -s chat_1   # bridge session content into the graph
cognee-cli improve -d my_project             # enrich/index the graph (no session)
cognee-cli feedback ...                      # attach feedback to results

improve also takes --node-name, --feedback-alpha (learning rate in (0, 1]; default IMPROVE_FEEDBACK_ALPHA, 0.1), --build-global-context-index, --build-truth-subspace (both opt-in stages; the truth subspace needs -s), and --background/-b. It prints one line per stage — name, status (completed / already_completed / skipped / errored) and the skip reason (e.g. no_session_ids, lock_held, triplet_embedding_disabled). remember/improve build their graphs through cognify(), so cognify-level settings (e.g. CONTRADICTION_DETECTION=true) apply to them too.

Legacy / lower-level commands

add, cognify, search, memify, and delete still ship and are what the memory commands call underneath. Use them only to drive a single stage in isolation; prefer remember/recall/forget/improve otherwise.

cognee-cli add "text" && cognee-cli cognify  # what `remember` does in one step
cognee-cli search "question"                 # `recall` minus routing/scope/session sources
cognee-cli memify -d my_project              # custom extraction/enrichment tasks
cognee-cli delete --all                      # superseded by `forget --all`

Management

cognee-cli datasets list                     # dataset operations
cognee-cli config get [key] [--show-secrets] # view one/all settings (API keys masked by default)
cognee-cli config set <key> <value>          # set + persist to ./.env in the cwd
cognee-cli config unset <key>                # reset a key to its default (also persisted)
cognee-cli -ui                               # launch API server + UI (see cognee-server skill)
cognee-cli serve --url http://localhost:8000 # connect CLI/SDK to a running instance

Database migrations

cognee has two migration chains: the relational schema (Alembic, in cognee/alembic/) and the graph/vector data chain (slugs registered in cognee/modules/migrations/registry.py). Both run automatically — at API server startup and on the first write (remember, add, cognify, improve, …) in an SDK/CLI process — unless ENABLE_AUTO_MIGRATIONS=false. So you rarely need these commands; they are for inspecting state, disabled auto-migration, and rollbacks. There is no migrate command.

cognee-cli current                    # stamped revision per database (per dataset
                                      # with access control on)
cognee-cli history                    # the data-migration chain, newest first
cognee-cli upgrade                    # relational to head, then data chain to head
cognee-cli upgrade <slug>             # data chain up to and including <slug>
cognee-cli upgrade --alembic <rev>    # pin the relational (Alembic) target
cognee-cli downgrade <slug|base>      # REWRITES DATA; revision is required,
                                      # prompts unless --force; --dataset <uuid>
                                      # (repeatable) limits it
cognee-cli stamp <head|base|slug>     # set the stored revision WITHOUT running
                                      # anything; prompts unless --force;
                                      # --dataset <uuid> (repeatable) limits it

The positional revision is always a data-chain slug; the relational target goes through --alembic. downgrade leaves the relational schema alone unless you pass --alembic. upgrade runs even when ENABLE_AUTO_MIGRATIONS=false. --alembic-path (or COGNEE_ALEMBIC_PATH) points at a custom Alembic scripts directory.

Gotchas

• The CLI initializes cognee lazily; the first command in a fresh environment is slow (DB + model setup), later ones are fast.
• remember (and add) without --dataset-name targets the default dataset main_dataset; recall/search operate across your accessible datasets unless a dataset is given.
• forget refuses to run bare — pass --dataset, --dataset-id, --data-id (with a dataset), or --everything/--all.
• Session commands (recall -s, sessions get, improve -s) require CACHING=true (the default) — with it off, session reads return nothing and SDK session writes raise. To cut read latency and token cost while keeping session memory, cognee-cli config set AUTO_FEEDBACK false — by default cognee makes one structured-output LLM call per answered query to self-tune its memory.
• memify requires one of the arguments -d/--dataset-name --dataset-id
• config set/config unset write to the .env file in whatever directory you run the command from (creating it if missing). config reset (reset all keys) is still not implemented.
• Which .env actually wins is not always the cwd one. At import, cognee calls dotenv.load_dotenv(override=True), which resolves relative to the cognee package location, not your working directory. In a source/editable checkout (uv pip install -e .) a .env at the repo root therefore shadows the .env in the directory you ran from — and because override=True, it also beats variables you exported. Symptom: config set appears to do nothing, or the CLI connects to a backend you thought you had overridden. To test against different settings, move the repo .env aside, or set values programmatically after import (cognee.config.set_*). (Under python -c the cwd .env does win, because dotenv falls back to the cwd when __main__ has no __file__ — which is why the same command can behave differently as a script vs. -c.)
